We identified 3 atypical Shigella flexneri varieties in China, including 92 strains with multidrug resistance, distinct pulse types, and a novel sequence type. Atypical varieties were prevalent mainly in developed regions, and 1 variant has become the dominant Shigella spp. serotype in China. Improved surveillance will help guide the prevention and control of shigellosis.
The ability of bivalent Salmonella typhi-Shigella sonnei vaccine strain 5076-1C to stimulate an intestinal immunoglobulin A response in humans was evaluated by detecting gut-derived, trafficking antibody-secreting cells (ASC) in peripheral blood. Following vaccination, an immunoglobulin A-ASC response to O antigens of S. typhi and S. sonnei was observed in 10 of 13 and 13 of 13 vaccine recipien...
prevalence and multiple drug resistance of shigella sonnei isolated from diarrheal stool of children
background : science the discovery of antibiotic, the incidence of antibiotic resistance has been inevitable. although there has been many study in these area but problem still exists. the aim of this research was to study the serotyping and multiple antibiotic resistance patterns of shigella sonnei isolated from diarrheal stool of children. methods : the stool samples of children from zero...
background and objectives : shigella, causative of bacillary dysentery, has two colony forms. the loss of large virulence plasmid from virulent shigella sonnei form i, during cell storage and subculturing, lead to avirulent form ii. environmental factors, e.g. culture media composition, could affect the conversion of the bacterial forms. materials and methods : in this study, some components, i...
background infections caused by shigella are a major cause of diarrheal disease in the developing and developed countries. the present study was conducted to apply and evaluate arbitrarily primed pcr (ap-pcr) for investigation of genetic relatedness among the strains of shigella sonnei isolated from cases of acute diarrhea in tehran. patients and methods totally, 60 s. sonnei strains isolated f...
Background: Shigella spp. are gram negative bacteria, which are of global public health importance. The growing of multidrug-resistant Shigella isolates are a major problemaround the world. Methods: Overall, 50 isolates of Shigella spp. from children diarrheic stools w...
OBJECTIVES To study the incidence and clinical picture of Shigella associated reactive arthritis (ReA) and the arthritogenicity of various Shigella species in the population. METHODS A questionnaire on enteric and extraintestinal, especially musculoskeletal, symptoms was sent to 278 consecutive patients with Shigella positive stool culture and to 597 controls. Analysis of self reported muscul...
