What species is known as a Gram Negative rod (Enteric)?

Serratia spp.
Corynebacterium spp.
Peptostreptococcus
Neisseria spp.

The correct answer is: Serratia spp.

Gram-negative rods that are often associated with the enteric (intestinal) tract include species such as Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Serratia spp. Among the options provided, only Serratia spp. fits this description. Serratia species are Gram-negative rods commonly found in the gastrointestinal tract and can cause infections if they enter other parts of the body. Therefore, the correct answer is A. Corynebacterium spp. are typically Gram-positive rods and are not specific to the enteric category. Peptostreptococcus species are Gram-positive cocci and are anaerobic bacteria commonly found in the oral cavity and gastrointestinal tract. Neisseria species are Gram-negative cocci, specifically diplococci, and are commonly found in the upper respiratory tract.
