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...

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...

The isolated fungi species of different kinds from chromium contaminated soil sites located in Nagalkeni, Chennai were used for reducing chromium(VI) in a tannery industry wastewater of Nagalkeni, Chennai.  The experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(VI) in a tannery industry wastewater against the different pH, fungi biomass and ...

conclusions p. aeruginosa and s. marcescens can be good candidates for the detoxification of cr (vi) in soltan abad river. results the results indicated that pseudomonas aeruginosa and serratia marcescens were the most resistant bacteria with mics of 200 and 150 mg/l, respectively. both bacteria completely reduced 25 and 50 mg/l of cr (vi) in 36 hours and 48 hours, respectively. the growth rate...
