| pathology of pentastomid infections (sebekia mississippiensis) in fish. | differential pathogenesis was observed in two species of fish naturally infected with the pentastome sebekia mississippiensis. mosquitofish (gambusia affinis) showed a mild inflammatory response to developing nymphs, whereas swordtails (xiphophorus helleri) had an extensive granulomatous inflammatory reaction with accompanying hemorrhage, myositis, and myodegeneration. this suggested that certain species of tropical fish reared in the southeastern united states may be at risk to potentially harm ... | 1987 | 3682099 |
| monogenic inheritance of cyclodiene insecticide resistance in mosquitofish, gambusia affinis. | certain populations of the mosquitofish, gambusia affinis, developed high levels of resistance to endrin and other cyclodiene insecticides as a result of inadvertent exposure to agricultural sprays. genetic crossing studies show that endrin resistance is inherited as a single, autosomal, intermediate gene. | 1986 | 3755403 |
| laboratory evaluation of gambusia affinis fish as predators of the schistosome-bearing snails bulinus truncatus. | in this laboratory-based study involving numerous experiments, it was demonstrated that the mosquito fish gambusia affinis preys effectively upon the schistosome-bearing snail bulinus truncatus, even in the presence of an alternative source of food. egg masses and juvenile snails less than or equal to 2 mm in size are preferred. individual eggs are nibbled, and the tiny snails with fragile shells are swallowed and digested. in the absence of other foods, the fish consume the flesh of snails 3 to ... | 2012 | 3755766 |
