https://www.selleckchem.com/products/dtag-13.html The aim of this study was to investigate the frequency of Campylobacter species, to detect the antibiotic resistance profiles and the virulence genes and to determine the clonal proximity of the isolates in the samples of cutting board, slaughterhouse waste water, wall, knife and carcass from three different slaughterhouses in Kayseri region. For this purpose, a total of 150 samples, 10 of each from knife, wall, cutting board, carcass smear sample and slaughterhouse wastewater were collected from each of the three types of slaughterhouses in 2018 in Kayseri. For the isolation of the Campylobacter species, following preenrichment, the suspensions were inoculated onto modified charcoal cefoperazone desoxycholate (CCD) agar and were incubated at 37°C under microaerophilic condition for 48-72 hours. Suspicious colonies with gray-white color were recovered and subjected to phenotypical (Gram staining, oxidase, catalase test, and motion test) tests. Multiplex polymerase chain reaction (mPCR) was used for the molecuof the cdtC gene. The cdtA, cdtB, ceuE and cadF genes were found to be positive in all C.jejuni isolates. All isolates analyzed in the study demonstrated different ERIC-PCR profiles. In conclusion, it was shown that Campylobacter strains isolated from slaughterhouses were resistant to the most of the current antibiotics. Moreover, the presence of highly virulent Campylobacters in the slaughterhouse environment threatens public health due to the risk of contamination of the humans via carcasses and foods. Therefore, it is recommended that strict hygiene rules should be followed to reduce Campylobacter species contamination in slaughterhouses.Francisella tularensis is a gram-negative, coccobasillus, facultative intracellular bacteria and causes a zoonotic disease, tularemia in humans. F.tularensis has four subspecies, which have different virulences for humans as F.tularensis subsp. tularensis, F.tularensis subsp.
