Members of the genus Habronema (Nematoda: Habronematidae) were preserved in 4 fixatives for examination with scanning electron microscopy (SEM). Tegumental features of the anterior and posterior extremities of these specimens were compared to evaluate the effect of the fixatives: modified Flemming's solution, glutaraldehyde (GA), Karnovsky's fixative and 70% ethanol. Fixatives were assessed on ...

This study describes the first record of Bourgelatia diducta (Nematoda: Chabertiidae) from wild boars in the Republic of Korea (=South Korea). Gastrointestinal tracts of 87 Korean wild boars (Sus scrofa coreanus) hunted in mountains in the south-western part of South Korea between 2009 and 2012 were examined for their visceral helminths. B. diducta, as identified by morphological characteristic...

The complete genome sequence of the free-living nematode Caenorhabditis elegans was published 4 years ago. Since then, we have seen great strides in technologies that seek to exploit this data. Here we describe the application of some of these techniques and other advances that are helping us to understand about not only the biology of this important model organism but also the entire phylum Ne...

Mermithid parasites (Nematoda: Mermithidae) were observed in 11 mosquito species in 22 counties of Indiana, Michigan, Minnesota, Ohio and Wisconsin. Natural hosts included adult Aedes vexans, Ae. canadensis, Ae. cinereus, Ae. diantaeus, Ae. punctor, Anopheles punctipennis and Coquillettidia perturbans and larvae of Ae. abserratus, Ae. canadensis, Ae. cinereus, Ae. communis, Ae. diantaeus, Ae. p...

Caenorhabditis elegans (C. elegans), a member of the phylum Nematoda, carries the evolutionarily conserved genes comparing to mammals. Due to its short lifespan and completely sequenced genome, C. elegans becomes a potentially powerful model for mechanistic studies in human diseases. In this mini review, we will outline the current understandings on C. elegans as a model organism for microRNA (...

This paper describes some morphological aspects of Cylicocyclus brevicapsulatus (Ihle, 1920) (Nematoda: Cyathostominae) from Equus caballus in Brazil. The worms were studied using an optical microscope (measurements and illustrations) and a scanning electron microscope for a more detailed examination of the external morphology. The buccal capsule is very short, with a very thin wall, and the do...

Major sperm proteins (MSPs) are a nematode-specific system of cytoskeletal required for amoeboid movement. A number MSP genes vary in different nematode species, but encoded protein sequences reveal high homology between these proteins. However, all studies localization and functions to date based exclusively on the representatives order Rhabditida belonging class Chromadorea, while MSP-driven ...
