| prevalence and molecular characterization of bovine cryptosporidium in qazvin province, iran. | the aim of this study was to determine the prevalence, variability with host age, and the genotypes of species of cryptosporidium in cattle from 15 dairy farms in qazvin province, iran. fecal samples, collected from 272 cattle during may 2006 to december 2007, were characterized microscopically. oocysts from 51 positive samples were analyzed using pcr assay of 18s ssu rrna, restriction fragment length polymorphism (rflp) and sequencing. we identified 72.6% of the positive samples as cryptosporid ... | 2009 | 19091477 |
| the chehr abad "salt men" and the isotopic ecology of humans in ancient iran. | we have carried out isotopic analysis (δ(13)c and δ(15)n) on five salt-preserved bodies from the salt mine at chehr abad, iran, dating from the 4th c. bc through to the 4th c. ad. in an attempt to identify the geographical origins of these people, we have analyzed over a hundred archeological bone samples from various archeological sites in iran. from the faunal remains, we observe that the entire ecosystem appears to be enriched in (15)n, which we suggest is due to the semi-arid nature of the r ... | 2010 | 20949607 |
| species diversity and geographic distribution of hard ticks (acari: ixodoidea: ixodidae) infesting domestic ruminants, in qazvin province, iran. | this report presents the results of the first faunistic study of hard ticks in qazvin province of iran. the primary objective was to determine the species diversity and geographic distribution of hard ticks that parasitize domestic ruminants. information about the abiotic preferences of these species has been provided. a total of 286 cattle, 1,053 goats, and 2,050 sheep were examined in 13 villages in 28 flocks distributed throughout the studied areas. total direct body collections of ticks were ... | 2011 | 21805220 |
| aflatoxin m1 in raw milk in qazvin province, iran: a seasonal study. | occurrence of aflatoxin m1 (afm1) was determined in 254 samples of raw milk obtained from dairy cow farms of qazvin province, iran. aflatoxin m1 analysis was carried out by using the competitive enzyme-linked immunosorbent assay technique for screening and high-performance liquid chromatography with fluorescence detection for confirmatory purposes. the limit of detection and quantification of the confirmatory method were 0.003 and 0.01 µg/l, respectively. aflatoxin m1 was detected in 204 analyse ... | 2015 | 26000549 |
