Identifying bacterial contaminants throughout husbandry pool Artemia urmiana cysts in Artemia Research Center, Urmia

This research was conducted to evaluate the possible bacterial contamination on cysts of cultured Aretemia urmiana. Samples caught by using of 100 micron mesh sterile net from Artemia Research Center 's pounds. Then the samples were transferred in sterilized containers of bacteriology laboratory center. Of that center, then, separately crushed in mortar and 1 g of it was mixed with 9 CC pepton water. All samples were placed in incubator at 35-37 degree centigrades for 18-24 hours. Then, each sample was cultured and identified in general culture mediums agar and specific nutrient broth containing 3% NaCl. The results of experiment with gram painting, key morphological identification and etc., bacteria congaing Psudomonasaeroginosa, gram negative Coccii, Bacillus cereus, E. coli, Aeromonas hydrophila, Salmonella typhimorium, and Vibrio bacteria were observed in the Artemia cysts. These infections can be transmitted to aquatic consumers. Thus the cyst consumed in aquaculture should be disinfected with disinfection compounds and then could get packed.
