Expression, purification and antigenicity of Neospora caninum-antigens using silkworm larvae targeting for subunit vaccines.

Bombyx mori nucleopolyhedrovirus displaying neospora caninum antigens as a vaccine candidate against N. caninum infection in mice.

Baculovirus display systems have been utilized for cell-specific gene transfer, regenerative medicine, and as vaccine vectors. In particular, baculovirus particles displaying surface antigens have been used as vaccines against some parasites and viruses. In this study, Bombyx mori nucleopolyhedrovirus (BmNPV) particles displaying Neospora caninum antigens (NcSAG1, NcSRS2, and NcMIC3) purified f...

Towards a preventive strategy for neosporosis: challenges and future perspectives for vaccine development against infection with Neospora caninum

Neosporosis is caused by the intracellular protozoan parasite Neospora caninum. This major disease-causing pathogen is responsible for inducing abortion in cattle, and these adverse events occur sporadically all over the world, including Japan. Currently, there are no vaccines on the market against infection with N. caninum. Because live and attenuated vaccines against N. caninum have had safet...

Vaccines against a Major Cause of Abortion in Cattle, Neospora caninum Infection

Neosporosis, caused by the apicomplexan parasite Neospora caninum, represents one of the economically most important causes of abortion in cattle. During pregnancy, the parasite infects the placental tissue and the fetus, which can lead to stillbirth, abortion, or birth of weak calves. Alternatively, calves are born without clinical symptoms, but they can carry over the parasite to the next gen...

Molecular detection of Neospora caninum from naturally infected dogs in Lorestan province, West of Iran

Neospora caninum is a coccidian protozoan that causes abortion in dairy and beef cattle and neurological disorders in dogs and horses. To identify N. caninum oocysts in the dog feces the molecular approaches are known as sensitive methods that specifically detect the oocysts. In present study, a polymerase chain reaction (PCR) targeting N. caninum specific Nc5 genomic fragment was performed to ...
