The problem of infection has been persistent in the surgical world even after the introduction of antibiotics. Pathogens that infect surgical wounds can be part of normal flora or acquired from the hospital environment or other infected patients. Staphylococcus aureus, being the normal microbial flora of the skin is one of the commonest causes of wound infection. A total of 1088 pus samples fro...

The adsorption property of activated charcoal on verotoxin (VT)-producing Escherichia coli (VTEC) was examined using E. coli O157:H7. In the present study, E. coli O157:H7 strains were effectively adsorbed by activated charcoal. Adsorption was dose-dependent, and the maximum adsorption occurred within 5 min. At 10 mg of activated charcoal, bacteria tested were completely adsorbed. Activated cha...

OBJECTIVES The aim of this study was to determine the anaerobic spectrum of activity of REP3123, a novel diaryldiamine that inhibits bacterial methionyl-tRNA synthetases in Gram-positive bacteria. METHODS Fifty recent clinical isolates of Clostridium difficile from patients diagnosed with C. difficile infection and 223 other intestinal normal flora anaerobes were tested for their susceptibili...

All humans are infected with bacteria (the normal flora) living on their external surfaces (including the skin, gut and lungs). We are constantly also exposed to bacteria (including air, water, soil and food). Normally due to our host defenses most of these bacteria are harmless. In compromised patients, whose defenses are weakened, these bacteria often cause opportunistic infectious diseases w...

OBJECTIVE To study the effect of phage lysin on the growth of lysogens. METHODS Sputum specimens processed by modified Petroff's method were respectively treated with phagebiotics in combination with lysin and lysin alone. The specimens were incubated at 37 °C for 4 days. At the end of day 1, 2, 3 and day 4, the specimens were streaked on blood agar plates and incubated at 37 °C for 18-24 hou...

Pasteurella multocida, a gram-negative coccobacillus, part of the normal oral flora many domestic and wild mammals, has been described widespread veterinary pathogen potential to cause zoonotic infections in humans resulting from injuries caused by household or pets.

conclusions: according to our experiment, onion has an inhibitory effect on the growth of normal eye flora; although the duration of onion juice instillation did not show any significant effect on the group results. hence, this finding is an initiating point for further investigations into the antimicrobial properties of this herb to treat common eye infections, including conjunctivitis and ble...

Enterococci are Gram positive and catalase- negative cocci that are found in the gastrointestinal tract of mammals and birds, and are readily isolated from soil, surface and waters. The aim of this study was to discriminate between Enterococcus isolates based on repetitive element sequence based –PCR (Rep-PCR) with the BOXA2R primer and their antibiotics profile. Enterococci isolates were obtai...

Bachtiar et al. (2014) present a very interesting study in which they illustrate the ability of AI-2, produced by Aggregatibacter actinomycetemcomitans to inhibit biofilm formation by the fungal opportunistic pathogen Candida albicans. C. albicans is considered to be the most common fungal pathogen of humans, manifesting itself in the oral cavity (oral candidiasis or thrush), female reproductiv...
