Low prevalence of antibodies against the zoonotic agents Brucella abortus,Leptospira spp., Streptococcus suis serotype II, Hantavirus, and lymphocytic choriomeningitis virus among veterinarians and pig farmers in the southern part of the Netherlands

Serum samples from 102 veterinarians and 191 pig farmers from the southern part of the Netherlands were investigated for antibodies against Brucella a bortus, Leptospira spp, Streptococcus suis serotype II, Hantavirus (HV), an d lymphocytic choriomeningitis virus (LCMV), All samples were collected in 1993 and stored until this study was performed. The prevalence of antibodie s against B. abortus in veterinarians (4.5%) was significantly higher (P=0. 01) than in pig farmers (0%), None of the veterinarians (0%) and only one p ig farmer (0.5%) had antibodies against Leptospira spp,, Furthermore, signi ficantly (P=0.015) more veterinarians (6%) than pig farmers (1%) had antibo dy titres against muramidase-released protein (MRP), a protein of pathogeni c S. suis serotype II strains. None of the veterinarians and a total of 3 ( 1.6%) pig farmers had antibody titres against HV. The prevalence of antibod ies against LCMV tended to be higher in pig farmers (2.6%) than in veterina rians (0%) (P=0.10), It can be concluded that the prevalence of antibodies against the investigated zoonotic agents in veterinarians and pig farmers i s low.
