VYLETELOVA-KLIMESOVA, M., O. HANUS, A. DUFEK, I. NEMECKOVA, J. HORACEK, A. PONIZIL and L. NEJESCHLEBOVA , 2014. Staphylococcus aureus and other pathogens in relation to breed of cattle and somatic cell count. Bulg. J. Agric. Sci., 20: 1477-1482
Influence of breed on somatic cell count (SCC) and occurrence of particular species was evaluated. The samples were collected from farms with Holstein (H; 10 farms - 365 cows) breeding and from farms with Czech Fleckvieh (CF; 2 farms – 67 cows). The obtained dataset was statisticaly evaluated by analysis of variance. The occurrence of pathogens was compared between H and CF. The relationship between SCC and incidence of pathogens was determined as well. It is evident that more positive cows were in breed H compared to CF (H 41.6%; CF 26.9%). The most frequent pathogens in H breed were S. aureus(13.7%), S. uberis (9.6%), S. haemolyticus (8.5%), S. agalactiae (6.9%), E. faecalis (2.5%) and E. faecium (0.8%), while only S. uberis (19.4%), S. haemolyticus (6%) and S. aureus (1.5%) were found in CF. SCC results showed the higher SCC in H breed in case of both negative and positive cows as well and significant impact of breed on logSCC (F = 6.4, P = 0.012). The significant effects of bacterial species were confirmed (F = 13.6, P < 0.001). Multiple comparison among groups of bacterial species showed significant differences between negative and S. aureus, S. agalactiae, S. uberis (P = 0.012, P < 0.001, P < 0.001). Differences between negative and other pathogens were not signifiant.
