Final answer:
Corynebacterium pyogenes and Sperophorus necrophorus are bacterial pathogens causing liver abscesses in cattle, impacting the health of the animal and potentially affecting the quality of beef products.
Step-by-step explanation:
Corynebacterium pyogenes and Sperophorus necrophorus can cause infections in cattle that lead to liver abscesses. They are both types of bacteria that contribute to the health issues in beef cattle. These organisms are not related to marbling, tenderization, or spoilage of meat. Instead, they are known pathogens that can affect animal health and, as a result, can impact the quality and safety of beef products if animals are slaughtered without proper diagnosis and treatment.
Corynebacterium pyogenes is mainly associated with liver abscesses and can cause severe infections in cattle, while Sperophorus necrophorus, more commonly known as Fusobacterium necrophorum, is also recognized for its role in liver abscesses as well as other conditions like foot rot and ruminal disorders.
