Lactococcus garvieae, Lyophilized qPCR Overview Lactococcus garvieae is a Gram-positive coccus that causes lactococcosis, typically a haemorrhagic septicemia in fish, and is emerging in marine species including sea bass (rarely reported) and trout. When infection occurs in grow-out stages, clinical signs may include haemorrhages, exophthalmia (bulging eyes), abnormal swimming behaviour, lethargy and high mortality in some […]

Sparicotyle chrysophrii, Lyophilized qPCR Overview Sparicotyle chrysophrii is a gill ectoparasitic monogenean (family Microcotylidae) that infects gilthead sea bream and to a lesser extent sea bass, especially during the grow-out phase. All life stages can be affected, though the parasite load and gill damage tend to accumulate in larger fish. Clinically, infections lead to anemia, severe

Vibrio harveyi, Lyophilized qPCR Overview Vibrio harveyi is a motile, Gram-negative marine bacterium implicated in vibriosis of fish and invertebrates. In sea bass and sea bream, it can infect at all life-stages and is often associated with skin lesions, fin necrosis, eye opacity, lethargy, and haemorrhages under stress-prone, warm‐water conditions. No widely deployed commercial vaccine exists

Photobacterium damselae, Lyophilized qPCR Overview Photobacterium damselae is a halophilic, Gram-negative rod that causes photobacteriosis (also called fish pasteurellosis) in marine species including sea bass and sea bream. It commonly affects juveniles and adults, with outbreaks often linked to elevated water temperature (>18–20 °C). Clinically one sees fish with abdominal distension/ascites, external haemorrhages, skin ulcers, and

Tenacibaculum maritimum, Lyophilized qPCR Overview Tenacibaculum maritimum is a Gram-negative, filamentous marine bacterium that causes the disease known as tenacibaculosis in many cultured marine fish species including sea bass (European sea bass) and sea bream (Gilthead sea bream). It affects all life stages, though juveniles are more susceptible (weights ~2-80 g) under conditions of stress, elevated

Neoparamoeba perurans (Amoebic Gill Disease, AGD), Lyophilized qPCR Overview Neoparamoeba perurans is a free-living marine amoeba that causes Amoebic Gill Disease (AGD) in farmed marine salmonids (especially Atlantic salmon). AGD is characterised by white mucoid patches on the gills, gill epithelial hyperplasia and fusion, respiratory distress, lethargy and reduced growth. Environmental factors such as higher water

Piscirickettsia salmonis, Lyophilized qPCR Overview Piscirickettsia salmonis is a facultative intracellular Gram-negative bacterium that causes Piscirickettsiosis (also called Salmon Rickettsial Septicaemia, SRS) in farmed salmonids, especially Atlantic and Coho salmon. The disease typically occurs in seawater grow-out and is characterised by lethargy, reduced appetite, skin lesions/ulcers, kidney damage, anemia and high mortality (sometimes up to ~90%

Yersinia ruckeri, Lyophilized qPCR Overview Yersinia ruckeri is a Gram-negative bacterium causing Enteric Redmouth Disease (ERM) in salmonids such as rainbow trout and occasionally Atlantic salmon. Characteristic signs include haemorrhages in the mouth, eyes (exophthalmia), darkened skin, lethargy and internal bleeding. The disease remains of commercial importance in freshwater and early grow-out phases, and is managed

Renibacterium salmoninarum, Lyophilized qPCR Overview Renibacterium salmoninarum is the Gram-positive intracellular bacterium responsible for Bacterial Kidney Disease (BKD) in salmonids. The infection is often chronic and insidious, affecting older juveniles and adults, with signs such as white granulomas in the kidney and spleen, anemia, reduced growth and low-level mortalities rather than sudden outbreaks. Because fish may

Aeromonas salmonicida, Lyophilized qPCR Overview Aeromonas salmonicida is a Gram-negative rod that causes furunculosis—a systemic disease in salmonids. The disease features external signs such as ulcers (“furuncles”), hemorrhages, darkened skin, distended abdomen, and internal signs like swollen kidney/spleen, and haemorrhagic septicemia. Although historically devastating, many aquaculture systems now manage furunculosis with vaccinations and improved husbandry. The
