Dioctophyme renale (Nematoda: Dioctophymatoidea) in the abdominal cavity of Rattus norvegicus in Japan

open access: yesParasitology International, 2011
We collected 24 brown rats, Rattus norvegicus, in Kanagawa Prefecture in Japan and found one rat harboring a dioctophymatid nematode. A single male and a female worm were recovered from the abdominal cavity and were identified as Dioctophyme renale based on morphologic features and a BLAST DNA sequence analysis.

Morphological and Molecular Characterization of Larval and Adult Stages of Eustrongylides excisus (Nematoda: Dioctophymatoidea) with Histopathological Observations

open access: yesJournal of Parasitology, 2019
The genus Eustrongylides includes nematodes known as the etiological agent of the "big red worm disease." The aim of this work was to identify Eustrongylides spp. larvae from fish and adults from great cormorant (Phalacrocorax carbo) sampled at Lake Trasimeno, Italy, by morphological and molecular analysis.

Updates on the distribution of Eustrongylides excisus Jägerskiöld, 1909 (Nematoda: Dioctophymatoidea) in lake fish from northern Italy [PDF]

open access: yes, 2021
INTRODUCTION. Eustrongylides spp. are parasitic nematodes of piscivorous birds and freshwater fish, which act as their definitive and intermediate/paratenic hosts respectively, and are as well recognized as potentially zoonotic parasites. To date, Eustrongylides has been reported from fish and birds from different areas of central Italy (Dezfuli et al.,

Influence of Treated Sewage on Infections of Eustrongylides ignotus (Nematoda: Dioctophymatoidea) in Eastern Mosquitofish (Gambusia holbrooki) in an Urban Watershed

Comparative Parasitology, 2003
The prevalence of eastern mosquitofish (Gambusia holbrooki) infected with larvae of Eustrongylides ignotus declined during an 8-yr period from 54% in 1990 to 0% during the last year at a site near a sewage inflow into a watershed in north-central Florida, U.S.A.

The Development of Eustrongylides tubifex (Nematoda: Dioctophymatoidea) in Oligochaetes

Journal of Parasitology, 1988
Egg development of Eustrongylides tubifex (Nitzsch in Rudolphi, 1819) Jägerskiöld, 1909, was studied at 5, 10, 15, 20, 25, and 30 C. Eggs developed at 20, 25, and 30 C. Development ceased at 0, 5, 10, and 15 C but resumed when temperatures were raised. Eggs contained first-stage larvae in 23-26 days at 25 C.

Trichinelloidea And Dioctophymatoidea

1999
Abstract The order Enoplida, comprising aphasmid nematodes (see the introduction to Part 11), has two superfamilies, Trichinelloidea and Dioctophymatoidea. In addition to the characteristics of the order, outlined in the introduction to Part II, the females of this group have a single genital organ: one ovary, continuing with the ...
