Brazil launches 'good mosquitoes' to fight Dengue fever

Rio De Janeiro - Brazilian scientists, based in Rio de Janeiro, have released thousands of mosquitoes infected with bacteria that suppress dengue fever.

Blood-sucking parasite and quail decline connection

In the summer of 2010, the Rolling Plains of West Texas expected a bumper crop of quail. By October, they nearly had vanished. A new study shows the cause to be a blood-sucking parasite.

Fighting malaria by targeting genes

A new approach to preventing malaria by knocking out parasite's genes has been proposed. Biological engineers have demonstrated that a new genome-editing technique can disrupt a single parasite gene with a success rate of up to 100 percent.

Bird parasite alert issued

House Finch eye disease, a bacterial parasite, is infecting a wide range of species, though most do not show signs of illness, according to a new report. The disease is primarily a respiratory infection and appears on birds as conjunctivitis.

Rise in drug resistant malaria

Washington - A new study indicates that drug-resistant malaria is spreading in South East Asia, and that it has now reached the Cambodia-Thailand border.

Oldest ever parasite egg found

The discovery of a schistosomiasis parasite egg in a 6200-year-old grave could provide the first evidence that agricultural irrigation systems in the Middle East contributed to disease burden.

How do lemurs fight infection?

Next-generation genome sequencing technology is enabling researchers to catalog 150,000 antibodies found in a single species of lemur that seems uniquely susceptible to parasitic infection.

Deadly Asian toad settles in Madagascar

A group of scientists has urged the Madagascan government to take up arms against the Asian common toad, which is a poisonous relative of the infamous cane toad that has now gained a foothold on the island.

Protein discovery could help prevent malaria deaths

Stockholm - Malaria can be mild or deadly. However, there is no way to tell which patients are at risk of developing more dangerous forms of the disease. New research suggests that different proteins affect the seriousness of the disease.

How does the immune system protect children from malaria?

Some children who live in regions of the world where malaria is common can mount an immune response to infection with malaria parasites. Scientists have investigated why this response takes place.

New suspect for the decline of honeybees

A virus that causes blight in plants may contribute to the catastrophic decline of honeybee colonies. This could be one of the main reasons why bee populations are in decline around the world.

Parasites used to control locust populations

A Chinese study suggests that migratory locusts are less likely to aggregate into crop-devastating swarms when infected by a parasite.

Searching for a new way to halt malaria

A research team have identified a way to stop malaria parasites from multiplying. It is hoped that this could become the basis of a new treatment.

Mexican bees at risk

Bees in Mexico have become susceptible to parasite - the Varroa acari – which is leading to a reduction in bee populations in the country.

Malaria cases in U.S. at 40-year high

The number of malaria cases in the US has reached a 40-year high, with 1,925 cases reported in 2011 — the highest number since 1971.

Symposium wants greater innovation towards eliminating malaria

A Malaria Consortium symposium has highlighted the need for increased innovation as part of malaria elimination efforts, during the Sixth Multilateral Initiative on Malaria (MIM) Pan-African Malaria Conference in Durban.

Breakthrough in parasitic worm infection

Scientists have made an important step forward in finding a potential treatment for a gastrointestinal parasitic infection that affects over a billion people worldwide.

Brain eating amoeba found in water supply where boy died

Tests carried out by the the Centers for Disease Control and Prevention of a Louisiana parish's water supply found that it contained the deadly brain eating parasitic amoeba.

Step taken towards sleeping sickness cure

Scientists in Belgium have taken a step towards creating a protein-based cure for the most common form of global sleeping sickness.

Canadian oyster killing parasite isolated

Some tiny, elusive parasites that have plagued oysters from British Columbia to California have been detected and identified for the first time.

Infected bees leave the hive altruistically

Scientists have established that sick and infected bees leave their hives voluntarily, as an act of altruism, rather than being driven out by the healthy bee population.

U.K. cautious about spending more to tackle global malaria

A number of world governments have announced an increase funding globally for the fight against malaria. However, the U.K. is more cautious, arguing that countries in receipt of aid need to reform before more money is given.

Tick disease risk to domestic cats

Veterinarians are warning pet owners in the U.S. of the increased risk of a disease called Bobcat fever, which is carried by ticks, and is a risk to cats.

Chimps contract malaria at the same rate as people

Chimpanzees have been studied for the first time relation to the incidences of malaria. The conclusion is that chimps can contract malaria just as easily as people and have similar survival rates if untreated.

Bacteria used to combat malaria

A new study has shown that transmission of malaria via mosquitoes to humans can be interrupted by using a strain of the bacteria Wolbachia in the insects.

International research team uncovers clues to parasitic disease Special

An international team of scientists in Seattle, Wash., U.S., and Cordoba and San Martin, Argentina, have uncovered a surprising new role for one type of immune cell in controlling the parasite Trypanosoma cruzi.

Tapeworm DNA hold clue for anti-parasitic drug

A new study of tapeworm DNA provides clues as to the possible targets on which currently licensed drugs could act against the parasite.

Blood-sucking parasite named Marley in homage to Reggae singer

Researchers from Arkansas State University have discovered a parasitic crustacean which infects fish in the coral reefs of the eastern Caribbean. They named it after Bob.

Mosquitoes engineered to be unable to transmit malaria

Scientists have bred mosquitoes which are unable to infect people with the malaria parasite. They hope that such populations of malaria-free mosquitoes can enter the ecosystem and help to curb the population of malaria-carrying mosquitoes.

A new branch of life?

A new organism has been discovered in a pile of slime buried in a lake in Norway. The organism is so unusual that the scientific team which has examined it genetically are declaring that it should have its own location on the tree of life.
