High initial multidrug-resistant tuberculosis rate in Buenaventura, Colombia: a public-private initiative.
Abstract
From the total of 73 MDR-TB isolates, DNA could be extracted from 68 (93.1%). Among 10 genotypes identified, a specific Beijing family genotype SIT190 represented a cluster of 22 cases (20 from Buenaventura). Eight of 20 Beijing strains were involved in a cluster of new cases, suggesting recent ongoing transmission.
