A cheap vaccine developed in India against rotavirus could add substantially to protection against diarrhoea.

Genome sequencing has revealed surprising new malaria parasites in Cambodia that are resistant to artemisinin, the frontline drug treatment.

Researchers have detected fine genetic changes to a dengue virus strain that can increase disease severity in the future.

The Leishmania parasite uses a sugary secretion to outwit the human immune system and resist antimony drugs, say researchers.

Newly discovered markers that appear to be linked to a hard-to-treat form of malaria could aid efforts to eliminate the disease before it can spread.

Scientists have modelled if the release of GM mosquitoes would lead a drop in dengue-transmitting mosquitoes, but further tests are needed.

A new diagnostic method can transform the management of a diarrhoea caused by a common bug.

Strains of rotavirus earlier found only in animals are now infecting human beings.

A second strain of the Japanese encephalitis virus prevalent in East and South-East Asia is now being reported from India.

New strains of the HIV1- C subtype are rapidly gaining in prevalence in India.

A recent strain of Salmonella is targeting the weakened immunity of HIV positive people in Sub-Saharan Africa, says a study.

Research capacity in infectious and non-infectious diseases, which affect millions of Africans, has been boosted by a multi-million dollar fund.

The results of two GM mosquito trials, in Brazil and the Cayman Islands, show up to a 90 per cent drop in dengue mosquito populations.

Dubai scientists hope their first GM camel, to be conceived later this year, will eventually make drug production in the region more affordable.

A study of two communities in northern Peru has revealed that a significant proportion have developed immunity to the rabies virus.

A newly developed test can quickly and reliably detect drug-resistant leishmaniasis.

French and US scientists have produced a GM mosquito whose immune system is capable of disabling or killing malaria parasites.

Mutations in chikungunya may hold clues to how the virus contantly adapts to mosquito vectors, a new study reports.
