Allicin from garlic inhibits the biofilm formation and urease activity of Proteus mirabilis in vitro.

Several virulence factors contribute to the pathogenesis of Proteus mirabilis. This study determined the inhibitory effects of allicin on urease, hemolysin and biofilm of P. mirabilis ATCC 12453 and its antimicrobial activity against 20 clinical isolates of P.

Prevalence of the genes encoding aminoglycoside-modifying enzymes and methicillin resistance among clinical isolates of Staphylococcus aureus in Tehran, Iran.

Aminoglycosides are potent bactericidal agents that play an important role in antistapylococcal therapy. In this study, we used a multiplex polymerase chain reaction assay to investigate the prevalence of aac(6')-Ie/aph(2''), ant(4')-Ia, and aph(3')-IIIa, the genes encoding the most clinically prevalent aminoglycoside-modifying enzymes, and simultaneous detection of the methicillin resistance gene, mecA, in Staphylococcus aureus isolates. A total of 100 S.
