Providencia rettgeri

Providencia rettgeri

Providencia rettgeri is a species of Gram-negative bacteria belonging to the genus Providencia. It is known for its role in human infections and its presence in various environments.

Characteristics

Providencia rettgeri is a rod-shaped, motile bacterium that is part of the family Morganellaceae. It is a facultative anaerobe, meaning it can survive in both aerobic and anaerobic environments. The bacterium is oxidase-negative and catalase-positive, which are important characteristics used in its identification.

Habitat

Providencia rettgeri is commonly found in soil, water, and sewage. It is also part of the normal intestinal flora of humans and animals. However, it can become pathogenic under certain conditions.

Pathogenicity

Providencia rettgeri is an opportunistic pathogen, primarily causing infections in immunocompromised individuals. It is associated with urinary tract infections, particularly in patients with long-term indwelling catheters. The bacterium can also cause wound infections, septicemia, and other healthcare-associated infections.

Antibiotic Resistance

Providencia rettgeri has been noted for its resistance to multiple antibiotics, which complicates treatment options. It often exhibits resistance to beta-lactam antibiotics and may produce extended-spectrum beta-lactamases (ESBLs), which confer resistance to a wide range of penicillins and cephalosporins.
