What could be a zoonotic concern when handling fish infected with Streptococcus?

When considering zoonotic concerns associated with handling fish infected with Streptococcus, the option highlighting meningoencephalitis is particularly relevant. Streptococcus species are known to have the potential to cause infections that may affect humans, particularly in immunocompromised individuals. While meningoencephalitis is less common, it can occur in those who have significant exposure or underlying vulnerabilities, particularly from certain strains of Streptococcus that have been associated with severe infections.

Skin infections can also occur in individuals who handle infected fish; however, they are generally more local and manageable compared to the systemic implications of a condition like meningoencephalitis. In terms of systemic inflammatory response, while it is a serious condition, it is typically a reaction to severe systemic infections rather than a direct zoonotic disease that can be specifically attributed to fish handling. Reduced appetite does not pertain as a zoonotic concern from infected fish, focusing instead on the clinical signs exhibited by the fish themselves. Hence, meningoencephalitis stands out as a serious zoonotic potential linked with handling infected fish, which emphasizes the significance of proper handling procedures and awareness of zoonotic risks in aquaculture practices.
