Phospholipase A production by isolates of Salmonella species.
The incidence of intra- and extra-cellular phospholipase-A production by Salmonella isolates from human, poultry and environmental material was investigated. Nearly 17 per cent (15/90) of the strains tested produced phospholipase A. Phospholipase production was encountered in S. typhi, S. paratyphi A, S. typhimurium, S. seftenberg, S. bareilly, S. weltevredeen, S. newport, S. adelaide, S. alachua and S. gallinarum. Maximum (10/15) phospholipase producers were isolated from the human material. Phospholipase positive human isolates exhibited a high incidence of simultaneous multiple drug resistance, enterotoxigenicity and cell surface hydrophobicity.
