Salmonella genomic island 1 (SGI1) and variants (SGI1-I and the new variant SGI1-O) were mapped in five strains of Proteus mirabilis isolated from humans and food in China. Sequencing showed that SGI1 and variants were integrated at the 3' end of the chromosomal thdF gene as previously described for Salmonella strains.

A bacteriphage typing scheme for differentiating Proteus isolated from clinical specimens was developed. Twenty-one distinct patterns of lysis were seen when 15 bacteriophages isolated on 8 Proteus mirabilis, 1 P. vulgaris, and 1 P. morganii were used to type 162 of 189 (85.7%) P. mirabilis and P. vulgaris isolates. Seven phages isolated on 3 P. morganii were used to type 13 of 19 (68.4%) P. mo...

Intensive care unit (ICU) patients frequently have consequences from healthcare-associated infections (HAIs), which include bacteremia, pneumonia, urinary tract, skin, or soft tissue infections. . In this study, a total of 100 clinical specimens (urine, sputum and pus) were collected admitted in the ICU. Results showed eighty two positive growth culture ‎and to intensive distributed 1 (1.2%) Kl...

The antibacterial and anti-biofilm activity of ethanolic extract from the rhizome of Zingiber officinale were evaluated. In vitro antibacterial activity was investigated by microdilution method. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) have been determined. The values were in the range from 0.0024 to > 20 mg/ml. The most sensitive bacteria were Gram-po...

Proteus mirabilis (P. mirabilis) is a species of Gram-negative and facultative anaerobic bacteria that shows swarming motility and urease activity. Proteus ranked third as the cause of hospital-acquired infections [1]. The organism is rod-shaped and motile bacterium with diverse mode of transmission [2]. P. mirabilis is a common causative organism of urinary tract infection (UTI) in the complic...

BACKGROUND Proteus mirabilis is an opportunistic pathogen, commonly associated with complicated urinary tract infections (UTIs). UTIs caused by multidrug-resistant Proteus mirabilis have increased worldwide. Multidrug-resistance of Gram-negative enteric bacteria is usually associated with class 1 integrons. PURPOSES To investigate the prevalence and characterize gene cassettes of class 1 inte...
