Bacterias aisladas de las branquias del ostión japonés Crassostrea gigas, cultivado en Bahía Falsa, Baja California, México
SINCE THE LATE 70S, THE JAPANESE OYSTER, CRASSOSTREA GIGAS, HAS BEEN CULTURED IN BAHÍA FALSA, BAJA CALIFORNIA, MEXICO. NOWADAYS, THERE ARE 21 CULTURE COMPANIES INVOLVED IN THIS ACTIVITY. IN 1998, UNUSUAL MORTALITY EPISODES OF OYSTERS BEGAN TO OCCUR, REACHING UP TO 80% OF THE PRODUCTION. THESE MORTALITYÂ EPISODES HAVE BEEN RECURRED UP TO DATE AND, THE HYPOTHESIS OF A POSSIBLE PATHOGEN INVOLVED, SUCH AS A VIRUS, BACTERIA OR BOTH, REMAINS OPEN. THIS WORK SHOWS THE RESULTS OF A STUDY ON THE PHYSIOLOGICAL AND BIOCHEMICAL CHARACTERIZATION OF ISOLATED BACTERIA FROM GILL TISSUE OF OYSTERS RECOLLECTED DURING A MORTALITY EPISODE IN 2001. THREE COLONIES WERE ISOLATED, TWO OF THEM GREW IN TCBS SELECTIVE MEDIUM, FORMING YELLOW COLONIES, WHICH WERE IDENTIFIED AS BELONGING TO THE GENUS AEROMONAS. THE THIRD COLONY COULD NOT BE CULTURED OR IDENTIFIED. THERE ARE NOT RECORDS ON THE PATHOGENICITY OF AEROMONAS SPP. IN MOLLUSKS; HOWEVER, THEY HAVE BEEN REPORTED AS PATHOGENIC FOR FISHES AND REPTILES. IDENTIFICATION OF THE NOT CULTURED BACTERIA MUST BE CARRY OUT BY MOLECULAR METHODS.

IDENTIFICATION OF THE NOT CULTURED BACTERIA MUST BE CARRY OUT BY MOLECULAR METHODS. EL OSTIÓN JAPONÉS, CRASSOSTREA GIGAS, SE CULTIVA EN BAHÍA FALSA, BAJA CALIFORNIA, DESDE FINALES DE LOS AÑOS SETENTA. EN LA ACTUALIDAD EXISTEN 21 EMPRESAS DEDICADAS A ESTA ACTIVIDAD. A PARTIR DE 1998 SE COMENZARON A REGISTRAR MORTALIDADES INUSUALES DEL OSTIÓN, ALCANZANDO PORCENTAJES MAYORES AL 80% DEL TOTAL DE LA PRODUCCIÓN. ESTOS EPISODIOS DE MORTALIDAD SE HAN MANTENIDO DE FORMA MÁS O MENOS REGULAR Y LA HIPÓTESIS DE UN POSIBLE AGENTE PATÓGENO INVOLUCRADO, COMO UN VIRUS, UNA BACTERIA O AMBOS, PERMANECE VIGENTE. EN EL PRESENTE TRABAJO SE REGISTRAN LOS RESULTADOS DE UN ESTUDIO DE CARACTERIZACIÓN FISIOLÓGICA Y BIOQUÍMICA DE BACTERIAS AISLADAS DE TEJIDO BRANQUIAL DE OSTIONES RECOLECTADOS DURANTE UN EPISODIO DE MORTALIDAD EN 2001. SE AISLARON TRES COLONIAS DE BACTERIAS, DOS DE LAS CUALES CRECIERON EN EL MEDIO SELECTIVO TCBS FORMANDO COLONIAS AMARILLAS QUE SE IDENTIFICARON COMO BACTERIAS DEL GÉNERO AEROMONAS. LA TERCERA CEPA AISLADA NO SE PUDO CULTIVAR NI IDENTIFICAR. LAS ESPECIES DE AEROMONAS NO SE DOCUMENTAN COMO PATÓGENAS PARA MOLUSCOS, PERO SÍ PARA PECES Y REPTILES. POR OTRO LADO, LA IDENTIFICACIÓN DE LA COLONIA DE BACTERIAS DE DIFÍCIL CRECIMIENTO EN MEDIOS EMPLEADOS EN ESTE ESTUDIO, DEBE REALIZARSE MEDIANTE MÉTODOS MOLECULARES.
