Abstract
Bacterial pathogens either hide from or modulate the host's immune response to ensure their survival. Photorhabdus is a potent insect pathogenic bacterium that uses entomopathogenic nematodes as vectors in a system that represents a useful tool for probing the molecular basis of immunity. During the...

Cold Spring Harbor Protocols (2010)11 2010
Abstract
We describe a method for culturing P. murrayi extracted from soil and sediment samples from the McMurdo (MCM) Dry Valleys of Antarctica. Nematodes are cultured on sand agar plates and incubated at various temperatures, and feed on bacteria growing on the agar media. They can be subcultured and store...

Abstract
The genus Plectus is one of the most widely distributed and common nematode taxa of freshwater and terrestrial habitats in the world, and is of particular interest because of its phylogenetic position relative to the origin of the Secernentean radiation. Plectus murrayi, a bacteria-f...

Abstract
We suggest here that the anatomy of the fish digestive tract and especially that of the stomach plays an important role in host suitability for H. spinigera. While P. excavatum is the only intermediate host in Lake Waihola, H. spinigera was found in six different fish species: Aldrichetta forsteri,...

Abstract
We have characterized SL RNAs from Prionchulus punctatus. Surprisingly, this revealed the presence of a set of SLs that show clear sequence similarity to the SL2 family of spliced leaders, which have previously only been found within the rhabditine group (which includes C. elegans). Expression of on...

Our investigation of spliced leader trans-splicing in distantly related Dorylaimia nematodes indicates that spliced-leader trans-splicing arose before the nematode phylum and suggests that the spliced leader RNA gene complements in extant nematodes have evolved from a common ancestor with a diverse...

Abstract
Intestinal helminthiases are infections in which adult helminths (nematodes, trematodes, cestodes) parasitize the intestine. In Central Europe intestinal helminthiases are usually acquired during travel or are imported by migrants. In contrast, in developing countries, intestinal helminthiases are h...

Abstract
We argue that a well chosen gene name can concisely convey a wealth of relevant biological information. A consistent nomenclature adds transparency that can have a real impact on our understanding of gene function. Currently, genes in parasitic nematodes are often named ad hoc, leading to confusion...
