Studies were conducted on the improvement of A. culicicola identification. This species is phenotypically very similar to A. veronii biotype sobria, A. sobria, and A. allosaccharophila. The sequences of 16S rDNA of A. culicicola isolates show the highest similarity with A. jandaei, A. veronii, and A. caviae. Digestion of 16S rDNA PCR product with Alul and Mbol restriction endonucleases allowed discriminating A. culicicola from all other Aeromonas species with the exception of A. jandaei. Additional digestion of 16S rDNA PCR product with BceAI showed a possibility of distinguishing A. jandaei from A. culicicola.
