Abstract: A total of 78 samples of street foods from diﬀerent states in Malaysia were examined for the presence of Klebsiella pneumonia. K. pneumonia contamination was recorded in 32% of the samples examined. The frequency of the K. pneumonia isolates containing plasmids was shown to be 48%. Susceptibility testing showed that all isolates were highly resistant to ampicillin (100%), erythromycin (100%),rifampicin (100%), streptomycin (96%) and sulfamethoxazole (80%), but susceptible to chloramphenicol. RAPD proved to be the most eﬀective technique in discriminating the K. pneumonia isolates since dendrogram constructed using the combination of 4 primers could diﬀerentiate 25 isolates of K. pneumonia to 25 strains. This is the ﬁrst report that revealed the occurrence of K. pneumonia in street foodssold in Malaysia.
