What is the morphology of Proteus vulgaris?
Proteus Vulgaris is a rod shaped Gram-Negative chemoheterotrophic bacterium. The size of the individual cells varies from 0.4 to 0.6 micrometers by 1.2 to 2.5 micrometers. P. vulgaris possesses peritrichous flagella, making it actively motile.
What are the characteristics of Proteus?
Proteus species are gram-negative, rod-shaped, and facultatively anaerobic. The majority of strains are lactose negative with characteristic swarming motility that will become evident on agar plates.
What is the shape and arrangement of Proteus vulgaris?
Shape – Proteus Vulgaris is a short, straight rod shape (bacillus) bacterium. Size – The size of Proteus Vulgaris is about 1–3 µm × 0.5 µm (micrometer). Arrangement Of Cells – Pr. vulgaris is arranged singly, in pairs, or in short chains and sometimes in clusters.
What does the Proteus look like?
Proteus is a gram-negative, anaerobic bacterium of the Enterobacteriaceae family (Brooker 2008). Under the microscope it is rod shaped, motile (can move due to its flagella) and has a characteristic “swarming” ability that allows it to migrate across catheter surfaces (Armbruster 2013).

How do you identify Proteus vulgaris?
Proteus vulgaris is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter.
Is Proteus vulgaris aerobic or anaerobic?
Proteus vulgaris Proteus vulgaris is an facultative anaerobe, rod-shaped, Gram-negative bacterium in the Enterobacteriaceae family. It causes urinary tract and wound infections.
What does Proteus vulgaris smell like?
Some characteristics of a Proteus culture are swarming and an ammonia smell. The Proteus habitat is widely distributed in the environment. As an opportunistic human pathogen, Proteus is found in the human and animal gastrointestinal tract, skin, and oral mucosa, as well as in feces, soil, water, and plant.
Is Proteus vulgaris a coliform?
The genera Escherichia, Klebsiella, Enterobacter, Serratia, and Citrobacter (collectively called the coliform bacilli) and Proteus include overt and opportunistic pathogens responsible for a wide range of infections. Many species are members of the normal intestinal flora.
What is the significance of Proteus vulgaris?
Proteus vulgaris Proteus vulgaris is an facultative anaerobe, rod-shaped, Gram-negative bacterium in the Enterobacteriaceae family. It causes urinary tract and wound infections. In recent years, the resistances to many antibiotic classes (also beta-lactams) has significantly increased.
