“…Gastroenteritis, vomiting and watery diarrhoea are common symptoms of V. parahaemolyticus infections (Daniels et al 2000;Oliver and Kaper 2007;Scallan et al 2011). However, in extreme cases, the infection can cause septicaemia in individuals with underlying chronic illness (Wright et al 1996;Oliver and Kaper 2007;Scallan et al 2011;Parveen and Tamplin 2013). All V. parahaemolyticus strains have a species-specific marker known as the thermolabile haemolysin gene (tlh + ).…”

“…Although V. vulnificus infections are rare, they have highest hospitalization (91Á3%) and mortality (34Á4%) rates of all foodborne pathogens in the United States (Scallan et al 2011). The three clinical conditions associated with V. vulnificus infection are wound infections, primary septicaemia and gastroenteritis (Parveen and Tamplin 2013). Primary septicaemia, the result of extreme cases of gastroenteritis or wound infection, is the most fatal condition (Shapiro et al 1998;Bross et al 2007;Oliver and Kaper 2007;Scallan et al 2011).…”

Aims: To determine the prevalence of total and pathogenic Vibrio parahaemolyticus (Vp) and V. vulnificus (Vv) in blue crabs, water and sediment from the Maryland Coastal Bays (MCBs), USA. Methods and Results: Crab, haemolymph, sediment and seawater samples were collected monthly from four sites in MCBs from February 2012 through October 2012 with environmental parameters recorded. The most-probablenumber (MPN) methodology was used to enumerate Vp and Vv with presumptive colonies and the presence of virulence markers confirmed using polymerase chain reaction (PCR). Results indicate that blue crabs contained both Vp and Vv at densities (7Á28 and 5Á43 log MPN g À1 , respectively) higher than those reported for bivalves. In addition, markers for clinically relevant strains of both species were detected in over 30% of samples. Haemolymph, sediment and seawater samples were also routinely positive for both species and clinically relevant strains, but generally at lower densities than found in crabs (4Á27, 3Á28, and 2Á39 log MPN g À1 per ml À1 Vp, and 4Á28, 2Á49 and 2Á38 log MPN g À1 per ml À1 Vv). Conclusions: Blue crabs concentrate Vp and Vv at levels greater than found in water or sediment. While changes in abundance associated with temperature are apparent, there is little evidence to support differences among sampling locations. Significance and Impact of the Study: These results highlight the potential for blue crab related vibriosis and the importance of proper handling, cooking and care of this popular seafood before consumption. IntroductionBlue crabs (Callinectes sapidus) exist along the western border of the Atlantic Ocean from the Canadian province, Nova Scotia down to Argentina (Reichmuth et al. 2009). They are of ecological and economic importance and require an estuarine environment such as the Chesapeake Bay and the Maryland Coastal Bays (MCBs) for growth.Ecologically, blue crabs perform many roles in the estuarine food web depending upon life stage (Reichmuth et al. 2009). Blue crabs are also a very popular delicacy in the US Gulf of Mexico and Atlantic coastal areas. In 2011, the Chesapeake Bay crab fishery had a total harvest of 67Á3 million pounds. According to the 2012 annual winter dredge survey completed by the Maryland Department of Natural Resources, the blue crab population had increased 66% to 764 million. This

“…, ), occurring when the frequency of cases of a disease is above what was expected in a defined community, geographical area or season (WHO, 2015). These outbreak strains can be identified by serotyping of the capsular (K) and lipopolysaccharide (O) antigens (Parveen and Tamplin ). Two serotypes are of particular importance, O4:K12 and O3:K6 and have been implicated in recent outbreaks and have worldwide presence.…”

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

et al. 2016

View full text Add to dashboard Cite

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.

Recently, medical plants have been widely used as replacements for antibiotics in disease treatment. Because of its multiple medicinal uses, peppermint (Mentha piperita, MP) is a common herbal remedy. In the present study, MP powder was used as a feed additive to assess growth performance; hematological; biochemical and immune parameters; intestinal histology; and interleukin 1β (IL-1β) gene expression, as well as protection against Vibrio alginolyticus infection in Oreochromis niloticus. O. niloticus (n = 120, 25.66 ± 0.16 g) were fed diets containing 0 (CTR), 2, 3, or 4% MP for 60 days. The results revealed that the inclusion of 2% MP significantly improved the growth indices, intestinal morphological parameters, and reduced the feed conversion ratio. The 2% MP treatment significantly (P < 0.05) increased hematological parameters (red blood cell (RBC) count, white blood cell (WBC) count, packed cell volume% (PCV%), hemoglobin) compared with those of the CTR (P < 0.05). Additionally, feeding fish 2% MP diets decreased the levels of cholesterol and LDL (low-density lipoprotein). There were significant increases in immune responses (serum protein and phagocytic activity and index) and non-significant increases in the expression of IL-1β in the 2% MP group comparing with the other groups and the CTR group (P < 0.05). At the end of the feeding trial (60 days), fish were challenged with a virulent strain of Vibrio alginolyticus and the results showed that the mortality rate decreased in the 2% MP treatment group, followed by the 3% and 4% MP groups. Overall, the results revealed that the dietary inclusion of 2% MP can exhibit growth-promoting and immunostimulant effects for sustainable aquaculture.
