“…As the water passes through the digestive tract other bacteria that escape the filtration at the gills are been eliminated by the digestive tract enzymes and those that could not be eliminated will find themselves at the intestine. The findings of this study did not agree with the findings of Gomez-Gil et al [48] who reported high prevalence of bacteria species in the hepatopancrea followed by intestine in healthy juveniles of Penaeus vannamei.…”

“…These results suggest that the components of shrimp immunity are closely correlated. The presence of bacteria in healthy shrimp is not surprising as bacteria have been found in the hemolymphs of other crustaceans, including horseshoe crab (42), blue crab (43)(44)(45), and penaeid shrimp (46). The interaction between crustaceans and the microorganisms present in their bodies, however, is not yet fully understood.…”

Background: Lysozyme is ubiquitous in many organisms and functions primarily in bacterial lysis. Results: The absence of lysozyme in shrimp resulted in the increase of bacteria in the hemolymph leading to mortality. Conclusion: Lysozyme is essential to shrimp survival particularly in regulating bacterial communities in the hemolymph. Significance: A clear understanding of the immune effectors in shrimp, such as AMPs, is vital in ensuring resistance against bacterial pathogens.

“…Tissues of healthy marine invertebrates usually harbor species-rich microbial communities (Prieur et al, 1990;Gomez-Gil et al, 1998;Romero et al, 2002;Gomez-Gil et al, 2010;King et al, 2012;Trabal et al, 2012;Wegner et al, 2013). This also applies to the hemolymph (Olafsen et al, 1993;Garnier et al, 2007, Wendling et al, 2014-the functional analog of blood in vertebrates (Bachere et al, 2004).…”

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

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.
