Phylogenetic relationships within the genus Steinernema (Nematoda: Rhabditida) as inferred from analyses of sequences of the ITS1-5.8S-ITS2 region of rDNA and morphological features
The ITS rDNA data were found to be of little utility in resolving relationships between these clades, but were useful in studying relationships between species within certain clades.

A novel detection and quantification method was developed for soil nematodes using real-time polymerase chain reaction (PCR), and the technique was used to estimate numbers of two closely related species of entomopathogenic nematode, Steinernema kraussei and S. affine.

Nematode phylogeny and embryology
It is pointed out that three distinct patterns of early embryonic development reported for nematodes are in good agreement with this new classification, which could be more consistent with the natural nematode system than with the usual morphological criteria.
Neoalloionema tricaudatum gen. n., sp. n. (Nematoda: Alloionematidae) associated with a cyclophorid snail in Cuc Phuong Natural Park, Vietnam
A new nematode genus and species associated with terrestrial gastropods from Vietnam is described and illustrated and the nature of the association between N. tricaudatum gen. n.
Angiostoma kimmeriensis sp. n. and Agfa tauricus sp. n. - parasitic Rhabditida (Nematoda) from Crimean terrestrial molluscs.
Comparative phylogenetic informativity of single ribosomal cluster regions in freshwater horsehair worms (Gordiacea, Nematomorpha)
The informativity of some regions of the ribosomal cluster (rDNA) in freshwater horsehair worms (Nematomorpha) has been analyzed to trace the nucleotide differences for discrimination of species and…
