Antibiotics are of equal importance to antitoxin in the treatment of diphtheria, as an effective antibiotic rapidly halts the production of toxin. There appear to have been only two reports of the sensitivity of diphtheria bacilli to various antibiotics and these are based on the examination of less than 60 strains. In this paper the sensitivity of 192 strains to eight representative antibiotic...

BACKGROUND Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-ex...

         Urine specimens collected from in-patients and out-patients in Urmia Imam Hospital, northwest Iran, were cultured on blood agar and Eosin Methylene Blue agar. Isolated bacteria were identified according to standard microbiological tests and then subjected to sensitivity testing according to routine method of disk agar diffusion technique. Out of 8044 and 10425 urine specimens, 8.7% and...

BACKGROUND AND OBJECTIVES Cystic fibrosis patients suffer from chronic lung infections that require long-term antibiotic therapy. Pseudomonas readily evolve resistance, rendering antibiotics ineffective. In vitro experiments suggest that resistant bacteria may be treated by exploiting their collateral sensitivity to other antibiotics. Here, we investigate correlations of sensitivity and resista...

Thirty isolates of Bacillus anthracis recovered from animal carcasses, soil and human in different localities in Iran between 2007 and 2008. They were tested by standard disc diffusion susceptibility method for their resistant/ susceptibility to different kinds of antibiotics. According to American National Committee of Clinical Laboratory Standards (NCCLS) guidelines all isolates were sensi...
