Experimental infection with Neospora caninum in pregnant bitches.
In this study, transplacental transmission of Neospora caninum in bitches at different stages of pregnancy was evaluated. Three bitches were inoculated in the 3rd week and three in the 6th week of gestation with 10(8) tachyzoites of N. caninum (Nc-1 strain). All the infected bitches and at least one of their offspring presented anti-N. caninum antibodies according to the indirect fluorescent an...
متن کاملProtective 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 کاملExperimental infection of sheep with Neospora caninum oocysts.
The purpose of the present study was to investigate the potential of Neospora caninum oocysts to infect sheep and determine whether N. caninum DNA could be detected by polymerase chain reaction (PCR) assay in blood and brain of sheep after oocyst inoculation. Six ewes were inoculated per os with 10(4) N. caninum oocysts, whereas 2 ewes served as uninoculated controls. All sheep were bled weekly...
متن کاملSeminested PCR for Diagnosis of Neospora caninum Infection in Cattle.
Neospora caninum, an apicomplexan protozoan, is regarded as a major cause of abortion and stillbirth in cattle in countries world-wide. The ability to detection N.caninum in tissue samples can be a useful detection diagnostic tool for use in the study of the pathogenicity, immunoprophylaxis, and treatment of Neospora infection. However, molecular biology is one of the most sensitive tools for d...
متن کاملEffects of Neospora caninum infection at mid-gestation on placenta in a pregnant mouse model.
Neospora caninum is one of the more-efficient transplacentally-transmitted organisms. The goal of the present study was to investigate the pathologic and immunologic changes that occur at the materno-fetal interphase in pregnant BALB/c mice infected with N. caninum at mid-gestation. Parasite DNA was detected in feto-placentary units 3 days post-infection (PI). On day 7 PI, the DNA detection lev...
