“…Numerous studies have established that the salinity/temperature binomial is important for the dynamics of Vibrio spp [18], [20], [54], [21], [47]- [53] and they are known to be the strongest abiotic correlates among those investigated [5]. In our study area, salinity is high, corresponding to metahaline waters with a median of 39.5 ppt, and very little variation (CV: 0.039), because estuaries were not included.…”

Vibrionaceae include several human pathogens such as Vibrio cholerae, Vibrio vulnificus or Vibrio parahaemolyticus. The risk of vibriosis is increasing worldwide due to the effects of climate change and modified patterns of food consumption, leading to a considerable economic and public health interest in understanding the factors related to the greater abundance of vibrios. Fluctuations in Vibrio populations are strongly affected by changes in temperature and salinity, nonetheless, there is substantial variability in their effect and discrepancies in their specific roles. In this study, we analyzed the abundance, and spatiotemporal distribution of Vibrio in the Euro-African Atlantic area, focusing the investigation on associations with environmental factors and with an emphasis on V. parahaemolyticus. Using membrane-filtration, cultures and MALDI-TOF mass spectrometry, 191 samples from 12 locations were analysed and a biochemical and proteomic profile created. We developed two multivariate linear regression models for the density of Vibrio spp (adjusted R2 = 0.32 and 0.27) and a logistic regression model for the occurrence of V. parahaemolyticus (R2Nagelkerke = 0.32, Accuracy = 77%). Including the interaction between sea surface temperature (SST) and salinity in linear regression helps to explain the discrepancies found in several studies on the effect of these variables on the abundance of vibrios.

“…Vibrio cholerae widely exists in all types of waterbodies [ 19 , 20 ] and it has been reported that V. cholerae can infect aquatic animals including fish [ 21 , 22 ], shrimps [ 23 , 24 ] and other aquaculture animals [ 25 , 26 ]. The cause of cholera epidemics is extraordinarily complex, and it is unclear how it spreads, while the reason for seasonal epidemic peaks in epidemic areas are also unknown.…”

Bullfrog is one of the most important economic aquatic animals in China that is widely cultured in southern China and is a key breed recommended as an industry of poverty alleviation in China. During recent years, a fatal bacterial disease has often been found in cultured bullfrogs.The clinical manifestations of the diseased bullfrogs were severe intestinal inflammation and an anal prolapse. A bacterial pathogen was isolated from the diseased bullfrog intestines. The bacterium was identified as Vibrio cholerae using morphological, biochemical and 16S rRNA phylogenetic analysis. In this study, V. cholerae was isolated and identified in diseased bullfrogs for the first time, providing a basis for the diagnosis and control of the disease. Therefore, .

“…Although V. mimicus to a certain extent has been shown to have some similarity to V. cholerae [25], there have only been a global record of high morbidity and mortality due to infections with Vibrio parahaemolyticus and Vibrio vulnificus [26]. However, V. cholerae O1 and V. parahaemolyticus serotype O3:K6 have been noted for their formidable pathogenicity and significant ability to cause bacterial pandemics [27][28][29]. Vibrio vulnificus also has been incriminated in wound infections, while epidemic cholera is associated with V. cholerae [19].…”

In the coastal areas of the world, most Vibrio species have been incriminated as notorious agents causing foodborne, wound and other infections. These pathogens are known to be associated with the consumption of raw or undercooked seafoods or the exposure of wounds to warm seawater. Aim: Therefore, this research work was designed with the aim of assessing the microbiological quality of the water bodies as well as the seafoods consumed in Cross River State (CRS). Study Design: The Study was designed using the completely randomized block design and the data was analyzed using of two-way analysis of variance, Generalized Linear Model Univariate analysis. Significant means were separated using the Least significant difference (LSD). Place and Duration of Study: This study was done in the Department of Microbiology, University of CRS, Calabar, CRS, Nigeria, between 2016-2019. Methodology: we evaluated a variety of seafoods viz; crayfish, blue crabs, Periwinkles, apple nails, red lobsters etc. collected from major Beaches, markets and other sale points and water sources (rivers streams sea and gutters) in Calabar, CRS of Nigeria, using standard bacteriological techniques, for the prevalence of Vibrio species. Results: The mean percentage mean viable cell counts obtained ranged from 1.79±3.45 (seawater)-9.15±4.79CFU/mL (gutter water) and 7.68±7.58 (Blue Crab)- 11.37±4.82 CFU/g (fish) in the Rainy season. The counts for the Dry season Ranged from 1.79 ±3.42 (Seawater)-8.94± 4.51(gutter water), and 5.83 7.21 CFU/g (apple snail) -12.64 5.95 CFU/g (Fish). The total percentage mean counts obtained were 8.09±6.91 CFU/mL in the Rainy Season to 7.61±6.58 CFU/mL in the dry Season. From both seasons, the overall total mean count was 11.09±5.94 CFU/ml. From the nine locations evaluated in this study, it was observed that the Mean percentage counts for the Northern Senatorial District (NSD) ranged from 2.81± 3.49 (Ogoja)- 3.14 ±4.07CFU/mL (Obudu). For the Central (CSD) the range was from 3.34 ±4.20 (Boki)- 9.89 ±5.15 (Ikom), while for the Southern (SSD) it was from12.01± 6.52 (Akamkpa)- 14.47 ±5.44 (Calabar). The overall Total percentage mean counts from all the three Senatorial Districts was 14.03±4.86 CFU/mL. From the Northern Senatorial District, the total Percentage mean was 3.01±3.77 CFU/mL, 7.05±5.79 CFU/mL from the Central and 13.49± 5.72 CFU/mL from the Southern Senatorial District. The Vibrio pathotypes isolated include Vibrio cholerae (V. cholerae) (both O1 and non-O1 serotypes) 1155 (31.61%), Vibrio parahaemolyticus (V. parahaemolyticus), 752 (20.58%), Vibrio fluvialis (V. fluvialis) 480 (13.14%), V. vulnificus 473 (12.94%) Vibrio mimicus (V. mimicus) 400 (10.95%) and Other Vibrios 394 (10.78%). Out of the 3654 Vibrio isolates, the greatest number 663±3.31 (18.14%) were from Seawater, while the least 133±.84 (3.64%) were from the Gutter Water. Also, the highest number 1245±2.61 (34.07%) came from Calabar, and the least 102±.65 (2.79%) from Obanlikwu. The NSD had the least number 327 (8.95%), followed by the CSD with 570 (15.59%) and then the SSD with 2757 (75.45%) as the highest number of isolates. Conclusion: The presence of these pathogenic bacterial species in common seafoods in this area is of great public health concern. It is therefore important that serious emphasis be laid on proper cooking of these seafoods as well as the establishment of regular hygiene surveillance strategies in the state.
