El trabajo se realizó en el Laboratorio de Biología de la Universidad Nacional Autónoma De Alto Amazonas en la ciudad de Yurimaguas con el propósito de establecer si era posible identificar mediante el método de Tinción Gram la presencia de agentes patógenos que fueran capaces de ocasionar daños a la salud del ser humano como consumidor directo. Para ello se obtuvo 10 ejemplares de Anodontites trapesialis (tumbacuchara) de un mercado local, esto nos indicaba de con seguridad que dichos ejemplares eran destinados al consumo humano directo. De cada ejemplar se tomaron 3 muestras (boca, estomago e intestino) haciendo un total de 30 muestras a evaluar. Durante la experimentación solo se pudo observar bacilos Gram Positivos en muestras de boca de algunos ejemplares sin poder identificar a nivel genérico ni especifico lo cual es indicativo de que el método de Tinción De Gram no es el adecuado para la identificación de flora bacteriana del tracto digestivo de tumbacuchara

“…También se han detectado bacterias predominantemente Gram negativas en la hemolinfa de ejemplares adultos de A. purpuratus, comportándose como microbiota normal (García-Tello et al 2002). Además, se ha caracterizado la población de bacterias cultivables presentes en los cultivos larvales y post-larvales de A. purpuratus, encontrándose una mayor abundancia de los géneros Pseudoalteromonas, Bacillus, Marinobacterium, Alteromonas y Vibrio en larvas (Godoy et al 2011) y del género Vibrio en post-larvas (Avendaño et al 2001).…”

Excessive fishing effort has led to overexploitation and depletion of major benthic fisheries in Chile, so it has been encouraged cultivation of major overexploited benthic resources in controlled environments, mainly those which are not possible to collect seeds from environment. In this review, the current knowledge on bacteriology associated with shellfish farming in controlled systems in Chile, including both aspects associated with development of infectious diseases of bacterial aetiology as well as the use of microorganisms to reduce mortality of cultured species, is described. The majority of bacteriological studies in Chilean shellfish culture were done in the Chilean scallop, Argopecten purpuratus and were related to identifying pathogens isolated from mass mortalities occurred in larval and/or juvenile cultures and the verification of their pathogenic activity performing bioassays under controlled condition bioassays. There are also a large number of studies on bacteria exhibiting inhibitory activities against shellfish pathogenic and their protective effects under controlled conditions. Despite the above, still are required more studies to know the structure and dynamics of the microbiota associated to mollusk culture, bacterial pathogens and molecular elements encoding for their pathogenicity.

The present situation and future projections regarding shellfish culture in Chile are analysed. Production has increased exponentially, mainly of the 'Chilean mussel' Mytilus chilensis (Hupe) and the 'northern scallop' Argopecten purpuratus (Lamarck). At present, seven species are cultured, two of which were introduced. The total invertebrate production corresponding to cultures has increased from 1.6% to 38% over the last 15 years. The effects of the following factors on present and future levels of shellfish culture in Chile are discussed: disease, fouling, borers, red tide and environmental variations caused by the cultures themselves. Potential culture of approximately 70 commercially endemic species not only constitutes an economic option, but also favours their conservation. more than 50 publications in ISI journals on ecological aspects of aquatic resources (marine and fresh water), and aquaculture.

Bacterias en la hemolinfa de Argopecten purpuratus (Lamark, 1819) (Bivalvia: Pectinidae)

Abstract: Twenty three strains of bacteria were isolated from the hemolymph of Argopecten purpuratus. Our results point out to the predominance of asporogenous Gram-negative rods. We suggest that the presence of these bacteria in the hemolymph is a natural phenomenon.
