Despite an increasing trend in Clostridium difficile infections (CDI) and high C. difficile colonization rate especially among younger children, infants remain quite resistant to the disease. The goals of this study were to distinguish whether there exists a difference in CDI between children with or without diarrhoea, ascertain the prevalence of CDI, and assess CDI severity in children under 3 years with diarrhoea in our institution.A prospective study was conducted from May 2015 to June 2016. Children 3 years of age or younger were enrolled and into two groups. Every faecal sample was tested using a diagnostic two-step screening algorithm including an immunochromatographic test and polymerase chain reaction.The study enrolled 147 children with diarrhoea and 75 control patients. The prevalence of CDI in children with diarrhoea was 2% (3/147), the prevalence of toxigenic C. difficile in the diarrhoeal group compared to the control group was 11.6 % (17/147) vs. 10.6% (8/75) (p.

- Abstract
Treponema pallidum infection can occur during any stage of pregnancy in the case of untreated or insufficiently treated maternal syphilis. Nevertheless, the transmission to the foetus is most probable during spirochetaemia in the early stage of pregnancy. We present the case of congenital syphilis diagnosed in the third month of age. The screening for hepatitis B and syphilis were negative in the first trimester of pregnancy. The mother was diagnosed with urogenital infection in the sixth month of pregnancy, she was treated with acyclovir as herpes genitalis, but likely primary syphilitic lesions would have been the correct diagnosis. She delivered spontaneously a 2,810 g - female in the 40th week of pregnancy. The screening for treponemal antibodies was not done. The infection started with coryza syphilitica in the third month of age followed by skin lesions around the mouth and on the thighs. On admission, the infant's skin changes were significant for congenital syphilis. Anemia, increased liver enzymes and positive non-treponemal and treponemal tests dominated in laboratory findings. RPR was 1:64, ELISA IgM and IgG were repeatedly positive, confirmed by Western blot (antibodies to Tp47, Tp17, Tp15). In clinical samples (from buccal mucosa and from skin lesion) T. pallidum DNA was detected by PCR. The test was positive for one locus from 3 typing genes (TP0548). Either CSF abnormalities or intrathecal synthesis were proven. The infant was treated with ceftriaxone intravenously for 14 days. [ABSTRACT FROM AUTHOR]

- Abstract
We present a fatal course of meningococcal infection. The patient was a seventeen-year-old girl with one-day history of abdominal pain and diarrhoe. At the time of admission, she was unconscious (Glasgow Coma Scale 3), ecchymoses were present on the skin, hypotension with non-palpable peripheral pulsation developed and capillary return was prolonged. Leukopenia, thrombocytopenia, anemia, coagulopathy and severe lactic acidosis dominated in laboratory findings. The girl died of hypodynamic septic shock refractory to the treatment 4 hours after admisson. Neisseria meningitidis was confirmed by a noncultivation method from the spleen tissue and the presence of capsular gene synG by rt-PCR determined the strain belonging to the serogroup W.

Clostridium difficile (C. difficile) plays a minor but important role in paediatrics. The aims of this study were to objectivise data, to show their significance in clinical practice, and to present our experience with the treatment of paediatric patients.A retrospective study was conducted in patients (0-19 years of age) hospitalized for Clostridium difficile infection (CDI) in the Department of Paediatric Infectious Diseases, University Hospital in Brno between 2013 and 2017. Each patient was tested using a two-step diagnostic screening algorithm including immunochromatography and polymerase chain reaction assays.Thirty-five patients with a median age of 10.3 years (range 1-17.5 years) were enrolled in the study. Almost 70% of patients were aged between 6 and 19 years. No risk factor was identified in one patient, 41.6% of cases were patients with malignancy or inflammatory bowel disease, and 2.5% of patients had short bowel syndrome. After targeted CDI treatment, the median time to resolution of diarrhoea was 2.5 days. Metronidazole was used in more than half of cases. Five patients received fidaxomicin, which was well tolerated. Metronidazole failed in three cases. Recurrence after incomplete treatment with metronidazole occurred in one patient. Health care-associated CDI was recorded in 86% of cases. Recurrent CDI was reported in four children (two with malignancy, one with inflammatory bowel dissease, and one with short bowel syndrome).The course of CDI is generally mild in the paediatric population. CDI without a risk factor is rare. Paediatric patients respond well to metronidazole. Fidaxomicin was well tolerated by all patients. We prefer the treatment with fidaxomicin in high-risk groups (immunocompromised condition, inflammatory bowel disease, and short bowel syndrome).

- Abstract
We present the case report of an unvaccinated Czech child with tetanus. The child had not received any vaccines due to its parent's refusal. The disease originated from the wound in the nose caused by a small flat battery. The typical onset of tetanus followed after two weeks, rapidly progressing to respiratory failure with the need for mechanic ventilation despite intensive treatment. The child spent five weeks in the hospital. Mild long-term sequelae persisted 5 months.

- Abstract
Tick-borne encephalitis (TBE) is a serious viral neuroinfection affecting humans in large areas of Europe and Asia. TBE can occur at any age, but only a few reports of TBE in infants younger than 1 year have been published. Here, we report a case of severe TBE in an 8.5-month-old boy presenting with seizures at the beginning of the neurological phase.

- Abstract
Tick-borne encephalitis (TBE) virus is a major cause of central nervous system infections in endemic countries. Here, we present clinical and laboratory characteristics of a large international cohort of patients with confirmed TBE using a uniform clinical protocol. Patients were recruited in eight centers from six European countries between 2010 and 2017. A detailed description of clinical signs and symptoms was recorded. The obtained information enabled a reliable classification in 553 of 555 patients: 207 (37.3%) had meningitis, 273 (49.2%) meningoencephalitis, 15 (2.7%) meningomyelitis, and 58 (10.5%) meningoencephalomyelitis; 41 (7.4%) patients had a peripheral paresis of extremities, 13 (2.3%) a central paresis of extremities, and 25 (4.5%) had single or multiple cranial nerve palsies. Five (0.9%) patients died during acute illness. Outcome at discharge was recorded in 298 patients. Of 176 (59.1%) patients with incomplete recovery, 80 (27%) displayed persisting symptoms or signs without recovery expectation. This study provides further evidence that TBE is a severe disease with a large proportion of patients with incomplete recovery. We suggest monitoring TBE in endemic European countries using a uniform protocol to record the full clinical spectrum of the disease.

- Abstract
Background: Pathogenic treponemes related to Treponema pallidum are both human (causing syphilis, yaws, bejel) and animal pathogens (infections of primates, venereal spirochetosis in rabbits). A set of 11 treponemal genome sequences including those of five Treponema pallidum ssp. pallidum (TPA) strains (Nichols, DAL-1, Mexico A, SS14, Chicago), four T. p. ssp. pertenue (TPE) strains (CDC-2, Gauthier, Samoa D, Fribourg-Blanc), one T. p. ssp. endemicum (TEN) strain (Bosnia A) and one strain (Cuniculi A) of Treponema paraluisleporidarum ecovar Cuniculus (TPeC) were tested for the presence of positively selected genes., Methodology/principal Findings: A total of 1068 orthologous genes annotated in all 11 genomes were tested for the presence of positively selected genes using both site and branch-site models with CODEML (PAML package). Subsequent analyses with sequences obtained from 62 treponemal draft genomes were used for the identification of positively selected amino acid positions. Synthetic biotinylated peptides were designed to cover positively selected protein regions and these peptides were tested for reactivity with the patient's syphilis sera. Altogether, 22 positively selected genes were identified in the TP genomes and TPA sets of positively selected genes differed from TPE genes. While genetic variability among TPA strains was predominantly present in a number of genetic loci, genetic variability within TPE and TEN strains was distributed more equally along the chromosome. Several syphilitic sera were shown to react with some peptides derived from the protein sequences evolving under positive selection., Conclusions/significance: The syphilis-, yaws-, and bejel-causing strains differed relative to sets of positively selected genes. Most of the positively selected chromosomal loci were identified among the TPA treponemes. The local accumulation of genetic variability suggests that the diversification of TPA strains took place predominantly in a limited number of genomic regions compared to the more dispersed genetic diversity differentiating TPE and TEN strains. The identification of positively selected sites in tpr genes and genes encoding outer membrane proteins suggests their role during infection of human and animal hosts. The driving force for adaptive evolution at these loci thus appears to be the host immune response as supported by observed reactivity of syphilitic sera with some peptides derived from protein sequences showing adaptive evolution., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
The national guideline aims to highlight the latest knowledge about clinical manifestations of the infection, to summarize the diagnostic algorithm and to recommend the appropriate antibiotic therapy with respect to evidence-based medicine. The recommendations are consistent with most European guidelines as well as those published by the IDSA. The guideline provides the most recent information on the epidemiology, etiology and pathogenesis of Lyme borreliosis, dermatological, neurological and musculoskeletal involvement, the appropriate diagnostic procedure and prevention. Some information is also provided about post-treatment Lyme disease syndrome. Recommended oral and intravenous antimicrobials are listed in a table showing the doses and duration of therapy. The guideline also mentions diagnostic methods to be avoided or whose results should be interpreted with caution. Although the guideline cannot account for all individual variations among patients, it may provide instructions to physicians in typical and frequent clinical situations.

- Abstract
Acute bacterial meningitis is a severe infectious disease of the central nervous system. Its incidence decreases but lethality and sequelae remain high. The early initiation of appropriate treatment is a factor strongly determining the patient´s prognosis. The authors submit the Czech national guideline for diagnosis and treatment of community-acquired acute bacterial meningitis which has to provide clear and simple recommendations for clinicans involved in the care of meningitis in adults and children. The national guideline was based on the European guideline published in 2016 and adapted for the situation in the Czech Republic. It was acknowledged (approved? ratified?) by the Society for Epidemiology and Microbiology and the Society for Medical Microbiology of the Czech Medical Association.

- Abstract
Objectives: Enteroviruses (EVs) are the most common cause of aseptic viral meningitis. In some cases, they can cause severe meningoencephalitis and acute flaccid paralysis - an association with some virulent serotypes. The objectives were to describe the epidemiological situation of EV meningitis in children in South Moravia, to elucidate the etiology including the incidence of virulent serotypes and to evaluate the clinical presentation., Material and Methods: A total of 88 children with EV meningitis were prospectively evaluated. In case of aseptic inflammation in the cerebrospinal fluid, EV was detected using real-time PCR. Genotyping was performed in 56 samples using repeated one-step PCR and partial sequencing on a genetic analyzer in the National Reference Laboratory for Enteroviruses in Prague., Results: The patients' age range was 3-17 years; there were more boys than girls. Two epidemics occurred, one involving 17 Roma children and the other involving 8 swimming pool visitors. The most common symptoms were headache, fever and stiff neck. The most frequently (59%) detected agent was Echovirus 30 identified as the cause of the epidemics. In one boy, EV 71 (virulent serotype) was found. The clinical course did not vary from that in other serotypes. All 88 children recovered without complications., Conclusions: EVs are an important part of the differential diagnosis of neuroinfections, although most infections are benign aseptic meningitis. The clinical presentation did not vary between infections with various serotypes. Higher incidence rates of virulent serotypes were not reported. Echovirus 30 was detected most frequently and was repeatedly identified as the cause of epidemics throughout the Czech Republic.

- Abstract
Background: The purpose of the study was to evaluate new 3rd-generation test kits, EIA Borrelia recombinant IgM and IgG (TestLine, Brno, Czech Republic), in serum and cerebrospinal fluid (CSF) of children with Lyme neuroborreliosis., Methods: Comparison of three tests was used: the whole-cell EIA from Borrelia garinii (EIA 1) was compared with the EIA using recombinant antigens (EIA 2) and immunoblot. In total, 364 samples of serum and CSF were examined. Eighty-six paired sera and CSF samples were evaluated in the first group of children with Lyme neuroborreliosis. The second group consisted of 30 children with probable Lyme neuroborreliosis. Sixty-six samples from children with neuroinfections other than borrelial etiology were used as controls., Results: In the first group of children with proven LNB, EIA 2 gave significantly more positive results for IgG in serum (P = 0.006; OR = 7.5) as in CSF (P < 0.001; OR = 4.5). There was no statistically significant difference in the IgM positivity of serum (P = 0.54; OR = 0.71). EIA 2 determined significantly (P = 0.001; OR = 0.06) less positive results of IgM in CSF in the LNB patients. IgG antibody index (AI) assessed by both methods revealed similar results (P = 0.646; OR = 1.38). Both methods are comparable, but IgM AI assessed by EIA 2 showed significantly less positive results (P < 0.001; OR = 0.04).The differences in the detection of positive IgM/IgG antibodies in serum and CSF did not reach statistical significance either in the groups of children with excluded LNB or in controls., Conclusions: EIA 2 showed better results than EIA 1 and western blot for the detection of positive IgG antibodies in serum and CSF. The difference in the calculation of AI IgG by EIA 1 and EIA 2 was not noticeable in the group of LNB patients. Comparing IgG and IgM AIs calculated from both tests, the sensitivity for EIA 2 was 68% for IgG and 26% for IgM. The specificity is 100% for both tests.

- Abstract
Study Aim: Analysis of the course of benign acute childhood myosistis during the influenza epidemic of 2012/2013, with a focus on the clinical specificities, laboratory findings, diagnostic and therapeutic approaches, and prognosis., Methods: A retrospective study was conducted of 10 patients with myositis during influenza infection. The haematological and biochemistry parameters were analysed. A direct real time-PCR assay was used to detect the virus from nasopharyngeal swabs., Results: Eight of 10 patients were males of an average age of 7.1 years. Muscle disorders emerged during recovery from influenza. They were characterized by a sudden onset of severe pain in the calf muscles with the consequent inability to walk in nine patients. Toe walking was reported in six children and wide-base gait in one patient. The full blood count showed leukopenia (eight cases) and thrombocytopenia (five cases). Blood biochemistry typically detected elevated muscle enzymes (creatine kinase and aspartate aminotransferase) and elevated myoglobin in all patients. Influenza B was confirmed in all study patients. They all recovered spontaneously within two to four days., Conclusions: Benign acute childhood myositis presents with the clinical picture of transient muscle disorders resulting in difficulty walking and very rarely can be complicated by rhabdomyolysis and kidney failure. It is most often associated with influenza B and affects school age children, mostly males. Good awareness of the condition facilitates the differential diagnosis and enables to rule out other more serious causes of difficulty walking. Symptomatic therapy is an adequate option and the patient recovers spontaneously within a couple of days. Early recognition of the disease avoids unnecessary diagnostic and therapeutic interventions.

- Abstract
Unlabelled: This study of 170 children in the Czech Republic examines the clinical course and sequelae for tick-borne encephalitis. Evaluated were demographic and epidemiological data, signs and symptoms at admission, clinical course during hospital stay and laboratory findings. Cerebrospinal fluid was analysed for white blood cells, protein, impairment of blood-cerebrospinal fluid (CSF) barrier and tick-borne encephalitis virus (TBEV)-specific antibodies. Subjective complaints and objective neurological deficits were investigated. Tick bites were reported in 74 % of the children. The illness had a biphasic clinical course in 58 % of cases. The second phase was characterized by headache in 98 %, high fever in 86 % (more than 38.5 °C), vomiting in 64 % and meningeal signs in 92 % of children. Meningitis (77 %) dominated over meningoencephalitis (13 %). Inflammatory changes in CSF were found in 90 % of children. Immunoglobulin M (IgM) antibodies against TBEV in serum were found early in the infection in 99 %. IgM positivity lasted up to 1,126 days. Neurocognitive abnormalities were found in 19 (11 %) of children. Acquired aphasia, lasting tremor of the upper extremities, speech impairment, inversion of sleep and wakefulness, abnormal hyperkinetic movements and vertigo were found to be permanent but not progressing. Severe sequelae persisted in two children (1 %) while in three (2 %) were classified as mild or moderate., Conclusion: Tick-borne encephalitis in children has a benign course with minimal sequelae. Meningitis with biphasic course is the prevalent involvement and the duration of IgM antibodies in serum and index of positivity are not decisive for postencephalitic disorders.

- Abstract
Comparative analysis of ospC genes from 127 Borrelia burgdorferi sensu stricto strains collected in European and North American regions where Lyme disease is endemic and where it is not endemic revealed a close relatedness of geographically distinct populations. ospC alleles A, B, and L were detected on both continents in vectors and hosts, including humans. Six ospC alleles, A, B, L, Q, R, and V, were prevalent in Europe; 4 of them were detected in samples of human origin. Ten ospC alleles, A, B, D, E3, F, G, H, H3, I3, and M, were identified in the far-western United States. Four ospC alleles, B, G, H, and L, were abundant in the southeastern United States. Here we present the first expanded analysis of ospC alleles of B. burgdorferi strains from the southeastern United States with respect to their relatedness to strains from other North American and European localities. We demonstrate that ospC genotypes commonly associated with human Lyme disease in European and North American regions where the disease is endemic were detected in B. burgdorferi strains isolated from the non-human-biting tick Ixodes affinis and rodent hosts in the southeastern United States. We discovered that some ospC alleles previously known only from Europe are widely distributed in the southeastern United States, a finding that confirms the hypothesis of transoceanic migration of Borrelia species.

- Abstract
We present a case report of a small boy with cystic fibrosis complicated by pertussis and pneumothorax. The child had not been vaccinated against Bordetella pertussis due to the failure to thrive and was infected with the bacterium at the age of 4 months. The course of the disease was severe, with respiratory distress and spontaneous pneumothorax. The diagnosis of pertussis was serologically confirmed. A suspicion for cystic fibrosis increased after an unusually prolonged course of the disease and a history of the failure to thrive. A comprehensive diagnostic procedure revealed Pseudomonas aeruginosa respiratory infection, anemia, pancreatic insufficiency, a positive sweat test and the presence of two CFTR gene mutations. The patient, treated with comprehensive cystic fibrosis therapy, recovered from acute respiratory illness and started to thrive soon.

- Abstract
The article summarizes the latest knowledge about the etiology, epidemiology, pathogenesis, clinical signs, diagnostic procedures and therapy of erythema migrans (EM), a cutaneous form of Borrelia infection. The sole focus on this clinical entity is intentional since EM is the most common clinical involvement in Lyme borreliosis (LB) in the Czech Republic (CR). New genospecies from the Borrelia burgdorferi sensu lato complex, B. lusitaniae and B. spielmanii, as etiologic agents are reported. Although there are no commercial tests available yet for their detection, ticks are demonstrably infected with them in Europe and probably even in the CR. Six pathogenic genospecies circulate among vertebrates and Ixodes ricinus ticks in Europe. The transmission cycle in nature, hosts identified as reservoirs and distribution of borreliae in Europe are presented. Clinical forms of EM are described in detail including accompanying features. Types of erythema in the USA and Europe are compared. In the part on differential diagnosis, allergies, skin and infectious diseases with similar appearance on the skin as EM are mentioned. Although the diagnosis of EM is exclusively clinical and serology is not indicated, methods of direct detection and two-tier testing of antibodies are discussed. There are therapeutic recommendations concerning the choice of antibiotics available in the CR.

- Abstract
The diagnosis of visceral leishmaniasis (VL) is not an easy task. The clinical presentation of VL is similar to lymphomas which have significantly higher incidence in our country. This fact is one of the complications in the diagnosis of VL. Moreover, diagnostic methods have low sensitivity and bone marrow aspiration is necessary. We present a case report of a patient who fell ill in the first year of life and due to atypical lifestyle of his parents was seriously examined after 11 months from the first symptoms of the disease. Many problems with the diagnostic algorithm leading to the definitive diagnosis of VL were encountered. Thereafter, the patient underwent treatment with amphotericin B lipid complex. The course was complicated by febrile neutropenia and anemia, with the necessity for blood transfusion.

- Abstract
We present a case of eye involvement -- intermediate uveitis -- during tick-borne borreliosis in a 10-year-old boy. Ophthalmologic examination revealed impaired vision, apparent thick floating whitish opacity in the vitreous humour of the left eye and fine fibres in the vitreous humour of the right eye. Sonographic examination confirmed hyperechogenic opacity in the vitreous humour. An autoimmune process was suspected but not confirmed. Serological examination showed IgG antibodies against three pathogenic borreliae and borderline values of IgM antibodies against Borrelia garinii were found by immunoblot. The boy was treated with intravenous ceftriaxone for 21 days. The subsequent sonographic examination showed only minute sporadic echogenicity. Biomicroscopically, only residual opacity in the vitreous humour was found. Isolated eye involvement of borrelia aetiology is rare. The discussion provides a review of similar cases of uveitis including diagnosis of the eye form as published in literature.

- Abstract
In 2005, six children were treated in our department who had been in contact with a bat infected with European bat lyssavirus 1 (EBL1). In the Czech Republic, this was the first confirmed case of rabies since 2002, but the fourth case of bat rabies since 1994. All the cases were related to Southern Moravia and bat species which almost do not migrate. This suggests only endemic prevalence of EBL1 in this country. Bat rabies is different from rabies in terrestic mammals. Based on genetic analyses, the lyssavirus genus may be divided into 6 genotypes of which genotypes 1 (rabies virus), 5 (EBL1) and 6 (EBL2) are found in Europe. The infectious cycles of bat lyssaviruses are limited solely to bat populations, in particular the Eptesicus serotinus species and the Myotis genus. Transmission to other mammals is rare. In Europe, four cases of human infection and death due to rabies caused by any of bat lyssaviruses have been reported. Immunologically, bat lyssaviruses are very similar to the common rabies virus. Therefore, the standard prophylactic methods are sufficient. Because of a different natural reservoir, the Czech Republic may be still considered a rabies-free country. However, contacts with bats always pose a risk of rabies.

- Abstract
Objectives: Evaluation of a new kit of the 3rd generation, EIA Borrelia recombinant IgM in the serodiagnosis of Lyme borreliosis (LB) and comparison with the EIA test based on the whole cell antigen in the detection of IgM antibodies., Material and Methods: In total 123 children (147 sera) were examined, 71 children (93 sera) of whom showed clinically defined stage of LB. The other 54 sera of 52 children were tested for suspicion for LB which was later excluded, and for cross-reacting antibodies. They represented the control group of children with other infectious or autoimmune diseases. The EIA B. recombinant IgM kit (Test-Line, CR) is based on the selected antigen fragments: outer surface protein C (OspC) and internal flagellin (p41i). The fragments were selected according to the most frequent Borrelia spp. in the Czech Republic., Results: Samples compared 101/147 (69 %) with both tests showed correspondent reactions. 46 samples reacted inconsistently, 26 from children with LB and 20 from the control group. The total specificity and sensitivity of the recombinant kit in IgM antibody class was 88,9 % and 26,9 %, respectively. In the case of early disseminated LB infection the sensitivity was 35,6 % and it is comparable with the sensitivity of immunoblot. Statistically, there is no difference in the sensitivity (p = 0,101) and specificity (p = 0,383) of EIA B. recombinant IgM and immunoblot., Conclusions: The EIA B. recombinant IgM kit shows comparable diagnostic sensitivity in children with acute LB together with significantly higher specificity in children with non-specific response in kits based on the whole cell antigen and at the same time high conformity with results of IgM class immunoblot. This kit of the 3rd generation is reliable for screening of IgM antibodies.
