“…I en nylig avsluttet studie fra Havforskningsinstituttet og Universitetet i Bergen, ble det undersøkt for Vibrio-bakterier Det er lite data tilgjengelig om forekomsten Vibrio-bakterier i det norske marine miljøet, men tidligere studier har vist at V. cholerae, V. vulnificus og V. parahaemolyticus tidvis kan forekomme i norske farvann (Bauer m.fl. 2006;Gjerde og Bøe 1981). I den nylig avsluttede studien ved Havforskningsinstituttet ble ulike Vibrio-arter isolert fra vann, fisk og skjell.…”

f. 1987) er for tiden PhD-student ved Universitetet i Tromsø med arbeidsplass ved Havforskningsinstituttet i Bergen. Han jobber med en kartlegging av en viktig sykdomsskapende bakterie, Klebsiella pneumoniae, i det marine miljø, samt gener som gir evne til å skape sykdom (virulens) og antibiotikaresistens hos disse.Bjørn Tore Lunestad (f. 1959) er seniorforsker ved Havforskningsinstituttet og Professor II ved Institutt for biovitenskap ved Universitetet i Bergen. Hans hovedaktivitet er knyttet til sjømatmikrobiologi og antibiotikaresistens i det marine miljø.Cecilie Smith Svanevik (f. 1984) er seniorforsker ved Havforskningsinstituttet, og arbeider med sjømatmikrobiologi og antibiotikaresistens i det marine miljø.

Assessment of food quality and microbial safety of brown macroalgae (Alaria esculenta and Saccharina latissima)

The methods employed were able to describe clearly the physical and microbial qualities of A. esculenta and S. latissima, and quality changes during processing. Based on the results, optimal cooking for a minimum of 15 min at 95 °C was suggested for S. latissima. Fresh and frozen A. esculenta showed the greenest color after heating for 5-9 s at a high temperature (> 85 °C). If a higher heat load is needed to achieve safe and stable food products, using fresh and not frozen A. esculenta is highly recommended, as fresh specimens remain green even after 15 min at 95 °C. © 2018 Society of Chemical Industry.

Several Vibrio spp. cause disease in marine fish populations, both wild and cultured. The most common disease, vibriosis, is caused by V. anguillarum. However, increase in the intensity of mariculture, combined with continuing improvements in bacterial systematics, expands the list of Vibrio spp. that cause fish disease. The bacterial pathogens, species of fish affected, virulence mechanisms, and disease treatment and prevention are included as topics of emphasis in this review, * + = 90% of all strains give a positive reaction, (+) = weak and/or delayed positive,-= 90 % of all strains are negative, V = variable reactions, A = acid, AG = acid + gas, R = resistant, S = sensitive; test procedures are given by West & Colwell (1984}. ** arginine dihydrolase, lysine and ornithine decarboxylase The natural habitat of Vibrio spp. is estuarine and marine water and sediment. Vibrios often occur in association with invertebrate and vertebrate animal surfaces and internal organs (Huq et al., 1983; Grimes et al, 1984b}, Stress can compromise the animal host, resulting in a commensal species switching to pathogenicity as the mode of interaction (Grimes et al., 1984c). * Formerly 1/. anguillarum biovar II Rodgers (1981) found V. alginolyticus to be a secondary invader of "red spot", a disease caused by V. "anguillarum. Gauthier & Clement (1979) observed a streptomycin-resistant strain of V. alginolyticus to be present not only in sediment but also water, when the water temperature exceeded 16 °C. However, food chain transmission was not observed when reconstructed marine food chains were studied in the laboratory (Gauthier & Clement, 1979). It is well established that V. alginolyticus can colonize the human gut (Sakazaki et al., 1963). In fact, Hiratsuka et al. (1980) observed the cause of acute enterocolitis in a patient who consumed trout roe contaminated with the same bacteria to be V. alginolyticus. More frequently, V. alginolyticus is associated with skin infections (Blake et al., 1980), such as conjunctivitis and stump ulcer cases described by Schmidt et al. (1979). Even though Blake et al. (1980) reported that little work has been done on virulence mechanisms, it is probable, based on available evidence, that the collagenase and several extracellular proteases produced by V, alginolyticus (Long et al., 1981) participate in the invasion of fish and human skin. Vibrio anguillarum This vibrio, the first recognized to be a fish pathogen, includes strains capable of utilizing arginine and tolerant of 6 % NaC1; some strains tolerate 8 % salt and others are capable of growth in the presence of trace amounts of salt, i.e., they are reported to grow
