[Study using phagetype markers of Mycobacterium tuberculosis strains from Ethiopia. A preliminary study].

Twenty strains of Mycobacterium tuberculosis from Addis Ababa (Ethiopia) are studied by means of the phage typing technique in mycobacteria. The results obtained show the preliminary distribution of phage types belonging to type I (intermediate) and absence of the remaining types. The lysis pattern of autochthonous M. tuberculosis is characterized by a prevalence of sensitivity to phages DS6A, GS4E, BG1, and D34. The early results of sensitivity obtained with phage Bo4 and its assessment within the current scheme for M. tuberculosis classification.
