Background
Stray cats are considered an important source of various human and animal diseases, particularly diseases of parasitic helminths. We aimed to investigate the distribution of zoonotic species of gastrointestinal helminths in stray cats in Meshkin-Shahr district in Ardabil Province in the northwest of Iran.
MethodsThe gastrointestinal tract of 104 stray cats from villages of Meshkin-Shahr district were provided during 2014-2015. Each gastrointestinal tract was cut into distinct sections, including esophagus, stomach, small intestine, and large intestine, and each section was examined separately for detection of helminths. Helminths were collected and then identified at the species level after clearing and staining.
ResultsOverall, 88 out of 104 cats (84.6%) were found to be infected with at least one gastrointestinal helminth. The rate of infection for each species was as follows: Toxocara mystax (syn. cati) (49%), Taenia taeniaeformis (44.2%), Joyexiella pasqualei (32.7%), Dipylidium caninum (23.1%), Rictularia cahirensis (4.8%), and Physaloptera praeputialis (4.8%). Among these parasites, only Ph. praeputialis was collected from the stomach, all other helminths were collected from the small intestine.
ConclusionThe results demonstrate a high infection rate of stray cats with zoonotic helminths. The presence of zoonotic species in stray cats, particularly T. mystax, has public health importance.

BackgroundIn this study, some microsporidial and coccidian parasites were isolated from 103 domestic cats in the Meshkin Shahr area, northwestern Iran during the Jun 2014 to Jun 2015, and their genera were identified using parasitological methods with emphasis on their zoonotic importance.MethodsOne hundred and three fecal samples of domestic cats were collected and preserved in formalin (10%) and conserved in phosphate buffer saline solution, finally examined by microscopy after formalin-ether concentration and specific staining. Preservation in dichromate potassium (2.5%) was performed for all coccidian positive samples and then sporulated coccidian oocysts were investigated.ResultsThe detected parasites were Isospora spp. 6/103(5.8%). Microsporidian spores were identified in 46/103 (44.6%) of all samples post-stained by the aniline blue staining method.ConclusionMicrosporidial infections were more prevalent in domestic cats. Further studies are needed in the identification of microsporidial spores isolated from infected cats.Keywords: Intestinal protozoa, Cats, Iran}

BackgroundRodents play an important role as reservoir of some pathogens, and the host of some ectoparasites as well. These ectoparasites can transmit rodents pathogens to human or animals. The aim of this study was to assess the distribution and infestation load of ectoparasites on rodents in Meshkin-Shahr District, northwestern Iran.MethodRodents were captured using baited live traps in spring 2014 from Meshkin-Shahr District and were transferred to the laboratory for identification to the species level. Their ectoparasites were collected, mounted and identified.ResultsThree rodent species including Meriones persicus (74%), Mus musculus (16.9%) and Cricetulus migratorius (9%) were identified. Among all rodents, 185 specimens (90.69%) were infested with a total of 521 ectoparasites. Overall, 10 arthropods species were collected, including fleas (97.6%), one mite (1.6%) and one louse species (0.6%) as follows: Xenopsylla nubica, X. astia, X. buxtoni, X. cheopis, Nosopsyllus fasciatus, N. iranus, Ctenocephalides felis, Ctenophthalmus rettigismiti, Ornithonyssus sp and one species of genus Polyplax. The most prevalent ectoparasites species was X. nubica (89%).ConclusionNearly all rodent species were infested with Xenopsylla species. Monitoring of ectoparasites on infested rodents is very important for awareness and early warning towards control of arthropod-borne diseases.Keywords: Rodent, Ectoparasites, Iran}

BackgroundDirofilaria immitis is a common nematode of the cardiovascular system, which infects carnivores all over the world. The infection is prevalent in dogs, but in cats and human is rare. Dirofilariosis is transmitted by mosquitoes. Cats are accidental hosts and are naturally resistant to the infection, compared to the dogs. Mild infection can cause severe illness in cats and may lead to death, so it is clinically important to diagnose the disease.MethodsIn the present study, 103 stray cats were collected from Meshkin Shahr district, Aradabil Province, northwestern Iran that is an endemic area for canine dirofilariosis. Blood samples were prepared from the saphenous vein of each cat and were examined for the presence of microfilariae by the modified Knott test.ResultsA 2 yr old male cat (0.97%) was microfilaremic. The cat was subjected to necropsy and 4 adult D. immitis (2 male and 2 female worms) were found in the right ventricle of the heart. PCR was then carried out and D. immitis was confirmed.ConclusionCats and other carnivores in Meshkin Shahr district are at risk of infection due to the high activity of vectors in this climate and it is important to follow up the infection in this area.Keywords: Dirofilariosis, Cat, Microfilariae, Iran}
