Popis: | The seroprevalence and maternal antibody profiles to Newcastle disease virus infection of guinea fowls were studied using haemagglutination inhibition (HI) test, in Borno and Yobe States of Nigeria. Of 822 sera and 354 egg yolk extracts tested, 327 (39.8%) and 242 (68.4%) were positive for NDV antibodies respectively. The seroprevalence was significantly higher (P< 0.05) in the dry (47%) than in the rainy (32.8%) seasons. Maternal antibodies in egg yolk extract (sampled during the rainy season), were significantly (P< 0.05) higher (68.4%) than the seroprevalence. The frequency distribution of antibody titers were skewed with 79.8% and 63.2 % of sera and egg yolk respectively having reciprocal antibody titres ≤ 20. The geometric mean antibody titre was higher (P< 0.05) in the dry season (3.7±2.0) than in the rainy season (2.5 ±1.7). The geometric mean titre was also higher (P |
