[CAMP factor for the differentiation among Aeromonas species]. / Factor CAMP para la diferenciación en especies de Aeromonas.

The CAMP factor technique, described by Natale Figura as a presumptive method for the differentiation of the species hydrophila, sobria and caviae, was applied to 80 Aeromonas strains isolated from children under 5 years with acute diarrheic disease. The typical phenomenon was seen in aerobiosis and anaerobiosis conditions in 10 strains, which were classified as Aeromonas hydrophila. In aerobiosis conditions/alone, it was observed in 20 strains, which were identified as Aeromonas sobria. It was not observed in either of the incubation conditions above mentioned in 50 of the remaining strains, which were identified as Aeromonas caviae. The advantages of applying this new technique is emphasized.
