An Update in Helminth Fauna and Other Equine Parasites in Cuba

Pesquisa Veterinária Brasileira

ABSTRACT: Horses are highly susceptible to parasitism. Helminth infections cause great harm to the animals and to their breeders. This study aimed at evaluating socioeconomic, cultural and management factors associated with the prevalence of gastrointestinal helminths of horses. A total of 40 farmas the Mangalarga Marchador horse breed were visited in southern Minas Gerais, Brazil, where interviews were conducted. Horse feces were collected on the farms and coproparasitological laboratory tests were conducted to quantify the infection and to identify parasites. Data were tabulated in Epidata and analyzed using the SPSS 20.0 software. A great similarity between breeds was observed, specifically in their profiles, as well as in their animal management techniques and in their parasite control habits. The cyathostome was the most prevalent helminth, followed by Oxyuris and large strongyles. The farms which prioritize only equine production are less likely to have animals with massive he...

A survey was carried out to investigate the presence of cranial helminths in 337 American minks (Mustela vison) from Spain. This information was obtained partly in order to evaluate potential conservation problems and sanitary risks to the congeneric European mink (Mustela lutreola), one of the most endangered carnivores in the world. Skulls and rectal faeces of each specimen were simultaneously analysed. Troglotrema acutum and Skrjabingylus nasicola were found in 5.6% of the M. vison analysed. No cranial lesions were seen in any of the examined skulls. The finding of both helminths in Spanish free-living M. vison specimens enlarges their natural definitive host spectrum in Western Europe. One relatively important focus of T. acutum in M. vison was detected (30.4%) in the Spanish Á lava province while S. nasicola was found to be very infrequent. The suitability of both analytical methods was assessed in order to know to what degree coprological analysis reflects the real prevalence of cranial helminths in this host. It is possible to conclude that coprological analysis can be used instead of necropsies to analyse the possible incidence of pathogenic cranial helminths in mustelids. This aspect is very important and useful when trying to analyse the helminthological status of endangered species such as the native mink (M. lutreola) particularly in areas where both congeneric species are present and strict competition occurs.

We present an updated checklist of helminth species infecting cricetid and heteromyid rodents (Rodentia: Cricetidae and Heteromyidae) distributed in Mexico. For each helminth record, we include information on helminth taxonomy, location within the host, life stage, host associations, collection localities, citation, and museum collections, when available. We recorded more than 73 helminth species from 47 host species distributed across 21 states in Mexico. The present list represents the most up-to-date knowledge of helminth species infecting cricetid and heteromyid rodents in Mexico.

Worm burdens were evaluated and compared in two groups ofthe guinea pig, Cavia poreellus (Linnaeus, 1758): animais of the first group were conventionally maintained in an institutional animal house and those of the second group were openly kept in pet shops in Brazil . Animais from both sources were infected on ly with the nematode Paraspidodera llncinata (Rudolphi, 1819) Travassos, 1914 (10% of prevalence in guinea pigs from the institutional facility and 40% in those animaIs from the pet shop). Other helminth samples recovered from Brazilian guinea pigs during 52 years and that are deposited in the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC) were also analyzed. Paraspidodera llneinala and the cestode Monoecoceslus parcilesliculalus Rêgo, 1960 were identified in these samples. KEY WORDS.

The paper describes the prevalence of helminth species in horses from five localities of Arad County, western Romania: Vinga, Pecica, Arad, Șiria and Lipova. A total of 56 horses (5 foals, 10 yearlings and 41 adults) were sampled in order to establish the parasite spectrum. Faecal samples were processed by McMaster technique. All horses (100%) were parasitized, and five types of helminthes were identified. Digestive strongyles were found in 73.21% of horses, roundworms (Parascaris equorum) in 28.57%, threadworms (Strongyloides westeri) in 8.92%, pinworms (Oxyuris equi) in 12.50%, and tapeworms (Anoplocephala spp.) in 19.64%, respectively. At least two helminth species were found in each individual.

Seventy-six naturally infected bovines, males and females of mixed breed, aged 8 to 12 months-old, were necropsied. The results of necropsy revealed the presence of 9 helminth genera and 16 species, with the following prevalence and mean infection intensity: Haemonchus placei (100.0%; 3895.5); Haemonchus similis (29.0%; 159.6); Cooperia punctata (100.0%; 5595.0); Cooperia spatulata (32.9%; 137.8); Cooperia pectinata (34.2%; 1010.5); Trichostrongylus axei (69.7%; 239.2); Trichostrongylus colubriformis (10.5%; 10.8); Trichostrongylus longyspicularis (2.6%; 0.5); Ostertagia ostertagi (2.6%; 3.1); Ostertagia lyrata (2.6%; 1.5); Ostertagia trifurcata (1.3%; 0.3); Oesophagostomum radiatum (94.7%; 470.9); Trichuris discolor (47.4%; 32.5); Strongyloides papillosus (1.3%; 0.1); Capillaria bovis (9.2%; 1.0) and Bunostomum phlebotomum (2.6%; 0.3). The mean parasitic load was 11,558.5 helminths per bovine. Of the 76 necropsied bovine, 92.1% were infected by 3 to 7 helminth species. Only 7.9% of hosts were parasitized by 8 different helminth species. This study includes the first report of the species Ostertagia lyrata and Ostertagia trifurcata in Minas Gerais state. It should be emphasized that while identifying the helminths collected during necropsy in the present work, observation revealed that an inversion in the mean parasitic intensity is occurring, showing diminishing numbers of Cooperia and an increase in Haemonchus compared to the values reported in the literature.

In order to evaluate the monthly frequency, and the genera of cestode and nematode intestinal populations in stray dogs, post-mortem studies were done at the antirrabies center in the city of the State of Queretaro in Mexico; 201 intestines were obtained from May to September, 2000. Age and sex of each animal were recorded. Results showed a 78.6% frequency of positive dogs, and out of this percentage, 64.6% of the infections were produced by nematodes, and 58.2% by cestodes. 77.4% of the males, and 79.6% of the females were infected. No differences regarding sex or age of the animals (P > 0.05) were detected. The frequency of infected dogs during the months of the trial showed differences (P < 0.05

The house mouse, Mus musculus, has been present in Chile since approximately 1600 AD and it is the most tipically synanthropic rodent in Chile. In order to know its parasites a survey was conducted in three different localities in Santiago. The helminthes community was poor in species and only three nematodes species were found: Syphacia obvelata, Aspiculuris tetraptera and Physaloptera calnuensi. All these species constitutes the first record in Chile. This is also the first record of P. calnuensis in this host. Syphacia obvelata was the most abundant and the most prevalent.
