To determine the seroprevalance of antibodies to L. monocytogenes in cattle in Bursa province of Turkey was aimed in this study. Two hundred nine, aged 1-5 years, healthy Holstein cattle were randomly selected from 6 different districts and after clinical examination blood samples were collected. The herd size (number of cattle in each herd) and the animals fed silage were recorded. Antibodies to L. monocytogenes were determined by agglutination test according to the method described by of Osebold et al. Hematological parameters (white blood cell count, circulating red blood cell count, hematocrit and differenciated cell counts) were analyzed. Antibodies to L. monocytogenes were found in 101 (48.3 %) of the 209 cattle tested. Of 209 cattle tested 54 (25.8%) had 1/50, 74 (35.4%) had 1/100, 23 (11.0%) had 1/200 and 4 had (1.9%) 1/400 agglutination titer whereas no agglutination was detected in 54 (24.88%) cattle. 53.7% (58/108) of female and 42.5% (43/101) of male cattle have been found to be seropositive. The seropositivity in silage fed cattle (57.5%, 92/160) was found statistically higher than cattle that were not feed silage (18.3%, 9/49) (p<0.001). The higher seropositivity (55.8%) was observed in cattle from large herd size (50 – 100 cattle). As a result, in this study seroprevalence of antibodies to Listeria monocytogenes in cattle in Bursa province of Turkey was found as 48.3 % and it was concluded that silage feeding is an important factor in the epidemiology of listeriosis. Larger and detailed prophylactic studies must be planned to control this zoonosis infection for animal and human health
