conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...

background although effective strategies have been presented for preventing the spread of antibiotic resistance in iran, recent reports have revealed increasing antibiotic resistance among children and adults. objectives in the present study, we tried to provide a clear view of the antibiotic resistance status of aerobic organism as the most prevalent organism in patients with rhinosinusitis in...

A total of 273 Escherichia coli isolates from raw and treated municipal wastewaters were investigated to evaluate the frequency and persistence of antibiotic resistance and to detect the occurrence of conjugative R plasmids and integrons. The highest resistance rates were against ampicillin (22.71%), tetracycline (19.41%), sulfamethoxazole (16.84%) and streptomycin (14.28%). Multiple antibiotic...

The coliform bacterial population in the Grand Forks, N.Dak. sewage system was examined for multiple-antibiotic-resistant organisms over a 1-year period. Multiple-antibiotic-resistant coliforms were found to be common in the sewage, and their numbers remained fairly constant relative to the total coliform population throughout the year. Resistance to kanamycin, tetracycline, and ampicillin was ...
