Synlophe of Nematodirus neotoma (Trichostrongyloidea)

Journal of Parasitology, 1988
The synlophe of Nematodirus neotoma from Neotoma spp. is characterized. The cervical synlophe is composed of 30-32 and 36-42 ridges in males and females, respectively. Of these, 14 and 20-22 ridges are continuous in the cervical zone and extend to the base of the cephalic expansion.

The first phylogenetic reconstruction of Nippostrongylinae (Nematoda: Heligmonellidae) reveals 3 new genera, the polyphyletic nature of Carolinensis and Vexillata, and identifies 5 clades with varying associations with mammals [PDF]

Parasitology
The Nippostrongylinae is a group of strongylid nematodes that includes species typically associated with coprophagous mammals; in the New World, it is represented by 82 species within 11 genera.

The Synlophe and Other Structural Characteristics of Sarwaria bubalis (Nematoda: Trichostrongyloidea) from Cattle in Guyana

Journal of Parasitology, 1996
The synlophe (longitudinal, surface cuticular ridges) of Sarwaria bubalis is described for the first time. It is a tapering lateral synlophe of about 40 ridges. The synlophe of S. bubalis is similar to that of Ostertagia ostertagi but markedly different from that of species of Spiculopteragia and Mazamastrongylus.

Re-Evaluation of Mazamastrongylus dagestanica (Trichostrongylidae) with Descriptions of the Synlophe, Genital Cone, and Other Structural Characters

Journal of Parasitology, 1996
The synlophe of specimens of Mazamastrongylus dagestanica was characterized laterally and ventrally by a strongly tapering system of ridges in the cervical zone. This pattern, including the prominent system of "hood" ridges adjacent to the excretory pore and the absence of continuous subdorsal and subventral ridges is considered typical for the genus ...

Morphology of the synlophe and genital cone of Parostertagia heterospiculum (Trichostrongylidae) with comments on the subfamilial placement of the genus

Systematic Parasitology, 1992
The genus Parostertagia is referred to the Cooperiinae with reference to a suite of shared characters of the synlophe and genital cone postulated as derived homologies for the subfamily. The genus has traditionally been relegated to the Graphidiinae or Ostertagiinae, but unique structural attributes of the synlophe and genital cone indicate close ...

Heligmosomoides neopolygyrus Asakawa & Ohbayashi, 1986, a cryptic Asian nematode infecting the striped field mouse Apodemus agrarius in Central Europe [PDF]

Parasites & Vectors, 2014
Background Heligmosomoides polygyrus is a widespread gastro-intestinal nematode infecting wild Apodemus (wood mice) throughout Europe. Using molecular and morphological evidence, we review the status of Heligmosomoides from Apodemus agrarius in Poland ...

Redescriptions of Haemonchus mitchelli and Haemonchus okapiae (Nematoda: Trichostrongyloidea) and Description of a Unique Synlophe for the Haemonchinae

Journal of Parasitology, 2002
In the course of a revision of Haemonchus Cobb, 1898 (Nematoda), commonly referred to as large stomach worms, significant new morphological information was discovered that allows the recognition of 2 species believed for more than 50 yr to be synonymous. Both species, Haemonchus mitchelli Le Roux, 1929, from the eland Taurotragus oryx and other African

Developing novel anthelmintics from plant cysteine proteinases. [PDF]

Parasit Vectors, 2008
Intestinal helminth infections of livestock and humans are predominantly controlled by treatment with three classes of synthetic drugs, but some livestock nematodes have now developed resistance to all three classes and there are signs that human ...
