Apr. 17—MOSES LAKE — Frank Zhao, a professor of plant pathology at Washington State University, spoke at the April 4 Fire Blight Webinar hosted by Michigan State University, providing an ...
Fire blight, also written fireblight, is a contagious disease affecting apples, pears, and some other members of the family Rosaceae. It is a serious concern to apple and pear producers. It is a serious concern to apple and pear producers.
Initially copper sprays were used for fire blight control in the 1930s but this method had limited success. [24] In the 1950s streptomycin and oxytetracycline showed high success in controlling fire blight in comparison to copper. Since then streptomycin sprayed two to three times during blooming phase has become the treatment of choice.
As human and bacteria both have ribosomes, streptomycin has significant side effects in humans. At low concentrations, however, streptomycin inhibits only bacterial growth. [18] Streptomycin is an antibiotic that inhibits both Gram-positive and Gram-negative bacteria, [19] and is therefore a useful broad-spectrum antibiotic.
Most clinical antibiotics were found during the "golden age of antibiotics" (1940s–1960s). Actinomycin was the first antibiotic isolated from Streptomyces in 1940, followed by streptomycin three years later. Antibiotics from Streptomyces isolates (including various aminoglycosides) would go on to comprise over two-thirds of all marketed ...

With an option to work in a pharmaceutic company or pursue a PhD, Schatz chose the latter. He rejoined Waksman's lab from where he received a PhD in 1945 with the thesis "Streptomycin, an Antibiotic Produced by Actinomyces griseus." [6] His PhD work led to the discovery of the first antibiotic, streptomycin, that is effective against ...
