Comparative survey of early embryogenesis of Secernentea (Nematoda), with phylogenetic implications

Canadian Journal of Zoology, 2001
Insight into the evolution of class Secernentea (Nematoda) for the purpose of providing a phylogenetic context for the model Caenorhabditis elegans is being gained from the use of molecular character sets. Such phylogenies provide a framework for mapping the evolution of diversity in some early-development characters for 70 species and 19 families of ...

The mitochondrial genomes of the human hookworms, Ancylostoma duodenale and Necator americanus (Nematoda: Secernentea)

International Journal for Parasitology, 2002
The complete mitochondrial genome sequences were determined for two species of human hookworms, Ancylostoma duodenale (13,721 bp) and Necator americanus (13,604 bp). The circular hookworm genomes are amongst the smallest reported to date for any metazoan organism.

New record of Ascaridia nymphii (Secernentea: Ascaridiidae) from macaw parrot, Ara chloroptera, in China

Parasitology International, 2018
Present study was performed to identify the species of ascarids from macaw parrot, Ara chloroptera, in China. Total 6 ascarids (3 males and 3 females) were collected in the feces of 3 macaws at Guangzhou Zoo in Guangdong Province, China. Their morphological characteristics with dimensions were observed under a light microscope, and their genetic ...

Ribosomal DNA and Phylogeny of the Ascaridoidea (Nemata: Secernentea): Implications for Morphological Evolution and Classification

Molecular Phylogenetics and Evolution, 1998
Nematodes of the superfamily Ascaridoidea are parasites of the alimentary tract of vertebrates and include species that are of medical and economic importance. Existing evolutionary hypotheses for these organisms have frequently been based on interpretation of one or few "key" structural or life history features.

Phylogenetic Analysis of rDNA Sequences from Adenophorean Nematodes and Implications for the Adenophorea-Secernentea Controversy

Invertebrate Biology, 1998
Phylogenetic relationships of 13 adenophorean and 15 secementean nematodes were analyzed using morphological data and 18S rDNA sequences in parallel. Both data sets strongly supported monophyly of Adenophorea and Secerentea. Monophyly of the subfamily Stilbonematinae which is remarkable for symbiosis with bacteria-was also confirmed. Three taxa without

The association of two Diplogasteroides species (Secernentea: Diplogastrina) and cockchafers (Melolontha spp., Scarabaeidae)

Nematology, 2001
AbstractThe life cycle of two morphologically very similar Diplogasteroides species and their association with cockchafers in southern Germany was investigated. 70-100% of cockchafer grubs and 95% of the imagines carried Diplogasteroides spp. dauer juveniles. The nematodes were almost exclusively found on the external cuticle of the insects and usually

Ultrastructure of the postcorpus of the esophagus of Teratocephalus lirellus (Teratocephalida) and its use for interpreting character evolution in Secernentea (Nematoda)

Canadian Journal of Zoology, 2001
The ultrastructure of the postcorpus of the putative outgroup of Secernentea (Nematoda), Teratocephalus lirellus (Teratocephalida), is compared with previous observations of representative species Zeldia punctata (Cephalobina), Caenorhabditis elegans (Rhabditina), and Diplenteron sp.
