“…In trials of Rappaport broth, Collard & Unwin (1958), Iveson, Kovacs & Laurie (1964), Hooper & Jenkins (1965) and Iveson & Kovacs (1967) demonstrated improved salmonella recoveries over both selenite and tetrathionate media. The medium was also found suitable for the isolation of the selenite and tetrathionate sensitive S. cholerasuis from pigs by , Riley (1970) andBeh (1971). On the other hand, Harvey & Price (1968) found Rappaport broth less suitable for the isolation of S. dublin and S. pullorum.…”

Strontium chloride enrichment broth was found to be comparable to Rappaport broth for the recovery of a wide range of Salmonella serotypes from man, animals, meat products and effluents. With the exception of cloacal samples from reptiles, both procedures were superior to selenite F.The performance of strontium chloride Mand selenite F enrichment was improved when effluent samples were incubated at 43 degrees C.Strontium chloride M and Rappaport enrichment were superior to selenite F for the isolation of Arizona species from reptiles.Strontium chloride B, strontium selenite and Rappaport broths were found suitable for the isolation of multiple Salmonella serotypes from sea water contaminated with abattoir effluents. The strontium chloride B and strontium selenite enrichment media were superior to Rappaport broth when samples were incubated at 43 degrees C.Modified bismuth sulphite agar was found superior to Salmonella-Shigella agar as a solid subculture medium.The investigation of a food poisoning outbreak due to Salmonella typhimurium phage type 21 is reported.The significance of the choice of sampling and isolation techniques in salmonellosis in man and animals is discussed.

Summary. Pregnant sows were immunized either intramuscularly or intramammarily with a killed E. coli vaccine. Sampies of blood and mammary secretion were assayed for antibody to E. coli eells and E. coh enterotoxin. The assoeiation of each class of inununogloimlin with antibody to the Inieterial cells was also estimated. It was found that immunization by either method increased direct agglutination titres and antiglohulin enhaneement titres in serum and mauimary secretion. There were no major differences in these parameters het\veen the two groups of sows. In serum and mammary secretion from Ijoth groups of sows IgG was quantitatf\'ely the most important class of immunoglobulin associated with antibody to E. coli cells. Immunization had the eflect of increasing tiie percentage of IgC; and IgM associated with antibody in lilood serum from about 5t o about 20%. In contrast, the percentage of IgA in serum with antibody activity against £. coli was around 20^ prior to immunization and did not alter significantly after immunization. Sampies of IJIOOC! and mammary secretion from sows immunized iiitramammariiy were more effective in neutraiizing E. eoU enterotoxin than corresponding samples from sows iuununized intramusculariy; the biologieai significance of this finding is at present uiicertaiu.INTRODUCTION.
