Effects of temperature shift on acid and heat tolerance in Salmonella enteritidis phage type 4.
The transfer of cells of Salmonella enteritidis phage type 4 from 20 to 37-46 degrees C resulted in marked increases in acid and heat tolerance. The former was maximized within 5 to 15 min of the shift and was largely independent of protein synthesis. In contrast, induction of increased heat tolerance was slower, requiring more than 60 min to be completed, and was prevented by inhibition of pro...
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...

متن کاملNatural or raw almonds and an outbreak of a rare phage type of Salmonella enteritidis infection.
In December 2000, an increase in the number of Salmonella enteritidis cases was reported in Ontario by the Ontario Central Public Health Laboratory. In January 2001, S. enteritidis isolates from Ontario for the months of November and December 2000, and January 2001, were submitted to the National Laboratory for Enteric Pathogens for phage typing. Several isolates of a rare phage type, PT30, wer...
متن کاملEmergence of Salmonella serotype Enteritidis phage type 4 in Hawaii traced to locally-produced eggs.
OBJECTIVES In August 1998, the Hawaii Department of Health observed a nine-fold increase in human Salmonella Enteritidis (SE) infections. Isolates were phage type 4 (PT4). An investigation was initiated to determine the source of the outbreak. METHODS A matched case-control study enrolled 38 cases. Cases were Hawaii residents with diarrhea and a stool culture yielding SE. RESULTS Eating egg...
