...biological weapons. “Even if we don’t know which pathogen it is, we still can tell which family or which group it’s in, so if someone engineers a virus that has never been seen, we will have hints that it’s close to something that is known,” he said. Further studies may eventually help doctors track the p...

Flies too Have Immune Memory!

... a primitive first-line, nonspecific response to a pathogen "invader." The other arm found in higher organisms is adaptive immunity, which has a memory that retains an internal record of contact with an invader and - employing T and B cells - springs into action once it encounters the same invader again. This...

Discovery Leads to Way to Curb Anthrax Effect

.... There is essentially no free iron available to a pathogen in a normal host. All of the host’s iron is functioning in enzymes or heme containing proteins, or is safely stored, with a small amount in transit bound to a protein called transferrin. Pathogenic bacteria like anthrax must tap into our normal iron ...
