Salmonella infections are one of the major global public health problems. During the last decade, antibiotic resistance and multiresistance of Salmonella spp. have increased a great deal, especially in developing countries with an increased and indiscriminate use of antibiotics in the treatment of humans and animals. This study aims to investigate and compare antimicrobial susceptibility patter...

Shigellosis is an important public health problem, especially in developing countries. Antibiotic treatment of bacterial dysentery, aimed at resolving diarrhea or reducing its duration is especially indicated whenever malnutrition is present. First-line drugs include ampicillin and trimethoprim sulfamethoxazole(TMP-SMX); however multidrug-resistance has occurred and careful antibiotic selection...

The aim of the present study was to evaluate antimicrobial susceptibility patterns with special reference to multidrug resistance, susceptibility to ciprofloxacin, and bacteriophage typing of Salmonella enterica serotype Typhi isolated from blood sent for culture in a tertiary-care teaching hospital in eastern Nepal during January 2000-December 2004. In total, 132 strains of S. enterica Typhi, ...

Typhoid fever continues to remain a health problem as the causative organism Salmonella Typhi has developed resistance to many of the antibiotics used. This study was undertaken to determine the current pattern of resistance to antimicrobial agents and phage types of S.Typhi isolates obtained in a tertiary health care hospital in Pondicherry. Blood culture was done for 1296 suspected cases of e...

AIMS To test the sensitivity of strains of Campylobacter species isolated from humans in England and Wales against a range of antimicrobial agents for the purpose of monitoring therapeutic efficacy and as an epidemiological marker. METHODS An agar dilution breakpoint technique was used to screen isolates against ampicillin, chloramphenicol, gentamicin, kanamycin, neomycin, tetracycline, nalid...

Shigella infection has been occurring in both epidemic and sporadic forms on Andaman and Nicobar Islands in India (92 to 94°E longitude, 6 to 14°N latitude; Bay of Bengal). Although acute gastrointestinal infection clinically resembling shigellosis has been reported on the islands frequently, bacteriological surveillance was only started in 1994. The surveillance data showed that shigellosis is...

Background & Aims: One of the most common causes of bacterial resistance to beta-lactam antibiotics is beta-lactamase producing. The aim of this study was to compare the antibiotic resistance of urinary Escherichia coli (E. coli) isolates producing CTX-M and TEM type beta-lactamases, and to determine the strains with co-resistance to multiple antibiotics in Mashhad, Iran. Methods: E. coli b...

Methyl gallate is a major component of Galla Rhois, as carvacrol is of oregano essential oils. Both have shown good antibacterial activity against intestinal bacteria. This study investigated the antibacterial activities of nalidixic acid in combination with methyl gallate and carvacrol against nalidixic acid resistant bacteria. The combined effect of nalidixic acid with methyl gallate and carv...

Cinoxacin is a new synthetic compound similar chemically and in antimicrobial activity to oxolonic acid and nalidixic acid. It is most effective against Escherichia coli and Proteus mirabilis, but at concentrations expected in the urine it is inhibitory for all species of Enterobacteriaceae. Relative to nalidixic acid, cinoxacin has slightly greater inhibitory and bactericidal activity, less in...
