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,...

The interrelationships between P blood group phenotype, proteus antibodies and rheumatoid arthritis (RA) were investigated in 140 patients with RA and 114 of their siblings who did not have RA. In the group with RA P2 subjects had significantly higher titres of proteus antibodies than P1 patients. This was not observed in the group without RA, or for antibodies to Escherichia coli. Although C r...

The object of this review is the genus Proteus, which contains bacteria considered now to belong to the opportunistic pathogens. Widely distributed in nature (in soil, water, and sewage), Proteus species play a significant ecological role. When present in the niches of higher macroorganisms, these species are able to evoke pathological events in different regions of the human body. The invaders...

Three aminoglycoside antibiotics and two penicillins were compared for their in vitro activity against 60 isolates of Serratia, Pseudomonas, Proteus mirabilis, and indole-positive Proteus sp. Testing was done by the agar dilution method using Mueller-Hinton broth solidified with 1.5% agar. The activity of amikacin, aminodeoxybutirosin, and gentamicin against Proteus and Pseudomonas, as related ...

Ovarian and paraovarian neoplasms are uncommon in children, mainly originating from germ cell tumors and, least frequently, epithelial tumors. There is an association between genital tract tumors and Proteus syndrome, a rare, sporadic, and progressive entity, characterized by a postnatal overgrowth in several tissues caused by a mosaic mutation in the AKT1 gene. We describe a 20-month-old asymp...

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...

25 26 27 Salmonella genomic island 1 (SGI1) and variants (SGI1-I and the new variant SGI128 O) were mapped in five strains of Proteus mirabilis isolated from humans and food 29 in China. Sequencing showed SGI1 and variants were integrated at the 3’-end of the 30 chromosomal thdF gene as previously described in Salmonella strains. 31
