Inoculation dose (c.f.u. per mouse) | 104 | 106 | 107 | 108 | 104 | 106 | 107 | 108 |
n = mice infected/total | 1/7 | 7/7 | 5/5 | 7/7 | 0/7 | 5/7 | 6/6 | 5/5 |
log10(c.f.u. per lung) (mean ± s.d.) | 0.9 ± 0.2 | 3.3 ± 0.9 | 3.6 ± 0.9 | 6.4 ± 0.7 | 0.8 ± 0.07 | 2.4 ± 1.1 | 4.0 ± 0.7 | 5.9 ± 0.7 |
CD1 mice (n = 5–7) were inoculated i.t. with increasing doses of WT or CV2 M. pneumoniae. At 4 d.p.i., the ratio of infected mice and the log10(c.f.u. per lung) (log10(mean ± s.d.)) were determined.
