Molecular epidemiology of Shigella infections: plasmid profiles, serotype correlation, and restriction endonuclease analysis.
Plasmid isolation was used to refine the epidemiologic analysis for 168 shigellosis cases in Pima County, Ariz. Plasmids of less than 20 kb were used for comparison of plasmid profiles. Plasmid patterns for each species were distinct. A total of 57 of 74 (77%) Shigella flexneri strains could be placed into seven plasmid patterns, 70 of 79 (89%) Shigella sonnei strains could be placed into seven...
متن کاملCharacterization of endemic Shigella flexneri strains in Somalia: antimicrobial resistance, plasmid profiles, and serotype correlation.
One hundred twelve Shigella flexneri strain isolated from children with diarrheal disease in Somalia in 1983, 1984, 1988, and 1989 were analyzed for serotype, plasmid profile, and genetic location of antimicrobial resistance determinants. The prevalent serotypes were 4 (46% of the isolates), 1b (16%), 2a (16%), 3a (12%), and 6 (8%). Each serotype was associated with a characteristic predominant...
متن کاملMolecular epidemiology of DNA viruses: applications of restriction endonuclease cleavage site analysis.
Restriction endonucleases which cleave DNA at specific nucleotide sequences can be used to produce a set of DNA fragments of a viral genome which, when separated by gel electrophoresis, gives a characteristic "fingerprint" for that virus genome. This simple technique has been used to identify and classify DNA viruses of the herpes, adeno, and papova virus groups. Small variants within a given t...
متن کاملGlobal epidemiology of infections due to Shigella, Salmonella serotype Typhi, and enterotoxigenic Escherichia coli.
Enteric infections are a leading cause of disease and death in young children, particularly in the developing world [1]. In 1990, the World Health Organization (WHO) Global Burden of Disease estimated that diarrhoea contributed to 2.5 million deaths in children aged <5 years, representing 19.4% of total mortality in that age group [2]. Preliminary estimates from WHO for 2000 indicate that 1.6–2...
متن کاملEpidemiology of Salmonella enterica Serotype Dublin Infections
bacterium that typically causes bloodstream infections in humans. To summarize demographic, clinical, and antimicrobial drug resistance characteristics of human infections with this organism in the United States, we analyzed data for 1968–2013 from 5 US surveillance systems. During this period, the incidence rate for infection with Salmonella Dublin increased more than that for infection with o...
