The inhibitory effect of Saccharomyces cereviisiiae filtrates on the growth of biofilm-forming Staphylococcus aureus

Abstract

The study included an investigation of the inhibitory ability of yeast isolates
6 p.a. (obtained from commercial sources
imported) on the growth of Staphylococcus aureus isolated from diseased cases
different, as it was possible to obtain (01) isolates of the bacterium A. Sa’az {Hartmeh: K.
All these isolates were subjected to culture, microscopic and biochemical examinations and were diagnosed
using the 714662 system. The ability of the isolates to form a biofilm was tested using
Two methods are the center of the solid Congo Red ( ) APM and
Accurate calibration dishes method (17) 0 L Mohan, has
The results showed that the second method was the most sensitive in investigating membrane formation
biofilm, where (60%) of the isolates showed their ability to form a biofilm in a manner
(H) and (83.3%) by the method of (7) and the other isolates did not produce a biofilm.
Regarding the sensitivity test, these isolates showed variation in their resistance to antibiotics
The biosynthesis is under study, with the exception of the similarity of all isolates in their resistance to pathogenesis
L and 21007710, with a percentage of 100%, and its sensitivity is 100% for an antidote.
