Susceptibility of various cell lines to Neospora caninum tachyzoites cultivation
Neospora caninum is a coccidian protozoan parasite which is a major cause of bovine abortions and neonatal mortality in cattle, sheep, goat and horse. Occasionally, cultured cells are used for isolation and multiplication of the agent in vitro with several purposes. In this study the tachyzoite yields of N. caninum were compared in various cell cultures as the host cell lines. Among the cell cu...

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 کاملIntrauterine Neospora caninum inoculation of heifers and cows using contaminated semen with different numbers of tachyzoites.
OBJECTIVE To investigate the potential of different Neospora caninum tachyzoite doses to infect heifers (experiment 1) and cows (experiment 2) when administered in utero by artificial insemination via contaminated semen. METHODS In experiment 1, five groups of 5, 7, 8, 9, and 5 cyclic heifers were hormonally synchronized and artificially inseminated with semen containing 0 (A, controls), 10(2...
متن کاملHumoral immune response in pregnant heifers inoculated with Neospora caninum tachyzoites by conjunctival route.
The aim of this study was to compare systemic humoral immune responses in pregnant heifers inoculated with Neospora caninum tachyzoites by conjunctival and intravenous routes. Twenty nine heifers separated in three experimental groups were studied: Group 1 (n=10 animals) and Group 2 (n=9 animals) were inoculated with 10(8) of N. caninum tachyzoites by conjunctival and intravenous routes at 5th ...
