“…The localization of Salmonella in fish may differ, and pathogens most frequently were isolated from the alimentary tract (64/150, 41.3 %), compared to other parts of fish-skin (48/150, 32 %) and gills (20/150, 26.7 %) (Hatha and Lakshmanaperumalsamy 1997). Youssef et al (1992) also reported extended survival of Salmonella in the alimentary tract of catfish.…”

“…It is generally accepted that bacteria found on fish skin are the same as those found in the contaminated water, including such genera and species as Aeromonas spp. (Aeromonas hydrophila, A. bestiarum, A. caviae, A. jandaei, A. schubertii, A. veronii), Flexibacter spp., Proteus spp., Providencia spp., Psychrobacter spp., Moraxella spp., Pseudomona fluorescens, Acinetobacter johnsonii, Alcaligenes piechaudii, Enterobacter aerogenes, Escherichia coli, Micrococcus luteus, and Vibrio fluvialis (Christensen 1977;Allen et al 1983;Youssef et al 1992;Diler et al 2000;Gonzalez et al 2000Gonzalez et al , 2001Zmyslowska et al 2001).…”

Fish plays an important role in the human diet, and there is an observed increase in the consumption of fish per capita in Europe. However, intensive growth of industry and agriculture may cause contamination of natural and humanmade aquatic environments, and may affect not only the health of fish, but also raise safety concerns with regard to fish used for human consumption. It is well known that fish and fish products are often associated with human diseases. Thus, it is necessary to study the prevalence of pathogens in fish to ensure the safety of fish products and environments. Microbial assessment of fish also gives additional information about the hygienic status of environments, including lakes, rivers, ponds, and fish farms. Detection of pathogenic microorganisms or changes in natural microflora in the water environment could be an important indicator of possible contamination. The aim of this review was to describe and discuss the five most relevant bacterial genera and species linked to aquatic environments-Vibrio spp., Listeria monocytogenes, Yersinia spp., pathogenic Salmonella serovars, and Clostridium botulinum-causing human foodborne diseases.

A total of 360 samples, including 105 marine fish, 25 prawns, 50 squid, 50 octopus, 30 mussels and 100 freshwater fish were examined microbiologically for the presence of microorganisms potentially pathogenic. All samples were examined following standard microbiological procedures. The isolated microorganisms were: Aeromonas hydrophilia (38–93%), Klebsiella ozonae (1–40%), Escherichia coli (14–87%), Yersinia enterocolitica (0–40%), Hafnia alvei (0–36.6%), Enterobacter agglomerans (0–42%), Citrobacter freundii (0–46%), Proteus vulgaris (15–80%), Proteus mirabilis (7–82%), Morganella morganii (0–30%), Pseudomonas fluorescens (0–34%), Pseudomonas putida (0–6%), Plesiomonas shigelloides (0–4%), Listeria innocua (1–3.3%), Vibrio parahaemolyticus (0–2%), Clostridium perfringens (0–1%), Staphylococcus aureus (0–80%) and Candida quillermondi (0–1%), Candida albicans (0–1%), Penicillium oxalicum (0–1%) and Penicillium italicum (0–12%).

“…In aquaculture, the advent of intensive aquaculture practices led to the outbreak of diseases in all forms of practices ranging from freshwater to marine and warm water to cold water fish (Nicolas, Robic & Ansquer 1989; Youssef, E1‐Timawy & Ahmed 1992; Keskin, Keskin & Rosenrhal 1994; Press & Lillehaug 1995; Karunasagar & Karunasagar 1999). The GI tract is believed to be the major route for the onset of diseases like vibriosis, furunculosis, enteric septicaemia and aeromoniasis in fish.…”

The gastrointestinal (GI) tract of an animal consists of a very complex and dynamic microbial ecosystem that is very important from a nutritional, physiological and pathological point of view. A wide range of microbes derived from the surrounding aquatic environment, soil/sediment and feed are found to colonize in the GI tract of fish. Among the microbial groups, bacteria (aerobic, facultative anaerobic and obligate aneraobic forms) are the principal colonizers in the GI tract of fish, and in some fish, yeasts are also reported. The common bacterial colonizers in the GI tract of freshwater and marine fish include Vibrio, Aeromonas, Flavobacterium, Plesiomonas, Pseudomonas, Enterobacteriaceae, Micrococcus, Acinetobacter, Clostridium, Fusarium and Bacteroides, which may vary from species to species as well as environmental conditions. Besides, several unknown bacteria belonging to Mycoplasma, Arthrobacter, Brochothrix, Jeotgailbacillus, Ochrobactrum, Psychrobacter and Sejongia species in the GI tract of different fish species have now been identified successfully using culture‐independent techniques. Gnotobiotic and conventional studies indicate the involvement of GI microbiota in fish nutrition, epithelial development, immunity as well as disease outbreak. This review also highlights the need for manipulating the gut microbiota with useful beneficial microbes through probiotic, prebiotic and synbiotic concepts for better fish health management.
