The reference strains of Enterococcus seriolicida (ATCC 49156T) (T = type strain) and of Lactococcus garvieae (ATCC 43921T) and 30 field strains of Gram-positive cocci isolated from diseased rainbow trout in Italy were found to be phenotypically (API 20 STREPT and API 50 CH) and genetically (DNA-DNA hybridization) similar. The high DNA-DNA homologies (70–100%) and the low ΔTm(e) (less than 1.1°C) among these strains showed that Enterococcus seriolicida and Lactococcus garvieae are synonyms, describing a single bacterial species. E. seriolicida strains should be classified as L. garvieae, which must be considered as a major pathogen of freshwater and salt water fish with a world-wide distribution.
Fish: a potential source of bacterial pathogens for human beings
Veterinární medicína, 2012
Human infections caused by pathogens transmitted from fish or the aquatic environment are quite common and depend on the season, patients’ contact with fish and related environment, dietary habits and the immune system status of the exposed individual. They are often bacterial species facultatively pathogenic for both fish and human beings and may be isolated from fish without apparent symptoms of the disease. The infection source may be fish kept for both for food and as a hobby. Human infections and intoxications with the following bacteria have been recorded: Mycobacterium spp., Streptococcus iniae, Photobacterium damselae, Vibrio alginolyticus, V. vulnificus, V. parahaemolyticus, V. cholerae, Erysipelothrix rhusiopathiae, Escherichia coli, Aeromonas spp., Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, Clostridium botulinum, C. perfringens, Campylobacter jejuni, Delftia acidovorans, Edwardsiella tarda, Legionella pneumophila, and Plesiomonas shigelloides. Fish ti...

Prevalence and distribution of pathogenic bacteria found in fish and fishery products: A review
2020
Fishes are among one of the major sources of food for many counties globally and a vital source of protein. Fishes are known to be carriers and vectors of pathogenic bacteria that are of major concern to consumers and public health. Contamination of pathogenic bacteria can arise from the aquatic ecosystem via pollution from domestic, industrial and agricultural discharges, contamination from soil, and also from the processing and marketing environments. Pathogenic bacteria that are associated with fishes and their related products include Gram negative bacteria like Vibrio spp., Escherichia coli, Salmonella spp., Shigella spp., Staphylococcus aureus, Pseudomonas spp., Listeria monocytogenes, C. botulinum and C. perfringens dominating the micro-flora of fishes. Members of the Enterobacteriaceae family are among one of the most prevalent pathogenic bacteria isolated from fishes that pose serious health problems. Several parts of fishes including the skin/scales, flesh, intestines, and...
Lactococcus garvieae in fish: A review
Comparative Immunology, Microbiology and Infectious Diseases, 2006
Lactococcus garvieae is the etiological agent of Lactococcosis, an emergent disease which affects many fish species and causes important economic losses both in marine and freshwater aquaculture when water temperature increases over 16 1C in summer months. Normally, it causes a hyperacute and haemorrhagic septicemia. This paper presents a state of the art review of fish Lactococcosis including aspects such as pathogen characterization, pathogenesis, epidemiology, diagnosis and control measures of the disease in farmed fish.
Bacterial Infections Affecting Marine Fishes in Egypt
Some fish species are suffering from continuous depletion due to devastating environmental changes at their native aquatic environment. Qarun Lake and Suez Gulf are among the most vulnerable areas. Thus, representative fish samples from those areas were inspected for the presence of any fish pathogenic bacteria. The inspected samples included six different species; Epinephelus tuvina, Siganus rivulatus, and Dedlechilus labiosus native to Suez Gulf at Suez governorate; Tilapia zilli, Mugil capito and Solea vulgaris native to Qarun Lake at El-Fayoum governorate. A total of 600 samples were examined throughout the different year seasons. Gram positive and negative fish pathogenic bacteria were isolated from a total of 245 fish sample. Among those samples, the following bacteria were retrieved in the following percentages respectively, 17.55% (V. anguillarum), 16.73% (V. alginolyticus), 15.51% (P. piscicida), 15.91% (Ps. fluorescens), 13.46% (S. fecalis), 11.02% (A. hydrophila), 6.12% (A. sobria) and 3.67% were infected with Staph. aureus. The Siganus rivulatus was the highest infected fish species with a prevalence of 8.33%, while Mugil capito was the lowest infected species (5.67 %). The highest total prevalence of bacterial infection was recorded in summer season (40.81%) while the lowest was recorded in winter (15.91%). The aforementioned bacterial isolates were successfully re-isolated from experimentally infected fish. The retrieved isolates were matched against standard isolates as well as confirmed to be positive using semiautomated (API 20 E) and conventional biochemical tests.
BACTERIOLOGICAL AND MOLECULAR STUDIES ON BACTERIATRANSMITTED FROM FISHES TO HUMAN.
A total of 1500 samples from 300 apparently healthy fish (280 Tilapia nilotica and 20 Catfish) were collected randomly from some markets and farms at Kafr El-sheikh governorate, Egypt. Also 50 human skin swabs were collected. These samples were collected to isolate and characterize bacteria transmitted from fish to human. In this study the prevalence of Staphylococcus aureus, Escherichia coli, Salmonella spp., Pseudomonas spp., Aeromonas spp. and Edwardseillatarda in Tilapia were 8.2, 21.4, 19, 11.4, 10 and 1.1% respectively, the prevalence of theses pathogens in Catfish were 5, 75, 60, 15, 10 and 0% respectively while its prevalence in human were 8, 24, 20, 12, 0 and 0% respectively. Escherichia coli serotype isolates from fish were O153, O1, O125 and O78. Salmonella serotype isolates from fish were Salmonellainganda, Salmonellatyphimurium and Salmonella Kentucky and Salmonellamolade. Results showed that all the eight isolates of Staphylococcusaureus subjected for determination of clfA gene were positive and negative to Hla gene, all the five Salmonella isolates were positive to invA and sefA genes and only one from four isolates of Escherichia coli was positive to eaeA gene and the four isolates were negative to Hly gene.
Enterococcus seriolicida sp. nov. a Fish Pathogen
1991
The properties and taxonomic position of bacterial strains isolated from diseased specimens of cultured yellowtail and eels were examined. The isolates were gram-positive, short-chain-forming, catalase-negative, facultatively anaerobic cocci. Growth at 10 and 45°C in 6.5% NaCl (pH 9.6) with 40% bile and in 0.1% methylene blue-milk were both positive. The isolates could be distinguished from other species of the genus Enterococcus by several biochemical characteristics and by Lancefield's group antigen. Guanine-plus-cytosine content of DNA was 44 mol% as determined by the thermal melting temperature. The value for DNA-DNA hybridization was sufficiently low to warrant distinguishing this species from reported Enterococcus species. The name Enterococcus seriolicida is proposed. The type strain is YT-3 (=ATCC 49156).
