Factors Affecting Lethality of Bisphenol a on Biomphalaria alexandrina Snails [PDF]
International Journal of Veterinary Science and Research, 2016 The present study was undertaken to investigate the influence of some environmental factors including temperature, water vegetation, bed mud and pH on LC50, LC90 and LT50 of bisphenol A (BPA) on the snail host of Schistosoma mansoni, Biomphalaria alexandrina.

IMMUNE RESPONSE OF STIMULATED BIOMPHALARIA ALEXANDRINA SNAILS WITH SCHISTOSOMA MANSONI INFECTION [PDF]
Journal of the Egyptian Society of Parasitology, 2017 In this study, both digestive and hermaphrodite glands in Biomphalaria alexandrina snails were examined by light microscope (LM) and scanning electron microscopy (SEM) in a trial to clarify its immunological role as defense mechanism against the parasite

Carboxylic acids as biomarkers of Biomphalaria alexandrina snails infected with Schistosoma mansoni. [PDF]
Korean J Parasitol, 2010 Biomphalaria alexandrina snails play an indispensable role in transmission of schistosomiasis. Infection rates in field populations of snails are routinely determined by cercarial shedding neglecting prepatent snail infections, because of lack of a suitable method for diagnosis. The present study aimed at separation and quantification of oxalic, malic,

An immunohistochemical analysis of peptidergic neurons apparently associated with reproduction and growth in Biomphalaria alexandrina. [PDF]
Gen Comp Endocrinol, 2019 Peptide hormones and neurotransmitters involved in reproduction and growth have been studied extensively in certain gastropod molluscs, such as Lymnaea stagnalis and Aplysia californica. The present study employs antisera that have been used to study peptidergic neurons in those species to probe the central nervous system of another gastropod ...

FATTY ACIDS CONTENTS IN BIOMPHALARIA ALEXANDRINA DURING THE COURSE OF INFECTION WITH SCHISTOSOMA MANSONI [PDF]
Journal of the Egyptian Society of Parasitology, 2013 The study examined the effects of larval trematode infection on the neutral lipid and phospholipid content of Biomphalaria alexandrina infected with Schistosoma mansoni. Uninfected snails were used as matched controls.

Identification of a genetic marker associated with the resistance to Schistosoma mansoni infection using random amplified polymorphic DNA analysis [PDF]
Memorias do Instituto Oswaldo Cruz, 2006 In schistosomiasis, the host/parasite interaction remains not completely understood. Many questions related to the susceptibility of snails to infection by respective trematode still remain unanswered.

Myco-Synthesized Molluscicidal and Larvicidal Selenium Nanoparticles: A New Strategy to Control Biomphalaria alexandrina Snails and Larvae of Schistosoma mansoni with an In Silico Study on Induced Oxidative Stress. [PDF]
J Fungi (Basel), 2022 Schistosomiasis is a tropical disease with socioeconomic problems. The goal of this study was to determine the influence of myco-synthesized nano-selenium (SeNPs) as a molluscicide on Biomphlaria alexandrina snails, with the goal of reducing disease ...

Genetic variation between Biomphalaria alexandrina snails susceptible and resistant to Schistosoma mansoni infection. [PDF]
Biomed Res Int, 2013 Much effort has been made to control schistosomiasis infection in Egypt. However, enduring effects from such strategies have not yet been achieved. In this study, we sought to determine the genetic variability related to the interaction between Biomphalaria alexandrina snails and Schistosoma mansoni.
