As the result of the prospective examination of 863 pregnant women in urban and rural consultation clinics for women in Daghestan, a high proportion of them were found to be infected with toxoplasmosis (25.5%), brucellosis (1.85%) and listeriosis (12.2%). The data on the contamination of 1325 women with aggravated obstetric history were confidently higher, constituting 52.0%, 3.3% and 22.2% respectively. The results of the examination of women working on live-stock farms (226 women) and poultry farms (106 women) demonstrated a significantly high frequency of contamination with the above-mentioned zoonotic infections. The data thus obtained were indicative of the necessity of organizing epidemiological surveillance on these infections; for their diagnostics a complex of laboratory methods could be used, though the effectiveness of these methods was different in different nosological forms.
