Dirofilaria cancrivori sp. n. (Nematoda: Filarioidea from the crabdog, Procyon cancrivorus, in Guyana.

Dirofilaria cancrivori sp. n. is described from subcutaneous tissues of the crabdog, Procyon cancrivorus, in Guyana, South America. The filarid is morphologically distinct from Dirofilaria tenuis, parasite of a related host, the raccoon, in the southern United States, and all other species of Dirofilaria. The parasite can be distinguished from other dirofilarias based on a combination of morphological features including its size, number, and arrangement of caudal papillae on the male tail, size and shape of the spicules, the presence of longitudinal ridges and transverse striations on the cuticle, and the microfilaria.

Dirofilaria macrodemos and D. panamensis spp. n. (Nematoda: Filarioidea) from Central and South Americal sloths.

Two new species of Diorfilaria, Dirofilaria macrodemos and Dirofilaria panamensis, are described from the subserosa of Central and South American sloths. Dirofilaria macrodemos, described from the three-toed sloth, Bradypus tridactylus, in Guyana, is characterized and differentiated from other dirofilarias by its length (female 214mm, male 64mm), relatively long tail (female 140 micron, male 110 micron), and the number and distribution of the caudal papillae (7 pairs) in the male. Dirofilaria panamensis, parasite of the two-toed sloth, Cholopeus hoffmanni, in Panama, was previously described as Dirofilaria incrassata by Caballero (1947), but can be distinguished from both D. macrodemos and D. incrassata on the basis of body size (female 66 mm long by 360 micron wide, male 34 mm long by 250 micron wide), tail length (female 80 micron, male 80 micron), and number (6 pairs) of caudal papillae in the male.

Brugia lepori sp. n. (Filarioidea: Onchocercidae) from rabbits (Sylvilagus aquaticus, S. floridanus) in Louisiana.

Brugia lepori sp. n., a filarial nematode from the abdominal lymphatics and subcutaneous tissues of rabbits (Sylvilagus aquaticus, S. floridanus), from St. Tammany Parish, Louisiana, is described. Brugia lepori is of moderate size (males 12 to 19 mm, females 39 to 45 mm) and within the genus most closely resembles Brugia beaveri of the raccoon, from which it can be distinguished by its larger size, smaller spicules, and smaller microfilaria which has a shorter cephalic space. Brugia lepori is only the second species of Brugia described from North America and the third species reported from the Western Hemisphere.

Effect of anthelmintics on the enzyme activities of Setaria cervi (Nematoda: Filarioidea).

The present study deals with the comparative efficacy of Hetrazan, levamisole and tetramisole on the enzyme activities of adult Setaria cervi worms. The drugs were administered orally to white rats, intraperitoneally infected with the bovine filariid, Setaria cervi. Biochemical assays revealed the decreased activities of glucose-6-phosphatase, fructose-1,6-diphosphatase, lactate dehydrogenase and adenosine triphosphatase in the drug-treated worms. Hetrazan was relatively more effective than tetramisole and levamisole. A possible role of these enzymes in the energy supply and survival of the worm has been briefly discussed.
