TABLE 1.

Comparison of lung bacterial burdens obtained for infections with a M. africanum clinical isolate versus M. tuberculosis reference strains HN878 and H37Rv.

	Low dose		High dose
	Log₁₀CFU		Log₁₀CFU
	d30	d60	d30	d60
M. africanum (L6)	2.62 ± 0.022	2.45 ± 0.021	3.012 ± 0.129	2.89 ± 0.068
Mtb HN878 (L2)	6.078 ± 0.087	5.723 ± 0.110	7.453 ± 0.138	–
Mtb H37Rv (L4)	4.866 ± 0.0898	5.024 ± 0.296	–	5.203 ± 0.314

C57BL/6 mice were infected via aerosol with a low (<200 CFU) or high dose (>500 CFU) of the indicated bacteria and on day 30 or 60 post-infection the lungs were collected and the bacterial burden determined by CFU enumeration. Data are shown as mean ± SEM from at least five animals per time point. Mtb, M. tuberculosis; L, lineage.
