HIV drug resistance is becoming a major threat to China's fight against HIV/AIDS, according to researchers.

The genome of a strain of extremely drug-resistant TB has been sequenced by South African scientists, and could aid future diagnosis.

Rural South Africa will see a large increase in extensively drug-resistant tuberculosis in the next five years without intervention.

Researchers say the use of second-line TB drugs in South Africa without drug susceptibility testing led to increased drug resistance.

Adding the antibiotic moxifloxacin to a TB drug combination could reduce treatment to just four months, say researchers.

A human trial of HIV gene therapy and new drugs hold hope for treatment, say scientists at an international HIV conference.

Scientists have developed a faster, cheaper method to screen for drug-resistant HIV, an increasing problem in resource-poor countries.

Scientists in Ghana have found that the parasite that causes river blindness is becoming resistant to the disease's only treatment.

Occurrence of extensively drug-resistant tuberculosis in India is twice that of the United States, according to new research.

Indian researchers have found a mechanism of drug resistance in leishmaniasis parasites, and suggest an effective way to reverse resistance.

Plague could easily develop drug-resistance and become a major health threat, warn scientists.

Chinese researchers have shown that direct reinfection, not poor treatment, is the biggest culprit in the spread of drug-resistant TB.

Scientists have developed a highly sensitive method to identify the drug resistance of different strains of HIV.

Researchers warn that TB resistant to multiple drugs is more widespread than thought, making better treatment regimes an urgent priority.

An international study says a strain of typhoid fever resistant to several antibiotics is spreading, suggesting the need for new vaccines.

A cheap and readily available antibiotic could relieve the severe symptoms of elephantiasis, say researchers.

Researchers have developed a new class of 'hybrid' molecules aimed at overcoming drug-resistant malaria.

A therapy that the WHO recommends for people with both HIV and TB could increase the spread of drug-resistant TB, say researchers.

Fears that GM crops could spread their drug resistance to bacteria that threaten human health seem unfounded, say scientists.
