Natural bactericidal activity of human serum against strains of Campylobacter jejuni isolated in Lagos, Nigeria.

The sensitivity of Campylobacter jejuni strains LA4, LA12, LA36, LA53, LA1214, LA1308 and LA1309 constituting the most prevalent strains of C. jejuni isolated in Lagos, Nigeria to the bactericidal activity of normal human serum was determined using microtiter technique. Results obtained shows that only strains LA 36 and LA53 were serum resistant while others (strains LA4, LA12, LA1214, LA1308 and LA1309) were serum sensitive. This finding is important epidemiologically and is the first report on serum sensitivity of local isolates of C.jejuni in Nigeria.
