In ruminants, which serotype is considered clinically important?

• A. Dublin, Typhimurium, Newport
• B. Dublin only
• C. Typhimurium only
• D. Newport only

Answer: (A)

The serotypes that are most clinically important in ruminants are Dublin, Typhimurium, and Newport. Salmonella Dublin is especially relevant in cattle because it’s cattle-adapted and can cause severe disease in calves and adults, often leading to persistent carriage within herds. Salmonella Typhimurium has a broad host range and is a common cause of enteric disease in young ruminants, with occasional septicemia, making it a frequent concern in bovine herds. Salmonella Newport is another major cattle-associated serotype, prevalent in bovine populations and capable of causing both enteric and systemic illness, and it’s monitored because of its epidemiological significance and potential antimicrobial resistance. While many Salmonella serotypes exist, these three stand out as the most clinically impactful in ruminant species.
