In this study, we investigate the potential activity antibiotic in vitro of strains the marine bacterioneuston isolated from rocky litoral pools in Montemar Beach, Bay of Valparaiso, Chile. Were isolated 71 strains antagonic to Staphylococcus aureus ATCC 11632. Twentyfive strains producing strongly inhibitory substance were tested against 15 know ichthiopathogenic bacteria.

En este estudio, se investigó el potencial de actividad antibiótica in vitro de cepas nativas de bacterioneuston marino aisladas de las pozas intermareales de Montemar, Bahía de Valparaiso, Chile. Se aislaron 71 cepas neustónicas antagonistas a Staphylococcus aureus ATCC 11632. Veinticinco de ellas, productoras de sustancias fuertemente inhibitorias, fueron evaluadas por su antagonismo frente a una colección de 15 bacterias ictiopatógenas. Aplicando métodos clásicos para bacterias marinas, se caracterizaron fenotípicamente orientados a la identificación. Los resultados de antibiosis indican que la totalidad cle las ictiopatógenas en prueba son susceptibles a la actividad inhibitoria de las cepas neustónicas, siendo V anguillarum NCMB 2133, V ordalii 84/2559 y V tubiashii EX1 las más sensibles. Entre las cepas aisladas del neuston se identificaron miembros de los géneros Vibrio spp. (28%), Flavobacterium spp. (12%), Alteromonas-Marinomonas (12%), Pseudomonas spp (8%) y Micrococcus spp, (4%). Nueve cepas (36%) no fueron identificadas. Los resultados de actividades inhibitorias frente a ictiopatógenos sugieren que dichas cepas o sus productos pudieran ser útiles en actividades de cultivos intensivos de maricultura de peces, moluscos y crustáceos.Universidad Nacional Mayor de San Marcos, Facultad de Ciencias Biológicas1998-06-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/832010.15381/rpb.v5i1.8320Revista Peruana de Biología; Vol. 5 Núm. 1 (1998); 047 - 064Revista Peruana de Biología; Vol. 5 No. 1 (1998); 047 - 0641727-99331561-0837reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/8320/7245Derechos de autor 1998 Jorge León, Patrico Gracía-Tellohttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/83202020-05-26T18:18:23Z |
