ABSTRACT
In cattle, Coxiella burnetii infections are generally asymptomatic but can also be associated with reproductive disorders. Metritis is considered as one of the symptoms of C. burnetii infections, but reliable information is lacking. Therefore, information on the presence of C. burnetii in the uterine content of cows with metritis is important to increase our knowledge on this pathogen. In this study, the uterine content of 45 dairy cows with metritis belonging to 12 herds was tested for C. burnetii with a real-time PCR assay. Only one uterine sample tested PCR (highly) positive, all other samples were PCR negative. The PCR positive cow tested also positive for antibodies. Three other cows from other herds tested antibody positive. The bulk milk (BM) samples of these 12 herds were tested by real-time PCR assay and antibody-ELISA. Six BM samples (50%) were positive in PCR and 10 (83%) were positive in ELISA. Culturing the uterus samples by bacteriology, the most frequently cultured bacteria were arcanobacterium (n=24), E. coli (n=16), other streptococci (n=10), Streptococcus uberis (n=8) and Streptococcus dysgalactiae (n=5). This study indicates that C. burnetii is not an important cause for metritis in dairy herds, although apparently C. burnetii was or had been present in most of these herds.
