Drug resistance and population structure of Mycobacterium tuberculosis Beijing strains isolated in Poland
Journal Title: Polish Journal of Microbiology - Year 2015, Vol 64, Issue 4
Abstract
In total, 1095 [i]Mycobacterium tuberculosis[/i] clinical isolates from 282 patients with drug-resistant and 813 with drug-sensitive tuberculosis (TB) in Poland during 2007–2011 were analysed. Seventy-one (6.5%) of the patients were found to have strains of Beijing genotype as defined by spoligotyping. The majority of patients were Polish–born; among foreign-born a large proportion came from Asia. Analysis showed strong associations between Beijing genotype infection and MDR, pre-XDR and XDR resistance, with a considerable relative risk among new patients, suggesting that this is due to increased spread of drug-resistant strains rather than acquisition of resistance during treatment.
