background : cats play a crucial role in the epidemiology of gastrointestinal helminthic parasites and also play a major role in transmitting of these parasites through faecal contamination of soil, food or water. the aim of this study was to determine the species of gastrointestinal helminthes parasites in stray cats from a rural area of bandar-e-anzali, iran. method: gastrointestinal helminth...

A new species of nematode, Pterygodermatites (Pterygodermatites) mexicana n. sp., is described based on specimens recovered from the intestine of the gray sac-winged bat, Balantiopteryx plicata (Chiroptera, Emballonuridae), from the Biosphere Reserve "Sierra de Huautla" in the state of Morelos, Mexico. This is the second species in the genus described from bats in the New World, since most of t...

Pterygodermatites ( Paucipectines ) hymanae n. sp. (Rictulariidae) collected from the Incan shrew opossum, Lestoros inca , from Peru is described herein. These nematodes show a subapical, slightly dorsal oral opening and a laterally compressed buccal capsule with 2 conspicuous lateral walls and a dorsal wall. Each lateroventral wall possesses 4 relatively large denticles, and the dorsal wall ha...

The mosquito control potential of the mosquitofish and Bacillus thuringiensis var. israelensis (Bti) were evaluated in experimental wild rice fields in Lake County, California. Fields were assigned one of six treatment: control, 1.1 kg/ha G. affinis, 3.4 kg/ha G. affinis, Bti only (6 kg/ha Vectobac granules), 1.1 kg/ha G. affinis plus Bti and 3.4 kg/ha G. affinis plus Bti. Gambusia affinis, at ...

Field studies demonstrated a 21.3% prevalence of Pterygodermatites coloradensis in Peromyscus leucopus and a decreasing mean worm burden during the October to April, 1977-79, study period. Decreasing worm burden may be due to fewer available infested intermediate hosts, the short life span of adult worms, or both. Forest and cave salamanders are probably not effective transfer hosts of P. color...

In a parasitological survey of free-ranging Cerdocyon thous (Carnivora: Canidae) from Brazilian Caatinga shrubland, a new species of Pterygodermatites (Multipectines) was recovered from the small intestine of this host. Morphological analysis showed that P. (Multipectines) pluripectinata n. sp. is distinguished from all other congeneric species mainly by the numerous plate-like projections and ...
