Gongylonematid nematodes (Nematoda: Gongylonematidae) parasitic in some Australian vertebrates are described from the monotypic genus Gongylonema (Gongylonema) (Molin, 1857). Three previously incompletely described species from a megapod and murid rodents are re-described from limited material....

Objective: This research was carried out to determine the digestive and respiratory system helminths of domestic geese collected from Canik, Çarşamba, Havza, Kavak, Terme, and Tekkeköy districts representing Samsun province. Methods: Within the scope of the study, the digestive and respiratory...

During a parasitological survey, specimens belonging to the genus Hedruris (Nematoda: Hedruridae) were found in the stomach of Synbranchus marmoratus Bloch from the Paraná Guazú River, Paraná River basin (Argentina). Comparative morphological studies with its congeners showed that these nematodes...

The cosmopolitan genus Streptocara Railliet, Henry and Sisoff, 1912 (Nematoda: Acuariidae) comprises parasites of the upper alimentary tract of aquatic and, rarely, terrestrial birds. Two species of the genus Streptocara are redescribed from Bulgaria by means of light and scanning electron...

Background: Although wild ungulate populations are heavily monitored throughout Europe, we understand little of how parasites affect population dynamics, and there is no systematic, long-term monitoring of parasite diversity and parasite loads. Such monitoring is in part hampered by a lack of time- ...

Nematodes of the genus Contracaecum Raillet & Henry, 1912 (Anisakidae, Contracaecinae) have a worldwide distribution. The taxonomy of the genus Contracaecum is well-known nowadays due to several morphometric studies, scanning electron microscopy, and molecular biology. The aim of this work was...

In this paper we re-describe Trichuris muris based on morphological data following isolation from two commensal rodent species, Mus musculus from Mexico and Rattus rattus from Argentina. Furthermore, we provide a molecular characterization based on mitochondrial (cytochrome c oxidase subunit 1...

A new species of Spirocamallanus Olsen, 1952 (Camallanidae), is described based on specimens found parasitizing Propimelodus eigenmanni (Siluriformes), an Amazonian fish. The new species has buccal capsule with 15-19 spiral ridges, males with caudal alae supported by 3 pairs of precloacal and 6...

Baylisascaris transfuga (Rudolphi, 1819) is a common parasitic nematode in the digestive tract of various species of bears worldwide, with great veterinary significance. However, our present knowledge on the morphology of B. transfuga remains insufficient. In the present study, the detailed...

Nematodes of the family Molineidae are the most frequent helminths reported infecting the digestive tract of South American amphibians. The molineid genus Kentropyxia Baker, 1982 includes only 2 nominal species of parasitic nematodes: Kentropyxia sauria Baker, 1982 and Kentropyxia hylae Feitosa et...
