Abstract

Analysis of Mycobacterium tuberculosis strains was carried out using isolates collected from 69 Senegalese and 20 Ivory Coast tuberculosis patients. These 89 isolates were typed by means of the spoligotyping technique, showing clusterized populations of bacterial strains. In the Senegalese patients, 35 genetic profiles were observed with 10 clusters of spoligotypes from 44 isolates. Among Ivory Coast patients, 11 spoligotypes were found for 20 isolates. A particular cluster of isolates was evident both in Senegalese (10) and Ivory Coast (11) patients. These results show the existence of polymorphism of the direct repeat region for African M. tuberculosis strains. However they suggest that additionnal markers are needed for accurate epidemiological studies in areas that are highly endemic for tuberculosis.
