Euhaplorchis californiensis is a trophically transmitted parasite (TTP) that lives in the salt-water marshes of Southern California, United States. It lives in three hosts: shorebirds, horn snails, and killifish. As with many TTPs, E. californiensis modifies the behavior of the host to increase the likelihood of transmission to its next host.

As a heavily r-selected species, Euhaplorchis californiensis experiences extremely high mortality rates in many of its life stages. Like most trematodes, adult E. californiensis worms are capable of producing hundreds to thousands of eggs in a single day.

Working with others to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people.

2020年2月25日 · This is the case for Euhaplorchis californiensis, a brain-encysting trematode parasite that causes behavioral changes in the California killifish (Fundulus parvipinnis). These manipulations increase predation by the parasite's final host, piscivorous marsh birds.

2009年3月3日 · California killifish (Fundulus parvipinnis) infected with the brain-encysting trematode Euhaplorchis californiensis display conspicuous swimming behaviours rendering them more susceptible to predation by avian final hosts. Heavily infected killifish grow and reproduce normally, despite having thousands of cysts inside their braincases.

2012年2月7日 · Euhaplorchis californiensis is a common common trematode in southern California and Baja California estuaries that spends most part of its life parasitizing in the brain of the Pacific killifish (Fundulus parvipinnis), one of the most common fishes in these estuaries and second intermediate host.

Euhaplorchis californiensis is a trophically transmitted parasite (TTP) that lives in the salt-water marshes of Southern California. It lives in three hosts: shorebirds, horn snails, and killifish. As with many TTPs, E. californiensis modifies the behavior of the host to increase the likelihood of transmission to its next host.

2023年7月1日 · Euhaplorchis californiensis and SMCY infection caused 1.8- and 2.5-fold overall increases in conspicuous behaviors, respectively. Each parasite was also associated with increases in specific conspicuous behaviors, particularly 1.9- and 1.4-fold more darting.

The trematode parasite Euhaplorchis californiensis produces cercariae that emerge from California horn snails ( Cerithideopsis californica [= Cerithidea californica]) to infect California killifish ( Fundulus parvipinnis) as second intermediate hosts.

An example of a parasite with a complex life cycle is the trematode, Euhaplorchis californiensis (Figure 4) 1996). These behaviors cause an infected killifish to be 10-30 times more likely to...
