Farmed fish with parasites: impact on wild fish stocks
'Fish farming is often proposed as a solution to diminishing stocks of wild fish. Sadly, many parasites are threatening the future of aquaculture' [by depleting fish stocks], write Jo Cable and Phil Harris, of Cardiff and Nottingham Universities, in the August issue of Biologist. A wide range of invertebrates can live on, or in fish before they... view more... (2003-08-01)
Purifying parasites with light
Researchers have developed a clever method to purify parasitic organisms from their host cells, which will allow for more detailed proteomic studies and a deeper insight into the biology of organisms that cause millions of cases of disease each year. view more (2008-09-15)
Study of malaria parasites reveals new parasitic states
A team led by scientists at MIT and Harvard University and supported in part by the National Institute of Allergy and Infectious Diseases, a component of the National Institutes of Health, collected blood samples from 43 P. falciparum-infected malaria patients in Senegal who were suffering from a range of malaria symptoms. view more (2007-11-29)
Researchers find natural section favors parasite fitness over host health
Why do parasites harm their hosts? Classic evolutionary theory predicts that parasites become more virulent because they must transmit themselves between hosts, yet scientists have found little data to support this idea, until now. view more (2008-05-13)
Malaria Parasites Develop in Lymph Nodes
In the first quantitative, real-time imaging study of the travels of the malaria parasite Plasmodium through mammalian tissue, researchers at the Pasteur Institute in Paris found the parasites developing in an unexpected place: the lymph nodes. view more (2006-01-23)
Different strategies underlie the ecology of microbial invasions
Infectious disease can play a key role in mediating the outcome of competition between rival groups, as seen in the effects of disease-bearing conquistadors in the New World-or, on a much smaller ecological scale, the ability of bacteria to spread their viruses to competing bacteria. view more (2006-10-24)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Passenger Screening Advised To Cut Risk Of Importing Drug-Resistant Malaria To Africa
Imported resistance has rendered ineffective the two affordable malaria drugs which have been the mainstay of malaria treatment in Africa for forty years, according to experts writing today in the journal Science. Scientists from the London School of Hygiene and Tropical Medicine and colleagues from institutions in the USA, South Africa and... view more... (2004-08-16)
What gives us sunburn protects crayfish against bacteria
The production of melanin gives us sunburns, but it also helps invertebrate animals to encapsulate attacking fungi and parasites. view more (2007-09-25)
How mosquitoes could teach us a trick in the fight against malaria
The means by which most deadly malaria parasites are detected and killed by the mosquitoes that carry them is revealed for the first time in research published today (5 March) in Science Express. The discovery could help researchers find a way to block transmission of the disease from mosquitoes to humans. view more (2009-03-06)
Study shows that parasites form the thread of food webs
Scientists have discovered that parasites are suprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences. view more (2006-07-13)
Slightly stressed carp succumb easily to parasite
Researchers from Wageningen have discovered that slightly stressed carp are much more susceptible to parasites than unstressed carp. All of the laboratory carp which were taken out of the water for one minute a day, died from parasitic attack. Only 40% of the carp who did not undergo the light stress treatment died from the parasites. The... view more... (2002-09-11)
A connected world gives viruses the edge
That's one conclusion from a new study that looked at how virulence evolves in parasites. view more (2009-05-28)
Fresh Hopes For Treatment Of Malaria In Africa (p 1218)
Despite the large number of deaths caused worldwide by AIDS, tuberculosis, and diarrhoeal diseases such as cholera, the biggest infectious-disease killer is still malaria, especially in Africa. Efforts to eradicate the carrier of malaria, a mosquito, have been only partly successful. The standard treatment for malaria has, for many years, been... view more... (2001-10-10)
Study finds role for parasites in evolution of sex
What's so great about sex? From an evolutionary perspective, the answer is not as obvious as one might think. view more (2009-07-07)
Researchers block the transmission of malaria in animal tests
By disrupting the potassium channel of the malaria parasite, a team of researchers has been able to prevent the malaria parasites from forming in mosquitoes and has thereby broken the cycle of infection during recent animal tests. view more (2008-06-10)
Parasites trigger healthy eating in caterpillars
Some parasites trigger their own destruction by altering their hosts' behavior, researchers at The University of Arizona and Wesleyan University report in Nature. view more (2005-07-29)
Sea cucumber protein used to inhibit development of malaria parasite
Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research out today (21 December) in PLoS Pathogens. view more (2007-12-21)

Tracking membranes of rupturing blood cells sheds light on malaria infection
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides. view more (2005-09-22)
