Anil-Babesia rodhaini Monoclonal Antibodies: Effect against Babesia rodhaini and Cross-reactivity with Human Starin of Babesia microti
Provedor de dados: 19
Autores: Claveria, Florencia G.; Omata, Yoshitaka; Takehara, Tokuma; Saito, Atsushi; Maki, Yoshiyuki; Igarashi, Ikuo; Suzuki, Naoyoshi.
Anti-Babesia rodhaini monoclonal antibodies (mAb), namely: 1-E7, 2-H2 and 3-B8, significantly suppressed the development of high parasitemia in BALB/c mice infected with B. rodhaini and all mAb-treated mice survived the infection. While, only monoclonal antibody 3-B8 showed some inhibitory effect against Babesia microti, with mice showing high parasitemia of 18.04 ± 2.69 %, at 9 days post-exposure. Westernblot analysis of B. rodhaini and B. microti parasite extract reacted with anti-B. rodhaini monoclonal antibodies showed cross-reactive bands of molecular weights 62 and 55 kilodaltons. Comparison of the antigenic components of B. rodhaini and B. microti using polyspecific sera revealed several shared or common parasite antigens of molecular weights 62,...

Toxoplasma gondii: DNA vaccination with genes encoding antigens MIC2, M2AP, AMA1 and BAG1 and evaluation of their immunogenic potential
Provedor de dados: 19
Autores: Dautu, George; Munyaka, Biscah; Carmen, Gabriella; Zhang, Guohong; Omata, Yoshitaka; Xuan, Xuenan; Igarashi, Makoto.
A combination of antigenic regions of microneme proteins have been previously reported as being protective against chronic toxoplasmosis. In this work, we evaluated immune responses induced by immunizing BALB/c and C57BL/6 mice intradermally with plasmid DNA encoding the protein sequences of Toxoplasma gondii AMA1, MIC2, M2AP and BAG1. Mice immunized with the AMA1 gene developed high levels of serum IgG2a and c antibodies as well as cellular immune responses associated with IFN-γ synthesis suggesting a modulated Th1 type of response. Immunization with the AMA1 gene resulted in a partial but significant protection against the acute phase of toxoplasmosis compared to MIC2, M2AP and BAG1 genes. Therefore, the AMA1 gene appears to generate a strong specific...

Possibility of Neospora caninum infection by venereal transmission in CB-17 scid mice
Provedor de dados: 19
Autores: Masuda, Tsuneyuki; Kobayashi, Yoshiyasu; Maeda, Ryuichiro; Omata, Yoshitaka.
CB-17 scid and BALB/c male mice were inoculated intraperitoneally with Neospora caninum to examine the possibility of its venereal transmission. Some of these mice were killed on days 7 and 20 post-inoculation to examine the genital organs for presence of the parasite. The remaining scid male mice were housed with non-infected female mice from day 7 p.i. and kept with them for 14 days. These scid mice died between days 28 and 35 p.i. N. caninum DNA was detected in the testis of mice on days 7 and 20 p.i. by PCR and tachyzoite viability was determined by bioassay conducted by means of mouse inoculation. Microscopically, fewer tachyzoites were detected in the testis obtained on day 20 p.i., than in other organs. The inoculated BALB/c male mice survived until...
