[Phage typing of Mycobacterium tuberculosis strains coming from Nicaragua (preliminary report)]. / Fagotipaje de cepas de Mycobacterium tuberculosis procedentes de Nicaragua (reporte preliminar).

Fifty Nicaraguan strains of Mycobacterium tuberculosis were classified with a scheme of 9 specific phages. A preliminary distribution of characteristic phagotypes of the area is reported, with prevalence of phagotype I (intermedial) (66%), presence of phagotype A (34%) and absence of the rest of the types. Inclusions of phagotypes Bo4 and F-o-WJ within the classification scheme, as well as practical usefulness of the technique in studies directed to disease control, are valued.

[Study using phagetype markers of Mycobacterium tuberculosis strains from Ethiopia. A preliminary study]. / Estudio mediante marcadores fagotipicos de cepas de Mycobacterium tuberculosis procedentes de Etiopia. Estudio preliminar.

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.
