...reduce the algae's bacterial food supply, the scientists fumigated the grotto with an aerosol of powerful antibiotics (penicillin, streptomycin and kanamycin). Next, they tackled Palmellococcus itself. They found that a spray of formaldehyde mixed with detergent not only killed the algae-which gradually lost their color-but had no ill effect on the paintings themselves...
Last week the payoff was reported at a two-day Manhattan medical meeting: kanamycin, an antibiotic developed from a microbe found in K-2J, has won quick renown. Like all potent drugs, it has its disadvantages (it must usually be given by injection, and long-continued heavy dosage may cause some degree of deafness). But it seems worthy to rank with the tetracyclines, which, after penicillin (still queen of antibiotics), are now the most-used antibiotics...
Especially valuable is kanamycin's effectiveness against strains of microbes, notably Staphylococcus aureus, that are resistant to the older antibiotics and have caused terrifying epidemics in many U.S. hospitals. Kanamycin got its acid test in such an outbreak in Houston (TIME, March 31): of 36 infants who got it, 28 recovered, including eleven who had been considered hopeless cases...
Research physicians from a dozen U.S. medical centers reporting on their studies with more than 500 patients expressed hope that kanamycin will also prove effective against many urinary-tract infections (common, stubborn and dangerous), and against tuberculosis-though precise assay of its usefulness against TB will take years. Also offered was evidence that kanamycin (released for general prescription last month, trade-named Kantrex by Bristol Laboratories) may prolong life and ease pain in cirrhosis of the liver...
...many pneumonia deaths are suspected (though not yet proved) to have been caused by staph. To fight the guilty strains of germs-which are resistant to most widely used antibiotics-doctors are trying two new antibiotics not yet released for general use, vancomycin and one developed in Japan called kanamycin...
