Proteus vulgaris
the Indole-Positive Uropathogen While its cousin Proteus mirabilis gets most of the attention, Proteus vulgaris is a formidable opportunistic pathogen in its own right, armed with a powerful array of virulence factors and a significant intrinsic resistance profile. For any clinical lab, distinguishing these two indole-negative vs. indole-positive relatives is a critical step in guiding patient care. This comprehensive guide is an essential briefing for clinical microbiologists and infectious disease teams. We'll take you to the bench to explore the full laboratory profile, from its characteristic swarming motility and distinct odor to the key biochemical tests—indole, ODC, and maltose fermentation—that are essential for a definitive identification. Discover the pathogenesis of P. vulgaris, including its potent urease activity that contributes to urinary stone formation in complicated UTIs. Most importantly, we'll break down its intimidating antimicrobial resistance patterns, including intrinsic resistance to several key antibiotics, and compare Dutch (SWAB) and international guidelines to navigate the complex therapeutic landscape.
