| high frequency of hemolytic and cytotoxic activity in aeromonas spp. isolated from clinical, food and environmental in rio de janeiro, brazil. | molecular study of aerolysin and cytotonic enterotoxin genes by pcr and colony blot hybridization was performed in 117 strains of aeromonas spp. isolated from different sources. homogeneous distribution of these genes in a. hydrophila complex strains was observed. for a. caviae and a. sobria complex strains, aerolysin genes were more frequent than cytotonic enterotoxins genes. of 64 a. caviae complex strains, only one (1.5%) amplified the 451 bp product for the aer gene, however, the same primer ... | 2009 | 19347601 |
