Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, Volume 68, Issue 1, January 2026.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Immunoparasitological Study in Bilharzial Patients With or without Hepatitis C Virus in El-Beheira Governorate

Journal of High Institute of Public Health, 2007
Hepatitis C virus infection and schistosomiasis are common in Egypt. Coinfection is not uncommon. Little and quite controversial data are known about biochemical profile in these patients.

Opportunities and challenges for modelling epidemiological and evolutionary dynamics in a multihost, multiparasite system: Zoonotic hybrid schistosomiasis in West Africa [PDF]

, 2017
Multihost multiparasite systems are evolutionarily and ecologically dynamic, which presents substantial trans‐disciplinary challenges for elucidating their epidemiology and designing appropriate control.

Evaluation of Total Serum IgE Level and Associated Factors in Asthmatic Patients at the University of Gondar Hospital, Northwest Ethiopia: A Comparative Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 1, January 2026.
ABSTRACT Background and Aims Asthma is a chronic respiratory disorder with both genetic and environmental underlying risk factors. Allergic asthma, the most prevalent kind, is mostly ascribed to aberrant T helper type 2 (Th2) inflammation and is brought on by allergens.

Reduction of testosterone levels in Schistosoma haematobium- or Schistosoma mansoni-infected men: a cross-sectional study in two schistosomiasis-endemic areas of the Adamawa region of Cameroon

BMC Infectious Diseases, 2022
Background The incidence of schistosomiasis‐induced male reproductive dysfunction and infertility is probably underestimated compared to female genital schistosomiasis. This study aimed to investigate the impact of Schistosoma haematobium or S.

Characterization, cloning and immunogenicity of antigens released by transforming cercariae of Schistosoma mansoni [PDF]

, 2000
A schistosome infection is initiated when the parasite penetrates the skin of a susceptible host. Relatively large quantities of protein are released by transforming cercariae compared to later larval stages.

Sex in Immune Cells and Parasitic Diseases — A Complex Relationship

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Epidemiological studies consistently show that many parasitic diseases affect males more frequently than females. These disparities are multifactorial, arising partly from gender‐specific behaviors that influence exposure risk and health‐seeking practices, especially in low‐ and middle‐income countries. Increasing evidence also highlights that

Pulmonary involvement in Schistosomiasis mansoni [PDF]

Memórias do Instituto Oswaldo Cruz, 1987
The post-treatment pulmonary alterations were evaluated in patients (Study 1) and in mice (Study 2) infected with Schistosoma mansoni. Study 1: the patients were examined pre and post-treatment (with ora oxamniquine) and the following exams were performed: sputum for eosinophils and chest x-ray.

Characterization of Transcriptional, Epigenetic, and Phenotypic Plasticity and Discovery of Biomarkers in Acute and Chronic Murine Schistosomiasis Infection [PDF]

FASEB J
Workflow for discovering parasitological and molecular changes related to Schistosoma mansoni infection. ABSTRACT Parasites can induce changes in their hosts, favoring the success of the infection and its development at each stage of their life cycle.

One Health – an Ecological and Evolutionary Framework for tackling Neglected Zoonotic Diseases [PDF]

, 2015
Understanding the complex population biology and transmission ecology of multihost parasites has been declared as one of the major challenges of biomedical sciences for the 21st century and the Neglected Zoonotic Diseases (NZDs) are perhaps the most ...
