Opis:: Zoonotic serotypes of Salmonella enterica subsp. enterica are an important biological factor that poses a threat to public health, and broilers are often asymptomatic carriers of these bacteria. The aim of this study was to analyze the prevalence of Salmonella spp. and Salmonella serotypes in broiler chicken flocks in northern Poland in 2014–2016. The study was conducted on commercial flocks monitored by the Institutes of Veterinary Hygiene in Gdańsk and Olsztyn in 2014–2016. A total of 4,331 samples were investigated. Identification of Salmonella spp. was performed by a culture-dependent method followed by biochemical and serological confirmation tests, in accordance with Polish Standards. The total percentage of infected flocks in northern Poland reached 1.57%. The prevalence of Salmonella spp. in broiler chickens decreased from 2.19% in 2014 to 1.22% in 2016. The percentage of flocks infected with S. Enteritidis and S. Typhimurium was 1.18% and 0.12%, respectively (S. Enteritidis and S. Typhimurium were detected in 1.29% of flocks). The most common serotypes that had not been covered by the control programme were S. Mbandaka (0.14%), S. Infantis (0.07%) and, sporadically, S. Kentucky and S. Anatum. The percentage of infected flocks was higher (by 0.26%) in the Pomeranian Region than in the Region of Warmia and Mazury, and it increased over the analyzed period – the highest number of positive samples were found in 2016 (2.04%). In the Region of Warmia and Mazury, the percentage of infected flocks was highest in 2014 (3.08%); in 2014–2016, the number of positive samples decreased steadily to reach 0.41% in 2016. In the analyzed regions, the incidence of human salmonellosis was correlated with the percentage of infected broiler flocks.

Trichomonas hominis
Opis:: The flagellate Trichomonas hominis is often identified in human diarrheic stools. Because of the fecal-oral transmission rout, infection with 7. hominis is more frequently reported in children than in adults. Although infections with the trichomonads in some world regions are as often as with Giardia, no prevention and optimal treatment are defined. The purpose of our in vitro studies was to examine susceptibility of T. hominis to a newly synthesized imidazole derivative — 1-metylo-2-(2,4-dinitrobenzylotio)-1H-imidazol — P27; in order to make a comparison between this new and previously known compounds, chlorhexidine and metronidazole were used. The protozoans derived from the diarrheic stool of adult patient were grown on the liquid Pahm medium and subcultured twice a week. Assays of trichomonad cultures were incubated with one of the following substances: chlorhexidine, metronidazole or P27. For each compound, two different concentrations were applied. After 24h exposition, an antitrichomonal effect of the above substances was assessed, namely a quantity of the surviving trichomonads was microscopically determined and compared with that observed in control cultures. The protozoans showed different susceptibility, depending on kind and concentration of tested compound. In comparison to the control cultures, the reduction in number of surviving protozoans appeared in the assays with metronidazole, chlorhexidine and P27 (to 63%, 52% and 8.7%, respectively). The highest in vitro susceptibility of 7. hominis was revealed to a new imidazole derivative P27. The obtained results allow us to suppose that the further studies in this field will be very helpful for explaining the mechanisms of the antitrichomonal activity of the tested compounds as well as for assessment of the influence of various abiotic factors.
