The results are in: Bacterial parasite strives for balance in host infection
...e researchers exposed a Daphnia clone to bacterial spores
and tracked individual host mortality. Infected Daphnia sustained far more casualties than either unexposed controls or exposed but uninfected individuals, with deaths beginning at 23 days old and ending at 74 days old. (The first control died at 96 ...
