ALMEIDA, Anna Christina de; RISTOW, Luiz Eduardo  and  BUELTA, Tânia de Toledo Martins. Microbiological and clinical characterization of "red leg" outbreaks in Minas Gerais, Brazil, and evaluation of in vitro bacterial effects of Vantocil IB^® for Aeromonas hydrophila. Cienc. Rural [online]. 2000, vol.30, n.4, pp. 661-664. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782000000400017.

With the objective of characterizating lhe ocurrence of "red leg" in Minas Gerais, Brazill, young and adult frogs which presented in theirpads and limbs hemorragie in the skin of the ventral region, incordination, high death rate in adults and hepatic abscess at necropsy, have been evaluated. In fragment culture ofdamage skin and abscess, Aeromonas. hydrophila hás been isolated and identified. The bactericidal effect of VANTOCIL IB^® was higher than that of potassium permanganate, as determinated by the minimal inhibitory concentration for isolated colonies.

Keywords : frogs; "red leg"; Aeromonas hydrophila; vantocil; biguanides.
