The production of chondroitinase enzyme was studied in a medium which contained . LYSINE These Gram negative, slightly curved bacilli cause infections in wounds, burns, and urinary tracts. Lab results indicated that the rapid test for infectious mononucleosis antibodies was negative. Alt 5 was given as a substitute for a gram-negative bacterium, due to no growth in original test tube (#122). In your procedure however, the preparation of the smear needs not be sterile but aseptically done to prevent unwanted materials/organisms on your slide and assuring that only the specimen you intend to examine is on your slide.
