Amphibians and larvae of aquatic insects as new paratenic hosts of Anguillicola crassus (Nematoda: Dracunculoidea), a swimbladder parasite of eels.
Amphibians (tadpoles of the frog Bombina bombina [L.] and the newt Triturus vulgaris [L.]) and aquatic insects (larvae of the alderfly Sialis lutaria [L.] [Megaloptera], dragonflies Sympetrum sanguineum [Miller] and Coenagrion puella [L.] [Odonata], and the caddisfly Oligotrichia striati [L.] [Trichoptera]) were found to serve as paratenic hosts for the third-stage larvae (L3) of the nematode A...
متن کاملRadiodiagnostic method for studying swimbladder inflammation caused by Anguillicola crassus (Nematoda: Dracunculoidea).
The nematode Anguillicola crassus appeared in Europe about 15 yr ago, and has subsequently become recognised as a cause of major pathological lesions in the swimbladder of the European eel Anguilla anguilla. The radiographic method reported in this paper showed be a useful complement to diagnostic methods that have so far been based exclusively on fish dissection. Using this method, the infecti...
متن کاملEffect of salinity on hatching, survival and infectivity of Anguillicola crassus (Nematoda: Dracunculoidea) larvae.
The effect of salinity on hatching, larval survival and infectivity of Anguillicola crassus was studied under experimental conditions using eggs obtained from naturally infected eels. Egg hatching rate, second-stage larval survival and larval infectivity were maximal in fresh water and declined with increase in salinity. Larvae survived up to 100 d in fresh water, 70 d in 50 % sea water and 40 ...
متن کاملThe first record of amphibians as paratenic hosts of Serpinema larvae (Nematoda; Camallanidae).
Until now the third-stage larvae of Serpinema trispinosum (Leidy, 1852) was only found infecting aquatic snail and planktonophagous fish as paratenic hosts (Bartlett and Anderson, 1985; Moravec et al., 1998). The life cycle of this nematode is unknown. Apparently, the freshwater turtles may become infected by ingestion of zooplankton intermediate hosts (e.g., copepods) or by feeding on parateni...
متن کاملRadiodiagnostic method for studying the dynamics of Anguillicola crassus (Nematoda: Dracunculoidea) infection and pathological status of the swimbladder in Lake Balaton eels.
Swimbladder changes resulting from Anguillicola crassus infection of the European eel Anguilla anguilla have been the subject of several studies reported in the literature. These investigations, however, studied exclusively the status of infection at a given point in time and did not deal with changes in swimbladder infection in eels suffering from anguillicolosis over a period of time. In this...
