Phage typing of Salmonella enteritidis in the United States.

摘要: The number of reported isolates Salmonella enteritidis has increased dramatically in the last 10 years. For many years phage typing been a useful epidemiologic tool for studying outbreaks S. typhi and typhimurium. In 1987, Ward et al. (L. R. Ward, J. De Sa, B. Rowe, Epidemiol. Infect. 99:291-294, 1987) described scheme enteritidis. This system differentiated 27 types by use phages. With these phages, we typed 573 strains from humans (42 outbreaks), animals, food, environment. Ninety-six percent were typeable. most common 8 (48.2%), 13a (20.1%), 13 (7.8%), 14b (7.8%). Most specifically collected egg-related northeastern United States 1988 1989, probably accounting distribution four this sample. was particularly differentiating group animal that had diverse types. 49 typed, 16 different patterns obtained. Phage type represented 32% strains, but no other more than 8% strains. One-half poultry. will be comparing found with those encountered worldwide determining whether virulent 4 are entering States. Additional systems as well molecular techniques being studied to determine they can differentiate 13a.
