The isolation of Escherichia coli from food is a major concern. Pathogenic strains of these bacteria cause diseases which range from diarrhea to hemolytic-uremic syndrome. Therefore the virulence genes in E. coli isolates from the mussel ( Mytella guyanensis) commercialized in Cachoeira, Bahia, Brazil were investigated. Samples were purchased from four vendors: two from supermarkets and two from fair outlets. They were conditioned into isothermal boxes with reusable ice and transported to the laboratory for analysis. E. coli strains were isolated in eosin methylene blue agar, preserved in brain-heart infusion medium with 15% glycerol and stored at -20 °C, after microbiological analysis. Virulence genes in the isolated strains were identified by specific primers, with Polymerase Chain Reaction. Twenty-four isolates were obtained, with a prevalence of elt gene, typical from enterotoxigenic infection, in 75% of the isolates. The stx and bfpA genes, prevalent in enterohemorragic and enteropathogenic E. coli, respectively, were not detected. The occurrence of elt virulence-related gene in the E. coli isolates of Mytella guyanensis reveals urgent improvement in food processing, including good handling practices, adequate storage and cooking before consumption, to ensure consumer’s health.

“…A presença de esgotos domésticos também foi constatada pelos altos níveis de coliformes fecais na água da região da Bacia do Pina (FEITOSA, 1988). A presença de coliformes fecais e termotolerantes foi reportada em bivalves da espécie Anomalocardia brasiliana e em crustáceos Amphibalanusamphitritena coletados dentro do estuário (Barros et al 2009;Farrapeira et al 2010). Nas áreas urbanas, esse tipo de contaminação tende a gerar um grande risco à saúde humana, tais como cólera, febre tifoide e hepatite viral, devido ao aparecimento de microorganismos patogênicos, que podem ser ingeridos pelo homem através do consumo de peixes e frutos do mar contaminados, ou ainda pelo contato com a água (VON SPERLING, 1996).…”

O Sistema Estuarino do Rio Capibaribe (SERC) é um dos sistemas hídricos mais importantes do estado de Pernambuco, e é formado pelo estuário do rio Capibaribe, Bacia do Pina e Bacia Portuária. Infelizmente, a ação das atividades humanas em seu entorno associadas às elevadas cargas de contaminantes provenientes principalmente do lançamento de efluentes domésticos e industriais nos rios que o formam, têm resultado em um elevado nível de poluição ambiental. Com o intuito de avaliar as potenciais fontes de contaminação e grau de degradação deste sistema, foi feito um levantamento das indústrias instaladas nas proximidades do SERC e dos estudos realizados nesta região. Além disto, in situ, foram quantificadas as galerias de águas pluviais ou de lançamento de esgotos localizadas no trecho que compreende o Parque da Jaqueira até a confluência do rio Capibaribe com a Bacia do Pina. Os resultados reportados na literatura indicaram que a qualidade da água deste sistema está altamente comprometida, indicada através dos parâmetros Oxigênio Dissolvido, Demanda Bioquímica de Oxigênio, nutrientes, coliformes termotolerantes, metais, dentre outros, que estiveram em desacordo com os limites estabelecidos pela resolução CONAMA 357/05. Cerca de 57 indústrias de alto e médio potencial de poluição estão localizadas nas imediações do estuário. A presença de 150 pontos de lançamento de águas residuárias foram observadas no trecho estudado. O mau cheiro, lixo e a degradação visual, indicam a possibilidade de lançamentos de esgotos interligados nas saídas de águas pluviais, comprometendo cada vez mais a qualidade das águas, sedimentos e organismos do SERC. Estes resultados são bastante preocupantes, uma vez que essa região é muito importante do ponto de vista econômico, ecológico e social, sendo urgente a tomada de decisões que recuperem e priorizem a conservação desta área.

“…We compared the abundance of CB in Jiaozhou Bay with other areas worldwide (Supplementary Table 6). Farrapeira et al (2010) found that, based on MPN analysis, total coliforms in an estuary area in Brazil were more than 2.4 × 10 3 MPN/100 ml, while the abundance was 0.9 × 10 MPN/100 ml at a port station in May, 2007. Also in Brazil, Mignani et al (2013 reported that in 2007-2008, the mean abundance of CB in a cultivation area and a contaminated area was 18 and 156 MPN/100 ml, respectively.…”

“…Furthermore, bacteria can travel and be transported some distance (Jeng et al, 2005), which could be another reason for the phenomena in the estuary and inner bay areas. In the bay mouth and outer bay areas, the exchange of seawater between Jiaozhou Bay and the open sea is greater, so pollutions may be diluted to very low concentrations, and have less influence on CB abundances as highlighted in the research of Farrapeira et al (2010). Seawater could purify itself may be another possible explanation for the spatial distribution of CB in Jiaozhou Bay.…”

Long-Term Temporal and Spatial Distribution of Coliform Bacteria in Jiaozhou Bay Associated With Human Activities and Environmental Governance

Coliform bacteria (CB) can be used as an indicator of seawater quality. Long-term monitoring of seawater quality based on CB abundance is lacking in Jiaozhou Bay. In this study, CB abundance in surface seawater of 12 different stations in Jiaozhou Bay was investigated by culturing method. The results showed that: (1) the abundance of CB showed a decreasing tendency during the investigation. During 2004–2007, 2008–2013, and 2014–2017, the average CB abundance decreased significantly, forming a “three stages phenomenon”; (2) the average CB abundance in the first half of the year was lower than that in the second half; (3) the CB abundance in Jiaozhou Bay was spatially heterogeneous. The maximum average CB abundance was observed in the estuary area, and followed by the bay mouth area, the outer bay area, and the inner bay area. The highest abundance may be associated with sewage discharge related to human activities; (4) the abundance of CB was most positively correlated with the concentration of ammonium salt and nitrate, while most negatively correlated with salinity; (5) the years 2007 (2008) and 2013 (2014) were time points of the “three stages phenomenon.” These time points coincide with environmental governance actions, indicating that the actions have played a prominent role in improving seawater quality. Long-term survey of CB can not only serve as an indicator of seawater quality, but also provide a basis for the development of environmental governance strategies and pollution control.
