This study aims to evaluate the positive predictive value (PPV) and the negative predictive value (NPV) of Vitek2 in detecting extended-spectrum beta-lactamase (ESBL) phenotypes when compared to a manual confirmatory test as gold standard. A sample of Escherichia coli, Klebsiella spp and Proteus mirabilis isolates were collected by 5 laboratories in the Emilia-Romagna Region (Italy). Vitek2 app...

BACKGROUND Bloodstream infection (BSI) is a life-threatening condition that requires rapid antimicrobial treatment. METHODS We determined the prevalence of bacterial isolates associated with BSI at Bukavu General Hospital (BGH), South Kivu Province, Democratic Republic of the Congo, and their patterns of susceptibility to antimicrobial drugs, from February 2013 to January 2014. RESULTS We c...

This study aimed to identify biological contaminants of banana in vitro cultures. We also tested the effect of Zn or ZnO nanoparticles on elimination of some bacterial and fungal contaminants and their influence regeneration. Nine strains of bacterial contaminants (Cellulomonas uda, Cellulomonas flarigena, Corynebacterium panrometabolum, Bacillus megaterium, Staphylococcus spp., Klebsiella spp....

Urinary tract infection (UTI) is one of the most common canine infections, and among the most common indications for antimicrobial therapy. Although a presumptive diagnosis of UTI can be made based on the clinical signs along with a urinalysis, urine culture and sensitivity testing is indicated for the definitive diagnosis as well as for the choice of appropriate antimicrobial therapy (Ling, 20...

Detection and intensity of urease activity in enterobacteriaceae greatly varies as a function of the media or techniques used, or both. A comparative investigation on several solid and liquid media led us to the following conclusions. (i) Detection of Proteus spp. can be adequately performed with the highly selective solid medium described by Cook (1948), as well as with the different liquid me...

Urinary tract infection is one of the most serious infectious disease in world , This study aimed to isolate and diagnose bacteria that cause UTI then evaluate its ability form a biofilm. 100 urine samples were collected for group patients attending Al-Diwaniyah Teaching Hospital, who confirmed have at different ages. The results showed presence bacteria. Escherichia coli proteus spp all sample...

This study aimed to evaluate 50 different cheese samples in terms of certain microbiological parameters. The presence Salmonella spp. and Listeria cheeses were investigated by immunomagnetic separation conventional methods. Staphylococcus aureus was detected 4 samples, while 2 accepted suspicious 5/50 found positive with respect isolates determined as Proteus mirabilis. Therefore, not from the ...
