Asexual Giardia lineage spreads across hosts: new insights
Overview: A new chapter in Giardia’s history An asexual lineage of Giardia, the microscopic parasite responsible for diarrhea worldwide, appears to be spreading across different animal hosts more than researchers previously recognized. A WEHI-led team in Australia has uncovered evidence that this particular Giardia lineage can infect a broader range of species, a finding with…

Asexual Giardia Lineage Spreads Across Hosts at Survival Cost
Introduction: a parasite’s surprising strategy A recent study led by Australian researchers has shed light on how a particular asexual lineage of Giardia, a parasite known for causing diarrhea, manages to infect a broader array of animal hosts. The discovery highlights how parasites can evolve strategies that trade long-term survival for wider transmission, with important…

Asexual Giardia lineage spreads across hosts at a cost to survival
Unveiling a remarkable spread: the asexual Giardia lineage Giardia, a microscopic parasite long known for causing diarrhea and gastrointestinal distress, has a new chapter to add to its story. In a study led by researchers from the Walter and Eliza Hall Institute of Medical Research (WEHI) in Australia, scientists describe how a specific, asexual lineage…

Long-Term molecular surveillance of Cryptosporidium and Giardia in wildlife in protected drinking water catchments
Overview of a long-term molecular survey in protected catchments Maintaining safe drinking water from natural catchments requires understanding protozoan pathogens in wildlife. This longitudinal study analyzes Cryptosporidium and Giardia from 8,695 fecal DNA samples collected across 16 years (2009–2024) in Melbourne, Australia’s protected catchments. Using PCR-based sequencing and phylogenetic analyses, researchers identified 12 Cryptosporidium species/genotypes…

Long-term molecular surveillance of Cryptosporidium and Giardia in wildlife in protected drinking water catchments: Insights from Melbourne’s catchments
Overview of the study Maintaining safe drinking water from protected catchments requires understanding the protozoan parasites that can bypass conventional water treatment. This long-running molecular surveillance project investigates Cryptosporidium and Giardia in wildlife across Melbourne’s catchments, applying SSU-based sequencing to identify species and genotypes directly from faecal DNA samples. Between 2009 and 2024, researchers analyzed…
