Sero-Epidemiology of Q-Fever in Poultry

Abstract

The sero-epidemiology of Q-fever was studied by capillary agglutination test at 25 poultry farms in the Nainital and Ajmer districts of Uttar Pradesh and Rajasthan. Of 589 birds tested, 78 (13.24%) had Q-fever agglutinins (CAT titers 1:8 to 1:64), involving 16 of the farms. There were more sero-reactors in Ajmer (17.56%) than in Nainital (3.35%). The sero-positive reactors were respectively 19.74% and 5.55% among the age groups above and below 6 months. The breed difference and comparatively high infection rates in poultry attendants of a Q-fever-positive farm are discussed.
