one of the great challenges in the treatment of infectious diseases is the resistance of pathogenic bacteria against antibiotics, and antibiotic resistance to shigella is broadly observed in different parts of the world. the object of this study was to determine shigella antibiotic resistance pattern against the antibiotics such as ampicillin, amoxicillin, trimethoprim-sulfamethoxazole, chloram...

objective(s): macrolide resistant streptococcus pneumoniae pose an emerging problem globally. the aim of this study was to investigate the prevalence of ermb and mefa genes (macrolide resistant genes) by polymerase chain reaction (pcr) method and to detect drug resistance patterns of s. pneumoniae isolated from clinical samples to macrolides and other antibiotic agents by e-test method. materia...

antibiotic resistance pattern of salmonella and e. coli isolated from chickens against several antibiotics was determined. a total of 150 samples from chickens were isolated and identified using various enrichment and special media. disc diffusion antibiotic susceptibility test was performed and mic and mbc of doxycycline were also determined using serial dilution method. sixty nine bacterial i...

The spatial distribution of antibiotic resistance to streptomycin and kanamycin was examined in natural bacterial communities of two streams. The proportion of resistant bacteria was substantially higher (P < 0.05) in the midreaches of an industrially perturbed stream, but no such pattern was apparent in an undisturbed reference stream. The highest relative frequency of resistance was found at ...

Temporal variabilities in the genetic patterns and antibiotic resistance profiles of enterococci were monitored over a 7-month period. Enterococcus faecalis isolates (103 strains) collected from feces showed only one genetic pattern and antibiotic resistance profile within 0 d and 30 d. In contrast, after 60 d and 90 d, the genetic patterns and antibiotic resistance profiles of all E. faecalis ...

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...

The present study investigates the prevalence of antibiotic resistance among bacterial isolates from different environmental samples and determines their resistance patterns. Bacteria were isolated from the Ganges water, the intestine of Labeo rohita, soil samples from agricultural land, and clinical samples of urine, pus, and throat swab. The bacterial isolates were identified on the basis of ...
