Protective efficacy of vaccination with Neospora caninum multiple recombinant antigens against experimental Neospora caninum infection.
Protective efficacy of vaccination with Neospora caninum multiple recombinant antigens against N. caninum infection was evaluated in vitro and in vivo. Two major immunodominant surface antigens (NcSAG1 and NcSRS2) and two dense granule proteins (NcDG1 and NcDG2) of N. caninum tachyzoites were expressed in E. coli, respectively. An in vitro neutralization assay using polyclonal antisera raised a...
متن کاملImmunization with oligomannose-coated liposome-entrapped dense granule protein 7 protects dams and offspring from Neospora caninum infection in mice.
The present study demonstrates that the subcutaneous administration of Neospora caninum dense granule protein 7 (NcGRA7) entrapped in liposomes coated with mannotriose strongly induces the parasite-specific T-helper type 1 immune response and humoral antibody in mice. Although anti-NcGRA7 immunoglobulin G1 antibody production was induced in mice injected with NcGRA7 alone, the dams and offsprin...
متن کاملNeospora caninum and neosporosis
Neospora caninum is a protozoan cyst forming apicomplexan parasite that causes neosporosis, notably in cattle (Bos taurus) and domestic dogs (Canis familiaris) [1,2]. It is closely related to Toxoplasma gondii and has emerged as a major cause of reproductive failure in cattle worldwide [2]. The parasite was first described in a dog with encephalomyelitis and myositis [1] and was later described...
متن کاملNeospora caninum and Wildlife
Bovine neosporosis caused by Neospora caninum is among the main causes of abortion in cattle nowadays. At present there is no effective treatment or vaccine. Serological evidence in domestic, wild, and zoo animals indicates that many species have been exposed to this parasite. However, many aspects of the life cycle of N. caninum are unknown and the role of wildlife in the life cycle of N. cani...
متن کاملImmunization of mice with plasmid DNA coding for NcGRA7 or NcsHSP33 confers partial protection against vertical transmission of Neospora caninum.
The purpose of the present study was to use direct plasmid deoxyribonucleic acid (DNA) injection to identify specific antigens that confer protection against congenital transfer of Neospora caninum. Inbred BALB/c mice were vaccinated before pregnancy with a recombinant plasmid containing sequences encoding N. caninum antigen NcGRA7 or NcsHSP33. The mice were challenged with N. caninum tachyzoit...
