First Time

The family Planorbidae comprises freshwater gastropods with planispiral, spiral and limpet-shaped shells. Subfamily Planorbinae sensu stricto, has a richness of almost 300 species, with some of the main genera being Biomphalaria Preston, 1910 and Drepanotrema Fischer & Crosse, 1880. Some Biomphalaria species are of concern to human health as they are intermediate hosts of blood flukes in Latin America. In Argentina, the family Planorbidae is represented by 15 species in four genera. In Northern Argentina (NOA region), records of the family are scarce, and most of them are a result of occasional collecting. We provide an updated checklist of Planorbinae in NOA resulting from fieldwork, material in malacological collections, and data in the literature. Nine species occur in the area: four species of Biomphalaria and five of Drepanotrema. Among Biomphalaria species, we recorded Biomphalaria straminea (Dunker, 1848), which is considered a natural host of the blood fluke Schistostoma mansoni Sambon, 1907, for first time in Salta province; the known geographic distribution of B. straminea is extended in the country.

Molluscan Fauna

During a part of the years 1937 and 1938 a biological study of the fresh-water mollusca of the Tanganyika Territory and Zanzibar Protectorate was carried out with the aid of the grant of the Wandsworth Scholarship of the London School of Hygiene and Tropical Medicine. Up to the present little has been known about the molluscs of this part of Africa, although the importance of certain members of this group as the intermediate hosts of human blood flukes (Schistosoma spp.) has been widely recognized. The following account of the constitution and distribution of the molluscan fauna of this region may therefore be of interest and value.

Bird schistosomes are commonly established as the causative agent of swimmer's itch − a hyper-sensitive skin reaction to the penetration of their infective larvae. The aim of the present study was to investigate the prevalence of the genus Bilharziella in comparison to other bird schistosome species from Lake Drawsko − one of the largest recreational lakes in Poland, struggling with the huge problem of swimmer's itch. In total, 317 specimens of pulmonate snails were collected and examined. The overall digenean infection was 35.33%. The highest bird schistosome prevalence was observed for Bilharziella sp. (4.63%) in Planorbarius corneus, followed by Trichobilharzia szidati (3.23%) in Lymnaea stagnalis and Trichobilharzia sp. (1.3%) in Stagnicola palustris. The location of Bilharziella sp. on the presented phylogeny showed that it is with high probability a different species than known so far B. polonica. Our finding complements the confirmed occurrence of bird schistosomes in European water bodies. Overall, presented research reveals the special importance of P. corneus as a source of the bird schistosome cercariae. This study suggests that the health threat connected with the blood flukes need to be further investigated by constant monitoring of their occurrence in intermediate hosts.

Cercarial dermatitis is a neglected zoonotic disease with distribution all over the world’s temperate zones. It is caused by cercariae, a larval stage of parasitic blood flukes of the genus Trichobilharzia that is a parasite of waterfowl. When cercariae burry into human skin, they trigger an allergic reaction that leads to severely itching papules. Goal of this research was to get an overview over the distribution of cercariae in the bathing places of Schleswig-Holstein, the most northern state of Germany. Therefore, all public bathing places were visited and searched for fresh water snails that are the potential intermediate hosts of cercariae. Water snails of different families and genera were collected and examined for the presence of cercariae. Water samples were taken and examined for cercariae via a microscope. Additionally slime samples of the water snails were taken to test a new, time saving method of detection. In total 8 different kinds of water snails were collected and examined, of which the families of Lymnaeidae and Planorbidae proved to be the most common hosts of cercariae. In total, the results indicate a spatial distribution of cercariae shedding snails all over Schleswig-Holstein.
