Jad, I sure hope this is merely a speed bump that " Q " has just encountered as they have some very neat POCT kits. Keep your eye on the BIG Gorilla ( Abbott Labs ) as I have heard rumblings they are getting very aggressive in the Rapid Screen markets. I follow Trinity Biotech fairly closely and will defer to Robert Busse on any "internal squabbling " at " Q " Dr. Alan Pronovost is just now assisting Trinity in getting several Uni-gold tests through the US FDA. Curious to hear what is happening at Quidel ?

I would be careful to assign too much value to anything that is posted on Yahoo, be it pro or con concerning QDEL. Messages on Yahoo are basically anonymous, and with anonymity comes irresponsibility. There may be any number of agendas being served by the tone and content of the messages there, coupled with a litany of highly enlightening posts that go like, "Quidel SUCKS!", and "Quidel is shit to work for", the value of information on that board is, at best, marginal. As to the particular post in question, it wouldn't surprise me in the least that there would be power struggles. What company doesn't have power struggles? The business community is rife with political intrigue. I don't think QDEL is being held down at all. Considering it is operating without a head and facing flat earnings, I'd say the share value has held up pretty well. --Randy

How Ulcer Bacteria Cause Disease Friday April 3 5:57 PM EST NEW YORK (Reuters) -- A new study shows how the bacteria Helicobacter pylori (H. pylori) can lead to ulcers and stomach cancer, and may help scientists learn how other bacteria cause disease. The study is reported in the Proceedings of the National Academy of Sciences. Half of the people in the world are infected with H. pylori, though most have few symptoms and may live with the bug for decades. But 10% to 20% of infected individuals will eventually develop ulcers or inflammation of the stomach, and 30% to 90% of stomach cancers are tied to H. pylori. In the study, Dr. Jeffrey I. Gordon from Washington University School of Medicine in St. Louis, Missouri, and colleagues inserted a human gene called Lewis b (Leb) into the stomach cells of mice and then infected the mice with H. pylori. The researchers discovered that the bacteria attached to the stomach linings of mice with Leb but not those without Leb, where the bug went into gastric mucus. When H. pylori went onto the stomach lining, the mice with Leb made antibodies to attack the bacteria. But the antibodies were similar to other cells already in the mice, so the animals' immune systems began to attack those cells as well as the bacteria. This caused an inflammatory response similar to chronic active gastritis found in people who have an active H. pylori infection. "This is a rather extraordinary example of a bacterium that can be relatively harmless in some people and cause cancer in others," Gordon said in a statement. "The challenge is to identify patients who are at risk for developing more serious disease."
