...1940s, when penicillin came into wide use, it was seen as the miracle drug to save the world from pneumococcal pneumonia, an infection that then had a mortality rate as high as 85%. But as more and more antibiotics came into use, nature fought back, creating more resistant bacteria. When first used, penicillin was nearly 100% effective against the most prevalent Staphylococci aureus that spread hospital-related infection among patients. Today the drug is far less effective. Both tetracycline and penicillin, once used to cure gonorrhea, now have a failure rate of more than 20% against certain strains. For years...
...overuse of wonder drugs is caused not only by indiscriminate prescriptions. An astonishing 40% of all the antibiotics used in this country are put into livestock feed to make animals grow fatter. As a result, bacteria resistant to antibiotics are accumulating rapidly in the environment. In 1977 the Food and Drug Administration tried to limit such stock-feed boosters, but under heavy pressure from drug companies, Congress simply ordered more research...
...that orders up the production of VP3. A molecular fragment containing these instructions was then spliced into a plasmid, or small circular collection of DNA, taken from an E. coli bacterium. Then the plasmid and its "recombined" DNA were inserted back into E. coli. Not only did the recipient bacteria begin cranking out VP3, but all their offspring reproduced the protein as well...
...four Herriot books are bolts cut from the same Scottish tweed, carefully interweaving the local patois (Owt a gurt cow wi' nawbut a stone in t'kidney) and technical jargon ("You can get hypertrophy of the rumenal walls and inhibition of cellulose-digesting bacteria with a low pH"). Each volume has become increasingly formulaic. But it is Herriot's original formula, an unfailing blend of exotica-for The Lord God Made Them All, a recollection of trips to Russia and Turkey-and accounts of extraordinary happenings to ordinary people and creatures. Volume IV of the tetralogy offers...
...bleeding vessels are quickly sewed and any holes in the intestine are clamped. The first objective is to halt the loss of blood to keep the patient from slipping into shock-the most immediate danger in abdominal wounds. The other is to prevent the seepage of infection-causing bacteria into the abdominal cavity...
