abstract: Humans can become infected by Toxoplasma gondii oocysts released in the environment along with felid feces through the accidental ingestion of contaminated raw meat, water, fruits and vegetables, or through direct contact with contaminated soil. Documenting the extent of soil contamination by T. gondii oocysts is necessary to prevent infection caused by this protozoan. The aim of our study is to determine the occurrence of T. gondii oocysts in urban soil in Marrakesh, Morocco. A total of 42 soil samples were collected from 9 sites in the urban area of Marrakesh. Oocysts were extracted by the flotation method, and detected by microscopy using both bright-field and UV. The frequency and spatial distribution of T. gondii in soil were analyzed considering the factors that could affect the mode of contamination, such as the presence of cats and the survival conditions of oocysts. All analyzed soil samples from Marrakesh were negative. The results of the present study are correlated to the sensitivity of our detection method as well as the presence of cats, the main reservoir of this parasite. In addition, temperature, moisture, and soil composition can significantly influence oocysts survival, and consequently affect the probability of human contamination through food.

abstract: Natural infections of Paulisentis missouriensis (Acanthocephala), Rhabdochona canadensis (Nematoda), and Allocreadium lobatum (Trematoda) in the intestine of creek chub (Semotilus atromaculatus) were studied to determine whether microhabitat use of these helminths was affected by interspecific interactions. Comparison of mean relative positions and intestinal segment use of all 3 helminths revealed no negative interactions among the 3 species. Paulisentis missouriensis appeared entirely unaffected by the presence of either R. canadensis or A. lobatum. Each of the latter 2 species, however, appeared to exhibit some shift toward, rather than away from, the location of P. missouriensis in co-infected hosts. However, the effect size in both cases was small and therefore could be spurious. At higher intensities of co-infecting P. missouriensis, worms of A. lobatum were either distributed far to the anterior or far to the posterior of the intestinal locations occupied by P. missouriensis. This constituted the only evidence in the present investigation for negative interspecific interactions among these 3 frequently co-occurring helminths in this system.

abstract: Herein, we present the first Mexican record of Morelet's crocodile, Crocodylus moreletii, as a host for the proboscis-bearing leech, Haementeria acuecueyetzin. From November 2004 to October 2017, we captured 111 crocodiles during spotlight surveys in lagoons of the Dziuché ejido, municipality of José María Morelos, Quintana Roo, Mexico. Twenty-one (18.9%) individuals had leeches identified as H. acuecueyetzin. It is the first report of H. acuecueyetzin for the State of Quintana Roo, Mexico, and the northernmost record of the species. This is also the second case of leech parasitism in C. moreletii. Haementeria acuecueyetzin likely parasitize a large array of vertebrates, and its role as a potential vector of blood parasites in C. moreletii requires further investigation.
本文报道了墨西哥首次记录的莫雷特鳄(Crocodylus moreletii)作为长鼻水蛭Haementeria acuecueyetzin的宿主。2004年11月至2017年10月，我们在墨西哥金塔纳罗奥州jos María Morelos市dziuch ejido的聚光灯调查中捕获了111条鳄鱼。21例(18.9%)被鉴定为水蛭。这是墨西哥金塔纳罗奥州首次报道的H. acuecueyetzin，也是该物种最北的记录。这也是第2例水蛭寄生于莫雷雷弧菌。急性Haementeria acuecueyetzin可能寄生于大量脊椎动物，其作为C. moreletii血液寄生虫潜在媒介的作用有待进一步研究。

abstract: Camallanus philippinensis n. sp. (Spirurida; Camallanidae) from the intestines of Occidozyga laevis (Günther, 1858) (Anura; Dicroglossidae) is described and illustrated. Camallanus philippinensis n. sp. represents the 106th species assigned to the genus and the first from Philippine anurans. It is distinguished from other Oriental species by the pattern of caudal papillae (6 precloacal, 4 adcloacal, 8 postcloacal), length of spicule (323–329 µm), and postequatorial vulva. Occidozyga laevis is also found to harbor cyclophyllidean cysticerci. Occidozyga laevis represents a new host record for both of these helminths.

abstract: We describe a monogenean species new to science belonging to Markewitschiana, a genus characterized by the absence of anchors. Markewitschiana agdazensis n. sp. parasitizes the gills of Luciobarbus pallaryi (Cyprinidae) in Morocco. The newly described species is characterized by the presence of 7 pairs of hooks; 1 pair of “ventral structures” resembling vestiges of anchors; bar cruciform-shaped; male copulatory organ a long tube, beginning with a bulb, accessory piece tubular and articulated at the base of the MCO; and sclerotized vagina elongated with enlarged opening. This is the first report of a species of Markewitschiana outside Asia and on the gills of its fish host; individuals of this genus are usually found in the nasal cavities of their hosts.

abstract: Spiny softshell turtles (Apalone spinifera), common snapping turtles (Chelydra serpentina), and red-eared sliders (Trachemys scripta elegans) were surveyed for leeches at 16 sites across Texas, U.S.A., from March to December of 2017. Five species of leeches were found (3 from 15 A. spinifera sampled, 4 from 9 C. serpentina sampled, and 3 from 55 T. scripta elegans), representing 3 new host records and 1 new locality record. Leech abundance was also compared to water parameters (ammonia, carbon dioxide, chloride, dissolved oxygen, hardness, nitrite, nitrate, pH, salinity, temperature, and turbidity) and qualitative environmental variables (vegetation, sediment, latitude, longitude, season, and water body) through principle components analysis, stepwise regression, and model selection. We found significant effects of sediment composition and seasonality on leech abundance. This study adds novel data on leech–host associations, distributions, and diversity in Texas.
摘要:2017年3月至12月，在美国德克萨斯州的16个地点对有刺软壳龟(Apalone spinifera)、普通鳄龟(Chelydra serpentina)和红耳滑龟(Trachemys scripta elegans)进行了水蛭调查。共发现5种水蛭(15种刺麻3种，9种蛇形水蛭4种，55种细纹水蛭3种)，代表3个新的寄主记录和1个新的地方记录。通过主成分分析、逐步回归和模型选择，将水蛭丰度与水体参数(氨、二氧化碳、氯化物、溶解氧、硬度、亚硝酸盐、硝酸盐、pH、盐度、温度和浊度)和定性环境变量(植被、沉积物、纬度、经度、季节和水体)进行比较。我们发现沉积物组成和季节对水蛭丰度有显著影响。这项研究增加了关于德州水蛭寄主关联、分布和多样性的新数据。

abstract: Ten honey badgers (Mellivora capensis wilsoni) and 10 West-Asian blunt-nosed vipers (Macrovipera lebetina obtusa) were collected from the Almadeena district North Basrah governorate, southern Iraq, and examined for helminths. Cystacanths and 2 adult specimens of an acanthocephalan Oligacanthorhynchus sp. were found, and these represent new host records and a new record for Iraq. The specimens could be distinguished from all other species of Oligacanthorhynchus in having a proboscis armature of 36 hooks arranged in 12 rows of 3 hooks without large manubria, the largest hooks (circle 1) up to 120 µ m long. There was, however, insufficient material to adequately describe the putative new species. Honey badgers are opportunistic carnivores that include snakes in their diet, supporting the contention that the vipers are paratenic hosts and honey badgers are the definitive hosts for this oligacanthorhynchid.

Honey badgers are opportunistic carnivores that include snakes in their diet, supporting the contention that the vipers are paratenic hosts and honey badgers are the definitive hosts for this oligacanthorhynchid.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"87 1","pages":"44 - 48"},"PeriodicalIF":0.5,"publicationDate":"2020-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46519067","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}
