An Outbreak of Food Poisoning by Salmonella senftenberg / 감염

ABSTRACT

Salmonella senf tenberg is an uncommon serotype and was first isolated in 1928. Recently, its increasing rate of isolation from human sources, especially from infants and neonates in hospital environments, has suggested it as an important pathogen in other countries. It has been isolated sporadically from the stool of patients with diarrhea but there has been no report of outbreak by S. senf tenberg in Korea. We report an outbreak by S. senf tenberg affecting 104 patients. S. senf tenberg was isolated from pork meat left for a long time at room temperature. The incubation period was 9 to 12 hours. Predominant symptoms were diarrhea (90%), fever (74.4 %), abdominal pain (55.1%), nausea (42.2%), and vomiting (28.9%). Mean peripheral leukocyte count was 11,413 (+/-3,037)/mm 3 and 82 (+/-9.8) % of neutrophils were of segmented form. S. senf tenberg was isolated from the stool of 31 patients among 90 patients. Most of the patients improved within 2 to 5 days with quinolone and intravenous fluid therapy.
