Q: Question: Does whole genome sequencing reveal mycobacterial microevolution among concurrent isolates from sputum and blood in HIV infected TB patients?
Answer: Among HIV-infected patients with poor cellular immunity, infection with multiple strains of M. tuberculosis was found in half of the patients. In those patients with identical strains, whole genome sequencing indicated that M. tuberculosis intra-patient microevolution does occur in a few patients, yet did not reveal a consistent direction of spread between sputum and blood. This suggests that these compartments are highly connected and potentially seed each other repeatedly.

A:
yes
