Occurence and antibiotic susceptibility of motile aeromonas spp. of untreated well water

Ankara'dan toplanan içme suyu olarak kullanılan kuyu suları hareketli Aeromonasların varlığı yönünden analiz edildi. Bu çalışmada 166 kuyu suyu incelendi ve toplam 66 hareketli Aeromonas izole edildi. 40 A. hydrophila (% 60.60), 7 A. caviae (10.60 %), 19 A. sobria (% 28.78) izole edildi. Suşlarm çoğunluğunu A. hydrophila oluşturmaktaydı. Aeromonas suşlarının tür tayininde oksidaz, hareket, vibriostatik ajana (O/ 129) karşı duyarlılık, fermentasyon ve glikozdan gaz üretimi, sistemden H2S oluşumu, esculin hidrolizi ve KCN besiyerinde üreme gibi testler en etkili minimal testler olarak kullanıldı. Aeromonas suşları hemolitik aktivite ve antibiyotik duyarlılık yönünden test edildi. Aeromonas suşlarının 66 adedi (% 100) ampisilin ve eritromisine dirençli bulunurken bütün suşlar ciprofloksazin , sefazolin.sefixim, seftriakson, trimetoprim ve sulfametoksazol duyarlı bulundu.

Kuyu sularında hareketli aeromonas varlığı ve antibiyotik duyarlılığı

Drinking untreated water samples collected from Ankara, Turkey were analysed for the presence of motile Aeromonas species. In this study, 166 of untreated water samples were examined and total of 66 motile Aeromonas were isolated . A. hydrophila, A. caviae and A. sobria were present in all wells investigated, forty (60.60 %) A. hydrophila, 19 (28.78 %) A. sobria, 7 (10.60 %) A. caviae were isolated in water samples. The most of the strains isolated were A. hydrophila. minimal tests such as oxidase, motility, sensitivity to the Vibriostatic agent 0/129, fermentation, and gas production from glucose, H2S production from cysteine, esculin hydrolysis and growth in KCN broth were sufficient to classify the majority of Aeromonas strains into species.Aeromonas strains were tested for haemolytic activity, and antibiotic susceptibility. All of the 66 Aeromonas strains, study were resistant to ampicilline and erytromicin,but susceptible to ciprofloxacin, cefazolin, cefixime, ceflriaxone, trimetoprim and sulphamethoxazole and gentamicin.
