Equipment and materials in places open to public and in sport centres have caused to the community-acquired diseases and endanger the human health. In this study, it was aimed to determine the microorganisms in sport complexes threatening the human health and identify the protection methods. For the study, 111 samples were taken from different sport complexes, playgrounds, swimming pools and schools in Kirikkale. The samples were put into bloody EMB and Sabouraud Medium and wait in incubator of 37 degree. The samples were evaluated after 24, 48 and 72 hours. The reproduced samples were taken into account and the samples that reproduction was not seen were thrown after 72 hours. Microorganisms were determined as gram positive and gram negative. In the study, it was observed that there was production in 101 of 111 samples which were taken from the surfaces of equipment and materials in sport complexes and playgrounds. 112 microorganisms were produced from the samples that there was production. In the study, while the most seen microorganism group is Staphylococcus, 40 of the microorganisms belong to the group of Staphylococcus. As a result of the study, one of the microorganisms found in equipment and materials in playgrounds and parks was Staphylococcus aureus, and it was observed that it was sensitive to methicillin (MSSA) as a result of antibiogram. As these kinds of bacteria in the playgrounds were found in this study, it revealed the need of giving more importance to hygiene and prevention methods.
