Mean and standard deviation (std) of different clinical variables in Ehrlichia phagocytophila infected lambs. The lambs were inoculated with E. phagocytophila infected blood when they were 12–14 days old and 6–8 months old, respectively.
Age | N | Incubation period (days) | Max. temperature (°C) | Duration of fever (days)** | Magnitude of fever (mm2)* | Infected neutrophils (109 litre-1) (day 6) | Numbers of neutrophils (109 litre-1) (day 14)** |
12–14 days | 6 | 4.0 ± 0.58 | 41.40 ± 0.141 | 4.3 ± 1.11 | 364 ± 102 | 1.35 ± 0.853 | 0.68 ± 0.154 |
6–8 months | 14 | 4.3 ± 0.60 | 41.62 ± 0.204 | 8.6 ± 2.02 | 702 ± 232 | 1.51 ± 0.590 | 0.31 ± 0.061 |
