Mycobacterium tuberculosis Complex in Remains of 18th–19th Century Slaves, Brazil

Obtained sequences were aligned and analyzed by using Bioedit software (Ibis Biosciences, Carlsbad, CA, USA) and ClustalW version 2.0.10 (www.ebi.ac.uk/clustalw). DAMBE (http://dambe.bio.uottawa. ca/dambe.asp) and MEGA (www. megasoftware.net) software were used to obtain similarity percentages among analyzed sequences. To characterize Rickettsia spp., we used nucleotide sequence identity to ref...
