Antibiotic resistance among Shigella serogroups isolated in Tehran, Iran (2002-2004)
Shigellosis, one of the most common bacterial diarrhoeal diseases, is endemic throughout the world. It is one of the major causes of morbidity in children with diarrhoea in Iran [1-4]. Antibiotic therapy is useful and effective for shigellosis. Treatment is critical for persons with severe disease, particularly children and immunosuppressed patients. Use of an appropriate antibiotic therapy can shorten the duration of symptoms, significantly reduce the risk of transmission, and also prevent potentially lethal complications [5-7]. However, high frequencies of resistance in
Characterization of endemic Shigella boydii strains isolated in Iran by serotyping, antimicrobial resistance, plasmid profile, ribotyping and pulsed-field gel electrophoresis
Background: Shigellosis is one of the major causes of morbidity in children with diarrhea in Iran. The present study was undertaken to characterize apparently sporadic Shigella boydii strains isolated from pediatric patients in Iran. Findings: Ten S. boydii strains isolated from pediatric cases of gastroenteritis and acute diarrhea in Tehran between December 2002 and November 2003 were submitted to serotyping, antimicrobial susceptibility testing, plasmid profile analysis, ribotyping and pulsed field gel electrophoresis (PFGE). Seven isolates were attributed to serotype 2, whereas the remaining three belonged to serotypes 14, 18, 19, respectively. Six drug resistance phenotypes (R1 to R6) w…
