“…The presence of V. cholerae in the HP of apparently healthy penaeids matches results published by Suzita et al (15). According to the latter, V. cholerae occurs in salt and brackish water, freely or associated with zooplankton and algae, and may adhere strongly to the digestive tract of marine organisms.…”

ORIGINAL Microbiota of ABSTRACTObjective. The present study aimed to investigate the presence of vibrios in the hepatopancreas of cultured shrimp. Materials and methods. Vibrios from the hepatopancreas of fifteen samples of five specimens each, of apparently healthy Pacific white shrimp (Litopenaeus vannamei) were isolated, identified and quantified. Results. The vibrio density ranged from 430 to 2,400 MPN g -1 (r s MPN cm -1 =-0.114; r s MPN g -1 = 0.211). Thirty isolations were obtained, most of which belonged to the species V. cholerae (n=11) and V. parahaemolyticus (n=7). Conclusions. The outcomes of the present study suggest that, even in the absence of symptoms of vibriosis, the microbiota of the hepatopancreas of cultured shrimp may include sucrose positive and negative vibrios.

In the aquatic environment, Vibrio cholerae has been reported to be associated with a variety of living organisms, including animals with an exoskeleton of chitin, aquatic plants, protozoa, bivalves, waterbirds, as well as abiotic substrates (e.g. sediments). Most of these are well-known or putative environmental reservoirs for the bacterium, defined as places where the pathogen lives over time, with the potential to be released and to cause human infection. Environmental reservoirs also serve as V. cholerae disseminators and vectors. They can be responsible for the start of an epidemic, may be critical to cholera endemicity, and affect the evolution of pathogen virulence. To date, in addition to the generally recognized role of zooplankton as the largest environmental reservoir for V. cholerae, other environmental reservoirs play some role in cholera epidemiology by favouring persistence of the pathogen during inter-epidemic periods. Little is known about the ecological factors affecting V. cholerae survival in association with aquatic substrates. Studies aimed at these aspects, i.e. understanding how environmental reservoirs interact, are affected by climate, and contribute to disease epidemiology, will be useful for understanding global implications of V. cholerae and the disease cholera.

“…Stauder et al described two V. cholerae colo nization factors promoting adhesion to chitin: mannose sensitive hemagglutinin (MSHA) and N acetylglu cosamine binding protein A (GbpA) [37]. Thus, seafood can be an important reservoir of pathogenic vibrios, and thus constitute a serious threat to human health [38,39] and risk of development of epidemics.…”

The role of chitin and its hydrolysis products generated by Vibrio cholerae chitinases in mechanisms of its adaptation in water environments, metabolism, preservation, acquisition of pathogenic potential, and its epidemiological value are reviewed. Chitin utilization by V. cholerae as a source of energy, carbon, and nitrogen is described. Chitin association promotes biofilm formation on natural chitinous surfaces, increasing V. cholerae resistance to adverse factors in ecological niches: the human body and water environments with its inhabitants. Hydrolytic enzymes regulated by the corresponding genes result in complete chitin biodegradation by a chitinolytic catabolic cascade. Consequences of V. cholerae cell and chitin interaction at different hierarchical levels include metabolic and physiological cell reactions such as chemotaxis, cell division, biofilm formation, induction of genetic competence, and commensalic and symbiotic mutual relations with higher organisms, nutrient cycle, pathogenicity for humans, and water organisms that is an example of successful interrelation of bacteria and substratum in the ecology of the microorganism.
