The helminths are generalist and have indirect life cycles with the exception of S. garciaprietoi. We provided new host and distribution records for the 3 helminth species (Mesocestoides sp., P. retusa, and S. garciaprietoi) and present the first helminth reports for S. horridus, S. ochoterenae, and U. bicarinatus.

These shelters provide temporary homes for dogs that have been lost, abused, or reported for biting, but also provide an environment that could enable the spread of gastrointestinal parasites. City municipal shelters receive dogs throughout the year, feed them, and provide veterinary care before offering them for adoption. This article reports on the intestinal parasite infections of municipal shelter dogs from San Carlos de Bariloche, Río Negro, Argentina, over 3 consecutive years. Fecal samples were collected from all shelter dogs during the winters of 2017, 2018, and 2019. The samples were examined using Sheather's flotation and Ziehl Neelsen stain techniques to detect parasite eggs and coccidia, respectively. Total prevalence values ranged from 32 to 45%, with a total of 6 parasite taxa found, including coinfections, with a maximum of 2 species. Some dogs seemed to become infected during their stay in the shelter, and despite periodic deworming, some dogs were still parasitized. Zoonotic parasites like Toxocara canis, Toxascaris leonina, and Dibothriocephalus latus were identified in this study. Thus, such shelter dogs may act as disseminators of transmission stages of zoonotic parasites. This work emphasizes the importance of raising awareness about the responsible care of companion animals to prevent the need for shelter care.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"88 1","pages":"15 - 18"},"PeriodicalIF":0.5,"publicationDate":"2021-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44208633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe Aspidodera serrata n. sp. from the giant anteater Myrmecophaga tridactyla from the Cerrado biome (Savanna), Brazil. The new species is distinctive in the genus because of the attributes of the cephalic cordons, position of pore-like papillae and a thickening of body cuticle. Because no male specimens were recovered from the host, morphological characteristics that are identical in both sexes and specific for the genus were fundamental during the identification. We emphasize the relevance of hood features and scanning electron microscopy to base descriptions in Aspidodera. We provide a new key for the genus to assist in the efforts to identify the species present in multiple infections. This is the first report of a coinfection with 3 congeners in the same individual host involving Aspidodera. We urge researchers to preserve and document the metazoan parasites from tetrapod species considered vulnerable, because they can be valuable sources of information on the distribution of parasites in the wild.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"88 1","pages":"7 - 14"},"PeriodicalIF":0.5,"publicationDate":"2021-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43688472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both were found to be passing oocysts of Eimeria cf. cicaki Else and Colley, 1975. Oocysts are subspheroidal to ellipsoidal, with a smooth bilayered wall, measure 19.4 ×16.1 µm, and have a length/width (L/W) ratio of 1.2; a micropyle and oocyst residuum are absent, but a single polar granule is present. Sporocysts are ellipsoidal and measure 7.3 × 6.7 µm, L/W 1.1; Stieda, sub-Stieda, and para-Stieda bodies are absent. The sporocyst residuum is composed of large dispersed granules lying between the sporozoites. The current isolate appears to be morphologically divergent from the specimens as originally described. Previously reported endogenous development shows this coccidian should be transferred to the genus Acroeimeria Paperna and Landsberg, 1989.

The new species is characterized as a medium-sized worm (4.93–7.97 mm in length and 0.24–0.47 mm in width), but with a shorter spicule length (0.08–0.21 mm) than other Cosmocercoides, with lateral alae and 9 pairs of caudal papillae. Among the 21 recorded species in this genus, the morphology of the new species is different from all the other species previously reported. DNA sequences of C. minshan sp. showed that the species is almost identical to Cosmocercoides pulcher (99%), and Cosmocercoides tonkinensis (99%). However, there are differences in the morphology and structure of the rosetted papillae among these 3 species, as well as 4 nucleotide differences in the 18S–28S rDNA including the internal transcribed spacer region. In a neighbor-joining phylogenetic tree, C. tonkinensis, C. pulcher, and C. minshan formed a robust clade. Generally, the species is distinguished molecularly and morphologically; thus C. minshan is herein described as a new nematode species of Cosmocercoides.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"87 1","pages":"121 - 126"},"PeriodicalIF":0.5,"publicationDate":"2020-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46697121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
