Abstract

Serological examinations were carried out for Listeria monocytogenes antibodies in 1000 cattle serum of the county of Ribeirão Preto, in the state of São Paulo, Brazil. The serum assay was carried out by serum agglutination test in tubes with somatic antigens from serotypes L 1, L2, L3, L4a and L4b. It was considered to be reagent all sera reacting in a titer of 1:20 being positive only the sera with 1:320 or above. According to this criteria 193 (19,3%) serum samples were positive for the serotypes L1, L2, and L4b. The serotype L4b was the more frequent. All 16 positive serum and 32 of the 193 reacting serum from agglutination reaction were submit to the complement fixation test. It was found that high titer in complement fixation test corresponded to high titer observed in the serum agglutination reaction.
