“…These factors would control the physico-chemical characteristics of each lake, and therefore their susceptibility to constitute habitats for Vibrio cholera [67]. Consequently, the bacillus niche does not appear to be significantly different from that described in previous studies in coastal areas [2,3,5,6,68], such as the lagoon areas of India [4].…”

Volcanic activity controls cholera outbreaks in the East African Rift

et al. 2020

We hypothesized that Cholera (Vibrio cholerae) that appeared along Lake Kivu in the African Rift in the seventies, might be controlled by volcano-tectonic activity, which, by increasing surface water and groundwater salinity and temperature, may partly rule the water characteristics of Lake Kivu and promote V. cholerae proliferation. Volcanic activity (assessed weekly by the SO 2 flux of Nyiragongo volcano plume over the 2007-2012 period) is highly positively correlated with the water conductivity, salinity and temperature of the Kivu lake. Over the 2007-2012 period, these three parameters were highly positively correlated with the temporal dynamics of cholera cases in the Katana health zone that border the lake. Meteorological variables (air temperature and rainfall), and the other water characteristics (namely pH and dissolved oxygen concentration in lake water) were unrelated to cholera dynamics over the same period. Over the 2016-2018 period, we sampled weekly lake water salinity and conductivity, and twice a month vibrio occurrence in lake water and fish. The abundance of V. cholerae in the lake was positively correlated with lake salinity, temperature, and the number of cholera cases in the population of the Katana health zone. V. cholerae abundance in fishes was positively correlated with V. cholerae abundance in lake water, suggesting that their consumption directly contaminate humans. The activity of the volcano, by controlling the physico-chemical characteristics of Lake Kivu, is therefore a major determinant of the presence of the bacillus in the lake. SO2 fluxes in the volcano plume can be used as a tool to predict epidemic risks.

“…Cholera is a severe infectious disease caused by Vibrio cholerae. This bacillus thrives in alkaline saline aquatic environments with high temperatures and rich in organic matter and plankton [1][2][3][4][5][6]. The bacillus is found in coastal areas, where fresh water from rivers mixes with salt water from the sea [1,2,[7][8][9][10].…”

“…Vibrios have been associated with climate change and have been proposed as bioindicators of climate change in marine systems [ 55 , 56 ], and since their abundance in the water is temperature related [ 57 ], they have rapidly adaptive behavior, more than one portal of entry, and have dominated the temperate climate zone, with outbreaks occurring ever closer to the poles. Thus, it can be speculated that the Mediterranean Sea in the near future will be an ideal setting for more Vibrio spp.…”

Pathogenic and Opportunistic Vibrio spp. Associated with Vibriosis Incidences in the Greek Aquaculture: The Role of Vibrio harveyi as the Principal Cause of Vibriosis

2023

A monitoring program to follow vibriosis incidents in the Greek marine aquaculture was implemented over the past 13 years. 273 isolates, from various cases originating from eight regions and nine hosts, were collected and characterized. The main aquaculture species of the survey were the European seabass (Dicentrarchus labrax) and the gilthead seabream (Sparus aurata). Various species of Vibrionaceae were associated with vibriosis. Vibrio harveyi had the highest prevalence and was isolated throughout the year from all hosts. During the warm months, Vibrio harveyi prevailed with frequent co-isolations of Photobacterium damselae subsp. damselae and Vibrio alginolyticus, while during spring, other Vibrio species were more abundant, such as Vibrio lentus, Vibrio cyclitrophicus, and Vibrio gigantis. Phylogenetic analysis using the mreB gene and the metabolic fingerprint of the isolates showed great variability within the species of the collection. The severity of the disease and the frequency of outbreaks make vibriosis (that is, mainly attributed to V. harveyi) an important concern for the regional aquaculture sector.

“…In recent years, some studies of model establishment and Vibrio prediction have been reported. Hidemasa Izumiya et al conducted a multi-coastal study to examine relationships between environmental factors and Vibrio and build a linear regression model for Vibrio prediction (Izumiya et al, 2017). Brett Froelich et al conducted a five-parameter mechanistic model to predict Vibrio abundance in the river based on environmental processes (Froelich et al, 2013).…”

“…in seawater can cause seafood-borne illnesses through consumption of contaminated seafood and cause wound infections by exposure of an open wound to seawater, probably resulting in diarrhea, septicemia and even death (Hsieh et al, 2008). The forecasting of Vibrio abundance and breakout would help to prevent human illness by identifying and reporting the forecasting information and making it publicly available (Froelich et al, 2013;Izumiya et al, 2017).…”

Bacteria in coastal waters drive global biogeochemical cycling and are strongly related to coastal environmental safety. The bacterial community in offshore shellfish farming waters of North China has its own characteristics and particularities, while the knowledge is limited. In this study, the bacterial community characteristics, the particularities of bacterial community in the waters with surface cold patches (SCPs) and the variation of pathogenic bacteria were investigated in the offshore shellfish farming waters in the North Yellow Sea (NYS) from 2017 to 2019. For all studied samples, Desulfobacterales acted as the keystone species taxon in microbial co-occurrence networks, and the proportional abundance of Actinobacteriota was found to be as low as 1.3%. The abundance of Marinobacter and Synechococcus was remarkably prominent in 13 genera with nitrogen-transforming function. The top two different bacterial functions in the spatial analysis (between the waters with SCPs and the ambient waters) were xenobiotics biodegradation and metabolism and metabolism of cofactors and vitamins, which were same with that in the seasonal analysis (between spring and summer). The abundance differences of most pathogenic bacteria analyzed in this study (11 out of 12 genera) also had the same variation dynamics between the spatial analysis and the seasonal analysis. An ANN predictive model for Vibrio abundance was constructed for Vibrio forecasting, with acceptable predictive accuracy. According to the above results, the bacterial community in the shellfish aquaculture waters in this study was characterized by the enhancing ability of nitrogen removal. Temperature was concluded as the predominant environmental factor to drive the variation of bacterial community function and pathogenic bacteria patterns in the offshore shellfish farming waters with SCPs. The results of this study will further our understanding of the bacterial community characteristics in offshore shellfish farming waters, and help for Vibrio forecasting and coastal environmental safety in aquaculture seawater.
