OBJECTIVES To determine the in vitro resistance of group B streptococcus (GBS) to 12 antibiotics. To determine if there has been any decrease in sensitivity to the penicillins or other antibiotics currently used for GBS chemoprophylaxis in pregnant women. Find suitable alternative antibiotics to penicillin. Find an antibiotic that will have minimal selective pressure for resistance among the en...

Commentary The meta-analysis by Vollenweider and colleagues finds that antibiotics reduce treatment failure in outpatients and inpatients alike, yet emphasizes a sensitivity analysis limited to currently used antibiotics that yielded similar relative risks but lacked power to demonstrate statistical significance. This sensitivity analysis seems somewhat arbitrary if antibiotic efficacy in COPD ...

Although the use of antibiotics in the developed countries is done under certain principles, there is an opposite situation at the use of antibiotics in the underdeveloped countries which is irregular. The prevalence of antibiotic use in the fight against infectious diseases additionally raises the problem of increasing resistance of the micro-organisms against antibiotics. There is also an inc...

ba ckground: legionella pneumophila is  a  dangerous pathogenic bacterium can cause serious infectious diseases especially in hospitalized immuno-compromised patients. this bacterium is shown to be resistant against different antibiotics. resistance against a wide range of antibiotics is usually mediated by efflux pump in bacteria. efflux pumps are proteinaceous transporters localized in the cy...

The evolution of resistance to a single antibiotic is frequently accompanied by increased resistance to multiple other antimicrobial agents. In sharp contrast, very little is known about the frequency and mechanisms underlying collateral sensitivity. In this case, genetic adaptation under antibiotic stress yields enhanced sensitivity to other antibiotics. Using large-scale laboratory evolutiona...

BACKGROUND/PURPOSE To document the trends of sensitivity and to find whether it is necessary to change antibiotics in selected patients according to the sensitivity test results in our clinical practice. METHODS We collected urine culture results from 0-18-year-old patients in the National Taiwan University Hospital from January 1, 2003 to October 31, 2012. Their medical chart was reviewed to...

Infectious coryza is a respiratory disease of chicken primarily affecting upper respiratory tracts. Six outbreaks of infectious coryza were investigated from Andhra Pradesh. Three of them were in commercial chicken, two from native Aseel chicken and one from emu. Out of total 74 infra orbital sinus swabs tested, 27 (36.4%) gave isolates of Avibacterium paragallinarum. All the 27 isolates obtain...

background: methicillin resistant staphylococcus aureus (mrsa) nasal carriers play role in development of nosocomial infections and may increase treatment costs and mortality rate. these isolates, in addition to beta lactamase, is resistant to other drugs. carrier frequency and spectrum awareness of drug sensitivity in these isolates will be useful in choosing more effective methods of control ...
