“…Previous studies have reported the emergence of antibiotic resistance in STEC, particularly to trimethoprim/sulfamethoxazole, b-lactams (Zhao et al, 2001), being in agreement with the resistance profile exhibited by isolate 57. In addition to this, previous reports have highlighted the presence of antibiotic resistance in other bacteria present in this geographical location (Garrido-Maestu et al, 2016;Lozano-Le on et al, 2003).…”

“…The risk to public health associated with the consumption of shellfish, traditionally consumed raw or undercooked, has been well documented previously (Feldhusen, ; Potasman, Paz, & Odeh, ). In this sense, pathogenic Vibrio species were detected and yet implicated in shellfish foodborne diseases in Galician Rias (Lozano‐León, Torres, Osorio, & Martínez‐Urtaza, ; Martinez‐Urtaza et al, ; Rodriguez‐Castro & Martinez‐Urtaza, ), furthermore the presence of antibiotic resistance genes has also been reported (Garrido‐Maestu et al, ).…”

Shiga toxin‐producing Escherichia coli are a known cause of serious illnesses, and a major public health concern. The coastal environment is the receptacle of agricultural and urban wastewater effluents, thus STEC can be present. In the current study their occurrence and prevalence in mussels (Mytilus galloprovincialis) cultured in the southern Rias of Galician was assessed. This region is interesting due to its economic importance as Galicia produces the 98% of the mussels cultured in Spain, being this country the third world producer. From June 2012 until September 2013, 241 mussel samples were collected, being 112 positive for eae and 17 also positive for stx1,2. An increase was observed in the winter months for both genes, which seemed correlated with a generalized decrease in water salinity. Serotype O157:H7 was not detected, but one isolate resulted resistant to six antibiotics, denoting the presence of multidrug resistant bacteria in this área. Practical applications A critical step for adequate risk assessments is the evaluation of potential threats. In this sense, very few microbiological parameters are analyzed in bivalve molluscs, being many human pathogens not assayed. Shiga toxin‐producing Escherichia coli was detected for the first time in mussels harvested in Galicia, a region of critical importance worldwide for the mussel industry. This study highlights that additional studies to better characterize the microbial populations of this important region are still needed, and furthermore, that measures to control microbial pathogens, such as depuration, must not be taken lightly.

“…This is because seafood can be a vehicle for pathogens. Vibrio sp., which is one of the genera from Bacteria kingdom [12] , has been associated with gastroenteritis and wound infections in human [13] , such as V. vulnificus [14] , V. parahaemolyticus [15] and V. cholerae [16] . Foodborne Diseases Active Surveillance Network (Food-Net) reported that in the year 2018, Vibrio sp.…”

Vibrio sp. has been a major pathogen that resulted in difficult to treat infections, and greatly impacting the aquaculture industry. Thus, more effective approaches are needed to overcome this problem. Bacteria of the genus Streptomyces is a group of prolific producers for various bioactive compounds. Streptomyces species with antibacterial activity against Vibrio sp. have been reported from numerous studies, indicating that Streptomyces could be a good candidate for treatment of Vibrio infections. This review aims to provide an overview on the distribution of the Streptomyces with anti-Vibrio activity from diverse geographical locations. Furthermore, this review also highlighted that Streptomyces sp. can be a great source for anti-Vibrio agents to control vibriosis, such as in the aquaculture settings.

“…Studies on the isolation of these pathogenic vibrios from molluscs and crustaceans have been reported from different geographical locations of the world. These reports include those from Korea, Spain, Poland, Morroco, Egypt ( 4 – 8 ). The various studies mentioned earlier have been able to prove that aquatic animals have the ability to harbor pathogenic Vibrio species but none have been able to experimentally proven if these seafood are just transient or concentrating carriers.…”

Limpet (Scutellastra cochlear) serves as seafood recipe and an important member of the aquatic food chain. It is an abundant mollusc in some aquatic environment in South Africa. In this study, we investigated the potential of the molluscs harvested from the Buffalo, Swartkops, and Kowie estuaries in the Eastern Cape Province, South Africa to serve as transient or maintenance reservoir of Vibrio species. The mollusc and source water samples were collected monthly from the rivers between December 2016 and November 2017. The reservoir category of the limpet samples recovered was determined by employing the combination of MPN-PCR method and statistical analysis (comparison of mean and proportion tests). The densities of Vibrio spp. in limpet and their source water samples were determined using MPN-PCR methods. Presumptive isolates were recovered by processing the samples with thiosulfate-citrate-bile salts-sucrose agar and where necessary, samples were enriched with alkaline peptone water. The presumptive isolates were identified using PCR methods with emphasis on six Vibrio species of public health importance. Vibrio spp. were detected in all the limpet samples but not in all the water samples. The densities of Vibrio spp. in the limpet samples were more than the densities of Vibrio species in their source water and these were significant at P < 0.05. In like manner, five out of the six key Vibrio pathogens targeted in this study were more prevalent in limpet samples than in source water samples. Based on our findings, we concluded that our method though could be improved on, is efficient for the determination of reservoir types of bacterial-carrying organisms. We also concluded that the limpet found in the estuaries are not just a transient but a maintenance reservoir of Vibrio spp. which could cause vibrio-related infections.
