Parasitic infection describes the infection of a host with a particular parasite. Parasites are microorganisms that rely on other host organisms for their own survival. Many parasites do not cause any harm to their host, but some parasitic infections cause severe diseases, such as malaria.
Routine sampling of pregnant women at first antenatal care (ANC) visits could be used for malaria surveillance. Here, the authors compare the genetic structure of Plasmodium falciparum parasite populations between samples from first ANC users and children from the community in Mozambique, and show that it can inform about changes in transmission beyond epidemiological data.
Theileria parasites have evolved mechanisms to evade host cell defenses. Here, Villares et al use an anti-parasite drug to show how intracellular parasites sequester host eIF5A to escape elimination by autophagy pathways.
Sleeping sickness caused by African trypanosome parasites induces a chronic, and potentially lethal, infection in humans. Here, the authors uncover a conserved protein, Q586B2, playing an important regulatory role in Trypanosomatid infection establishment.
Parasitoid wasps are reared and released as biocontrol agents to manage aphids and protect crops. Here, the authors use genomes from 542 wasps to show that, in spite of wide scale release of low-diversity captive individuals, diversity in wild populations is maintained.
Resistance to chemotherapy for soil-transmitted helminth infection has been detected in veterinary settings but not yet in human infections. Here, the authors investigate the risk of resistance in humans and how it may change as a result of scaling-up preventative deworming programs.
Intestinal helminths can increase the lethality of a subsequent coinfection with neurotropic flaviviruses by activating tuft cells and type 2 immune mechanisms in the gut.
