NewsParasites of viruses drive superbug evolution
Researchers have discovered a previously unknown mechanism by which bacteria share their genetic material through virus parasites.
-
NewsMolecular biologists identify framework for understanding RNA editing in a disease-causing parasite
Researchers have determined the architecture of the molecular machines that harbour gRNA strands and allow those strands to engage mRNA in the single-celled, disease-causing parasite Trypanosoma brucei.
-
NewsResearchers use mass spectrometry to explore antimicrobial resistance
Researchers are using single-cell mass spectrometry to determine whether cells with persistent pathogens will also have less intracellular drug levels to potentially explain antimicrobial treatment failure.

NewsGene expression in apicoplast could be target for malaria treatment
Gene expression within the apicoplast, an organelle in the malaria parasite Plasmodium falciparum is regulated by melatonin in host blood, and intrinsic parasite cues, via a factor called ApSigma, a recent study reveals.
-
NewsCyanotriazole compounds can rapidly cure trypanosome infections in mice
Scientists have identified a class of cyanotriazoles (CTs), which exhibit potent trypanocidal activity and lead to rapid clearance of parasites both in vitro and in mouse models of Chagas disease and human African trypanosomiasis.

NewsResearchers reveal how Leishmania parasite uses immune cells as Trojan Horse
A new study found that the parasite targets a receptor on the surface of the neutrophil to gain access to the cell, and once inside the parasite resists the neutrophils’ pathogen-killing molecules.

NewsDrugs targeting malaria in Mozambique are still effective
The drugs used to treat and prevent malaria in Mozambique are still effective, according to a genomic analysis of drug resistance markers in Plasmodium falciparum, carried out by the Barcelona Institute for Global Health (ISGlobal) and the Manhiça Health Research Center (CISM).

NewsFeral cats shed more toxoplasmosis parasites in areas densely populated by humans
A new analysis suggests that wild, stray, and feral cats living in areas with higher human population density tend to shed a greater amount of the parasite that causes the disease toxoplasmosis.
-
NewsMolecule can block invasion of blood cells by malaria parasite
For the first time ever, a molecule able to prevent the invasion of blood cells by parasites of the genus Plasmodium, responsible for malaria, has been identified and described by scientists.

NewsRobotic vehicles fight dengue-carrying mosquitos in Taiwan sewers
A new study has shown the effectiveness of using an unmanned ground vehicle system to monitor sewers for Aedes mosquitoes and carry out eradication.
-
NewsDisabling sensor halts malaria parasite in its tracks
UNIGE scientists have identified a new type of molecular sensor that enables the malaria parasite to infect human cells or mosquitoes at just the right moment
-
NewsMalaria pathogen found in mummified soft tissue in Medici tomb
The pathogen of the deadliest form of the disease has been identified in mummified soft tissue belonging to members of the Florentine dynasty.
-
NewsBiological clocks of people and malaria parasites tick in tune
Research could pave the way to new anti-malarials that work by ’jet-lagging’ the parasites that cause the disease.
-
NewsWomen are more prone to repeat cases of toxoplasmosis eye disease
Women are more likely to experience recurrent cases of the Toxoplasma parasite, new research suggests.
-
NewsSymbiotic and pathogenic fungi may use similar tools to manipulate plants
Scientists have discovered that remotely related fungi are using a similar group of proteins to manipulate and live within plants.
-
NewsStudy uncovers how Leishmania parasite adapts so quickly to drugs
Scientists probing the parasite’s gene expression regulation during mRNA translation have discovered how it is able to preemptively and quickly adapt and respond to drug treatments.
-
FeaturesThe climate crisis and the spread of vector-borne disease
The effects of climate change could see future global outbreaks caused by mosquito-borne arboviruses expand their current geographical spread.

NewsEarly toilets reveal dysentery in Old Testament Jerusalem
A new analysis of ancient faeces taken from two Jerusalem latrines dating back to the biblical Kingdom of Judah has uncovered traces of a single-celled microorganism Giardia duodenalis – a common cause of debilitating diarrhoea in humans.
-
NewsPuppeteer fungus directs ‘summiting’ of zombie flies
Scientists have uncovered the molecular and cellular underpinnings behind the ability of the parasitic fungus Entomophthora muscae’s ability to manipulate the behaviour of fruit flies.

NewsSecond gene implicated in malaria chloroquine resistance evolution
How malaria parasites evolved to evade a major antimalarial drug has long been thought to involve only one key gene. Now, scientists have shown a second key gene is also involved in malaria’s resistance to the drug chloroquine.
