In-vitro sensivity of salmonella & shigella to six antibiotics

ABSTRACT

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.
