Serological cross-sectional studies on salmonella incidence in eight European countries: no correlation with incidence of reported cases
BACKGROUND Published incidence rates of human salmonella infections are mostly based on numbers of stool culture-confirmed cases reported to public health surveillance. These cases constitute only a small fraction of all cases occurring in the community. The extent of underascertainment is influenced by health care seeking behaviour and sensitivity of surveillance systems, so that reported inci...
متن کاملRecombination in the Evolution of Enterovirus C Species Sub-Group that Contains Types CVA-21, CVA-24, EV-C95, EV-C96 and EV-C99
Genetic recombination is considered to be a very frequent phenomenon among enteroviruses (Family Picornaviridae, Genus Enterovirus). However, the recombination patterns may differ between enterovirus species and between types within species. Enterovirus C (EV-C) species contains 21 types. In the capsid coding P1 region, the types of EV-C species cluster further into three sub-groups (designated...
متن کاملSerotype and phage type distribution of salmonella strains isolated from humans, cattle, pigs, and chickens in the Netherlands from 1984 to 2001.
We studied serotypes and phage types of Salmonella strains isolated from humans and animals in The Netherlands over the period 1984 to 2001. All human strains (n = 59,168) were clinical isolates. The animal strains (n = 65,567) were from clinical and nonclinical infections. All isolates were serotyped, and Salmonella enterica serovar Typhimurium and serovar Enteritidis strains were further phag...
متن کاملGENERATION OF A GENE CONSTRUCT TO SIPA GENE DELETION OF SALMONELLA TYPHIMURIUM
Background & Aims: Salmonella Typhimurium is a negative-gram, non-spore, free capsule, moving bacteria with Trish Perry flagella. Salmonella is the most common cause of food poisoning. The ability to enter and survive in host cells is the condition for pathogenic Salmonella species. Proteins of invasive Salmonella are transferred to the host cells by bacteria. This study was performed for gener...
متن کاملBarriers to recombination between closely related bacteria: MutS and RecBCD inhibit recombination between Salmonella typhimurium and Salmonella typhi.
Previous studies have shown that inactivation of the MutS or MutL mismatch repair enzymes increases the efficiency of homeologous recombination between Escherichia coli and Salmonella typhimurium and between S. typhimurium and Salmonella typhi. However, even in mutants defective for mismatch repair the recombination frequencies are 10(2)- to 10(3)-fold less than observed during homologous recom...
