“…Many studies show the presence of Vibrio in aquatic animals such as fish [ 40 ], shrimp [ 41 ], and mussels [ 42 ], but, despite the importance of crabs, only some studies have been conducted on crab contamination by Vibrio . However, its occurrence in marine food is pointed as a major cause of gastroenteritis in the United States and Europe [ 43 ] and associated with cases in Brazil and Chile [ 44 ]. These results suggest a probable health risk for people that consume raw and undercooked seafood.…”

The bacteriological quality of crabs from three different mangroves (Itaóca, Suruí, and Piedade) from Rio de Janeiro state, Brazil, was investigated using conventional and molecular methods. The results revealed high counts for total coliforms in meat and hepatopancreas samples. PCR analyses identified 25 Escherichia coli colonies in the Itaóca, Piedade, and Suruí samples, detecting 13 enterotoxigenic colonies and 9 enteroaggregative colonies. Respectively, 12, 11, and 21 Vibrio parahaemolyticus strains were detected in the Itaóca, Piedade, and Suruí samples. Two V. cholerae strains were detected in the Piedade samples. The E. coli strains isolated in the present study showed resistance to gentamicin. E. coli strains from the Piedade samples showed 33% resistance to chloramphenicol and the strains also showed multiresistance to several antimicrobial agents with a MAR index ranging from 0.12 to 0.31. Vibrio strains from Piedade, Itaóca, and Suruí showed 86%, 78%, and 85% resistance, respectively, to ampicillin. The isolated Vibrio strains showed multiresistance to several antimicrobial agents, with a MAR index ranging from 0.12 to 0.25. The presence of these organisms in crab meat is an indication of microbial contamination, which may pose health risks to consumers when improperly cooked.

“…These establishments, which stock native and exotic fish species in lakes or ponds and offer pay‐fishing as the main attraction, are regulated by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) and inspected by the National Health Surveillance Agency (ANVISA). This inspection is important because, although fish are a healthy source of protein, they can also spread diseases caused by pathogenic micro‐organisms they may contain (Santos and Vieira ).…”

Pay-to-fish ponds are a common commercial activity in Brazil. Samples of water and Oreochromis niloticus were examined by PCR to detect the presence of pathogenic strains of Escherichia coli (O157, enteropathogenic and shiga toxigenic). Several pathogenic strains were detected in this study, providing useful epidemiological information for the proper management of these environments and animals in order to prevent faecal pollution, reducing health risks to the Brazilian population.

“…The strain was serotyped as O5:K17, Kanagawa‐positive. There are no epidemiological data available, except that the local population was known to eat salt‐cured marine and freshwater fish (Hofer ; dos Santos and Vieira ). Even though there are other V. parahaemolyticus serotypes such as the above mentioned O5:K17 in South America, O3:K6 and O4:K12 serotypes are worth mentioning as they are related to outbreaks in South America and also in other continents as cited previously (Bhuiyan et al .…”

Vibrio parahaemolyticusandVibrio vulnificusin South America: water, seafood and human infections

et al. 2016

The bacterial species, Vibrio parahaemolyticus and Vibrio vulnificus, are ubiquitous in estuaries and coastal waters throughout the world, but they also happen to be important human pathogens. They are concentrated by filter-feeding shellfish which are often consumed raw or undercooked, providing an important potential route of entry for an infective dose of these bacteria. Vibrio parahaemolyticus can cause abdominal cramping, nausea, diarrhoea, vomiting, chills and fever. Vibrio vulnificus can cause similar gastrointestinal-related symptoms, but can also spread to the bloodstream, resulting in primary septicaemia, and it can also cause disease via wound infections. The objective of this article is to summarize, for the first time, the incidence and importance of V. parahaemolyticus and V. vulnificus in South America, in environmental waters and seafood, especifically molluscan shellfish, as well as human infection cases and outbreaks. It appears that infections from V. parahaemolyticus have been more strongly related to shellfish ingestion and have been more frequently reported on the Pacific coast of South America. Conversely, V. vulnificus has been more frequently acquired by water contact with open wounds and its presence has been more heavily reported along the Atlantic coast of South America, and while documented to cause serious mortality, have been relatively few in number. The impacts of El Nino Southern Oscillation (ENSO) have been observed to cause an increase in V. parahaemolyticus outbreaks on the Pacific coast of South America. The implementation of a regulated monitoring approach, along with the use of faster, more accurate and virulence-specific detection approaches, such as PCR confirmation, should be considered to detect the presence of pathogenic Vibrio strains in environmental and seafood samples for protection of public health. Furthermore, improved clinical surveillance with suspected cases should be implemented. This review highlights the need for more research and monitoring of vibrios in South America, in water, shellfish and clinical samples.
