Foetus: multifocal, small, pale hepatic nodules (granulomatous hepatitis).
Placenta: severe, diffuse placentitis.
Foetus: mild, granulomatous hepatitis.
Placenta: severe, diffuse, neutrophilic and necrotising placentitis with intracellular microorganisms.
Leptospirosis: Microscopic agglutination test for leptospirosis. Serum was collected from three does who recently aborted. The results are:.
The goats have been vaccinated for Leptospira interrogans serovar Pomona and Leptospira borgpetersenii serovar Hardjo, therefore the titre seen here is most likely due the vaccination antibodies.
Coxiellosis: Serum was collected from three does who recently aborted. The results for IFA IgG titre are:
The positive serology test indicates a previous or current infection. However, it does not indicate whether the infected doe is shedding the organisms. Shedding can also occur in the absence of a measurable antibody titre in up to 20% of infected animals. It is useful for screening herds but interpretation on individual level is difficult.
