pathogenicity of campylobacter jejuni for turkeys and chickens.a campylobacter jejuni isolate obtained from a turkey liver, designated c101, and a c. jejuni isolate obtained from the feces of a chicken, designated c111, were used to inoculate their respective hosts. isolate c101 depressed weight gain by 20% when inoculated into newly hatched poults or 4-day-old poults. it also caused death, hepatic necrosis, and generalized hemorrhages in turkey embryos. the chicken-derived isolate, c111, did not reduce weight gain in newly hatched chicks, but it did induce ...19921627109
rotaviruses in infants with diarrhea studied by viral rna electrophoresis in ankara, turkey.incidence of rotavirus in children under 2 years of age, admitted to 2 children's hospitals i n ankara, turkey, from july 1984-june 1985 was measured using viral rna electrophoresis in agarose gels. 375 children were selected at random from over 14,000 diarrhea admissions, and their stool specimens taken on admission were compared to those of 333 children without diarrhea. 61 (16.3%) of the diarrhea cases had detectable rotavirus, compared to 0% in controls. bacteriologic tests for salmonella ...19872851886

evaluation of transport and storage techniques for isolation of campylobacter fetus subsp. jejuni from turkey cecal specimens.immediate culturing of fecal specimens is not always possible, and appropriate methods for transport and storage of campylobacter fetus subsp. jejuni specimens have not been fully evaluated. using nine techniques, we studied the survival of c. fetus subsp. jejuni in cecal specimens from infected turkeys. the organisms survived in specimens held without transport medium for 3 to 15 days (median, 9 days) at 4 degrees c, and 2 to 9 days (median, 4 days) at 25 degrees c. only 20% of specimens frozen ...19817016895
dna diversity among isolates of campylobacter jejuni detected by pcr-based rapd fingerprinting.a pcr-based randomly amplified polymorphic dna method was used to amplify campylobacter jejuni dna using a single oligonucleotide primer derived from either a homologous source or from mycoplasma gallisepticum. the method was able to detect the heterogeneity of amplified dna from human, chicken and turkey sources and can be used as a tool to study the epidemiology of campylobacter jejuni infection.19957571378

campylobacter infection of commercial poultry.campylobacter jejuni, a widespread food-borne pathogen is responsible for enteritis in the populations of both industrialised and developing nations and is acquired by consumption of contaminated water, milk and food products. contaminated poultry meat is regarded as an important source of campylobacteriosis, with both commercial broiler and turkey growing flocks infected at two to three weeks of age by direct and indirect horizontal exposure. non-chlorinated water is regarded as a vehicle of in ...200010935269
ribotyping characterisation of campylobacter isolates randomly collected from different sources in this study the potential for using the automated psti ribotyping as a primary library typing method to survey campylobacter and for identification of two thermophilic campylobacter jejuni and campylobacter coli species was evaluated. a total of 158 isolates randomly collected in italy from different sources were analyzed. a large percentage of chicken (28%), turkey (27%) and turkey meat (25%) isolates shared their ribotyping profiles (ribotypes) with those of humans, whereas the swine isolate ...200314522511
quinolone-resistant campylobacter infections: risk factors and clinical consequences.we integrated data on quinolone and macrolide susceptibility patterns with epidemiologic and typing data from campylobacter jejuni and c. coli infections in two danish counties. the mean duration of illness was longer for 86 patients with quinolone-resistant c. jejuni infections (median 13.2 days) than for 381 patients with quinolone-sensitive c. jejuni infections (median 10.3 days, p = 0.001). foreign travel, eating fresh poultry other than chicken and turkey, and swimming were associated with ...200415207057
occurrence of campylobacter in retail foods in ireland.a surveillance study was carried out to determine the prevalence of campylobacter in a range of retail foods purchased in three irish cities over a 20-month period between march 2001 and october 2002. in total 2391 food samples were analysed during this period. campylobacter was isolated from 444 raw chicken (49.9%), 33 turkey (37.5%) and 11 duck samples (45.8%). lower isolation rates of 7/221 (3.2%), 10/197 (5.1%) and 31/262 (11.8%) were observed for raw beef, pork and lamb, respectively. one s ...200415282123

antimicrobial resistance among campylobacter jejuni isolated from raw poultry meat at retail level in denmark.campylobacter jejuni isolated from raw poultry meat collected at retail shops in denmark in the period 1996-2003 were tested for susceptibility to seven antimicrobial agents. the food samples consisted of raw chicken meat and other raw poultry meat of domestic or imported origin. the highest levels of resistance among c. jejuni were observed for tetracycline, nalidixic acid and ciprofloxacin, whereas macrolide resistance was rarely detected. c. jejuni originating from other poultry meat (mainly ...200616410028
bacteriocins reduce campylobacter colonization and alter gut morphology in turkey poults.campylobacter is a leading cause of food-borne illness in the united states. recent evidence has demonstrated that bacteriocins produced by bacillus circulans and paenibacillus polymyxa reduce cecal campylobacter colonization in broiler chickens infected with campylobacter jejuni. as campylobacter coli is the most prevalent campylobacter isolate recovered in turkeys, the objectives of the present study were to evaluate the efficacy of these bacteriocins against c. coli colonization and their inf ...200616977842
