introduction: drug resistant staphylococci are the most important agents of nosocomial infections. in this survey, effect of different antibiotics on these bacteria and their drug resistance was investigated. methods: the study included 500 strains of staphylococci. minimum inhibitory concentrations of all antibiotics was determined by the broth macro dilution technique and standard methods fro...

BACKGROUND & OBJECTIVES Shigella flexneri is the most common species of Shigella causing diarrhoea and dysentery in Asia including India. Multidrug resistance in Shigella species has been reported worldwide and there is rising concern regarding development of fluoroquinolone resistance. This study was undertaken to find out the resistance pattern of Sh. flexneri, the commonest shigella isolated...

INTRODUCTION Antimicrobial resistance among bacteria that cause urinary tract infection (UTI) has been increasing since the introduction of chemotherapy. This study was aimed to assess the types of isolates from patients with UTI and to determine their current antimicrobial susceptibility profile. METHODS A record based retrospective analysis of bacterial uropathogens processed in the period ...

The objective of the present study was to evaluate the antibiotic susceptibility of 25 Listeria monocytogenes isolates isolated from raw cattle milk towards 15 antibiotics presently used in veterinary and human therapy. Antibiotic susceptibility tests were performed by using the Kirby Bauer disk diffusion method. The isolates were tested for their susceptibility to 15 different common antimicro...

To combat the threat to human health and biosecurity from antimicrobial resistance, an understanding of its mechanisms and drivers is needed. Emergence of antimicrobial resistance in microorganisms is a natural phenomenon, yet antimicrobial resistance selection has been driven by antimicrobial exposure in health care, agriculture, and the environment. Onward transmission is affected by standard...

Respiratory disease and diarrhea are the 2 most common diseases that result in the use of antimicrobial drugs in preweaned calves. Because the use of drugs in food animals, including dairy calves, has the potential for generating cross-resistance to drugs used in human medicine, it is vital to propose farm practices that foster the judicious use of antimicrobials while assuring animal health an...

This study investigated the resistance of various Salmonella strains to beta-lactam antibiotics. Salmonella Minnesota (36 strains) and Salmonella Heidelberg (24 strains) were isolated from broiler chickens and carcasses by the Disk Diffusion Test and resistance genes blaCTX-M-8, blaACC-1 and blaCMY-2 were detected by PCR. Of the 60 strains tested, 80% were resistant to at least one antibiotic. ...

BACKGROUND Healthcare liquid wastes are the reservoirs of harmful infectious agents such as the pathogens and multiple drug resistant microorganisms. Potential infectious risks include the spread of infectious diseases and microbial resistance from health-care establishments into the environment and thereby posing risks of getting infections and antibiotic resistance in the communities. OBJEC...

BACKGROUND Urinary tract infections (UTIs) are among the most common human infections. Many urinary tract bacteria are capable of expressing drug resistance. Resistant bacteria may be present from the commencement of the infection or may develop during treatment. This study focused on the problem of antibiotic resistance to the first-line drugs that were used to treat patients presenting with u...
