Recent genotyping studies of Mycobacterium tuberculosis (Mtb) in Ethiopia have reported the identification of a new phylogenetically distinct Mtb lineage, lineage 7. We therefore investigated the genetic diversity and association of specific Mtb lineages with sociodemographic and clinical parameters among pulmonary TB patients in the Amhara Region, Ethiopia. DNA was isolated from Mtb positive sputum specimens (n=240) and analyzed by PCR/24-locus MIRU-VNTR and spoligotyping. Bioinformatics analysis assigned the Mtb genotypes to global lineages, and associations between patient characteristics and genotype were evaluated using logistic regression analysis. The study revealed a high diversity of modern and pre-modern Mtb lineages among which approximately 25% were not previously reported. Among the Mtb strains (n=138) assigned to seven sub-groups, the largest cluster belonged to the lineage Central Asian (CAS) (n=60; 26.0%), the second largest to lineage 7 (n=36; 15.6%), and the third to Haarlem (n=35; 15.2%). Four sub-lineages were new in the MIRU-VNTRplus database, designated NW-ETH3, NW-ETH1, NW-ETH2, and NW43 ETH4 which included 24 (10.4%), 18 (7.8%), 8 (3.5%) and 5 (2.2%) isolates, respectively. Notably, patient delay was significantly longer among patients infected with lineage 7 strains (Mann-Whitney test p

Dear Amar and Dr Lawrence,thank you for citing relevant articles.Incidentally,I am aware of the Ethiopian studies,but not that from the US.

Yes, Lineage 7 has been identified outside of Africa. We have them from patients in Europe. but they are all immigrants from Africa.

Thank you dear Faramarz for your response.
