Sensitivity testing of H influenzae isolates revealed a resistance rate of 26% for ampicillin and 7% for chloramphenicol. The epidemiological findings in this study provide reasonable guidelines for empiric antibiotic therapy and also support the need to seriously consider vaccine prophylaxis in Jamaican children.....
