The Department of Parasitology of University of Granada (Universidad de Granada [http://www.ugr.es]), and the researcher Isabel Rodríguez González have submitted a thesis that analyses for the first time new isolated parasites: Leishmania and Trypanosoma in Peru, Mexico and Spain. These parasites are responsible for diseases such as Chagas – which affects at least 18 million people in South America – and Leishmaniasis – which affects around 12 million people throughout the world. The World Health Organization has recognised these diseases as a public health problem.
This study has compared these parasites with reference strains, by using biochemical and molecular techniques. Thanks to these techniques, the researcher was able to identify which groups these isolated parasites belong to.
No medical treatment
The researcher pointed out: “There is no specific treatment yet. Medicines that are used may have serious consequences. Their efficiency varies, because they are long and expensive treatments often associated with toxic effects.” Some species of these parasites need no treatment, others do.
“If we want to find a specific treatment, the first step we have to take is to correctly identify these species.” This is also of epidemiological value to understand parasite distribution, and is aimed at discovering specific control measures.
Another important feature of the study is the usefulness of one of the techniques used: PCR (Polymerase Chain Reaction). It is a relatively simple technique, cheap in comparison with others. PCR makes it possible to identify the isolated parasites in field studies.
The results of the study have already been published in some of the most important scientific journals in the field of Parasitology, such as Parasitology Research, Experimental Parasitology or FEMS Microbiology Letters.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
