The subject of the study was bacterial examination of the digestive track of laying hens. In the work two groups of laying hens were examined. In the first group was the one in which, after the clinical examination presence of diarrhoea was stated, and in the second group were three examples where such diagnostical symptoms were not found. The aim of the work was to try to isolate and identify Campylobacter in the digestive track of the laying hens, and to see if there are some differences in their presence and in their kinds in the two above mentioned groups of laying hens. Altogether 60 cloacal smears were examined (36 from the first group and 24 from the second). Presence of the Campylobacter kind in the first group was 88.88% or 32 positive hens, and in the second group were 33.33% or 8 positive hens. In the first group of the laying hens in 32 positive hens Campylobacter jejuni subsp. jejuni was isolated in 32 cases (100%) and in one case Campylobacter coli as a mixed isolate with Campylobacter jejuni subsp. jejuni. In the second group of the analyzed laying hens out of 8 known cases all 8 were isolated by Campylobacter coli. The results point to big presence of Campylobacter types in the sick laying hens and to the presence of different kinds of diarrhoea what certainly has to be investigated.
