Trematoda: Microphallidae)

Bell (with three tables and four text-figures) BELL, P. J" t9g8 (31:x): A study of the life history of Microphallus paragrapsi Smith 1983 (Trematoda : Microphallidae), Pap, Proc. R. Soc. Tasm. 122(2): 119,·125, ISSN 0080-4703. 43 Waterloo Crescem, Battery Point, Tasmania, Australia 7000; formerly Department of Zoology, University of Tasmania. Metacercariae of the micropha\lid trematode Microphallus paragrapsi Smith 1983 were found in r.he nervous system of the smooth pebble crab Philyra laevis (Bell 1855). Sporocysts of M. paragrapsi were found in the hepatopancreas of the intertidal gastropod Assiminea brazieri (Tenison Woods 1876). Under laboratory conditions, cercariae were found to emerge from the snail host and invade the intertidal crab P, iaevis, where they subsequently encysted within the nerves innervating the legs and claws. Adults of M. para/irapsi were found in the gut of the Pacific gull Lams pacificus (Latham 18(1). The life history of M. paragrapsi is very similar to the life history of the related species Microphallus pachygrapsi Deblock & Prevo! 1969. Key Words: Microphallus paragrapsi, life-history, microphaIHd, crab, Tasmania. INTRODUCTION 200 crabs examined throughout the study period, none were infected by M. paragrapsi and only one In 1982, during a study of parasites of the crab was found to be infected with a single cyst of smooth pebble crab Philyra laevis (Bell 1855), the trematode Maritrema eroliae Yamaguti 1939. metacercariae were found in the nervous system of Metacercarial cysts were dissected free of crabs from a number of localities in Tasmania. -

Digenea, Microphallidae) and Relative Merits of Two-Host Microphallid Life Cycles
Parasitology Research (2018) 117:1051–1068 https://doi.org/10.1007/s00436-018-5782-1 ORIGINAL PAPER Microphallus ochotensis sp. nov. (Digenea, Microphallidae) and relative merits of two-host microphallid life cycles Kirill V. Galaktionov1,2 & Isabel Blasco-Costa3 Received: 21 July 2017 /Accepted: 23 January 2018 /Published online: 3 February 2018 # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract A new digenean species, Microphallus ochotensis sp. nov., was described from the intestine of Pacific eiders (Somateria mollissima v-nigrum) from the north of the Sea of Okhotsk. It differs from other microphallids in the structure of the metraterm, which consists of two distinct parts: a sac with spicule-like structures and a short muscular duct opening into the genital atrium. Mi. ochotensis forms a monophyletic clade together with other congeneric species in phylograms derived from the 28S and ITS2 rRNA gene. Its dixenous life cycle was elucidated with the use of the same molecular markers. Encysted metacercariae infective for birds develop inside sporocysts in the first intermediate host, an intertidal mollusc Falsicingula kurilensis. The morphology of metacercariae and adults was described with an emphasis on the structure of terminal genitalia. Considering that Falsicingula occurs at the Pacific coast of North America and that the Pacific eider is capable of trans-continental flights, the distribution of Mi. ochotensis might span the Pacific coast of Alaska and Canada. The range of its final hosts may presumably include other benthos- feeding marine ducks as well as shorebirds. We suggest that a broad occurrence of two-host life cycles in microphallids is associated with parasitism in birds migrating along sea coasts. -
And Interspecific Competition Among Helminth
Available online at www.sciencedirect.com International Journal for Parasitology 38 (2008) 1435–1444 www.elsevier.com/locate/ijpara Intra- and interspecific competition among helminth parasites: Effects on Coitocaecum parvum life history strategy, size and fecundity Cle´ment Lagrue *, Robert Poulin Department of Zoology, University of Otago, 340 Great King Street, P.O. Box 56, Dunedin 9054, New Zealand Received 5 February 2008; received in revised form 4 April 2008; accepted 7 April 2008 Abstract Larval helminths often share intermediate hosts with other individuals of the same or different species. Competition for resources and/ or conflicts over transmission routes are likely to influence both the association patterns between species and the life history strategies of each individual. Parasites sharing common intermediate hosts may have evolved ways to avoid or associate with other species depending on their definitive host. If not, individual parasites could develop alternative life history strategies in response to association with particular species. Three sympatric species of helminths exploit the amphipod Paracalliope fluviatilis as an intermediate host in New Zea- land: the acanthocephalan Acanthocephalus galaxii, the trematode Microphallus sp. and the progenetic trematode Coitocaecum parvum. Adult A. galaxii and C. parvum are both fish parasites whereas Microphallus sp. infects birds. We found no association, either positive or negative, among the three parasite species. The effects of intra- and interspecific interactions were also measured in the trematode C. parvum. Both intra- and interspecific competition seemed to affect both the life history strategy and the size and fecundity of C. parvum. Firstly, the proportion of progenesis was higher in metacercariae sharing their host with Microphallus sp., the bird parasite, than in any other situation. -

Cercariae were tested for photokinetic and geotactic responses, and a behavioral etho- gram was established for cercariae in control and grass shrimp-conditioned brackish water.

FA is predicted to increase in response to environmental stress, 17 including parasite infection. In addition, theory predicts higher FA in sexually selected traits, due to their 18 greater sensitivity to stress.

Behavioral analysis of a digenetic trematode cercaria ( Microphallus turgidus ) in relation to the microhabitat of grass shrimp ( Palaemonetes spp.) by Patricia O’Leary (Under the Direction of Oscar J. Pung) Abstract The hydrobiid snail and grass shrimp hosts of the microphallid trematode Microphallus turgidus are found in specific microhabitats. The primary second intermediate host of this parasite is the grass shrimp Palaemonetes pugio. The behavior of trematode cercaria often reflects the habitat and behavior of the host species. The objective of my study was to examine the behavior of M. turgidus in relation to the microhabitat selection of the second intermediate host. To do so, I established a behavioral ethogram for the cercariae of M. turgidus and compared the behavior of these parasites to the known host behavior. -

Two helminth parasites com- monly use this crustacean species as second intermediate host. One of them, Coitocaecum parvum,isa progenetic trematode with an egg-producing metacercaria occasionally reaching 2.0 mm in length, i.e. more than 50% the typical length of its amphipod host. The amphipod was shown to exhibit the common reproductive features of most precopula pair-forming crustaceans, i.e. larger males and females among pairs than among singles, more fecund females in pairs, and a trend for size-assortative pairing. -
