background and objectives:  the most common problems limiting the medical use of aminoglycosides have been the nephro- and oto-toxicities as well as the increasing bacterial resistance. encapsulation of drugs into liposomes enhances their efficacy while reducing their toxicities. the aim of this study was to evaluate the antimicrobial activity of free and liposomal amikacin. material and method...

This study examined the sanitary conditions of public boreholes and hand dug wells water in relation to pathogenic bacteria isolated samples. To assess suitability drinking water, inspection surroundings sources was conducted, membrane filtration technic used trap microorganisms sample other standard microbiological technics were applied check heterotrophic plate counts, total coliforms, fecal ...

background & aim: antibacterial effect of the sealers which are used in root canal therapy is a factor which increases the rate of success in root canal therapy. the aim of this study was to compare the antibacterial effect of three sealers (zoe, ah26, dorifill) on two bacterial species, staphylococcus aureuse and streptococcus mutans immediately after mixing and one week after mixing. methods ...

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...

background protein a is the virulence factors of staphylococcus aureus rolling in its pathogenesis, and its gene is used for typing. polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) with different enzymes has been used for this action. objectives in this study, we used bsp143i enzyme for digestion of the gene, coding protein a (spa gene) in s. aureus. the bacteria w...
