Dispersin' Escherichia coli all over the gut
...aggregative Escherichia coli (EAEC) is an emerging pathogen
thatcauses endemic and epidemic diarrhea in developing and industrializedcountries. The bacteria stick to the surface of the cells lining the gut andrelease specific toxins that cause the cells to "open the floodgates" anddramatically increase secret...

Scientists decipher genetic code of malaria parasite
... Genetic Code The malaria parasite's success as a pathogen
depends partly on its ability to evade elimination by the human immune system. Gardner said the genome analysis identified about 200 parasite genes that produce proteins involved in that elaborate evasion. Previous research had shown that, during th...
