The Research on the Presence of Beta-Lactamase Enzyme of Streptococcus faecalis Isolated From White Cheese (Turkish with English Abstract)
Abstract
Twenty Streptococcus faecalis were isolated from the sample of white cheese which had been obtained from different dairies. In the study of iodometric test method 2 of 20 Streptococcus faecalis were negative beta-lactamase. Later, the presence of beta-lactamase enzyme in 2 beta-lactamase positive Streptococcus faecalis was confirmed by using. Chromogenic Cefalosporin Test (Nitrocefin). Besides, antibiotic sensitive test with Penicilline-G was applied. Two Streptococcus faecalis which were determined beta-lactamase positive by the method of Chromogenic Cefolosporin Test (Nitrocefin) were found to be resistant against Penicillin-G.The result was supported to the test of beta-lactamase.

Beyaz Peynirden İzole Edilen Streptococcus faecalis’lerin Beta-Laktamaz Enzim Varlığını Gösteren bir Araştırma
Abstract
Çeşitli süt işletmelerinden sağlanan beyaz peynir örneklerinden 20 Streptococcus faecalis izole edilmiştir. İodometrik Test yöntemi ve beta-laktamaz enzimi ile çalışılan 20 Streptococcus faecalis’in 2’si beta-laktamaz pozitif bulunmuş, geriye kalan 18 S. faecalis ise beta-laktamaz negatif çıkmıştır. Daha sonra 2 beta-laktamaz pozitif S. faecalis’in Kromojenik Sefalosporin Test (Nitrosefin) ile beta-laktamaz enzim varlığı kontrol edilmiştir. Ayrıca, penisilin-G ile antibiyotik duyarlık testi yapılmıştır. Kromojenik Sefalosporin Test (Nitrosefin) yöntemiyle de beta-laktamaz pozitif çıkan 2 S. faecalis, penisilin-G’ye karşı dirençli olduğu tespit edilmiştir. Bu sonuç beta-laktamaz testlerini desteklemiştir.
