INTRODUCTION Gonorrhea is one of the most common sexually transmitted infections (STls) in developing countries, and the emergence of resistance to antimicrobial agents in Neisseria gonorrhoeae is a major obstacle in the control of gonorrhoea. Periodical determination of the prevalence and monitoring of antimicrobial susceptibility of N. gonorrhoeae is essential for the early detection of emerg...

a total number of 259 gram negative bacteria (entero-bacteria) isolated during the years 1973-1974 was examined. these strains were isolated from sick children referred and or hospitalized in a children hospital in tehran. the strains consisted of ; 131e.coli, 52 salmonella, 40 klebsiella, 18 shigella, 13 proteus, 3 enterobacter and 2 citrobacter. sensitivity tests were performed according to t...

Successful treatment of canine pyoderma has become compromised owing to the development of antimicrobial resistance with accompanying recurrence of infection. Canine skin samples submitted to a veterinary diagnostic laboratory for microbiological culture and sensitivity between January 2007 and June 2010, from which Staphylococcus intermedius was isolated, were selected for this investigation. ...

Background: The survival of pathogens in biofilms poses a threat to food safety. The aim of this study was to determine prevalence, antimicrobial resistance, and molecular characterization of Escherichia coli strains. Methods: Swab samples (n=144) were collected from biofilm formed on food contact surfaces in seafood pre-processing plant in India. E. coli was isolated and identified using uid ...

conclusions the findings of the present study well demonstrated that the p. aeruginosa biofilm-producing isolates were more resistant to the tested antibiotics. furthermore, because of wide distribution, it seems that the psla gene is associated with biofilm formation. results biofilm formation was observed in 70% of the p. aeruginosa isolates. the potential formation of biofilm was significant...

Background: The emergence of antimicrobial resistance results in morbidities and mortalities associated with many bacterial infections is a major concerning issue front the healthcare system. As part competitive adaptive strategy for its growth, gram-positive bacteria like Bacillus subtilis produce peptides; bacteriocins. These peptides protect other species. Objectives: To counter resistance, ...

  Objective(s):   The ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. The perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. Lichens are known pro...

BACKGROUND The prevalence of resistant Pseudomonas aeruginosa isolates is increasing and it is considered as one of the major public health concerns in the world. The association between integrons and drug resistance has been proven and evidences suggest that integrons are coding and responsible for dissemination of antibiotic resistance among P. aeruginosa isolates. OBJECTIVE This study is a...

introduction:   the resistance of pathogenic bacteria to antibiotics has now raised an issue worldwide. as the e.coli is the most common cause of urinary tract and nosocomial infections, the present study was designed to determine the antimicrobial susceptibility of e.coli in the urine culture of patients admitted to imam reza hospital in kermanshah. material and methods: for this descriptive s...
