Parasitic Burden

An unusually high mortality rate due to verminous (Philometra rubra) coelomitis was documented in wild-hatched striped bass Morone saxatilis raised in a fish hatchery as part of a stock restoration program. To decrease the parasitic burden and therefore potentially minimize mortality, the effectiveness of 2 different anthelmintics was evaluated. Two trials were conducted on wild-collected fingerlings naturally infected by P. rubra. In 2006, 144 yearling fish were randomly assigned to 4 experimental groups: (1) levamisole (Levasol®) at 2 mg l-1 via immersion for 8 h once weekly for 3 wk; (2) levamisole at a dose of 2.5 mg kg-1 biomass via feed once daily for 7 d; (3) emamectin benzoate (Slice®) at a dose of 0.05 mg kg-1 biomass via feed once daily for 7 d; and (4) control. Emamectin successfully eliminated live nematodes in 84.9% of the fish, whereas the administration of levamisole, either via immersion or feed, was not successful in significantly reducing the number of live P. rubra. In 2007, the administration of the same dosage of emamectin to approximately 1000 naturally infected yearling striped bass was associated with a 100% mortality rate of P. rubra in the 30 fish randomly examined 5 wk after the beginning of the treatment. Results of these trials indicate that, at the dosage used, the administration of emamectin at the end of the summer is safe for striped bass yearlings and considerably reduces the prevalence and intensity of the infection by this parasite.

ABSTRACT In a study of 173 pregnancies in 130 diabetic mothers of White's groups B, C and D who had received long-term treatment during pregnancy, the authors found cases of diabetes – in addition to the mother – in the maternal family, in the father and his family, or in the maternal as well as paternal family in a total of 100 pregnancies (57 %). The perinatal mortality was only slightly – and not significantly – higher among infants whose families included other diabetics than the mother. This higher mortality was found only among male infants of whom there was a preponderance in pregnancies with familial diabetes, but this was also not statistically significant. Thus, the result indirectly indicates that the primary cause of the high mortality among the infants of diabetic women must be the fact that the foetus develops in a diabetic environment.
