A Merganser Die-Off Associated with Larval Eustrongylides
Avian Diseases, 1964Although several species of Eustrongylides have been reported from mergansers, there is only one report in the North American literature of merganser losses due to nematodes of this genus. Giltner (4) included a report by J. E. Shillinger, U.S. Bureau of Biological Survey, which mentioned losses due to Eustrongylides mergorum among these fish-eating ...

The Development of Eustrongylides tubifex (Nematoda: Dioctophymatoidea) in Oligochaetes
The Journal of Parasitology, 1988Egg 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.

Morbidity and Mortality of Great Blue Herons in Indiana Caused by Eustrongylides ignotus
Avian Diseases, 1977The cause of the frequent high losses and morbidity in young herons, especially under a year old, has been generally obscure (7). Bowdish (1) and Locke (5) indicated, however, that the nematode Eustrongylides ignotus was the cause of fatalities in herons and egrets on the East Coast of the United States.

Journal of Parasitology, 2003
Under laboratory conditions, 2 modes of transmission of Eustrongylides ignotus (Nematoda: Dioctophymatoidea) to fish were identified. Eastern mosquitofish (Gambusia holbrooki) became infected after ingestion of either eggs of E. ignotus containing first-stage larvae or aquatic oligochaetes (Limnodrilus hoffmeisteri) containing third-stage larvae of E ...

The Larvae of Eustrongylides ignotus in Fundulus heteroclitus
The Journal of Parasitology, 1945Eustrongylides larvae occur in Fundulus diaphanus (Chapin, 1926; Mueller, 1934), in Fundulus heteroclitus (von Brand, 1938), as well as in a variety of other fish (Hunter, 1937, 1942; von Brand, 1944). It is not possible to decide at the present time whether they all belong to one species, since the larvae of the various species are extremely similar ...

Avian Diseases, 1978
The occurrence of Eustrongylides sp. is reported for five species of fish-eating birds collected in the western-basin region of Lake Erie. Mature specimens of E. tubifex were recovered from 5 of 74 laboratory-reared Mallards (Anas platyrhynchos) infected experimentally with larval worms taken from Yellow perch, Perca flavescens.

Eustrongylides sp. Epizootic in Young Common Egrets (Casmerodius albus)
Avian Diseases, 1988In May 1985, epizootic mortality was reported in common egrets (Casmerodius albus) on Avery Island, Louisiana. Subsequent investigation revealed that more than 400 birds died. Severe peritoneal nematodiasis (Eustrongylides sp.) was found on postmortem examination. A nearby breeding rookery on the same island was apparently unaffected.

Russian Journal of Biological Invasions, 2019
The data on the finding of Eustrongylides excisus in the Rybinsk Reservoir (Yaroslavl oblast, Russia) are presented. Larvae-IV were recorded in 2015 in ruff. The appearance of this nematode in the reservoir is associated with the expansion of the range of cormorant, its main definitive host. E.

Eustrongylides (Nematoda) Infection in Mummichogs and Other Fishes of the Chesapeake Bay Region
Transactions of the American Fisheries Society, 1986Abstract A survey of mummichogs Fundulus heteroclitus for Eustrongylides sp. (Nematoda) infection was conducted at 20 Chesapeake Bay tributary stations in 1983. Factors that might influence the prevalence of infection, including both station characteristics (salinity of the water and density of oligochaete intermediate hosts) and mummichog ...

We examined mosquitofish (Gambusia holbrooki) caught between January 1990 and December 1991 from 24 sites in northern Florida (USA), and preserved specimens collected from 32 sites throughout Florida between 1930 and 1978, for presence of the larval nematode Eustrongylides ignotus.
