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
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.
An immune cell tangles with a protozoan parasite in a life-or-death struggle. The ribbon-like parasite is Trypanosoma brucei, a microscopic menace that causes African sleeping sickness. The parasite is transmitted by the bite of the tsetse fly. New research, published June 14, 2012 online by the journal Science, finds that once in the body, this parasite is well-adapted to give the immune system the slip.
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.
As referenced in the most recent episode of Triqinella. This Week in Parasitism, Dickson Despommier, This image of T. spiralis was taken by Despommier himself. The images in this collection, taken by Despommier, are free to use as long as you give him the appropriate credit.
SEM of Staphylococcus epidermidis cluster embedded in exopolysaccharide matrix. The Gram-positive bacteria S. epidermidis and S. aureus are the most common pathogens in hospital-acquired infections. The more recent combination of extraordinary virulence and multiple antibiotic resistance in community-acquired methicillin-resistant strains of S. aureus (CA-MRSA) poses an additional severe threat to public health.
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.
This transmission electron micrograph (TEM) revealed numerous hepatitis virions, of an unknown strain of the organism. In the United States, viral hepatitis is an important public health problem because it causes serious illness, it affects millions, and it has a close connection with HIV. There are five identified types of viral hepatitis and each one is caused by a different virus. In the United States, hepatitis A, hepatitis B and hepatitis C are the most common types.
