The aim of the study was to determine a participation of Aeromonas sp., having conjugation R plasmids, in a population of the bacteria present in purified urban sewage . In 1 ml of sewage 1.8 x 10(3) - 50 x 10(3) of Aeromonas sp., were found. The isolated strains belonged to the following genera: A. hydrophila, A. caviae, A. sorbia. All tested strains were sensitive to gentamicin, tetracycline, kanamycin and nalidixic acid. Among 186 strains of Aeromonas sp., two belonging to A. caviae genus transferred resistance to streptomycin to A. hydrophila and E. coli recipients on the other hand two strains of A. caviae transferred resistance to streptomycin exclusively to A. hydrophila recipient.
本研究的目的是确定具有接合R质粒的气单胞菌属细菌在净化城市污水中的细菌种群中的参与情况。在1毫升污水中发现了1.8×10³ - 50×10³个气单胞菌属细菌。分离出的菌株属于以下属：嗜水气单胞菌、豚鼠气单胞菌、温和气单胞菌。所有测试菌株对庆大霉素、四环素、卡那霉素和萘啶酸敏感。在186株气单胞菌属细菌中，两株豚鼠气单胞菌将对链霉素的抗性转移给了嗜水气单胞菌和大肠杆菌受体，另一方面，两株豚鼠气单胞菌仅将对链霉素的抗性转移给了嗜水气单胞菌受体。
