Efficacy of a whole cell Lactococcus garvieae vaccine in rainbow trout (Oncorhynchus tnykiss)

In this research, a whole cell bacterin vaccine was prepared from Lactococcus garvieae isolated from rainbow trout farms in Turkey after an epizootic outbreak. The efficacy of vaccine on lactococcosis was tested in rainbow trout (Oncorhynchus myciss). In 25, 76 and 125 days following i.p. injection vaccination, the groups of vaccinates and non vaccinates were challenged by i.p. injection with 0.1 mL of the Lactococcus garvieae strain at concentration of approximately 10 6 cells mL -1 and monitored daily for clinical signs and mortality for 21 days. Dead fish were examined to confirm the reisolation of the inoculated strain from the internal organs. Calculated RPS values for day 25, 76 and 125 were found 83.3, 75 and 68%, respectively. © Medwell Journals, 2012

Ectoparasitic sea lice, Caligus minimus (Otto 1821, Copepoda: Caligidae) on Brawn wrasse, Labrus merula L., in Izmir Bay, Aegean Sea

WOS: 000306833700004This paper reports on the species of Caligus minimus of the genus Caligus (Siphonostomatoida: Caligidae), parasitic on marine fish, brawn wrasse (Labrus merula), genus Labridae, of Izmir Bay, Aegean Sea. The sea lice, C. minimus, is identified from the gill and external surfaces of the brawn wrasse (total length, 30 cm; weight, 210 gr.), particularly on its head. The entire collection of sea lice consists of 11-12 specimens, all of which are female. Ectoparasitic copepods especially belong to the Caligidae family, the most common crustacean parasites on fish. C. minimus can be found in Atlantic coasts, British waters, the North Sea, and the Mediterranean Sea. C. minimus ectoparasite is a host and mainly recorded on Perciformes, such as Dicentrarchus labrax, Pagellus bogaraveo, Umbrina cirrosa, and Mugil cephalus. Recently, in both sides of the Aegean Sea, C. minimus has been identified from cultured marine fish, mainly D. labrax. The intensity of the infection is apparent on adult fish, especially between winter and early summer. C. minimus is the first record on brawn wrasse caught by gill nets from the Urla coasts in Izmir Bay, Aegean Sea in March 2010

Mix Infections in Rainbow Trout (Oncorhynchus mykiss Walbaum): Lactococcus garvieae and Vibrio anguillarum O1

WOS: 000288717200016Vibrio anguillarum and Lactococcus garvieae which causes mixed infections were isolated for the first time from rainbow trout farms in the Southwest of Turkey. The outbreak occurred at 15 degrees C water temperature in June 2009. The diseased fish showed erratic swimming, dark discoloration, bilateral exopthalmia, haemorhages on the fins, operculum, the liver, spleen and lower intestines with mortality ranging from 30-50% in the pools. The identities of the isolates were confirmed as V. anguillarum O1 and L. garvieae by biochemical and serological tests using API 20 Strep, API 20 E and API Strept system test strips and also V. anguillarum (ATTC 43305) used as antigens for agglutination. The epizootic disease was effectively controlled by oral administration of enrofloxacin
