OBJECTIVES To compare the in vitro activities of vancomycin and linezolid against methicillin resistant Staphyloccus aureus in our set up to help in formulating a better empirical treatment and reduce the emergence of vancomycin resistant Staphylococcus aureus. METHODS The study was conducted over a period of 6 months (1st July 2009-31st Dec 2009). Fifty Methicillin resistant Staphylococcus a...

According to current interpretive criteria, Neisseria gonorrhoeae isolates with ciprofloxacin minimum inhibitory concentrations (MICs) of ≤ 0.06 μg/mL are considered susceptible. Intermediate and resistant MIC breakpoints have not yet been established but isolates of N. gonorrhoeae with ciprofloxacin MICs of 0.05 to 0.25 μg/mL have been associated with apparent treatment failure with a regimen ...

Commentary Background Reports of a gonorrhoea 'superbug' made the headlines last year following the description of a ceftriaxone-resistant i solate of Neisseria gonorrhoeae. 1 But is antimicrobial resistance a significant problem and what is the current reality of N. gonorrhoeae infection in the UK? Is gonorrhoea getting meaner? Anogenital infection with N. gonor-rhoeae has been highly responsi...

Acquired resistance of Helicobacter pylori to metronidazole and clarithromycin has been reported, with metronidazole resistance being very common. This has an important clinical impact on dual therapies, as well as on the standard triple therapies. However, when antisecretory drug based triple therapies with amoxycillin or clarithromycin and metronidazole are used, the resistance can be overcom...

In this study, the minimum inhibitory concentrations (MICs) of AgNO3 against bacteria were investigated in a variety of microorganism culture broths. Broth- and light-dependent MIC values were observed and correlated negatively with nano-Ag speciation development. We advocate here the importance of broth and light standardization in Ag antimicrobial test.

Combined effect of ciprofloxacin (Ci) and amoxycillin (Ax) has been studied in vitro against 12 clinical isolates of S. typhi that showed Ci minimum inhibitory concentration (MIC) of > or =1 microg/ml. By agar dilution method, MIC values of Ax were 10-16 microg/ml for 11 isolates and 0.5 microg/ml for the remaining one isolate. The isolates, when treated with Ci and Ax in combination, showed fr...

Healthy volunteers received a single dose of gatifloxacin and moxifloxacin (400 mg each), and serum samples were obtained from these volunteers over a 24-h period. Prolonged (> or =12 h) serum bactericidal activity (SBA) was observed for both agents against staphylococcal isolates with minimum inhibitory concentrations (MICs) of gatifloxacin of < or =0.5 mug/mL. In strains with gatifloxacin MIC...

zhumeria majdae is a rare an endemic medicinal plantspecies grown wild in iran. the hydro distilled essential aerial part oil of z. majdae analysed by gc–ms. thirty-one compounds representing 95.36% of the aerial part oil, respectively, were identified, of which linalool (48.14%), camphor (20.71%), limonene (4.83%), trans-linalool oxide (2.69%), 3-octanone (2.34%), terpinene-4-ol (2.30%), camph...
