status of haemaphysalis tick infestation in domestic ruminants in iran.the geographical distribution and ecological preferences of haemaphysalis in domestic animals in iran were studied 4 times a year from april 2003 to march 2005. a total of 1,622 ixodid tick specimens were collected from 3 different zones. among them, 108 (6.7%) haemaphysalis ticks, consisting of 6 species, were identified; h. punctata (3.4%), h. parva (0.5%), h. sulcata (0.6%), h. choldokovskyi (1.7%), h. concinna (0.06%) and haemaphysalis sp. (0.6%). h. punctata was the most abundant species, w ...200717570976
human and animal fascioliasis in mazandaran province, northern iran.the fascioliasis situation in humans and livestock of iranian mazandaran is analysed for the first time. coprological studies showed 7.3% and 25.4% global prevalences in sheep and cattle, respectively. studies in slaughterhouses indicate that sheep and cattle may be the main reservoir species, buffaloes may play local roles in the transmission, and goats and horses probably only participate sporadically. morphometric studies by computer image analysis showed that forms intermediate between fasci ...200415338292
isolation and molecular characterization of toxoplasma gondii strains from different hosts in iran.toxoplasma gondii is one of the most prevalent protozoan parasites in iran. this study was aimed to isolate t. gondii from a variety of hosts and to genetically analyze the parasite isolates. the prevalence of t. gondii in different animal hosts was assessed in two provinces of iran, tehran and mazandaran in the central and northern parts, respectively. the latex agglutination (la) test was carried out, and antibodies were found in 24 out of 105 sheep, 5 out of 35 goats, 23 out of 45 free-rangin ...200717333278
seroprevalence of toxoplasma gondii in cattle, sheep and goats slaughtered for food in mazandaran province, iran, during 2005.serum samples from 290 cattle, 400 goats and 588 sheep slaughtered for food in various areas of the mazandaran province, iran were tested for antibodies to toxoplasma gondii by the indirect immunofluorescence antibody test (ifat), from december 2004 to april 2005. antibodies to t. gondii were found in 30% (120/400) goats and 35% (206/588) sheep and 0% (0/290) cattle, at a dilution of 1:16 or more for goats and sheep and 1:128 or more for cattle. the highest titres observed in cattle, goats and s ...200716919980
a survey on hydatidosis in livestock in northern iran based on data collected from slaughterhouses from 2004 to have been collected from slaughterhouses in three provinces across the northern iran (gilan, mazandaran and golestan) from march 2004 to march 2008. these data were collected to evaluate the prevalence of hydatidosis in slaughtered cattle, sheep and goats. during the study, 3,347,797 animals were slaughtered. these included 621,686 cattle, 1,719,725 sheep and 1,006,386 goats. the prevalence of infection in cattle, sheep and goats was 12%, 14.6% and 10.1%, respectively. the association of co ...201121665368
identification of different theileria species (theileria lestoquardi, theileria ovis, and theileria annulata) in naturally infected sheep using nested pcr-rflp.ovine theileriosis is an important hemoprotozoal disease of sheep and goats in tropical and subtropical regions that leads to economic losses in these animals. a nested pcr-restriction fragment length polymorphism (rflp) was carried out to identification theileria species in sheep in some area in western half of iran (sari, rasht, urmia, ilam, and ahvaz). two hundred and fifty blood samples were taken from sheep during tick activating season (summer of 2008). microscopic examination revealed tha ...201020978792
