In-vitro sensivity of salmonella & shigella to six antibiotics

This study show that there is a multiple resistance to six antibiotics tested in- vitro by both salmonellae and shigellae organisms. Of note is the fact that 68.35 per cent of the salmonellae strains tested were resistant to chloramphenicol and 23-64 per cent were relatively resistant. It was shown that 90.13 per cent of salmonellae strains were sensitive to Kanamycin, whereas only 17.53 per cent of the strains were sensitive to chloramphenicol. However it should be borne in mind that laboratory tests have definite limitations. The in-vitro tests merely indicate that a bacterium is sensitive or resistant under strictly experimental conditions to certain levels of antibiotics.

Salmonella isolation from raw meat in Rangoon

Six hundred and ninety samples of raw meat collected from the slaughter house and markets of Rangoon were tested at the Bacteriology Section and Food and Drug Section of National Health Laboratory from June 1973 to July 1974. 63 salmonella of 9 different serotypes were isolated. Out of which S.anatum and S. derby are found to be the most frequent serotype all three kinds of raw meat. This is the first time salmonella from raw meat is reported.
