the ability of subminimum inhibitory concentrations (sub-mics) of antibiotics to affect the virulence factors of bacteria may be an important criterion in selecting an antibiotic for therapy. proteus mirabilis is one of the most frequently seen pathogens in urinary tract infections. the aim of this study was to analyze the effects of some antibiotics on two important virulence factors of p. mir...

background proteus mirabilis is an important uropathogen that causes complicated urinary tract infection (uti) and induces diarrhea in infants. objectives this study aimed to investigate p. mirabilis infection in newly weaned infant rhesus monkeys (macaca mulatta) and ferrets (mustela putorius furo) with diarrhea. materials and methods stool samples were collected from 74 rhesus monkeys and 12 ...

Bacterial lipases from family I.1 and I.2 catalyze the hydrolysis of triacylglycerol between 25-45°C and are used extensively as biocatalysts. The lipase from Proteus mirabilis belongs to the Proteus/psychrophilic subfamily of lipase family I.1 and is a promising catalyst for biodiesel production because it can tolerate high amounts of water in the reaction. Here we present the crystal structur...

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...

Proteus mirabilis is a common causative agent of cystitis and pyelonephritis in patients with urinary catheters or structural abnormalities of the urinary tract. Several types of fimbriae, which are potentially involved in adhesion to the uroepithelium, can be expressed simultaneously by P. mirabilis: mannose-resistant/Proteus-like (MR/P) fimbriae, P. mirabilis fimbriae (PMF), uroepithelial cel...

We investigated the activity of curcumin against Proteus mirabilis and the struvite crystallization in relation to urinary stones formation. In order to evaluate an activity of curcumin we performed an in vitro experiment of struvite growth from artificial urine. The crystallization process was induced by Proteus mirabilis to mimic the real urinary tract infection, which usually leads to urinar...

PURPOSE Candida albicans (C. albicans) and Proteus species are causative agents in a variety of opportunistic nosocomial infections, and their ability to form biofilms is known to be a virulence factor. In this study, the influence of co-cultivation with Proteus vulgaris (P. vulgaris) and Proteus mirabilis (P. mirabilis) on C. albicans biofilm formation and its underlying mechanisms were examin...
