Potential virulence factors of Proteus bacilli.

Comparison of virulence genes in Proteus species isolated from human and pet turtle

The current study was aimed to investigate the prevalence of ureC, rsbA, zapA and mrpA virulence genes using polymerase chain reaction (PCR) in Proteus spp. isolated from 5 commercially popular species of pet turtles and comparison of the mrpA gene sequences of Proteus mirabilis isolates with human clinical isolates. A total of 24 isolates in pet turtles were identified, comprised of P. mirabil...

Swarming growth and resistance of Proteus penneri and Proteus vulgaris strains to normal human serum.

BACKGROUND Proteus sp. strains isolated from patients with urinary tract infection (UTI) are often insensitive to the bactericidal action of normal human serum (NHS) which poses a clinical problem. The swarming phenomenon is an especially important factor in cases of UTIs gained through the ascending route. Both these virulence factors are connected with the cell surface components of bacteria,...

Virulence Factors Of Uropathogenic Proteus Mirabilis - A Mini Review

Proteus mirabilis is a common causative agent of the urinary tract. This microorganism expresses several virulence factors. In uropathogenesis processes P. mirabilis can expresses adhesins, flagella, toxins, enzymes, quorum sensing and immune evasion factors. This review describes some aspects of virulence factors of uropathogenic P. mirabilis.

The Ciprofloxacin Impact on Biofilm Formation by Proteus Mirabilis and P. Vulgaris Strains

BACKGROUND Proteus spp. bacilli belong to opportunistic human pathogens, which are primarily responsible for urinary tract and wound infections. An important virulence factor is their ability to form biofilms that greatly reduce the effectiveness of antibiotics in the site of infection. OBJECTIVES The aim of this study was to determine the value of the minimum concentration of ciprofloxacin t...
