AbstractThe helminths of two sympatric species of rodents, the striped field mouse Apodemus agrarius and the yellow-necked mouse, Apodemus flavicollis from Slovakia were studied to determine whether there are similarities in the composition of the helminth fauna of two closely related host species living in the same area. A total of twelve species of helminths were identified in these rodent populations, including Brachylaima sp. (Trematoda); Hymenolepis diminuta (Rudolphi, 1819), Mesocestoides sp. larvae, Rodentolepis fraterna (Stiles, 1906), Rodentolepis straminea (Goeze, 1782), Skrjabinotaenia lobata (Baer, 1925), Taenia taeniaeformis larvae (Batsch, 1786) (Cestoda); Aonchotheca annulosa (Dujardin, 1845), Heligmosomoides polygyrus (Dujardin, 1845), Heterakis spumosa Schneider, 1866, Mastophorus muris (Gmelin, 1790) and Syphacia stroma (Linstow, 1884) (Nematoda). In A. agrarius, H. polygyrus was the most prevalent, as well as the most abundant helminth, but R. fraterna was the species with the highest mean intensity. In contrast, S. stroma dominated the A. flavicollis helminth fauna with the highest prevalence, mean abundance and mean intensity. Both rodent populations harboured nine helminth species, although the mean individual species richness was significantly higher in A. agrarius than in A. flavicollis. The analysis of helminth diversity at both component and infracommunity levels revealed differences between the two rodent populations, which are most likely attributable to the specific host ecology.

Based on published records and unpublished information retrieved from the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC), a checklist of the helminth parasites of cetaceans from Brazil was generated. A total of 215 records of 18 species of helminths were associated with 22 species of cetaceans in Brazil. Six species determined only to genus were also included. The majority of these helminth species are nematodes (33.3%) and trematodes (33.3%), which total 66.6% of the helminth fauna of cetaceans from Brazil. The Acanthocephala represents 22.2% of species, and the Cestoda 11.1%.

ABSTRACTFive cestode, one monogenean, and two nematode species comprised the “normal” intestinal helminth fauna of Raja naevus in British waters. An additional two nematodes, a digenean, an acanthocephalan and a crustacean recorded are considered to be accidental infections. Geographical differences in the species composition and level of infection are noted and discussed. Short descriptions of the tetraphyllidean cestode Echeneibothrium sp. and the nematode Capillaria sp. are given, but the species, although probably both new, are left unnamed. The intensity of cestode infections show two patterns associated with host length and these are discussed in relation to variations in host diet. Speculations are made on the cestode life cycles. Only Echeneibothrium sp. numbers showed any significant variation associated with host sex.

AbstractThe helminth fauna of weatherfish (Misgurnus fossilis) in natural range is reviewed. Several helminth species reported in weatherfish are discussed with reference to host specificity and their geographical distribution. The current list of helminth parasites of the weatherfish includes 37 species. Most (15) are digenean trematodes, half of them being larval stages. Only one species of trematode — Allocreadium transversale is more specific parasite of weatherfish. Second largest group are Monogenea, with 10 species. Two of them (Gyrodactylus strelkovi and G. misgurni) are found only in the genus Misgurnus. Tapeworms (6 species) and Nematodes (6 species) are less numerous. No Acanthocephala, however, were ever found.

In order to contribute to the knowledge on helminth parasites of freshwater fishes in Mexico, the helminth fauna of the cyprinid fish Notropis moralesi was studied. The helminth species Bothriocephalus acheilognathi and Rhabdochona canadensis were recovered from 20 examined hosts. Values of prevalence, abundance and mean intensity of each infection are provided. Present work represents the first helminthological study for N. moralesi. Therefore, both helminth species recorded are new host records. This is the second report of B. acheilognathi and the first of R. canadensis for the state of Puebla.

Twenty specimens of Petrogale persephone were examined for parasites. Nineteen species of helminths, one species of tick, one louse, one mite and two species of intestinal protozoans were recovered. The assemblage of helminth parasites encountered more closely resembled those found in Thylogale species than other species of rock-wallaby. The possible origins of the helminth fauna of P. persephone are discussed. The single species of tick, Haemaphysalis petrogalis, and the louse, Heterodoxus sp. 14, are specific to rock-wallabies, while the mite, Thaddeua serrata has a broader host range. Parasites causing significant lesions in P. persephone were the metacestode of Echinococcus granulosus and the mite T. serrata. Parasites found in small numbers but considered potential disease agents in this host were Globocephaloides macropodis, Hypodontus macropi, Eimeria petrogale and E. sharmani.

1. Ninety-six lesser black-backed gulls, Larus fuscus L., captured at about 6 weeks of age, were kept in captivity for up to 2⅛ years. At intervals some gulls were killed and examined for helminth parasites, of which 14 species were found comprising 4 species of Trematoda, 5 species of Cestoda and 5 species of Nematoda.2. Nine of the 14 species are commonly found in Holarctic gulls and may be regarded as characteristic members of the helminth fauna of these birds. Six species are recorded from L. fuscus for the first time.3. The life span of different species of helminth parasites in L. fuscus varied from 2 months to 2⅛ years; few specimens lived in their host for more than one year. During captivity there was a marked decline in the variety of the helminth fauna of individual gulls, as well as a general decline in the incidence and intensity of infection with individual species of parasites. There was one exception, the tape-worm Tetrabothrius cylindraceus, which increased in incidence and maintained a fairly even intensity of infection in L. fuscus over 21 months. The results are discussed in relation to the ecology of the parasite and the host.

Using published records and original data derived from my research, a checklist was generated of the helminth parasite fauna in 194 native and 18 introduced freshwater fish species from 30 families from Mexico. The checklist contains 262 nominal species, from 152 genera and 59 families of helminth parasites. It includes 37 species of adult trematodes, 52 metacercariae, 49 monogeneans, 15 adult cestodes, 22 metacestodes, 7 adult acanthocephalans, 5 cystacanths, 56 adult nematodes and 19 larval nematodes. Most of these species (150, 57%) are Neotropical, 35 (13%) are Nearctic, and 28 (11%) are either anthropogenically introduced into Mexico (21 of them), or are world-wide in their distribution (7 species). Insufficient data preclude the determination of the status of the rest of the species. Only 18 of these species are tentativelly pointed out as endemic to Mexico, although 55 species are recognized as being endemic to Mesoamerica. The data demonstrate that the helminth fauna of freshwater fish in Mexico is divided into Neotropical and Nearctic components with no apparent transition zone between them. The Nearctic fauna mainly consists of allogenic generalist species capable of invading Neotropical hosts and environments, but the Neotropical fauna, mostly autogenic and consisting of specialists to certain host families, is limited to Neotropical environments and hosts. This Neotropical fauna forms part of a Mesoamerican zone that extends from southeast Mexico along the Gulf of Mexico slope and into Central America. Fish families have typical groups of helminth species which allows the spatial distribution of helminths to follow that of their hosts. Together with their allogenic generalist characteristics, this gives this helminth fauna a broad distribution that covers Mexico’s Neotropical and Nearctic basins.
