İzmir ilinde çeşitli su kaynaklarındaki Caulobacter'lerin karakterizasyonu ve antibiyotik dirençlerinin incelenmesi

Caulobacter, uzantılı bakteriler grubunun farklı bir genusudur. Bu bakteriler, hayat döngüleri boyunca tek flajelli yüzücü hücre ve bir sapa sahip hareketsiz hücre formlarını sırayla oluşturmaktadır. Denizden ve kıyı bölgelerinden olduğu gibi topraktan ve tatlısulardan izole edilebilirler. Bu çalışmada, İzmir ilindeki 10 farklı su kaynağından alınan örneklerden 29 Caulobacter genusu üyesi izole edilmiştir. Yapılan mikroskobik incelemeler ve biyokimyasal testler sonucunda, 9 izolatın C. leidyi, 14’ünün C. variabilis, 6’sının C. intermedius olduğu belirlenmiş ve 7 farklı antibiyotiğin bu bakterilerin büyümesi üzerine etkisi tespit edilmiştir.

Characterizations of Caulobacters in different water sources in İzmir and investigation of antibiotic resistance of them

Characterizations of Caulobacters in different water sources in İzmir and investigation of antibiotic resistance of them. Caulobacter is a distinctive genus of prosthecate bacteria. During their life cycle these bacteria alternate between monoflagellated, swarmer cell and a nonmotile cell which has a stalk. They can be isolated from soil and freshwater as well as marine and estuarine locations. In this research, 29 members of Caulobacter genus from 10 different water sources which are located in Izmir region were isolated. At the end of the microscobic investigations and biocemical analyses, its observed that 9 strains belong to species C. leidyi, 14 strains belong to species C. variabilis, 6 strains belong to species C. intermedius and effects of the 7 different antibiotic on the growth of these bacteria were researched.
