Proteus species (Proteus spp.)

Target
Proteus spp.
Molecular classification
Bacteria, Gram-negative bacteria, Enterobacteriaceae
01

Overview

Proteus species are Gram-negative, rod-shaped bacteria known for their swarming motility and role as opportunistic pathogens. Key characteristics include urease production, H₂S production, and lactose-negative status on MacConkey agar. They are commonly found in the environment and as part of the intestinal flora. Pathogenicity is mainly associated with UTIs, wound infections, and septicemia. Virulence factors include urease, which leads to kidney stone formation, and swarming motility, which aids in colonization. Notable species include *Proteus mirabilis* and *Proteus vulgaris*.
