imarães S Abstract Giardia duodenalis is one of the most important and widespread gastrointestinal parasites in the world. Despite its relevance as a causative agent of diarrhea, asymptomatic giardiasis occurs frequently, especially in low resources settings in which children are exposed to many risk factors. Based on microscopic examination and the polymerase chain reaction (PCR) amplification and sequencing of beta-giardin (bg), triose phosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes, we assessed G. duodenalis occurrence and genetic diversity in isolates of children attending a daycare ce...

Abstract SUMMARYWhile flagella have been studied extensively as motility organelles, with a focus on internal structures such as the axoneme, more recent research has illuminated the roles of the flagellar surface in a variety of biological processes. Parasitic protists of the order Kinetoplastida, which include trypanosomes and Leishmania species, provide a paradigm for probing the role of flagella in host-microbe interactions and illustrate that this interface between the flagellar surface and the host is of paramount importance. An increasing body of knowledge indicates that the flagellar membrane serves a mult...

(Monash University) Australian Scientists have shown that an anti-parasitic drug already available around the world can kill the virus -- effectively eradicating all genetic material of the virus within 48 hours. Scientists from Monash University in Melbourne showed that a single dose of the drug, Ivermectin, could stop the SARS-CoV-2 virus growing in cell culture -
