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
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
fertility and viability rates of hydatid cysts in slaughtered animals in the mazandaran province, northern iran.the aim of this study was to determine the fertility and viability of hydatid cysts in slaughtered sheep and cattle. cysts were collected from the liver and lungs of 169 sheep and 171 cattle infected with echinococcus granulosus when slaughtered in industrial abattoir in sari, iran, 2007-2008. fertility was determined by the examination of cyst fluid for the presence of protoscoleces. the viability of the protoscoleces was assessed by staining with 0.1% aqueous eosin solution. the fertility rate ...200919455399
rostellar hook morphology of larval echinococcus granulosus isolates from the indian buffalo and iranian sheep, cattle and camel.isolates of echinococcus granulosus from the indian buffalo and iranian sheep, cattle and camels were characterized on the basis of rostellar hook morphology of the protoscolices. results obtained indicated phenotypic polymorphism among parasites isolated from different host species. isolates from buffalo are morphologically quite different from those of the more common sheep and cattle isolates and may represent a different strain, adapted to buffalo. in the sari region of northern iran, two mo ...201020815974
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
pattern of animal-related injuries in iran.animal related injuries as most common causes of human morbidity have different pattern by geographical zones. we aimed to explore the main descriptive epidemiology of animal-related injuries in both rural and urban areas in iran. between 2000 and 2004, we collected the data of all the cases of animal related trauma hospitalized for more than 24 hours in eight cities (tehran, mashhad, ahwaz, shiraz, tabriz, qom, kermanshah, and babol). further evaluations were conducted on 17753 eligible subject ...201121681704
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
seroepidemiology of sheep toxoplasmosis in babol northern iran 2004.this study is carried-out with the aim of determining the prevalence rate of toxoplasmosis in sheep at babol (bandpei part). in this study, 285 sheep of bandpei area in babol was selected. the samples studied with indirect immunofluorescence antibody. the results showed that 31.2% of sheep in this study were affected by toxoplasmosis. in positive cases, there was not any statistically significant difference between male and female sheep. the most positive cases observed by 1:200 titer. according ...200719070070
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
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
