The disease is associated to the infection with bacteria from the genus <em>Tenacibaculum<\/em> spp. In some marine areas or in recirculation systems, the infection severely threatens production with mortalities rising over 30%.<!--more--><\/p>\n<p>Pathological changes caused by tenacibaculosis are generally affecting fish from nursery phase to pre-growing fish, up to 80-100 grams average weight. Prevalence and intensity of the infections vary in relation with environmental parameters and zootechnical\/rearing conditions and are influenced with factors such as handling, mechanical lesions or stress and interfering parasitic infestations. Many studies support the hypothesis on <em>Tenacibaculum <\/em>spp. as opportunistic pathogen that primarly causes extensive skin lesions and gill abrasion, and subsequent systemic infections.<\/p>\n<p>Clinical signs of tenacibaculosis are variable according to fish species and type of infection. Affected fish show loss of appetite, become lethargic and show skin lesions around the eyes, on the head on the body surface described like ulcers, necrosis, eroded mouth, frayed fins and tail rot, and sometimes necrosis of the gills and eyes.<\/p>\n<p>Diagnosis is done on fresh smears from scrapping of the lesions by light microscopic observation directly or after quick staining followed by isolation of bacteria on selective media and identification based on proteomic fingerprinting using high-throughput mass spectrometry MALDI-TOF spectrometry or genomics. It confirms the presence or the emergence of different pathogenic species and most clinical cases present co-infections by at least two <em>Tenacibaculum <\/em>strains which may explain the evolution of clinical aspects, different pathogenicity patterns and poor treatment efficacy.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-3034\" src=\"http:\/\/www.medaid-h2020.eu\/wp-content\/uploads\/2019\/02\/cats-horz-2-1024x591.jpg\" alt=\"\" width=\"679\" height=\"392\" srcset=\"http:\/\/www.medaid-h2020.eu\/wp-content\/uploads\/2019\/02\/cats-horz-2-1024x591.jpg 1024w, http:\/\/www.medaid-h2020.eu\/wp-content\/uploads\/2019\/02\/cats-horz-2-300x173.jpg 300w, http:\/\/www.medaid-h2020.eu\/wp-content\/uploads\/2019\/02\/cats-horz-2-768x444.jpg 768w\" sizes=\"(max-width: 679px) 100vw, 679px\" \/><\/p>\n<p>To know more about <em>tenacibaculosis<\/em>, you can read on our blog a Mini-review prepared by Alain Le Breton:\u00a0<a href=\"http:\/\/www.medaid-h2020.eu\/index.php\/2019\/02\/05\/tenacibaculosis\/\" target=\"_blank\" rel=\"noopener\">http:\/\/www.medaid-h2020.eu\/index.php\/2019\/02\/05\/tenacibaculosis\/<\/a><\/p>\n<p><strong>1.
