| occurrence of colonization factor antigens i & ii in enterotoxigenic escherichia coli associated diarrhoea in iran & correlation with severity of disease. | the occurrence of colonization factor antigens i and ii (cfa/i and ii) and type 1 somatic pili was investigated in 197 enterotoxigenic esch. coli (etec) isolated from 197 patients of diarrhoea (aged under 3 yr) during february 1985 to march 1986 in tehran, iran. among etec strains, 154 strains were heat-stable enterotoxin (st) producers, 27 strains were heat-labile enterotoxin (lt) producers, and 16 strains produced both toxins. sixty five (33%) strains showed mannose-resistant haemagglutination ... | 1992 | 1354654 |
| indication of the presence of two distinct strains of echinococcus granulosus in iran by mitochondrial dna markers. | sixteen isolates of echinococcus granulosus, collected from iranian patients at surgery, and from domestic animals, including sheep, goats, cattle, and camels at slaughterhouses in tehran and central and southern iran were analyzed for dna nucleotide and predicted amino acid sequence variation within regions of the mitochondrial cytochrome c oxidase i (coi) and nadh dehydrogenase subunit i (ndi) genes. a polymerase chain reaction-restriction fragment length polymorphism method, based on the dna ... | 1998 | 9684648 |
| an abattoir survey on the frequency of fatty liver syndrome in dairy cows from the suburbs of tehran. | one hundred and six holstein and holstein x native cows were inspected before and after slaughter, and liver samples were taken. the fat content of all the liver samples was estimated by an extraction method (soxhlet). the livers of 29 cows (27%) were classified as fatty. seventeen of the animals were newly calved, 47 were non-pregnant, 33 were pregnant and 9 were dry, the median values for the fat content of their livers being 60.6, 34.4, 34.7 and 33.8 mg/g, respectively. the median concentrati ... | 2001 | 11234188 |

| serum antibodies to the major proteins found in cow's milk of iranian patients with type 1 diabetes mellitus. | the purpose of this study was to assess the humoral immune response to cow's milk proteins in iranian children with type 1 diabetes mellitus (t1dm). eighty children aged 4-17 yr with t1dm from two centres in iran (the iranian association of diabetes in tehran and center for diabetes research in hamedan), 37 apparently healthy siblings of diabetic patients (related controls), 82 apparently healthy age- and sex- matched controls (unrelated controls), and 32 patients aged 11-15 yr with auto-immune ... | 2004 | 15244098 |
| prevalence and antimicrobial resistance of campylobacter isolated from retail raw chicken and beef meat, tehran, iran. | campylobacter spp. is a leading cause of human diarrhea. the common source of infection is contaminated food, particularly poultry. the veterinary use of antimicrobial drugs has been suggested to be largely responsible for resistance in human isolates of this zoonotic pathogen. from april to october 2004, 241 samples of chicken and beef meat for sale in retail outlets in tehran (iran) were analyzed for the presence of campylobacter. totally, 88 (36.5%) campylobacter strains were isolated. campyl ... | 2006 | 16481059 |
| serologic study of anti-neospora caninum antibodies in household dogs and dogs living in dairy and beef cattle farms in tehran, iran. | a few studies have been done on the seroepidemiology of anti-neospora caninum antibodies in dairy and beef cattle farms in iran, which suggested the presence of n. caninum in these areas, but there is no published information directed on the presence or epidemiology of this organism in the dogs in iran. to investigate anti-n. caninum antibodies in household dogs and dogs living in cattle farms, 100 blood samples were collected: 50 from dogs living in dairy and beef cattle farms and 50 from house ... | 2007 | 17120042 |
| seasonal study of aflatoxin m1 contamination in milk in five regions in iran. | between april 2003 and february 2004, 98 samples of raw milk were obtained from milk tanks in one dairy plant in each of five regions in iran. these were chosen with mean distances apart of 400 km, whereby they have different ecologies (temperature, relative humidity, etc.) and different agricultural products were used for animal feeding. samples (24-25 per season) were laboratory heat treated and were analyzed for aflatoxin m1 with a validated high performance liquid chromatography (hplc) syste ... | 2007 | 17391793 |
| serological survey of antibodies against bvd virus in camels (camelus dromedarius) in iran. | this serological survey was carried out to detect antibodies in dromedary camels against bvd virus in iran. a total of 137 serum samples, were collected from camels at khorein abattoir in suburbs of tehran and examined for bvdv, using the serum neutralization test (snt). twenty seven of the 137 camels (19.7%) were positive for bvdv antibodies. it was found that the rate of seropositive camels in iran is substantially higher compared to figures published in most other countries. this study indica ... | 2010 | 19701796 |
| risk factors for abortion in dairy cows from commercial holstein dairy herds in the tehran region. | in last decade, pregnancy loss in dairy cattle has had an upward trend bringing difficulties for breeders: the annual cost is estimated around 396 billion rials (i.e. around 40 million us$) for the iranian dairy industry. the present study was conducted to determine the influence of maternal factors on abortion and to predict the probability of abortion as well as the effect of these factors on the fetal lifetime in holstein dairy cattle. data from 44,629 established pregnancies that included 14 ... | 2010 | 20598387 |
| 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 |
| genetic diversity of bovine neospora caninum determined by microsatellite markers. | neospora caninum is one of the most significant parasitic organisms causing bovine abortion worldwide. despite the economic impact of this infection, relatively little is known about the genetic diversity of this parasite. in this study, using nc5 and its1 nested pcr, n. caninum has been detected in 12 brain samples of aborted fetuses from 298 seropositive dairy cattle collected from four different regions in tehran, iran. these specimen (nc-iran) were genotyped in multilocus using 9 different m ... | 2015 | 25988829 |
| 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 ... | 2011 | 21681704 |
