RESUMEN
The public health importance of myiasis [infestation with dipterous (fly) larvae] remains unknown. This disease is spread worldwide in animals and humans, but baseline data on its prevalence are limited. In particular, knowledge on human urogenital myiasis (UGM) is scattered. As such, a systematic search was undertaken of five English and five Persian databases for publications describing UGM cases in English or Persian published between 1975 and 2017. In total, 45 papers reporting 59 UGM cases from various regions of the world are included in this review. All included papers were from the English databases. The age of patients ranged from 5 to 89 years, and the mean age was 40.6 years. Thirty-six of the patients were female and 19 were male. The highest number of cases (n = 12) was reported from Brazil. The most common genera causing UGM were Psychoda spp. (23.7%) and Cochliomyia spp. (11.8%). The vagina was the most commonly reported anatomical location of UGM for women, and the urogenital tract was the most commonly reported location for men. Thirteen cases were reported from rural areas and eight cases from urban areas; the location of other cases was not specified. The incidence of UGM is likely to be substantially underestimated when evaluated based on published case reports. Epidemiological studies, such as questionnaires to medical doctors, could help to gather the necessary baseline data on the occurrence of UGM.

Background: The most important genera of trichostrongylid nematodes that live in digestive tract of ruminants include Teladorsagia, Haemonchus, Trichostrongylus, Cooperia and Marshallagia. Out of the above-mentioned genera, four infect humans including Teladorsagia, Haemonchus, Trichostrongylus and Marshallagia. These parasites are an important part of ruminant pathogens, and some are extremely pathogenic and deadly, and thus vitally important from veterinary viewpoint. Hence, this study was performed to determine the latest status of zoonotic gastrointestinal trichostrongylid nematodes in sheep and goat, in Isfahan province, center of Iran.Materials, Methods & Results: The intestines and abomasums of 109 small domestic ruminants (56 sheep and 53 goats) which were slaughtered at Isfahan slaughterhouses were collected and placed separately in large containers to be transferred to the laboratory. To investigate morphological characteristics, the found nematodes were placed on glass slides appropriately, dyed by lactophenol and azocarmine as a temporary mount. Finally, their genus and species were identified according to morphological characteristics using valid taxonomic keys. Seven species of trichostrongylid nematodes belonged to four genera were isolated from intestines and abomasums of sheep and goats. The found species were Trichostrongylus vitrinus, T. probulurus...(AU)
