Significant Progress in the Study of African Freshwater Snails Over the Past 260 Years

Ecology and Evolution, Volume 15, Issue 2, February 2025.
Globally, freshwater ecosystems are threatened, and studies estimate rapid degradation compared with terrestrial and marine ecosystems. Like most other tropical regions, Africa still has far to go regarding discovery and documentation. Using a systematic review process, we evaluated freshwater African snail studies.

When One Global Invasion Hides Another—Cryptic Interspecific Invasion in Freshwater Gastropods

Diversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Cryptic invasions are an understudied phenomenon among species invasions, especially in freshwater invertebrates. We study the gastropod family Physidae, including the global invaders Physella acuta and several enigmatic Stenophysa species, their phylogenetic relationships and the presence of native species among African Physidae. We infer

The Effect of Physicochemical Properties of Water Bodies on Schistosomiasis Intermediate Host Snails’ Distribution in Sub‐Saharan Africa: A Systematic Review

Advances in Public Health, Volume 2025, Issue 1, 2025.
Background: Schistosomiasis, a disease affecting 800 million people in sub‐Saharan Africa (SSA), is transmitted through direct contact with infected snail intermediate hosts, in freshwater water bodies. Environmental, climatic and physicochemical properties of the water bodies can interfere with parasite development, reproduction, snail growth and ...

An Ethnobotanical Survey and Pharmacological and Toxicity Review of Medicinal Plants Used in the Management of Obesity in the North Central Zone of Nigeria

Journal of Obesity, Volume 2025, Issue 1, 2025.
Introduction: Obesity is increasing worldwide. Due to the unavailability of affordable obesity drugs in most parts of Nigeria, many overweight and obese people rely on medicinal plants to manage obesity. Thus, the aim of this study is to document medicinal plants traditionally used in the treatment and management of obesity in the North Central Zone of

Diet of schistosome vectors influences infection outcomes

Ecosphere, Volume 15, Issue 11, November 2024.
Abstract Resource availability can alter infection outcomes through its impact on host immunity and on parasite reproduction. On one hand, enhanced nutrition could favor immunity, limiting the parasite, and on the other hand, it could favor establishment and reproduction of the parasite.
