Trypanosoma brucei infection induces fat breakdown, but this strategy benefits the host. 

The findings could help researchers understand why some individuals are more vulnerable to deadly Chagas disease.

New techniques to quantify what lived in and on preserved animals throw light on how parasite abundance has changed over time.

A method for culturing the infectious stage of the Plasmodium lifecycle could increase malaria vaccine production efficiency by tenfold, study authors say.

The parasite appears to make infected wolves less risk-averse, potentially influencing the behavior of packs.

Immune cells get a lot of shine when it comes to fighting infection, but it turns out that fat might be just as important for removing parasitic invaders.

A study traces the effects of a mite outbreak from the earth to the heavens.

Laboratory experiments find that Toxoplasma, Cryptosporidium, and Giardia can congregate on microplastic beads and fibers, suggesting they might make their way into and around the world’s oceans by hitching rides on tiny bits of trash.

Her achievements included developing a roadmap to tackle neglected tropical diseases.

Comparing the genomes of modern pathogens with those of cryopreserved strains from several decades ago shed light on the evolution of coffee wilt disease outbreaks in Africa.

Several research groups have found that Toxoplasma gondii infection can ramp up antitumor immune responses in mice. Can the single-cell parasite be used to develop safe treatments for humans?

Scientists find human DNA preserved in lice cement from the heads of South American mummies.

NIH researcher Andaleeb Sajid discusses her study’s finding that ticks were unable to feed on vaccinated guinea pigs, preventing transmission of the pathogen that causes Lyme disease.

Tumor cells missing a critical protein enter neighboring cells to sap their nutrients, then exit those hosts as intact cells, possibly primed to metastasize. Other scholars say it’s too early to know this for sure.

When conservationists relocate species, they don’t always account for the pathogens hitching a ride, and the consequences of introducing them to a new environment.

Scientists suspect the gall-forming protist Maullinia hitches a ride on kelp rafts to reach new host populations at far-flung sites.

The University of Washington parasite ecologist aims to understand how humans have changed the diversity and abundance of the enigmatic and misunderstood organisms.

A single-celled organism has an energy-producing enzyme with unique features.

An enzyme blocker is highly effective at treating intestinal parasitic infection in mice.
