Table 2. Recovery of LVS and LVSΔ1423/1422 following co-inoculation into C57BL/6 micea.
Organ | CFU on BHICB | CFU on BHICB containing Kanamycin |
Liver | 1.0×105 | 0.00 |
Lungs | 1.9×107 | 0.00b |
Spleen | 1.3×107 | 6.1×102 |
Five mice were inoculated IN with a mixture of 5.9×103 CFU of LVS and 8.0×103 CFU of LVSΔ1423/1422. Five days PI the mice were euthanized, and tissue extracts were cultured on BHICB with or without Kan. The numbers shown represent the average CFU/g tissue.
A few colonies were isolated from the lungs of one of five mice.
