Schistosoma mansoni parasite. In 2009 researchers from the UT Health Science Center San Antonio and other institutions crack the genetic code of Schistosoma mansoni, a flatworm that can live up to 10 years on average in humans. The parasite is endemic in many tropical areas of the world. #getuv #viqua
Invisible Residents. The Human Microbiome Project has spent two years surveying bacteria and other microbes at different sites on 242 healthy people. The chart below hints at the complex combinations of microbes living in and on the human body.

erythrocytesand bananas? deceivingly (thanks to the strange color choice), those two tropical fruits are actually blood cells infected with Plasmodium falciparum, the most deadly of five protozoan parasites known to cause malaria in humans with an incidence of approximately 300 million cases per year, mostly in sub-saharan Africa, malaria is the second most common cause of death worldwide (TB is top), claiming between 1.5 and 2.7 million lives each year it is estimated that 3000 children
Colorful killers. A new vaccine protects mice against parasites that cause leishmaniasis. A vaccine could save tens of thousands of lives every year. Scientists report that they have used snippets of DNA to spur mice to fight back against parasites responsible for the illness, an approach they hope to soon begin testing in people. Leishmaniasis is caused by microscopic parasites of genus Leishmania; 20 different species can sicken humans, hits poor residents of tropical countries hardest.
Malaria hope: Bacteria that make mosquitoes resistant
Researchers have found a strain of bacteria that can infect mosquitoes and make them resistant to the malaria parasite. The study, in the journal Science, showed the parasite struggled to survive in infected mosquitoes. Malaria is spread between people by the insects so it is hoped that giving mosquitoes malaria immunity could reduce human cases.
A colorized scanning electron micrograph of Mycobaterium tuberculosis, the bacteria that cause TB. Tuberculosis, commonly known as TB, is a contagious and an often severe airborne disease caused by a bacterial infection. TB typically affects the lungs, but it also may affect any other organ of the body. It is usually treated with a regimen of drugs taken for 6 months to 2 years, depending on the type of infection.
2.7-million-year-old fungus found deep under seafloor
2.7-million-year-old fungus found deep under seafloor - Science The story of life on Earth keeps getting stranger. Researchers report they've discovered dormant algae and a thriving community of carbon-chomping fungus deep beneath the ocean floor in 2.7-million-year-old mud.
