Background: Staphylococcus aureus is a major food-borne pathogen worldwide and a frequent contaminant of fruit juices. This study aimed to evaluate the antibacterial activity of bacteriocin-containing Cell-Free Culture Supernatants (CFCS) of Pediococcus pentosaceus IO1 against S. aureus inoculated in fruit juices, as well as their impact on the juice sensory attributes. Methods: The orange and...

background coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...

entrapment of permeabilized whole cells within a matrix is a common method for immobilization. chitosan possesses distinct chemical and biological properties, which make it a suitable matrix for entrapment and immobilization of penicillin g acylase (pga). in the first step, escherichia coli (atcc 11105) cells were permeabilized using n-cetyl-n,n,n-trimethyl ammonium bromide (ctab) (0.1% w/v, 45...

An animal model was designed to study the effect of large volume Hypertonic Solutions (HTS) for re‌suscitation following a hypovolemic shock. Resuscitation in hypovolemic animals was performed by infusion of 15 ml/kg of normal saline (group I), 5% sodium bicarbonate (NaHCO3) (group II), 5% sodium chloride (NaCI) and 7.5 % NaHCO3 1:1 VN (group III), 5% NaC1 (group IV), and 5% NaCl and 5% serum a...
