摘要:
The present invention provides a method for the prevention or the treatment of an infection of fishes with nodaviruses or a disease such as, for example, viral nervous necrosis or the like, caused by an infection with nodaviruses. The infection of fishes with nodavirus or the outbreak of a disease including viral nervous necrosis or the like caused by the infection with nodaviruses can be prevented or treated by transdermally administering fishes with aquabirnaviruses, for example, by injection, or dipping fishes in a solution containing an aquabirnavirus or supplying fishes with a feed containing an aquabirnavirus.

Methods of producing, propagating and multiplying viruses, methods of identifying the presence of a virus in a sample, specifically methods using Japanese eel cell cultures. Also provided are an isolated Japanese eel cell culture, optionally infected with a virus, vaccines comprising viruses grown according to the methods of the invention, and a kit for propagating viruses comprising the Japanese eel cell culture. The virus may be a fish virus such as nodavirus, Infectious Pancreatic Necrosis Virus (IPNV) and Salmon Pancreas Disease Virus (SPDV).
摘要:
The disclosure provides recombinant viral vectors and attenuated viruses and viral vaccines comprising a virus lacking a functional viral RNA suppressor of host RNAi.
摘要:
Disclosed are interactions between different betanodaviruses during infection of cells “in vitro” and in European sea bass. More specifically, fish administered striped jack nervous necrosis viruses (SJNNV), which are then exposed to red-spotted grouper nervous necrosis viruses (RGNNV), have fewer symptoms of disease associated with RGNNV and/or increased survival as compared to fish not administered SJNNV prior to exposure to RGNNV.
摘要:
A vaccine against nodavirus infection in fish can be produced by inactivating the virus using an aziridine compound. This vaccine can be used to prevent Viral Nervous Necrosis (VNN) in a variety of fish species.
摘要:
The present invention relates to an immunogenic composition for fish comprising nodavirus virus-like particles (VLPs) formed with nodavirus capsid protein assembly, for use as a vaccine. This composition is suitable for administration to fish via the intramuscular or intraperitoneal route, or by bath and/or via the oral route. The invention also relates to the use of such VPLs for the manufacturing of a vaccine for treating or preventing fish against a nodavirus infection. Fish farming baths and concentrates comprising the nodavirus VLP composition, as well as fish farming methods, are also encompassed in the present invention.

摘要:
Disclosed is a gene multiple insertion cassette set including rDNA NTS fragments and an auxotrophic selection marker having an incomplete promoter is developed, and a safe oral recombinant strain having no antibiotic resistant marker is constructed by multiple insertion of an optimum number of the developed gene multiple insertion cassette sets into chromosomes of a Saccharomyces cerevisiae strain, a vaccine composition including, as an active ingredient, the above strain, a culture product thereof, a cell lysate, or nodavirus capsid protein (NNVcp) isolated and purified therefrom, and a composition for feed addition including, as an active ingredient, the above strain, a culture product thereof, a cell lysate, or squalene or oxidosqualene isolated and purified therefrom.
摘要:
The present invention relates to stable compositions comprising acellular pertussis antigens that have not been cross-linked with a cross-linking agent such as formaldehyde or glutaraldehyde and their use as acellular pertussis components in combination vaccines. Processes for preparing these antigens and compositions are also disclosed.
摘要:
A composition for oral immunization comprising recombinant proteins AHMA and FP that afford protection from bacteria and protozoan ectoparasites respectively is disclosed. Also disclosed are compositions that have in addition, inactivated viruses and killed bacteria affording a wider spectrum of protection against infections that predominantly afflict aquatic species. Method of making these compositions and administering them either directly or by incorporating them into feed, as also the use of such compositions for treating animals in need of such treatment are also disclosed.
