Résumé
Septic arthritis often occurs in young calves when the passive transfer of maternal immunoglobulins has failed, which results in hypogammaglobulinaemia in the calf. Another important cause is suboptimal herd health management which often leads to general health impairment and, subsequently, to septic arthritis. A dairy farmer consulted the Herd Health Service of the University Clinic reporting general herd health impairment, a high incidence of respiratory diseases, unsatisfactory weight gain and arthritis in calves, as well as mastitis and high milk cell counts. Clinical examinations were performed, and diagnostic measures were taken. A transtracheal lavage (TTL) was performed, and synovial swab samples were taken from the carpal joint and the subcutaneous tarsal bursae of two calves. Microbiological examinations of synovial swabs revealed co-infections of Trueperella pyogenes and Helcococcus ovis in one calf and Helcococcus ovis in pure culture in the other. The TTLs confirmed the presence of Mycoplasma spp. associated with respiratory diseases. Helcococcus ovis is currently regarded as a co-infective bacterial agent. However, it seems to play a significant role as the primary pathogen in this case.

BACKGROUND
Septic arthritis often occurs in young calves when the passive transfer of maternal immunoglobulins has failed, which results in hypogammaglobulinaemia in the calf.

CASE PRESENTATION
METHODS
A dairy farmer consulted the Herd Health Service of the University Clinic reporting general herd health impairment, a high incidence of respiratory diseases, unsatisfactory weight gain and arthritis in calves, as well as mastitis and high milk cell counts. Clinical examinations were performed, and diagnostic measures were taken. A transtracheal lavage (TTL) was performed, and synovial swab samples were taken from the carpal joint and the subcutaneous tarsal bursae of two calves. Microbiological examinations of synovial swabs revealed co-infections of Trueperella pyogenes and Helcococcus ovis in one calf and Helcococcus ovis in pure culture in the other. The TTLs confirmed the presence of Mycoplasma spp. associated with respiratory diseases.
CONCLUSIONS
CONCLUSIONS
Helcococcus ovis is currently regarded as a co-infective bacterial agent. However, it seems to play a significant role as the primary pathogen in this case.
