Opis:: The presence of the flaA, cadF, cdtB and iam genes of Campylobacter spp. was determined with the PCR method. The materials to investigate were 56 C. jejuni and 23 C. coli strains isolated from clinical samples (children and domestic animals). It was found that all of the Campylobacter spp. isolates from children with diarrhoea and domestic animals had cadF gene, responsible for adherence. The flaA gene was present in all Campylobacter spp. isolates derived from children and cats. Occurrence of flaA gene was confirmed in 100% of C. jejuni strains obtained from dogs. The high prevalence of the cdtB gene associated with toxin production was observed in this study (100%-Campylobacter spp. isolates obtained from dogs and cats, 97.9%-Campylobacter spp. isolates from children). The isolates showed a wide variation for the presence of iam gene. The lowest prevalence (23.5%) was detected in Campylobacter spp. obtained from dogs. The highest rates of iam detection (91.6%) were revealed in C. coli isolates from children.

Opis:: Celem prezentowanych badań była kontrola wpływu niskich temperatur 4˚C na częstotliwość występowania bakterii Campylobacter coli na mięsie drobiowym. Próbki mięsa drobiowego (n=300) były pobierane losowo z wybranych ubojni. Identyfikacji C. coli dokonano przy zastosowaniu testu Api Camy i reakcji PCR. Stwierdzono, że schładzanie spowodowało obniżenie występowania C. coli w surowym mięsie drobiowym o 81,8%. Podsumowując można stwierdzić, że chłodzenie mięsa nie daje gwarancji całkowitej eliminacji bakterii Campylobacter coli.
The aim of this study was to check the influence of low temperatures 4° C on the frequency of occurrence of these bacteria in poultry meat. Samples of poultry meat (n = 300) were collected randomly from selected slaughterhouses. Identification of C. coli was performed using an API test and PCR reaction. It was found that the chilling effect of reducing the occurrence of C. coli in raw poultry meat by 81.8%. In summary it can be said that the chilling of meat does not guarantee the total elimination of Campylobacter coli.

Opis:: The intracellular survival of Campylobacter has been described within epithelial cells as well as in macrophages in vitro. The goal of this study was to estimate the viability of the genetically diverse C. jejuni and C. coli strains in the macrophage J774 cell line. Strains selected for analysis differed with regard to the occurrence of genes encoding specific virulence factors. The present work indicates that was no correlation between the source of isolates and relative intracellular survival.

Opis:: Slurry, due to high microbiological contamination, requires hygienization before spreading. The agricultural usage of treated slurry has to guarantee biosafety. Therefore, constant monitoring of the slurry treatment process should be conducted. The use of Filter-Sandwich carriers seems to be a prospective solution. The aim of the research was to test whether Filter-Sandwich carriers influence the survivability of microorganisms during the slurry hygienization process and hence, whether they are safe for the environment. Raw cattle and swine slurry with different dry matter content was the research material. Salmonella Senftenberg W775 rods were introduced directly into the slurry and into the carriers placed in the liquid excrements stored at 4 and 20 °C, and underwent anaerobic digestion at 35 °C. The number of tested bacteria obtained from the slurry and carriers was determined using the MPN method with proper microbiological media. The values of physicochemical parameters of the raw and treated slurry were determined, both for the carriers and for slurry only. Biosafety control was also conducted for the carriers in slurry containers. The differences in the theoretical survivability between Salmonella Senftenberg W775 re-isolated from the slurry and the carriers, and in the values of the selected physicochemical parameters obtained at the end of the process, were not statistically significant. The re-contamination of the sterile slurry caused by the bacteria in the carrier was not observed after placement of the carrier with inoculated material. The conducted research proves the usefulness of Filter-Sandwich carriers for continuous hygienization monitoring of the slurry treatment process. This refers not only to the semi-technical scale, but also to the full-scale process.
