More people than just me immediately thought of Michael Crichton’s The Andromeda Strain, in which a deadly pathogen is brought to Earth from space.
"[Phages] are specific to a particular bacterial strain, so researchers will have to isolate and culture a phage for every potential coral pathogen, which isn't feasible."
And therefore you've got a lot of hosts available to exchange a pathogen, which is one of the processes by which viruses and bacteria evolve and acquire mutations. "www. loe.org" Bacteria are able to develop antibiotic resistance when exposed to low doses of drugs over long periods of time.
Called chikungunya, from an East African tribal word describing the contorted postures of its pain-wracked victims, the pathogen has been the focus of intense scientific interest ever since a 2006 outbreak on the island of La Reunion in the Indian Ocean infected about 266,000 people, killing 260 of them.
If the pathogen is a virus the phagocytes can't destroy hot cells.
Long-spined sea urchins were once extremely common off the coasts of Bermuda but after some pathogen, which is still a mystery to the science community, attacked theses creatures in 1983 their sightings have decreased a notable amount.
For vaccines, identification of conserved epitope among variants of a pathogen is a winning strategy to make functional vaccines.
Carried by animals like rats and dogs, the pathogen is usually a problem that arises during widespread flooding.
The pathogen is a few orders of magnitude larger than any other known virus, which has prompted a number of delays in its research.
The researchers revealed that SopB, at first, works within the external membrane of the cell, called the plasma membrane, to coax the cell into taking in the pathogen, which is then encapsulated within a tiny bubble-like compartment called a vesicle.
