Description
Summary:A new species of hemoflagellate is described from the blood of marine fishes of northern New England. This appears to be the first record of a biflagellate organism in the blood of marine fishes from the Western Hemisphere. The parasite, placed in the genus Cryptobia Leidy (Trypanoplasma, Laveran and Mesnil), differs morphologically from Trypanoplasma parmae Mackerras and Mackerras (1925), the only other named cryptobiid from the blood of marine fishes (Parma microlepsis from Australia) and also from Trypanoplasma borreli Laveran and Mesnil (1901) found in the blood of several species of freshwater fishes. The organism is named Cryptobia bullocki, sp. n. Cryptobia bullocki has been found in the blood of the winter flounder (Pseudopleuronectes americanus (Walbaum); smooth flounder (Liopsetta putnami) (Gill); mummichog (Fundulus heteroclitus Linnaeus); and striped killifish (F. majalis Walbaum). Attempts were unsuccessful to transmit the flagellate to mice (Mus musculus Linnaeus); goldfish (Carassius auratus Linnaeus); frogs (Rana pipiens Schreber); mullet (Mugil cephalus Linnaeus); brook trout (Salvelinus fontinalis Mitchill); tomcod (Microgadus tomcod Walbaum); and the grubby (Myoxocephalus aeneus Mitchill).
