background and objective: streptococcosis/lactococcosis is the cause of high morbidity and mortality in aquaculture sector and to date a number of species of streptococcus and lactococcus genera including s. iniae, s. agalactiae, s. dysagalactiae, s. parauberis, s. feacalis, l. garvieae and l. lactis have been discriminated as the cause of disease in aquatic animals. despite the use of diagnost...

This study was aimed to determine the current antibiotic resistance of Lactococcus garvieae, which causes significant economic losses in rainbow trout (Oncorhynchus mykiss) farms. For study, three farms located around a stream were visited two consecutive disease outbreaks. Bacteria isolated from diseased fish and all bacterial isolates identified using conventional molecular methods. Then, the...

The total haemocyte count (THC), phenoloxidase activity, respiratory bursts (release of superoxide anions), superoxide dismutase (SOD) activity, and phagocytic activity and clearance efficiency to the pathogen Lactococcus garvieae were measured when freshwater giant prawns Macrobrachium rosenbergii (18.2+/-2.1 g) were individually reared in water containing concentrations of trichlorfon of 0, 0...

The phenotypic and genetic analysis results for 84 isolates of Lactococcus garvieae (including 62 strains from trout with lactococcosis from four different countries, 7 strains from cows and water buffalos with subclinical mastitis, 3 from water, and 10 from human clinical samples) are presented. There was great phenotypic heterogeneity (13 different biotypes) based on the acidification of sacc...

A 45-year-old male with a prosthetic aortic valve presented to the hospital with several months of generalized malaise. On admission, he was noted to have anemia of unclear etiology and subsequently became febrile with multiple blood cultures growing Lactococcus garvieae. Inpatient workup was concerning for infectious endocarditis (IE) secondary to Lactococcus. The patient was discharged home w...

Studi sampel dimulai pada Juli 2018 dan selesai September 2018. pengambilan dilakukan komersial distrik Kemer, Korkuteli, Serik Manavgat Antalya. Sembilan puluh selama masa studi. Bo...

rinbow trout (oncorhynchus mykiss) is an important fish species in aquaculture. the bacterial disease caused the decline in the production of this fish. lactococcus garvieae is one of the most serious infectious agents that caused disease with economical losses in fish farms. streptococosis have signs similar to lactococcosis. therefore the definite diagnosis is sometimes complicated. in the la...
