A disfiguring parasitic infection, common in the tropics, has now found a home in Texas and Oklahoma and is expanding its range in the U.S. The parasite, Leishmania mexicana, is transmitted by tiny ...

Once thought to be a danger largely reserved for travelers, a flesh-eating parasite known as Leishmania mexicana is now likely spreading locally through some sand flies native to the southern U.S., a ...

Leishmaniasis belongs to the class of neglected tropical diseases (NTDs) that particularly affect people in the poorest tropical regions of the world. NTDs are less studied and therapeutically ...

A skin-inhabiting species of Leishmania found in Panama in the tropical porcupine, Coendou rothschildi, is considered new and described as Leishmania hertigi sp. n. L. hertigi is differentiated from ...

A parasite capable of causing a disfiguring skin disease may be endemic in Texas and present in other southern states, according to the Centers for Disease Control and Prevention. From 2005 to 2019, ...

The vaccine prevents infection spread by inducing an immune response in dogs with visceral leishmaniasis. This response prevents the parasite from being transmitted to the insect vector. This means ...

Finnish and French scientists have revealed how the actin cytoskeleton in cells is controlled in an evolutionarily distant, pathogenic Leishmania parasite. The results also provide tools to fight ...

Leishmaniasis is a tropical disease affecting a growing number of people worldwide. Each year, between 700,000 and 1 million new cases are reported. Caused by a protozoan parasite of the genus ...

WE must apologise for two errors in the note on the behaviour of cultures of Leishmania in P. papatasii (NATURE, Jan. 8, p. 48). Sandfly No. 172 was not laboratory bred but was caught in Jerusalem, ...

In the first barcoding survey of sand flies in Panama, scientists have identified 20 sand fly species from Barro Colorado Island. Two species carried Leishmania naiffi, a parasite that causes ...

Eukaryotic cells respond to DNA damage by activating damage checkpoint pathways, which arrest cell cycle progression and induce gene expression. We isolated a full-length cDNA encoding a 49-kDa ...
