Shrimp becomes voracious cannibal through parasite infection

A new study suggests that parasites can trigger cannibalism in certain species. In the study, a parasite was found to trigger cannibalism in a shrimp and also made the shrimp hungrier for food.

Potential antimalarial drug made from algae

Scientists have used algae to produce a malaria parasite protein. When the algae-produced protein is paired with an immune-boosting cocktail, studies showed generated antibodies in mice were able to eliminate a mosquito infection.

Oyster infection rates increase at night

Oysters that reside in shallow waters around the world are prone to a parasitic disease. This is because nutrient pollution there runs high and oxygen levels invariably plummet to zero at night.

Little risk of malaria making a species jump

If the goal of eliminating the most dangerous malaria-causing parasite is achieved, will another type associated with a different species take its place?

New understanding with anti-malarial drug resistance

London - Researchers have identified mutations associated with resistance to afrontline antimalarial drug called artemisinin. This is part of the fight back against anti-malarial drug resistance.

Big fall in Guinea Worm Disease cases

New York - Only 126 Guinea worm cases were reported worldwide in 2014, according to the campaign body The Carter Center. This is down from 148 cases officially reported in 2013. This means that this disease is edging closer to extinction.

New compound shows anti-malaria promise

New York - A newly developed anti-malarial compound can trigger the immune system into rapidly destroying red blood cells infected with the malaria parasite and, at the same time, leave healthy blood cells intact.

Dracunculiasis cases decline globally

Some rare good news on the global health front. Only 148 dracunculiasis cases were reported in 2013 (the lowest annual total ever) and only four endemic countries remain. So, what is this parasitic disease?

Tapeworm lives in man's brain for four years (video)

London - A man who suffered with headaches and seizures for four years finally found out why: a rare tapeworm was living in his brain. The parasite has now been removed by medics.

Chagas disease emerging as U.S. public health threat

Chagas disease - a stealthy parasitic infection that can lead to severe heart disease and death, is spreading in the U.S. Scientists argue that policy makers need to treat the issue seriously.

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.
