Abstract :
Antibiotics are substances produced by a living organism that are effective
in inhibiting or destroying the growth of other organisms. In principle, the
sensitivity test of an antibiotic is the first step in determining disease-causing
bacteria that can show resistance or knowing the ability of antibiotics to inhibit
bacterial growth in vitro, so that their potential for treatment can be determined.
Antibiotic sensitivity test was carried out using the Kirby-Bauer method on
bacterial cultures of 3 species, namely Staphylococcus aureus, Staphylococcus
epidermidis, and Staphylococcus saprophyticus with the technique used by
antibiotic disc diffusion according to Mc Farland standard no.5. The culture
medium used Mueller Hinton Agar (MHA) with Cefoxitin 30µl antibiotic disc
type which was incubated at 37ºC for 24 hours. The results of the inhibition zones
formed were measured with a ruler or caliper and interpreted based on the 2020
Clinical and Laboratory Standards Institute (CLSI) standards.
This research method uses secondary data collection taken from sources of
scientific journals, scientific papers or research thesis with the data analysis
technique used is descriptive analysis method.
The results of the Cefoxitin 30µl antibiotic sensitivity test to
Staphylococcus sp bacterial cultures showed that the results were sensitive or
bacterial isolates could be inhibited with the recommended and determined dose.
