This report describes a 49-year-old male construction worker who acquired a Bacillus anthracis infection after working on a sheep farm. He experienced a severe respiratory infection, septic shock, and hemorrhagic meningoencephalitis with severe intracranial hypertension. After several weeks with multiple organ dysfunction syndrome, he responded favorably to antibiotic treatment. Three weeks into his hospitalization, an intracranial hemorrhage and cerebral edema led to an abrupt deterioration in his neurological status. A single dose of raxibacumab was added to his antimicrobial regimen on hospital day 27. His overall status, both clinical and radiographic, improved within a few days. He was discharged 2 months after admission and appears to have fully recovered. [ABSTRACT FROM AUTHOR]

Kingella kingae is a bacterium that colonizes the upper respiratory tract. Despite its low pathogenicity in this location, previous respiratory pathological processes may favor its systemic spread causing bone and joint infections, mainly in children under five years. It can be considered an emerging pathogen in osteoarticular infection in pediatric patients. We report the case of a two-year-old girl with hips pain and limitation of both abduction and extension, and fever. Radiography and ultrasonography were compatible with transitory synovitis; showed scintigraphy inflammatory pathology of the right hip. Articular puncture was performed. The material showed altered biochemical parameters. Microbiological culture yielded isolation of a strain of K. kingae susceptible to beta-lactam antibiotics, azithromycin and trimethoprim-sulfamethoxazole. Blood cultures were negative. The patient was treated empirically with cloxacillin and cefotaxime iv. and continued with amoxicillin-clavulanate orally with osteoarticular improvement.

Background: The object of our research is to analyse the microbiological results of the samples which have been obtained by means of fibronchoscopy (FB) from HIV positive patients from 1991 until 1993., Methods: Sixty fibrobronchoscopies were carried out on fifty-seven HIV positive patients. In every case, samples of bronchoaspirate (BAS), bronchoalveolar lavage (BAL) and telescoping plugged catheter (TPC) were cultured; the last two in a quantitative way. Pneumocystis carinii was investigated in BAL by means of immunofluorescence with monoclonal antibodies., Results: Some microorganisms were isolated in forty-seven bronchoscopies. Thirteen episodes resulted negative. The most frequent etiologic agent was Pneumocystis carinii (seventeen cases). The etiology of fifteen episodes was polymicrobial. The intersticial radiological pattern was the predominant one. It was observed in twenty-seven cases. With regard to immunity, 91% of the patients showed CD4 < 200., Conclusions: In our research work, the samples that have been obtained by means of FB showed a high percentage of diagnoses; that is the reason why we regard this technique as very useful for the diagnosis of pneumonia in patients with AIDS. Due to the large number of bacterian pneumonia, we consider necessary not only the use of BAL, but also that of TPC in these processes.
