The 'Redmite' in snakes carries which organism?

• A. Pasteurella
• B. Salmonella
• C. Staphylococcus aureus
• D. Aeromonas

Answer: (D)

Ectoparasites like red mites can act as vectors for bacteria that infect their hosts. These mites can harbor bacteria such as Aeromonas in their gut or on their mouthparts and pass them to snakes during feeding or contact. Aeromonas species are Gram-negative bacteria commonly found in freshwater environments and are known to cause infections in reptiles, which is why this organism is the one carried by the red mite. While Salmonella is a reptile-associated pathogen, the mite-to-snake transmission context here aligns more with Aeromonas. Pasteurella and Staphylococcus aureus are not typically linked to transmission by red mites in snakes.
