Clostridium perfringens in Calves

What is Clostridium perfringens?

Clostridium perfringens is a Gram-positive, spore-forming, toxin-producing rod-shaped bacterium that is classified into several toxin types (including A, B, C, and E). Type A is a component of the calf’s normal intestinal flora and can also be detected in the feces of healthy animals. Under favorable conditions, individual strains can cause disease through necrotizing toxins.

Enterotoxemia in Calves

The pathogen is ubiquitous in the environment and the intestine. The clinical disease, which manifests as enterotoxemia, occurs sporadically and occasionally as a herd outbreak. It frequently affects healthy calves that are only a few days old, have a good appetite, and have ample access to milk.

Symptoms and Course

Characteristic features include hyperacute hemorrhagic abomasitis and enteritis with acute onset of apathy, weakness, bloody diarrhea, and abdominal pain. The course is rapid and often fatal within a few hours, frequently before treatment can take effect.

Diagnosis and Classification of Findings

Due to the hyperacute course and overlap with other causes of diarrhea, classification within the diarrhea spectrum is important. Since Clostridium perfringens is also present in clinically healthy animals, a positive test result must always be evaluated within the clinical context and in conjunction with other detected pathogens.

Clostridium Rapid Test in the Barn

The Fassisi® BoDia Plus and Fassisi® BoDia Advanced MPX tests detect Clostridium perfringens alongside other calf diarrhea pathogens (rotavirus, bovine coronavirus, E. coli K99/F5, Cryptosporidium parvum, and—in the case of BoDia Advanced MPX—Giardia as well) in calf feces. This allows for the differentiation between single and mixed infections from a single sample.
