“…O sorotipo O1:K25 também apresenta relevância, pois tem sido reconhecido por causar surtos de gastrenterite associado ao consumo de alimentos marinhos e considerado um sorotipo fortemente associado ao clone O3:K6 4 5 14 . Os sorotipos mais comumente identificados no Brasil nas duas últimas décadas foram O2:K28, O3:K5, O10:K52, O5:K17 e O4:K12 10 . O primeiro relato de identificação do sorotipo O3:K6 em nosso meio ocorreu em 1997 16 , isolada de pescado, contudo, desde este período não há nenhum registro desse sorotipo envolvido em surto humano no Brasil.…”

“…Em nosso meio, diversos estudos revelaram a incidência de V. parahaemolyticus no ambiente aquático, particularmente salino e também a partir de alimentos de origem marinha. Nestes, é confirmada a assertiva quanto à freqüência de isolamento desse microrganismo, mais elevada nos meses de verão, tanto nas zonas temperadas como nas tropicais, sugerindo uma característica de sazonalidade 10 .…”

O ecossistema marinho é o habitat natural de bactérias como Vibrio parahaemolyticus, um importante patógeno causador de gastrenterite humana associada ao consumo de alimentos marinhos. Na presente investigação, foi avaliada a presença de V. parahaemolyticus a partir de 86 amostras de mexilhões in natura e pré-cozidos. Vibrio parahaemolyticus foi isolado a partir de 11,6% dos mexilhões in natura e pré-cozidos avaliados. Todas as cepas avaliadas demonstraram-se urease positivas e 28,5% Kanagawa positivas sugerindo um potencial patogênico para o homem. Houve a predominância do sorotipo O10:K52 e a identificação da cepa emergente O3:K6. Esses resultados apontam para a relevância epidemiológica de V. parahaemolyticus em casos de gastrenterite humana após consumo de mexilhões sem cozimento adequado (100ºC/15min). Além disso, é importante alertar as autoridades de Vigilância Sanitária no Brasil quanto a sua presença na cadeia alimentar e seus riscos para a Saúde Pública.

“…In relation to Brazil, there are few references to V. parahaemolyticus in cases of intestinal infections of human isolates (Hofer, 1983; Magalhaes et al, 1991a,b, 1992) in the colonization of cutaneous wounds (Rodrigues et al, 2001). In 1991 in Recife, a tropical city situated in Northeast Brazil, V. parahaemolyticus cultures were isolated from 21 cases of gastroenteritis associated with the consumption of different types of seafood.…”

Vibrio parahaemolyticus is one of the most important seafood-borne bacterial in recent years and is the leading causal agent of human acute gastroenteritis, primarily following the consumption of raw, undercooked or mishandled marine products. Until 1996, infections caused by V. parahaemolyticus were generally associated with diverse serovars. However, in February 1996, a unique serovar (O3:K6) of V. parahaemolyticus with specific genetic markers (tdh, toxRS/New and/or orf8) appeared abruptly in Kolkata, India. In subsequent years, O3:K6 isolates similar to those isolated in Kolkata have been reported from food borne outbreaks in Southeast Asia, as well as in the Atlantic and Gulf coasts of the United States (U.S). More recently, there have been reports in Europe, Africa and Central and South America. Specifically, in the American continent, some countries have reported cases of gastroenteritis due to the pandemic O3:K6 strain and its serovariants; the pandemic strain was first detected in Peru (1996, >100 cases), subsequently spreading to Chile in 1998 (>16,804 human cases), to the U.S. in 1998 (>700 cases), to Brazil in 2001 (>18 cases) and to Mexico in 2004 (>1200 cases). The arrival of the pandemic clone on the American continent may have resulted in a significant shift on the epidemic dynamics of V. parahaemolyticus. However, although O3:K6 is the predominant serovar of the recognized clinical strains in some countries in the Americas, a decrease in clinical cases caused by O3:K6 and an increase in cases associated with a new serotype (O3:K59, Chile) have been recently reported. The emergence and worldwide dissemination of O3:K6 and other pandemic strains since 1996 have come to represent a threat to public health and should concern health authorities. This review focuses on the presence, distribution and virulence factors of the V. parahaemolyticus O3:K6 pandemic clone and its serovariants in clinical and environmental strains on the American continent.

“…MAGALHÃES et al 60,62 analyzed 1,100 diarrheal fecal samples from Recife, Pernambuco State, 14 (1.3%) of which were contaminated with V. parahaemolyticus. The contaminated individuals presented symptoms of gastroenteritis (cramping abdominal pain, nausea, vomiting, fever, chills and headache).…”
