background: the purposes of the present study were morphometric characteri-zation of rostellar hooks of taenia multiceps and to investigate the association of hook length variation and the variability within two mitochondrial genes of sheep isolates of the parasite. methods: up to 4500 sheep brains were examined for the presence of c. cerebralis . biometric characters based on the larval rostel...

in this study a set of 10 polymorphic microsatellites (maf33, oarcp34, bm8125, maf214, maf70, dyms1, mcm527, oarjmp29, oarjmp58, bm1824) has been used to assess the distribution of genetic variation in six iranian sheep breeds (sanjabi, kabude shiraz, turki ghashghaii, lori, bakhtiyari and arabi). from each breed 45 sheep randomly were selected and their blood samples were collected individuall...

litter size is one of the most important economical traits in sheep breeding industry. in addition to minor genes, litter size is under the influence of major genes. bone morphogenetic protein 15 (bmp-15), a member of the transforming growth factor beta (tgf-ß) superfamily, which is specifically expressed in oocytes, plays a dramatic role in sheep prolificacy. reported mutations in this gene ca...

To study the structure of Iranian chemistry research, we identified 43 Iranian and international chemists who were highly cited in 7,682 Iranian chemistry publications (defined as an article with at least one Iranian author address) indexed in Science Citation Index (SciSearch) between 1990 and 2006, inclusive. We collected cocitation data for these authors from the entire SciSearch file (Dialo...

Background: To obtain update information on the prevalence of common food-borne parasitic diseases, this study designed to determine the prevalence of hydatidosis and liver flukes (Fasciola spp. and Dicrocoelium dendriticum) in the slaughtered cattle, sheep, and goats in Kermanshah, Iran from 2013 to 2016. Methods: In this four-year retrospective survey, information on the prevalence of hydati...

The objective of this experiment was to determine the effect of long-term low-dose administration of lead (Pb) on thyroid function in sheep. In this experiment 10 healthy Iranian male sheep, aged about oneyear- old were randomly allocated into two equal groups of control (n = 5) and experiment (n = 5). Both groups were kept under the same conditions of food and environment. The treatment group ...

five first-stage-larvae were removed by soft and pointed blottingpaper from the left eye of a woman and they were identified as oestrus ovis. she was infected in tehran and this is the first true case of ophrhalmomyiasis due to sheep nasal bot fly in iran. reports indicate that case of ophrhalmomyiasis are more frequent in iranian villages with different degree of .severity. methods for prevent...
