Contribution to the histology of Biomphalaria glabrata [PDF]

open access: yesRevista 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,

Mapping molluscan endocrinology: a systematic and critical appraisal

open access: yesBiological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Breeding of Biomphalaria tenagophila in mass scale [PDF]

open access: yesRevista 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.
