Abstract


Campylobacter spp., belongs to the group of thermo-tolerant bacteria, and is the most frequent cause of gastrointestinal diseases in humans following consumption of poorly cooked chicken meat. The aim of our study was to test the common methodology for isolation of Campylobacter jejuni species from cloaca and cecum content of chicken broilers breed in intensive systems in Western part of Romania. The experiments were conducted during July –September 2013. As biological material we used chicken broilers from 6 intensive breeding facilities from the West part of Romania, from which cloaca swabs and cecum content were recovered as samples. Bacteria isolation was performed by inseminating Petri dish with Muller Hinton Agar media, after bacterial growth, they were subculture on Muller-Hinton Agar with Skirrow. The bacteria were tested by Gram staining and Oxidase test. Bacterial growth was detected from all samples when grown on Mueller-Hinton Agar, but when the bacteria was passed on Muller Hinton Agar with selective supplement (Skirrow) 27 out of 36 samples remained positive (75,0%). With respect to the sample origin 13 (72.2%) samples from cloaca swab and 14 (77.7%) from cecum content grown on campylobacter selective media. All samples from Muller-Hinton supplemented with Skirrow tested negative for Gram staining and positive for oxidase test. We have successfully isolated Campylobacter spp., strains from farms and private producers in the western part of Romania.
