WebNon–slime–producing strains were sensitive to all the tested antibiotics with a probability of 0001 < P < 001. There was no direct relationship between antibiotic sensitivity and phage type, although a non–typable strain was more often resistant to seven or more antibiotics than a typable one (005 < P <01). WebFor identification of Staphylococcus saprophyticus we have used disk-diffusion test for sensitivity to novobiocin.
