Abstract
The ability of three strains of Listeria monocytogenes NCTC 7973, sero var 1/2a, NCTC 5124m serovar 4a, C-274 serovar 4b and one strain of L. seeligeri (SLCC 3954) to grow in TPB (Tryptose phosphate agar) at pH values between 5-9 and produce haemolysin has been investigated at two incubation temperatures. The minimum and maximum pH values at which h aemolysin was detected were 5 and 9 respectively, at 20-degrees and 32 -degrees-C.
