Staphylococcus epidermidis, pacifiers


The opportunistic bacteria that thrive on pacifiers is Staphylococcus epidermidis, generally produces biofilms and a causative agent of common nosocomial infections. Withal, the study was formulated in order to detect and determine the presence of Staphylococcus epidermidis on pacifiers of infants which guarantees no safety to the health of the infants. The researchers have used a descriptive design in order to identify the presence of Staphylococcus epidermidis and collected eight (8) pacifiers that had undergone the swabbing method, streak plate technique, incubation, manual plate count method, and biochemical tests. Through Gram staining method and biochemical tests such as the catalase test, coagulase test, and novobiocin susceptibility test, the results showed that there were identified three (3) Staphylococcus epidermidis out of eight (8) samples. Data showed that the presence of Staphylococcus epidermidis on pacifiers was 37.5%, still a high susceptibility of infants getting harmed and illed.
