A long-standing mystery of how a protein displayed on the surface of malaria parasites called "TRAP" interacts with human host cells has now been found.

Describing a species is a serious undertaking. In the case of T. acutus, Coats and his collaborators documented its microscopic life cycle, conducted extensive DNA analysis and unearthed scientific papers dating back to 1873—when parasitic dinoflagellates were first noted by German scientist Ernst Haeckel.

Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A National Science Foundation-funded study identifies the parasite's specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds. The study marks the first time a genetic link has been clearly established between the Toxoplasma strains in felid hosts and parasites causing fatal disease in marine wildlife. The study's results highlight how infectious agents like Toxoplasma can spread from cat feces on land to the sea, leading to detrimental impacts on marine wildlife.

A drug used to treat parasite infections at fish farms can contaminate the surrounding environment and threaten local wildlife, a new study shows. Following a week-long treatment at a Norwegian salmon farm, the authors found concentrations of an anti-sea-lice drug that were high enough to kill some crabs, shrimps and lobsters. However, they suggest the drug is not likely to pose a risk to humans.

Methods for removing parasites and in particular ectoparasites of vertebrates, in particular of mammals, and compositions for the implementation of this method.Methods for removing parasites of vertebrates, and in particular arthropods, mainly insects and Arachnida, wherein an effectively parasiticidal amount of a compound of formula (I) ##STR1## in particular of fipronil, is administered to the animal via an administration route which makes possible systemic distribution and good absorption.

A transmission line is provided in which a first portion of the transmission line is configured to be connected to a source, and a second portion of the transmission line is configured to be connected to a load. A capacitive element is coupled to the transmission line and is configured to compensate for an impedance difference between the load and at least one of the source or the transmission line, at a frequency within a frequency bandwidth of the load. A difference between an internal capacitance of the first portion of the transmission line and the second portion of the transmission line substantially matches the capacitance of the capacitive element.

The Ohio State University Moritz College of Law welcomes three dynamic professors to its faculty this fall: Micah Berman, Efthimios Parasidis, and Dakota Rudesill.

“We are thrilled to add these three emerging scholars to our already distinguished faculty. They represent the tradition here at Moritz of hiring exceptional teachers whose scholarship and instruction draw from a wealth of practical experience and focus on making a difference,” said Dean Alan C. Michaels, the Edwin M. Cooperman Professor of Law. “Additionally, Professor Berman and Professor Parasidis will be instrumental in greatly strengthening the college’s footprint in the growing health law field.”

The life cycle of malaria parasites in both their mammalian host and mosquito vector consists of multiple developmental stages that ensure proper replication and progeny survival. The transition between these stages is fueled by nutrients scavenged from the host and fed into specialized metabolic pathways of the parasite. One such pathway is used by Plasmodium falciparum, which causes the most severe form of human malaria, to synthesize its major phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine. Much is known about the enzymes involved in the synthesis of these phospholipids, and recent advances in genetic engineering, single-cell RNA-Seq analyses, and drug screening have provided new perspectives on the importance of some of these enzymes in parasite development and sexual differentiation and have identified targets for the development of new antimalarial drugs. This Minireview focuses on two phospholipid biosynthesis enzymes of P. falciparum that catalyze phosphoethanolamine transmethylation (PfPMT) and phosphatidylserine decarboxylation (PfPSD) during the blood stages of the parasite. We also discuss our current understanding of the biochemical, structural, and biological functions of these enzymes and highlight efforts to use them as antimalarial drug targets.
