The seroprevalence of ten zoonoses in two villages of Crete, Greece.

The seroprevalence and incidence of 10 zoonoses due to Rickettsia typhi, R. conorii, Coxiella burnetii, Burcella sp., Borrelia sp., Toxoplasma sp., Leishmania sp., Entamoeba histolytica, Echinococcus granulosus and Fasciola hepatica were studied in an animal husbandry and a farming village in Crete, Greece. The serum conversion incidence of each infectious agent was determined by testing 2 blood samples, collected in 1985 and in 1987. The surveillance was conducted using detailed transparent maps of the 2 villages studied, on which epidemiological data were interrelated to the results obtained from the serological tests. Thus the importance and spread of each infection were visualized. C. burnetii, Toxoplasma sp., R. conorii, and E. granulosus, were the most common infectious agents encountered during this study.
