Breeding of Biomphalaria tenagophila in mass scale [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2013
An efficient method for breeding Biomphalaria tenagophila (Taim lineage/RS) was developed over a 5-year-period (2005-2010). Special facilities were provided which consisted of four cement tanks (9.4 x 0.6 x 0.22 m), with their bottom covered with a layer of sterilized red earth and calcium carbonate.

Contribution to the histology of Biomphalaria glabrata [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 1999
A combination of histological techniques applied to the study of Biomphalaria glabrata yielded some interesting new data about the histology of this snail, a major intermediate host of Schistosoma mansoni in Brazil. Three kinds of pigments were identified: a dark pigment which bleached following oxidation with potassium permanganate; a lipofuchsin-like,

Biomphalaria glabrata no Estado do Piauí [PDF]

Memórias do Instituto Oswaldo Cruz, 1984
É registrado o primeiro encontro do molusco planorbideo Biomphalaria glabrata, hospedeiro intermediário do Schistosoma mansoni, no Estado do Piauí, coletado em vários criadouros na cidade de Parnaíba. O exame de 694 exemplares revelou a presença de formas evolutivas de algumas espécies de trematodeos, mas não de Schistosomatidea.

Estratégia competitiva entre Biomphalaria glabrata e Biomphalaria tenagophila: estudos de laboratório [PDF]

Memórias do Instituto Oswaldo Cruz, 1989
Observation about conhabitation among B. glabrata and B. tenagophila revealed a greater vulnerability of B. tenagophila population during the process of competition when its density was severaly decreased in 12 trials, moderate in 2 trials. It was higher than B. glabrata in only one trial.

Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

Journal of Fish Biology, EarlyView.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Establishment ofBiomphalaria tenagophilaSnails in Europe

Emerging Infectious Diseases, 2008
To the Editor: Schistosomiasis, known since ancient times, is caused by blood flukes (Trematoda: Schistosomidae). It is a major communicable disease with public health and socioeconomic effects in the developing world (1). Among parasitic diseases, schistosomiasis ranks second only to malaria with regard to the number of persons infected and at risk ...
