Trueperella pyogenes; a Cause of Spleen Multi Abscesses in Cattle

Background: Truperella pyogenes (T. pyogenes) is a gram-positive bacterium which can lead to visceral abscesses in cattle. The abscesses may be found in internal organs such as spleen, kidney, liver, lungs and skin. The aim of this study is to focus on spleen abscesses due to T. pyogenes. Methods: The whole spleen was sent to the laboratory and the causative agent was evaluated using isolation methods and biochemical tests based on the colonies. Results: The appearance of isolated colonies and the results of biochemical tests confirmed the presence of T. pyogenes in the spleen lesions. Conclusion: The current results identified T. pyogenes as the only isolated bacterium in a case of visceral abscess. This study emphasizes the necessity of implementing effective planes such as improving sanitation, reducing stressful conditions, feeding cattle by balanced diet, avoiding sudden changes in grain intake, and controlling other diseases to prevent the chronic economical losses of visceral infection with T. pyogenes.
