Microbiological quality of Gölbaşi and Azapli lakes (Adiyaman) and determination of antibiotic resistance properties of isolates

In this study, microbial pollution levels and some physical parameters of Golbasi and Azaplı Lakes (Adiyaman) were investigated, and also identified bacteria and determined the resistance levels and multiple antibiotic resistance of bacteria isolated from lakes. For this purpose, five place were determined for taking water samples each of lakes. Water samples were collected at four different periods (December, march, july, october). Average water temperature, pH, dissolved oxygen and conductivity results shown that lakes have a high water quality according to in land water resources management. The presence of fecal streptococ was determined each of lakes and total coliform levels was high in station of Azaplı water canal 1 and 2 (>1100), total coliform levels were showed differences depending on periods in Golbasi lake. Results obtained from analyses have shown that 14 different species from 464 isolates were identified. Dominat bacteria was Aeromonas sobria . It was observed CZ, KF, CXM, ZOX, P and F resistance were observed generally high levels (up to %50) in isolates. Multiple antibiotic resistance (MAR) were determined from the rate of 89.5% of isolates in Golbasi lake and 94% of isolates in Azapli lake. In all of randomly selected fifteen isolates have multiple antibiotic resistance presence of plasmid was observed. The results indicated that Golbasi and Azapli lakes are good quality in terms of physical parameters, but in microbiologically polluted significantly
