title: Correlation of phospholipase A & enterotoxin production by Salmonella typhimurium with reference to virulence parameters.
abstract: Seventy strains of S. typhimurium along with 10 strains each of S. typhi and S. paratyphi B, 3 strains of S. enteritidis and 2 strains of S. senftenberg were examined for phospholipase A (PLA) activity. S. typhimurium positive for PLA activity (17.14%) were subjected to study of other virulence parameters like enterotoxin production, haemolytic activity, surface hydrophobicity and antibiotic sensitivity. A high degree of correlation was observed between PLA activity and enterotoxin production, antibiotic sensitivity and cell surface hydrophobicity respectively.
