Abstract

In order to investigate and find out the bacterial community of hot spring waters in Eskişehir,

Turkey, 7 hot spring water samples were collected from 7 different hot springs. All samples were inoculated using four different media (nutrient agar, water yeast extract agar, trypticase soy agar, starch casein agar). After incubation at 50 ºC for 14 days, all bacterial colonies were counted and purified. Gram reaction, catalase and oxidase properties of all isolates were determined and investigated by BIOLOG, VITEK and automated ribotyping system (RiboPrinter). The resistance of these bacteria was examined against ampiciline, gentamisine, trimethoprime-sulphamethoxazole and tetracycline. As a result, heat resistant pathogenic microorganisms in addition to human normal flora were determined in hot spring waters (43-50 ºC) in investigated area. Ten different species belong to 6 genera were identified as Alysiella filiformis, Bordetella bronchiseptica, B. pertussis, Molexalla caprae, M. caviae, M. cuniculi, M. phenylpyruvica, Roseomonas fauriae, Delftia acidovorans and Pseudomonas taetrolens.

Abstract

Eskişehir/Türkiye’deki ılıca sularındaki bakteriyel topluluğun ortaya konulması ve incelenmesi için 7 ılıca su örneği 7 farklı ılıcadan toplanmıştır. Tüm örnekler dört farklı besi ortamına (nutrient agar, su-maya ekstraktı agar, triptik soy agar, nişasta-kazein agar) inoküle edilmiştir. 50 °C’de 14 günlük inkübasyondan sonra tüm bakteri kolonilerinin sayımı yapılıp saflaştırılmıştır. Tüm izolatların gram reaksiyonları, katalaz veoksidazözellikleri belirlenmişve BIOLOG, VITEK veotomatikribotiplendirme sisteminde (RiboPrinter) incelenmişlerdir. Bu bakterilerin ampisilin, gentamisin, trimetoprim-sülfametoksazol ve tetrasiklin antibiyotiklerine karşı dirençliliği incelenmiştir. Sonuç olarak normal insan florasına ilaveten ısıya dirençli patojenik mikroorganizmalar incelenen alandaki ılıca sularında (43-50 °C) belirlenmiştir. Altı genusa ait 10 farklı tür Alysiella filiformis, Bordetella bronchiseptica, B. pertussis, Molexalla caprae, M. caviae, M. cuniculi, M. phenylpyruvica, Roseomonas fauriae, Delftia acidovorans ve Pseudomonas taetrolens olarak tanımlanmıştır
