Among the listed zoonotic diseases in rodents, which is a viral agent?

Explanation:
The important distinction here is that the correct option identifies a virus, not a bacterium. Lymphocytic choriomeningitis virus is an arenavirus transmitted primarily by house mice and can infect humans through inhalation of rodent excreta or contact with contaminated materials, causing fever, meningitis-like illness, and potential congenital infection. The other listed agents are bacteria—Staphylococcus aureus, Streptococcus species, and Pasteurella species—which can cause zoonotic infections but are not viruses.
