Abstract
Las adaptaciones desarrolladas por los microorganismos
antárticos frente a las extremas condiciones a las que se encuentran
sometidos hacen que estos sean considerados como una fuente potencial
de nuevos agentes antimicrobianos.
Se realizaron ensayos de antibiosis con cepas bacterianas y fúngicas
aisladas en una muestra de sedimentos marinos procedentes de Isla
Decepción, Antártida. A estos, se han sumado ensayos de antibiosis frente
a bacterias tipo de laboratorio. Los resultados reflejan que son los hongos
las potenciales fuentes de nuevos antimicrobianos.
Además, se estudiaron los antibiogramas de las cepas antárticas frente a
antibióticos de uso clínico. Los resultados sobre resistencias que se obtengan
en este estudio podrían servir como punto de partida para conocer el
grado de impacto de origen antrópico en la resistencia a antibióticos. A la
vista de los resultados, podemos decir, que la mayor parte de las cepas de
nuestro estudio son cepas resistentes a los antibióticos empleados.

Antibiosis essays were performed on bacterial and fungal strains isolated in a sample of marine sediments from Deception Island, Antarctica. To these, antibiosis essays against laboratory type bacteria have been added. The results reflect that fungi are the potential source of new antimicrobials. In addition, the antibiograms of Antarctic strains were studied against antibiotics for clinical use. The results on resistance obtained in this study could serve as a starting point to know the degree of anthropogenic impact XVII Congreso de Ciencias Veterinarias y Biomédicas 279 on antibiotic resistance. In view of the results, we can say that most of the strains of our study are resistant to the antibiotics used.
