Sewage effluent: likely source of Salmonella enteritidis, phage type 4 infection in a commercial chicken layer flock in southern California.
Following the diagnosis of Salmonella enteritidis, phage type 4, infection in a commercial layer flock in southern California, effluent from a nearby sewer treatment plant was investigated as a potential source of infection. Between July 1994 and March 1995, 68 Salmonella isolations, comprising 27 serotypes, were made from the inflow (raw sewage) and effluent (treated sewage). Thirty-nine of 68...
متن کاملSalmonella enteritidis, phase type 4 infection in a commercial layer flock in southern California: bacteriologic and epidemiologic findings.
Salmonella enteritidis, phage type 4 (SE PT4), was isolated from five of six 27-wk-old layer chickens submitted for necropsy from a flock of 43,000. Bacteriologic and epidemiologic investigations on the ranch revealed that five of the eight flocks (n = 176,000) were infected. The prevalence of SE PT4 in randomly selected healthy birds ranged from 1.7% (in caged birds) to 50% (in free-range bird...
متن کاملSalmonella enteritidis phage types 1 and 4: pheno- and genotypic epidemiology of recent outbreaks in Finland.
In the 1990s, Salmonella enterica subsp. enterica serovar Enteritidis has caused 15 outbreaks in Finland; 12 of them were caused by phage type 1 (PT1) and PT4. Thus far, there has been no clear evidence as to the source of these Salmonella Enteritidis PT1 and PT4 strains, so it was necessary to try to characterize them further. Salmonella Enteritidis PT1 (n = 57) and PT4 (n = 43) isolates from ...

متن کاملPreliminary Report SALMONELLA ENTERITIDIS PHAGE TYPE 4 IN ONTARIO
Salmonella enteritidis (SE) is one of the most common Salmonella serotypes causing human morbidity and mortality(1). The increasing prevalence of SE has been noted in various countries worldwide(2,3), including a 13-fold increase in human isolates in the United Kingdom between 1981 and 1987(1), and an 8-fold increase (0.5 to 3.9 per 100,000) in the United States between 1976 and 1994; in the Un...
