| epidemiologic study of campylobacteriosis in iowa cattle and the possible role of unpasteurized milk as a vehicle of infection. | bile samples were collected from 477 iowa dairy cows and were cultured for thermophilic campylobacters. the prevalence of thermophilic campylobacters in the bile was 15.5%. campylobacter jejuni and c coli from dairy cattle, chickens, pigs, sheep, and human beings were serotyped to develop host-species profiles. human and cattle serologic profiles were the most similar, and human and chicken profiles shared several similarities. epidemiologic data from 168 human cases of campylobacteriosis indica ... | 1986 | 3954200 |
| emergence of a tetracycline-resistant campylobacter jejuni clone associated with outbreaks of ovine abortion in the united states. | campylobacter infection is one of the major causes of ovine abortions worldwide. historically, campylobacter fetus subsp. fetus was the major cause of campylobacter-associated abortion in sheep; however, campylobacter jejuni is increasingly associated with sheep abortions. we examined the species distribution, genotypes, and antimicrobial susceptibilities of abortion-associated campylobacter isolates obtained from multiple lambing seasons on different farms in iowa, idaho, south dakota, and cali ... | 2008 | 18322054 |
| antimicrobial resistance, virulence, and genotypic profile comparison of campylobacter jejuni and campylobacter coli isolated from humans and retail meats. | a total of 360 spatially and temporally related campylobacter isolates, including 168 from clinical human cases (campylobacter jejuni n = 148; campylobacter coli n = 20) and 192 from retail meats (c. jejuni n = 114; c. coli n = 78), were analyzed for antimicrobial susceptibilities, virulence, and genotypic profiles. ciprofloxacin-resistant c. jejuni was observed in 13.5% and 19% of the isolates from humans and retail chicken breasts, respectively. antimicrobial resistance to ciprofloxacin and er ... | 2010 | 20367499 |
| prevalence and antimicrobial resistance profile of campylobacter spp. isolated from conventional and antimicrobial-free swine production systems from different u.s. regions. | we conducted a study to compare the prevalence and antimicrobial resistance profile of campylobacter isolated from 34 farm-slaughter pair cohorts of pigs raised in conventional and antimicrobial-free (abf) production systems. isolates originated from four different states of two geographic regions (region 1--ohio and michigan; region 2--wisconsin and iowa). a total of 838 fecal and 1173 carcass samples were examined. campylobacter isolates were speciated using multiplex polymerase chain reaction ... | 2010 | 21133777 |
| occurrence and molecular analysis of campylobacter in wildlife on livestock farms. | wildlife harbor a variety of campylobacter spp. and may play a significant role in the transmission of campylobacter to livestock. although studies have been conducted on wildlife-associated campylobacter isolates from farms in other countries, there are little data available for livestock farms in the united states. in addition, the critical questions of whether wildlife harbor campylobacter that is pathogenic to ruminants and/or antibiotic-resistant campylobacter have yet to be addressed. we c ... | 2011 | 22266157 |
