Some of the most overlooked diseases around the world are parasitic infections, especially those caused by a kind of parasite called helminths. The group includes hookworms and schistosomes, among others. These worms, which live inside their host, are especially common in developing countries. As we hear from health reporter Rose Hoban, a new study found that if you're infected with one, you're probably infected with others, too.

Ezeamama says it's vital that health officials in poor countries systematically address both the parasitic infections and the conditions that lead to children being infected with different kinds of parasites at once.

Treatment for the parasitic illness schistosomiasis is more effective if children have a snack before receiving the drug praziquantel.

Carolan wanted to learn how the organisms did that. So he studied the liver proteins of the two genetically-different mice. He and his team found that the liver cells of resistant mice had more copies of a protein than the mice that were more likely to be infected. The proteins create a chemical which the researchers believe could be toxic to the parasitic cells. But they are not sure.

More than one billion people in 80 countries are at risk of contracting lymphatic filariasis, known as elephantiasis, which is transmitted by mosquitos infected with parasitic filarial worms. The worms lodge in the lymphatic system, causing accumulations of lymph fluid that lead to massive swellings of limbs, usually the feet.

The altered mosquitoes produce higher than normal levels of the immune system protein, Rel2. That activates a host of anti-parasitic molecules which, in turn, launch an all-out attack on the malaria parasite.

But the latest findings may stimulate research into cures for the parasitic illnesses.
