“…Espécies do gênero Vibrio são conhecidas por infectar animais marinhos e estuarinos, além de causar doenças em humanos em caso de ingestão de animais contaminados e contato de mucosas ou ferimentos com água e sedimentos contaminados (SILVEIRA et al, 2016). Nesse sentido, a densidade de células de Vibrio na margem urbanizada do rio merece atenção, visto que pode servir como ponto de contaminação para animais e pessoas que habitam o local.…”

O estuário do rio Coreaú possui uma das margens tangenciando a área urbana de Camocim, enquanto a outra tangencia a APA das Dunas da Ilha da Testa Branca. Com o objetivo de verificar os efeitos das atividades antrópicas na margem urbanizada, este trabalho analisou parâmetros físico-químicos e microbiológicos em ambas as margens. Análises de pH, temperatura, turbidez, oxigênio dissolvido e DBO5 foram realizadas na água. Amostras do sedimento foram utilizadas para quantificação de matéria orgânica e de bactérias heterotróficas, enumeração de coliformes, quantificação de células procarióticas e de bactérias patogênicas. Não houve diferença significativa para os parâmetros físico-químicos, exceto para matéria orgânica no sedimento, maior na margem urbanizada. A densidade de bactérias heterotróficas e de células procarióticas é maior na margem urbanizada. Os resultados indicaram que coliformes termotolerantes ocorrem apenas na margem urbanizada. Todos os taxa bacterianos patogênicos são encontrados em maior densidade na margem urbanizada, onde a densidade de E. coli é quase cinco vezes maior. Nossos resultados indicam que o descarte de águas residuárias está relacionado com a maior densidade de bactérias patogênicas no sedimento da margem urbanizada o que pode resultar em um problema de saúde pública.

“…The occurrence of Vibrio species (V. alginolyticus, V. fluvialis, V. metschnikovii, and V. parahaemolyticus) can be explained by the fact that these microorganisms are considered autochthonous (native) from marine and estuary environments, which inhabit these places due to availability of sodium chloride (NaCl), salt necessary for its growth (Silveira et al 2016). Reis et al (2010) detected a positive result of 88.2% for Vibrio in the oral, nasal, and cloacal mucosa, and wounds of free-living juvenile C. mydas.…”

Isolation and characterization of the aerobic bacterial microbiota of the esophagus and its probable association with obstructive caseous lesions in green turtles (Chelonia mydas)

Caseous lesions in the esophagus of green turtles (Chelonia mydas) from the coast of Brazil have been described as obstructive lesions and can lead to the death of these animals. However, their etiology remains unclear. The aim of this study was to isolate and characterize the aerobic bacterial microbiota of the esophagus of green turtles (C. mydas) from the Brazilian coast and to verify its possible participation in the etiology of caseous lesions. For this, 42 animals were used, 33 alive and healthy and 9 naturally dead that had esophageal lesions confirmed by necropsy, from Anchieta and Piúma beaches, Espírito Santo. Microbiological tests and morphological evaluation of the esophagus were performed. We isolated 14 different bacterial agents from healthy animal samples, with the prevalence of Pseudomonas aeruginosa being (36.36%), Staphylococcus aureus (33.33%), Aeromonas hydrophila (27.27%), and Vibrio alginolyticus (24.24%). In dead animals, only three distinct agents were isolated: S. aureus (50.00%), A. hydrophila (25.00%), and V. alginolyticus (25.00%). Morphological evaluation revealed a predominance of the lesions at the gastroesophageal junction, with multifocal-to-coalescent distribution, discrete intensity, and absence of obstruction. Ulcerations and caseous exudates, inflammatory infiltrates, parasitic eggs, and giant foreign body cells were also observed as well as bacterial lumps and glandular alterations, such as necrosis, adenitis, and fragments of adult parasites. There was a positive correlation between bacterial lumps and microbiological culture and a negative correlation between bacterial lumps and microbiological culture with parasites. Thus, it was noted that the esophageal aerobic microbiota of C. mydas was predominantly composed of Gram-negative bacteria such as P. aeruginosa, A. hydrophila, and V. alginolyticus, in addition to several enterobacteria and Gram-positive bacteria, such as S. aureus. These agents are opportunists and may be involved in the etiology of caseous esophagitis in association with other pathogens as co-factors working in association or, even in a secondary way.

“…Table 3: Different biochemical characteristics of Vibrio vulnificus biotypes have been identified (Colodner et al, 2004;Oliver, 2005;Silveira et al, 2016) Vibrio vulnificus ------------------------------------------------------------------------------------------------------------ However, due to the composition of fish, they are also highly susceptible food to deterioration and contamination (physical, chemical, or biological) due to their pH being close to neutral, high-water activity, nutrient content, microbial activity, autolysis, and oxidation (Centeno and Rodriguez, 2005;Soares and Goncalves, 2012;Fuertes et al, 2014;Rabiela, 2015;Silva et al, 2017). It should be noted that the freshness, nutritional quality, and safety of fish depend on factors such as species, age, habitat, diet, catch conditions, harvest, processing, conservation, transport, distribution, and commercialization (Huss, 1998;Centeno and Rodriguez, 2005;Soares and Goncalves, 2012;Fuertes et al, 2014;Rabiela, 2015;Silva et al, 2017).…”

“…Species such as V. cholerae, V. parahaemolyticus, V. vulnificus, V. mimicus, V. alginolyticus, V. fluvialis, V. furnissii, V. metschnikovii, and V. hollisae are considered human pathogens (Ramamurthy et al, 2014;Cortés-Sánchez et al, 2016;Silveira et al, 2016;Kaysner et al, 2019;Brumfield et al, 2021). Similarly, species of the genus Vibrio can be pathogens of freshwater and saltwater fish and are responsible for outbreaks of diseases in animals called epizootics (Mustapha et al, 2013;Rehulka et al, 2015).…”

“…V. vulnificus has been classified based on biotypes, Lipopolysaccharide (LPS) antigens, capsules, and genetic sequences (Gulig et al, 2005;Oliver, 2005;Horseman and Surani, 2011;Silveira et al, 2016). Three biotypes of V. vulnificus have been reported and they are identified by different biochemical characteristics, such as indole and ornithine decarboxylation and growth at 42°C (Table 3) (Colodner et al, 2004;Oliver, 2005;Fouz et al, 2010;Horseman and Surani, 2011;Silveira et al, 2016;Cho et al, 2018).…”

Foodborne Diseases (FD) constitute a major global public health challenge due to their incidence and related mortality. Bacteria are frequently related to the generation of FD outbreaks. Fish is a highly nutritious food that is marketed and consumed globally. However, they are also susceptible to deterioration and contamination due to biological hazards related to unsanitary conditions and practices occurring throughout the food chain. Vibrio vulnificus is considered a human pathogen related to diseases and is transmitted by manipulation and consumption of aquatic foods, mainly in the raw state. This microorganism is also a fish pathogen that generates epizootics in culture with consequent economic losses and risks to human health due to transfer in the food chain. Aquaculture is a source of food such as fish that has grown over the years, becoming an important form of subsistence worldwide. Tilapia is an aquaculture species that, depending on culture conditions, may be at risk of V. vulnificus infections that would generate negative effects on animal health and compromise food safety. Therefore, the purpose of this document is to provide a general perspective on diseases transmitted by the food of aquatic origin derived from the handling and consumption of fish, specifically tilapia and whose causal agent is V. vulnificus. The metabolic, ecological, isolation, and identification characteristics of this pathogen are pointed out, in addition to the various actions to control and prevent negative impacts on public health due to this biological hazard in foods of aquatic origin.
