“…Salinity is recognised as one of the chief barriers to microbial communities (Bouvier & del Giorgio 2002, Troussellier et al 2002, Crump et al 2004. Vibrio populations are strongly influenced by environmental conditions, including temperature, sa linity, pH and nutrient availability (Lee et al 2001, Armada et al 2003, Eiler et al 2006, Martinez-Urtaza et al 2008, Turner et al 2009). Although no natural deaths were observed in the natural bivalve populations during this study, the environmental conditions in the 2 sampling locations were suitable for the growth of Vibrio spp.…”

“…In our bath infection experiments, temperature changes and hypoxic stress were included to mimic environmental changes because they have been implicated in bivalve deaths (Soletchnik et al 1999, Lee et al 2001. In this disease model, deaths only occurred when animals were infected with a high concentration of bacteria in adverse environmental conditions.…”

Widespread and large-scale mortalities of bivalve molluscs significantly affect their production. A number of pathogens have been identified as the primary causes of death in oysters or clams, especially bacteria of the genus Vibrio. We evaluated the occurrence, seasonality and infectivity of Vibrio strains associated with natural mussel (Mytilus galloprovincialis) populations. In particular, different isolates of V. splendidus and V. aestuarianus were analysed because they were associated with major oyster mortalities in areas where mussels are cultured without presenting mortalities. The presence of both Vibrio spp. was analysed bimonthly in mussels, water, sediment, plankton and other associated fauna from 2 sites in Galicia (NW Spain), the region with the highest mussel production in Europe. Environmental factors were also considered. The pathogenicity of different Vibrio isolates was analysed by performing experimental infections in mussels with strains isolated from the field. Results showed that Vibrio populations were mainly influenced by changes in water temperature and salinity. V. splendidus was dominant during the warm months and V. aestuarianus was predominant throughout the cold season. The sediment was the most important natural reservoir for bacteria. Experimental infections showed the extreme resistance of mussels to bacterial pathogens. Isolates of V. splendidus and V. aestuarianus were only moderately pathogenic for mussels in intramuscular infections and bath infections, and mortalities only occurred when animals were infected with a high bacterial concentration in adverse environmental conditions (hypoxia and 25°C). Although the pathogenicity of the Vibrio strains isolated from the wild was low for mussels, their potential risk for other bivalves cannot be ignored.

Hemolymph microbiome of Pacific oysters in response to temperature, temperature stress and infection

2014

Microbiota provide their hosts with a range of beneficial services, including defense from external pathogens. However, host-associated microbial communities themselves can act as a source of opportunistic pathogens depending on the environment. Marine poikilotherms and their microbiota are strongly influenced by temperature, but experimental studies exploring how temperature affects the interactions between both parties are rare. To assess the effects of temperature, temperature stress and infection on diversity, composition and dynamics of the hemolymph microbiota of Pacific oysters (Crassostrea gigas), we conducted an experiment in a fully-crossed, three-factorial design, in which the temperature acclimated oysters (8 or 22 1C) were exposed to temperature stress and to experimental challenge with a virulent Vibrio sp. strain. We monitored oyster survival and repeatedly collected hemolymph of dead and alive animals to determine the microbiome composition by 16s rRNA gene amplicon pyrosequencing. We found that the microbial dynamics and composition of communities in healthy animals (including infection survivors) were significantly affected by temperature and temperature stress, but not by infection. The response was mediated by changes in the incidence and abundance of operational taxonomic units (OTUs) and accompanied by little change at higher taxonomic levels, indicating dynamic stability of the hemolymph microbiome. Dead and moribund oysters, on the contrary, displayed signs of community structure disruption, characterized by very low diversity and proliferation of few OTUs. We can therefore link short-term responses of host-associated microbial communities to abiotic and biotic factors and assess the potential feedback between microbiota dynamics and host survival during disease.
