Tetracycline (tet) resistance in Campylobacter isolated from organically raised broilers was investigated in this study. Two hundred forty-five samples from an organic broiler farm were collected weekly from the first week to the end of the production cycle, and they were cultured for thermophilic Campylobacter. Tetracycline resistance of these Campylobacter isolates was identified by the agar ...

The prevalence of thermophilic Campylobacter spp. was investigated in cattle on Washington State farms. A total of 350 thermophilic Campylobacter isolates were isolated from 686 cattle sampled on 15 farms (eight dairies, two calf rearer farms, two feedlots, and three beef cow-calf ranches). Isolate species were identified with a combination of phenotypic tests, hipO colony blot hybridization, a...

AIMS To develop a real-time (rt) PCR for species differentiation of thermophilic Campylobacter and to develop a method for assessing co-colonization of pigs by Campylobacter spp. METHODS AND RESULTS The specificity of a developed 5' nuclease rt-PCR for species-specific identification of Campylobacter jejuni, Campylobacter coli, Campylobacter lari, Campylobacter upsaliensis and of a hipO gene ...

By comparing nucleic acid sequences determined for one of the most variable areas of 23S rRNA genes of 23 Campylobacter strains, we were able to identify regions specific for thermophilic Campylobacter strains. Oligonucleotide primers corresponding to these unique regions were synthesized and used in the polymerase chain reaction. One primer pair selectively detected all thermophilic Campylobac...

BACKGROUND/AIM In some clinical forms of human Campylobacter infections, such as prolonged diarrhea or associated with postinfections sequels, antibacterial treatment is necessary. The aim of the present study was to evaluate the antimicrobial susceptibility of thermophilic Campylobacter strains isolated from patients with diarrhea, as well as from patients with diarrhea followed by postinfecti...

Thermophilic Campylobacters are major causes of gastroenteritis in human. The main risk factor of infection is consumption of contaminated or by cross-contaminated poultry meat. In Côte d'Ivoire, gastroenteritis is usually observed but no case of human campylobacteriosis has been formally reported to date. The aims of this study were to determine prevalence and antimicrobial resistance of Campy...

The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system i...

BACKGROUND: Campylobacteriosis is one of the most commonbacterial intestinal disorders of humans in many countries.A wide range of domestic and wild bird species have been identifiedas natural reservoirs. OBJECTIVES: The aim of this studywas to determine the Campylobacter spp from pet birds andscreen the determined Campylobacters for presence of virulencecytolethal distending toxin (cdt) genes....

To the Editor: Campylobacter spp. infection is the leading cause of bacterial enteritis worldwide. The epidemiology of Campylobacter infection in developing countries differs substantially from that in industrialized countries. In many studies from the United States and other industrialized countries, Campylobacter spp. are among the most common bacterial causes of diarrhea (1), with an inciden...

Seeking a sensitive protocol, culture-dependent methods were compared to detect thermophilic Campylobacter species in untreated urban effluents. We evaluated various combinations of selective media, with and without an enrichment steps, as well as an extra filtration step. Culture-independent real-time quantitative PCR was also included and all detected isolates underwent antimicrobial suscepti...
