These creatures can serve as reservoir hosts for many zoonotic parasites; therefore, they increase the risk of human infections. The aim of this study was to investigate Toxoplasma gondii and Neospora caninum in rodents caught in Meshgin-Shahr District, Iran.Patients and methods: In a cross-sectional study, brain samples were collected from 70 rodents caught in Meshgin-Shahr District during March and December 2015. The specimens were examined for exposure to T. gondii and N. caninum with molecular methods.Results: Seventy rodents were caught, including 50 Meriones persicus, 11 Mus musculus and 9 Cricetulus migratorius. Thirty rodents were female and 40 were males. Using PCR (B1 gene), T. gondii was detected in 7.1% (5/70) of the rodents while N. caninum was not detected. The prevalence of Toxoplasma infection was higher in female rodents (4.28%) compared to male rodents (2.86%), but the difference was not significant.Conclusion: The results showed a low risk of T. gondii and N. caninum among rodents. Finally, further research is needed to understand the role of these rodent species in the transmission of the above protozoan pathogens to humans and livestock in this area.Keywords: rodents, Neospora, Toxoplasma, prevalence, PCR, Iran

Aim: The aim of the present study was to determine the prevalence and subtype distribution of Blastocystis and its relation with demographic data and symptoms in humans referred to medical centers in Ahvaz 2014-2015. Background: Infections with intestinal parasites are one of the most important threats to human health worldwide, especially in tropical and subtropical areas. Blastocystis sp. is a common parasite of humans with a vast variety of non-human hosts. We aimed to study the prevalence and subtypes of Blastocystis sp. in individuals referred to medical laboratories in Ahvaz city, southwest Iran. Methods: From September 2014 to September 2015, 618 stool samples were collected from 16 medical laboratories in Ahvaz, and examined using direct wet mount, formalin-ether concentration, a modified version of the Ziehl–Neelsen staining technique, and cultivation in xenic HSr + S medium. Subtypes of positive Blastocysts sp. were obtained using the “barcoding” method. The results were analyzed using SPSS software, version 16, with Chi-square and Fisher’s exact test. Results: Totally, 325 (52.6%) of the referred individuals were men and 293 (47.4%) were women. Blastocystis sp. was observed in 146 (23.6%) samples. Co-infections with other intestinal parasites were found in 32 (5.17%) cases. Out of the 146 positive isolates, 20.83%, 20.83% and 58.34% belonged to ST1, ST2, ST3 respectively. Conclusion: Blastocystis sp. was quite common in the study population, with a carrier rate corresponding to nearly one in every four individuals. The subtype distribution identified in the present study was largely identical to that reported from other studies in Iran, with ST3 being the most common.

• To the best of our knowledge, this is the first systematic review of the prevalence of HVL in Iran. • This study found that the pooled prevalence of HVL infection was low in Iran. According to the results, the prevalence of HVL infection has decreased in Iran over the last two decades. • In this study, the highest prevalence of HVL was found in the northern (3%, 95 % CI: 1–5%) and southern (2.1 %, 95 % CI: 1.4–2.8 %) areas of Iran. • However, despite the efforts made by Iranian public health authorities for controlling and preventing HVL, not only new human cases of VL continue to occur in old endemic foci, but also the disease has been reported in new areas where it was non-endemic previously. In this regard, appropriate measures should be taken to control VL and prevent its spread to other areas. Leishmania infantum is the main cause of human visceral leishmaniasis (HVL; also known as kala-azar) in the Middle East and may be fatal if left untreated. This disease was first reported in 1949 in Iran. Despite marked improvements in hygiene and sanitation conditions, the disease is still endemic in some parts of Iran. It is difficult to determine the current prevalence of HVL in Iran due to the scarcity of comprehensive studies in this regard. In response to this gap, a systematic review and meta-analysis was conducted to gain better understanding of HVL epidemiology in the general population of Iran. English and Persian databases were searched for studies reporting the prevalence and risk factors associated with HVL in the Iranian people from January 1995 to December 2019. The reported data were selected according to inclusion and exclusion criteria. The pooled prevalence of HVL infection and its 95 % confidence intervals were calculated. Quality assessment, heterogeneity testing and publication bias assessment were also done. Literature search revealed 3634 studies, of which 35 studies met our eligibility criteria, with a total of 50,716 individuals. The meta-analysis was performed on 31 out of 35 included studies. The estimated pooled prevalence of HVL infection according to seropositivity was 2% (95 % CI: 1–2%) in the general population of Iran in which western and northern provinces had the lowest and the highest prevalence, 0.5 % (95 %CI, 0.2−0.7%) and 3% (95 %CI, 1–5 %), respectively. The seroprevalence of HVL among females (2%; 95 %CI, 1–2 %) was more than males (1%; 95 %CI, 1–2 %). The ≤10 and >10 years age groups had similar seroprevalence rates (1%, 95 %CI, 1–2 % versus 1%, 95 %CI, 0–1 %, respectively). There was no significant difference in terms of geographic area, age and sex. Of 31 studies included in the meta-analysis, the most common diagnostic test was the direct agglutination test (96.77 %). To the best of our knowledge, this is the first systematic review of the prevalence of HVL in Iran. The results showed a low seroprevalence of HVL infection. However, the lack of published reports of HVL in an area does not exclusively mean the absence of the disease or carrier. We therefore recommend further studies in this regard. [ABSTRACT FROM AUTHOR]
