OBJECTIVES To assess the frequency of serogroups and serotypes, as well as the antimicrobial susceptibility pattern of Shigella species isolated from known cases of diarrhoea and dysentery from Karachi, Pakistan. METHODS A cross-sectional study was conducted between January 2002 and March 2003 at Aga Khan University on stool samples received from children with diarrhoea and dysentery from fou...
Shigella species were discovered over 100 years ago by a Japanese microbiologist named Shiga, for whom the genus is named. Shigella organisms are a group of gram-negative, facultative intracellular pathogens. They were recognized as the etiologic agents of bacillary dysentery or shigellosis in the 1890s. These organisms are members of the family Enterobacteriaceae and tribe Escherichieae; they ...
OBJECTIVES The objective of this study was to assess the presence of mcr-1 in Shigella sonnei isolated in Vietnam. METHODS WGS data were analysed for the presence of the mcr-1 gene sequence. The association of mcr-1 with a plasmid was assessed by PCR and by conjugation. RESULTS Through genome sequencing we identified a plasmid-associated inactive form of mcr-1 in a 2008 Vietnamese isolate o...
Shigellosis causes diarrheal disease in humans in both developed and developing countries, and multi-drug resistance in Shigella is an emerging problem. Understanding changing resistance patterns is important in determining appropriate antibiotic treatments. This meta-analysis systematically evaluated aminoglycoside resistance in Shigella. A systematic review was constructed based on MEDLINE an...
Active immunization of guinea pigs and rabbits with outer membrane proteins (OMP) isolated from Shigella flexneri 3a and Shigella sonnei phase I protected the animals against keratoconjunctivitis shigellosa induced with the homologous or heterologous strain. Protection was also achieved in rabbits after passive immunization with anti-OMP immune serum. Active immunization with lipopolysaccharide...
Diarrhoeal disease is still considered a major cause of morbidity and mortality among children. Among diarrhoeagenic agents, Shigella should be highlighted due to its prevalence and the severity of the associated disease. Here, we assessed Shigella prevalence, drug susceptibility and virulence factors. Faeces from 157 children with diarrhoea who sought treatment at the Children's Hospital João ...
INTRODUCTION Shigellosis, or bacillary dysentery, is a bloody diarrhea caused by the invasion of the human colonic and rectal mucosa by Shigella, a gramnegative microorganism belonging to the family enterobacteriaceae. In the developing world, children are the major victims with 600,000 deaths every year. The symptoms are characterized by early watery diarrhea rapidly followed by fever, intesti...
BACKGROUND AND OBJECTIVES Strains of Shigella spp. can cause shigellosis, or bacillary dysentery. that is a public health problem worldwide. The aim of this study was to describe the population structure and genetic relatedness of multidrug resistant S. sonnei and S. flexneri isolated during a one year period from children with diarrhea in Tehran, Iran. MATERIALS AND METHODS A total of 70 Shi...
shigella species are among the common causes of bacterial diarrhoeal diseases. traditional detection methods are time-consuming resulting in delay in treatment and control of shigella infections thus there is a need to develop molecular methods for rapid and simultaneous detection of shigella spp. in this study a rapid multiplex pcr were developed for simultaneous detection of three pathogenic ...
The in vitro antibacterial activity of cinoxacin was compared with that of ampicillin and chloramphenicol against 26 strains of nontyphoid Salmonella and 44 strains of Shigella. Cinoxacin was found to have a lower minimal inhibitory concentration than ampicillin and chloramphenicol against all Salmonella and Shigella sonnei strains. Cinoxacin had minimal inhibitory concentrations similar to tho...
