ABSTRACT: Abandonment, irresponsible care, and overpopulation are the main causes of the large number of dogs roaming free in urban areas or living in shelters. 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.

ABSTRACT: The relatively recent surge in Aspidodera species descriptions suggests that several species are yet to be documented and properly described. 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.
摘要:近年来对蛛形纲物种描述的激增表明，有一些物种尚未被记录和适当描述。我们描述了来自巴西塞拉多生物群落(热带草原)的巨型食蚁兽Myrmecophaga tridactyla的serrata Aspidodera n. sp。新种在属中是独特的，因为头侧的条纹，孔状乳头的位置和身体角质层增厚的属性。由于没有从宿主身上找到雄性标本，因此在鉴定过程中，两性相同且属特有的形态特征是基本的。我们强调帽状特征和扫描电子显微镜对基础描述的相关性。我们为该属提供了一个新的关键，以协助识别存在于多种感染中的物种。这是首例在同一个体宿主中与3个同系物合并感染的报道，涉及蛛形线虫。我们敦促研究人员保存和记录易受伤害的四足动物物种的后生动物寄生虫，因为它们可以成为寄生虫在野外分布的宝贵信息来源。

ABSTRACT: Fecal samples collected in April 2019 from 10 half-lidded ovals, Patera binneyana (Pilsbry, 1899) (Gastropoda), in McCurtain County, Oklahoma, U.S.A., were examined for coccidial parasites. Seven (70%) contained oocysts of Pfeifferinella gugleri Wacha, 1980. Ovoidal octozoic oocysts without sporocysts measured (average L × W) 22.2 × 14.1 µm with an L:W ratio of 1.5. Oocysts possessed a subspheroidal to spheroidal oocyst residuum as well as a micropyle. This snail represents the fourth host to harbor this coccidian. We document a new host and geographic distribution record for P. gugleri.

ABSTRACT: During August 2019, 2 stump-tailed geckos, Gehyra mutilata were collected by hand from 2 sites within Peninsular Malaysia and examined for coccidia. 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. Here, we provide additional morphological information on the coccidian, as well as the first photomicrographs of the sporulated oocysts of the species.

ABSTRACT: Five Cape fur seals, Arctocephalus pusillus pusillus, 1 dusky kob, Argyrosomus coronus, and 55 silver kob, A. inodorus, collected from Cape Cross, Henties Bay, and Skeleton Coast Park, Namibia, were examined for acanthocephalans. Adults of Bolbosoma vasculosum and Corynosoma australe were recovered from 5 Cape fur seals, and cystacanths of C. australe from the single dusky kob and 3 of the silver kobs that were examined. This is the first record of B. vasculosum and the second of C. australe from the Namibian coast. Scanning electron microscopy of specimens of C. australe revealed features such as bursal papillae and micropores both on the proboscis hook surfaces and across the epidermal surface of the trunk. X-ray analyses of gallium cut hook, egg, and spines of C. australe are presented with analyses of spines of Corynosoma strumosum for comparison.

Abstract: A new nematode, Cosmocercoides minshan n. sp. (Cosmocercidae) is described from Bufo minshanicus in the Zoige grassland in southwestern China. 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.

abstract: We report zoonotic Spirometra erinaceieuropaei (Rudolphi, 1819) Faust, Campbell and Kellogg, 1929 (Diphyllobothriidae), from its natural ecosystem in Europe from Martes martes in Ukraine. Scanning electron microscopy (SEM) images revealed the presence of mineral concretions in the scolex area of S. erinaceieuropaei. The combination of SEM and metal analysis using a dispersive X-ray technique to study the body surface of the plerocercoid and calcareous body–like structures has never been performed before in cestodes. Gallium ion sectioning and metal analysis were performed to study mineral concretions in cestodes for the first time. The results revealed moderate levels of calcium, phosphorus, and magnesium in the scolex and tegument of plerocercoids. Calcareous body–like structures included high levels of calcium and moderate levels of magnesium on their surface.

abstract: This is the first report of nasopharyngeal myiasis by the larvae of Cephenemyia jellisoni infecting white-tailed deer (Odocoileus virginianus) from tropical dry forests in central Mexico. This study was conducted on hunted male deer within 2 wildlife management units located in the states of Puebla and Oaxaca. Bot fly larvae prevalence in both populations was 50% (95% CI: 21–78%, n = 12) with a median intensity of 4 (95% CI: 3–7). We recommend the implementation of a surveillance program at management units and the monitoring of female deer to determine differential gender effects.

We recommend the implementation of a surveillance program at management units and the monitoring of female deer to determine differential gender effects.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"87 1","pages":"106 - 108"},"PeriodicalIF":0.5,"publicationDate":"2020-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46623195","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}

abstract: Kissing bugs (Hemiptera: Reduviidae) are blood-feeding ectoparasites found primarily in the tropics and subtropics of the Americas. These bugs are vectors of Trypanosomatidae to their mammalian hosts, including humans. The distribution of Triatoma spp. in the Nearctic region is still not fully known, and their relevance as possible vectors of Trypanosoma cruzi to humans and animals is of growing concern. We report the first record of Triatoma sanguisuga from Wyoming, the northern-most reported collection in the western United States, and include collection records for Triatoma protracta in Colorado that were previously unclear.
