We have studied the restricted antibiotic susceptibility tests for 180 strains belonging to mesophilic Aeromonas sp. isolated from stools samples. Strains has been identified as follows: A. caviae (64.6%), A. hydrophila (17.7%) and A. sobria (17.7%). Antibiotics tested were ampicillin (10 micrograms), carbenicillin (100 micrograms), cephalotin (30 micrograms) and colistin (10 micrograms), by means of agar diffusion tests (disk-plate). We identified four different patterns of antibiotic susceptibility. The most frequent pattern (pattern #1) (77.8%) is characterized by susceptibility only to colistin, and was predominant among A. caviae strains (80%). Pattern #2 (susceptibility to cephalotin and colistin) was found in 18.9% of strains, being predominant in A. sobria (88.2%). We confirm the higher susceptibility of A. sobria sp. to cephalotin as well as the possibility that these different patterns might be used as screening method for species identification among mesophilic group of Aeromonas.
我们对从粪便样本中分离出的180株嗜温气单胞菌属菌株进行了限制性抗生素敏感性试验。菌株鉴定如下：豚鼠气单胞菌（64.6%）、嗜水气单胞菌（17.7%）和温和气单胞菌（17.7%）。通过琼脂扩散试验（纸片平板法）检测的抗生素有氨苄西林（10微克）、羧苄西林（100微克）、头孢噻吩（30微克）和黏菌素（10微克）。我们确定了四种不同的抗生素敏感性模式。最常见的模式（模式#1）（77.8%）的特征是仅对黏菌素敏感，在豚鼠气单胞菌菌株中占主导（80%）。模式#2（对头孢噻吩和黏菌素敏感）在18.9%的菌株中发现，在温和气单胞菌中占主导（88.2%）。我们证实了温和气单胞菌对头孢噻吩的敏感性较高，以及这些不同模式可能用作嗜温气单胞菌属物种鉴定筛选方法的可能性。
