Proteus penneri ATCC 35198

Proteus penneri ATCC 35198 is a Gram-negative, rod-shaped bacterium that thrives in mesophilic temperatures, categorized as a facultative anaerobe. This microbe is typically found in various body sites across different species, notably within the gastrointestinal tracts of humans and animals, as well as in urinary tracts and wounds. Being a member of the Enterobacteriaceae family, it shares the common trait of being able to switch between aerobic and anaerobic respiration, allowing it to adapt to varying environmental conditions. As a Gram-negative organism, the cell wall structure of P. penneri consists of a thin peptidoglycan layer surrounded by an outer membrane, which contains lipopolysaccharides. This configuration contributes to its pathogenic potential, as it can evade the immune response and resist certain antibiotics. The rod-like shape facilitates mobility, enhanced by flagella that allow the microbe to navigate through viscous environments, such as mucus in the intestines or urinary tracts. P. penneri is classified as a chemoheterotroph, meaning it obtains its energy and carbon from organic compounds. This metabolic flexibility not only supports its growth in nutrient-rich environments but also allows it to contribute to various biochemical processes, including ammonia production during amino acid degradation. The presence of urease enables P. penneri to hydrolyze urea, which can contribute to urinary tract infections. In addition to its clinical significance, P. penneri is also involved in microbial ecology, playing a role in the gut microbiota of humans and animals, where it can influence digestion and nutrient absorption. Understanding this organism's behavior and characteristics is vital given its potential impact on human health, particularly in nosocomial infections and antibiotic resistance.
