Numbers of rats showing visual signs of morbidity after tail vein injection with predatory bacteria
| Treatment | No. of rats showing visual signs of morbidity at indicated time after inoculation/total no. of rats | ||||
|---|---|---|---|---|---|
| 2 h | 4 h | 18 h | 20 d | 20 d* | |
| Control (PBS) | 0/12 | 0/12 | 0/12 | 0/12 | 0/12 |
| B. bacteriovorus 109 J | 0/12 | 0/12 | 0/12 | 0/12 | 0/12 |
| M. aeruginosavorus ARL-13 | 0/12 | 0/12 | 0/12 | 0/12 | 0/12 |
| K. pneumoniae a | 0/7 | 0/7 | 1/7 | ||
*Rats were inoculated a second time at 10 days post-infection to model a multiple bacteremia event. aWith animal well-being in mind, rats inoculated with K. pneumoniae were not kept past 18 h post-inoculation.
