Abstract

Epidemiological studies on caseous lymphadenitis were carried out in Poland in 1996 and 2002 among goat herds covered by a milk recording program. Between-herd seroprevalence was 13.2% in 1996 and increased to 62.5% in 2002. The average size of seropositive herds was statistically significantly higher than that of seronegative ones, however there was no statistically significant difference in the age between the herds. A statistically significant prevalence ratio (PR) was identified and relevant attributable risk for exposed animals (AR(exp)) was calculated for the following risk factors: presence of seropositive males in a herd (PR=8.350; AR(exp)=0.651), presence of superficial abscesses in animals (PR=6.142; AR(exp)=0.620), presence of respiratory signs (PR=2.900; AR(exp)=0.393), presence of animals in poor condition in a herd (PR=2.774; AR(exp)=0.390) and occurrence of reproductive failures in a herd (PR=1.798; AR(exp)=0.230). Purchase of animals from abroad, mastitis and husbandry conditions (housing system, grazing system, hygienic conditions) were not shown to be statistically significant risk factors.
