results amongst 938 stool samples, 36 were shigella spp. s. sonnei (61.1%, n = 22), which was the most common, followed by s. flexneri (27.8%, n = 10), s. boydii (8.3%, n = 3), and s. dysenteriae (2.8%, n = 1). furthermore, most shigella isolates showed resistance to amoxicillin (83.3%), tetracycline (61.1%), and co-trimoxazole (83.3%). no resistance was found against ciprofloxacin and imipenem...

Antibacterial properties of methanolic extracts of F. indica prepared in different doses against seven Gram-positive and Gram-negative bacterial strains i.e. Streptococcus pyogenes, Staphylococcus aureus (1), Staphylococcus aureus (2), Shigella sonnei, Escherichia coli (1), Escherichia coli (2) and Neisseria gonorrhoeae using agar well diffusion method (inhibition zone measurements) compared to...

Shigella sonnei is the most frequent cause of shigellosis in the United States. Epidemiologic studies of this organism have been hampered by the lack of adequate typing procedures. Ribosomal DNA analysis (ribotyping), a method which analyzes restriction fragment length polymorphisms in the chromosomal genes that encode rRNA, has recently been shown to be useful for microbial species identificat...

Between 2002 and 2007, travel related cases of Shigella sonnei and S. flexneri in Alberta, Canada were acquired from Central America, the Indian subcontinent and North America. Of this group, resistance to ciprofloxacin and nalidixic acid was identified in isolates from patients who had travelled to the Indian subcontinent. This study provides a Canadian perspective to a growing body of literat...

AIM This study aims to determine the serogroup distribution and molecular diagnosis, as well as antimicrobial resistance profiles among Shigella spp. isolated from patients with diarrhea in Kerman, southeast of Iran. BACKGROUND Shigella species are frequent cause of bacterial dysentery worldwide. Previous studies have been reported that S. sonnei and S. flexneri are the most prevalent serogro...

In this study, 153 clinical isolates of Shigella were screened for extended-spectrum beta-lactamase (ESBL) production by double-disk synergy test. After being confirmed by the combined disk-test and inhibitor-combined E-test strips, all positive isolates were tested for the bla gene by PCR and the enzymes by isoelectric focusing. DNA sequencing of PCR products revealed that five Shigella sonnei...

BACKGROUND Emergence of extended-spectrum beta-lactamases (ESBLs) in Shigella species imparting resistance to third-generation cephalosporins is a growing concern worldwide. The aim of this study is to molecularly characterize the newly emerging beta-lactam resistant Shigella sonnei, specifically ESBLs in Lebanon, and compare them to beta-lactam sensitive isolates. METHODOLOGY We compared fiv...

This report deals with serological and biochemical relationships between members of the genus Escherichia and Escherichia-like paracolon bacteria and the microorganisms that are usually classified as Shigella di8par. These studies are part of an investigation on the interrelationships within the family Enterobacteriaceae that was started in 1942 and which is still in progress. Shigella ceylonen...
