Tropical diseases encompass all diseases that occur solely, or principally, in the tropics. In practice, the term is often taken to refer to infectious diseases that thrive in hot, humid conditions, such as malaria, leishmaniasis, schistosomiasis, onchocerciasis, lymphatic filariasis, Chagas disease, African trypanosomiasis, and dengue.
Each year, about 2 million people contract leishmaniasis, a parasitic disease transmitted by the bite of a sand fly. The cutaneous form of the disease results in disfiguring skin ulcers that may take months or years to heal and in rare cases can become metastatic, causing major tissue damage.
Many infectious diseases are one and done; people get sick once and then they are protected from another bout of the same illness.
Gambian sleeping sickness - a deadly parasitic disease spread by tsetse flies - could be eliminated in six years in key regions in the Democratic Republic of Congo, according to new research by the University of Warwick.
I think innovation is one of those rather slippery terms that means different things to different people. First of all, I would make a distinction between innovations that are essentially about a new, physical product and innovations that are more to do with services or processes.
Boosting a protective protein to stabilize blood vessels weakened by malaria showed improved survival beyond that of antimalarial drugs alone in pre-clinical research.
Researchers at the University of Georgia are working to find the fastest way possible to treat and cure human African trypanosomiasis, long referred to as sleeping sickness. By working to improve chemical entities already tested in human clinical trials, they hope to have a faster route to field studies to treat the disease using drugs that can be administered orally to patients.
The first global-scale genetic study of Salmonella Enteritidis bacteria, which is a major cause of blood poisoning and death in Africa and food poisoning in the Western World, has discovered that there are in fact three separate types.
People infected with a parasitic worm called Wuchereria bancrofti in areas where HIV is endemic may be more likely to acquire HIV than people who are not infected with the worm, according to a new study in southwest Tanzania, published in The Lancet.
Lesions on arms and legs, deformed faces - yaws is a tropical disease that infects the skin, bones and cartilage. It is caused by the bacterium Treponema pallidum subspecies pertenue
Griffith University tropical disease researchers have joined together with a host of international laboratories to advance drug discovery for major topical diseases through the creation and testing of the Malaria Box.
Professor Albert Descoteaux of INRS-Institut Armand-Frappier Research Centre and his team have discovered novel virulence strategies employed by the Leishmania parasite.
Some autoimmune diseases and persistent infections are characterized by high levels of antibodies in the blood. But what are the causes of this hypergammaglobulinemia? A team headed by INRS's Professor Simona Stäger has successfully identified the mechanisms triggering the phenomenon.
A new and inexpensive technique for mass-producing the main ingredient in the most effective treatment for malaria, artemisinin, could help meet global demands for the drug, according to a study to be published in the journal eLife.
The U.S. Food and Drug Administration today approved Vaxchora, a vaccine for the prevention of cholera caused by serogroup O1 in adults 18 through 64 years of age traveling to cholera-affected areas. Vaxchora is the only FDA-approved vaccine for the prevention of cholera.
If an infectious disease outbreak or an attack using an agent such as anthrax were to occur in Chicago, it most likely first will be noticed in emergency rooms throughout the city. Swift identification of the cause of an incoming patients' illness could be crucial to public health and safety personnel being able to intervene in time to save lives.
Wellcome Trust Sanger Institute scientists show how the parasite responsible for the neglected tropical disease Black Fever (visceral leishmaniasis) can become resistant to drug treatment. Studying the whole genomes of more than 200 samples of Leishmania donovani revealed that the addition of just two bases of DNA to a gene known as LdAQP1 stops the parasite from absorbing antimonial drugs.
For the first time, genome sequencing has been carried out on Chlamydia trachomatis (C. trachomatis), a bacteria responsible for the disease Trachoma - the world's leading infectious cause of blindness, according to a study in Nature Communications.
The world's first vaccine for a disease that causes misery for millions in Africa could be tested within five years.
Researchers at the Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California, San Diego have entered into a research collaboration with Janssen Research & Development, LLC, one of the Janssen Pharmaceutical Companies of Johnson & Johnson, to identify new therapeutic targets for Chagas disease, a parasitic infection that is the leading cause of heart failure in Latin America.
Treating multidrug-resistant tuberculosis (MDR TB) with regimens that include a greater number of drugs may improve outcomes, and baseline drug susceptibility testing (DST) could identify drugs with the greatest likelihood of success, according to a paper published this week in PLOS Medicine.
