Restorative Effects of A Newly Synthesized Peptide, Obiopeptide-1, in Cyclophosphamide- or Carrageenan-pretreated Mice Infected with Opportunistic Bacteria
Provedor de dados: Obihiro University of Agriculture and Veterinary Medicine Academic Repository (OAK)
Autores: Fujii, Yasuhiro; Maki, Yoshiyuki; Ito, Masanari; Saito, Atsushi; Igarashi, Ikuo; Ono, Kenichiro; Itoh, Kikuji; Suzuki, Naoyoshi.
Large numbers of cyclophosphamide- or carrageenan-pretreated immunosuppressed adult ddY mice died within 10 days after inoculation with several species of opportunistic bacteria, including P. aeruginosa, K. pneumoniae, E. coli, S. aureus and methicillin resistant S. aureus. When immunosuppressed mice were administered bacteria in combination with two 100 μg/mouse intramuscular doses of a newly synthesized peptide, Obiopeptide-1 (OP-1), survival rates increased significantly. At 24 and 48 hours after intraperitoneal inoculation with P. aeruginosa, counts of viable organisms from the livers, spleens, lungs, hearts, and kidneys of mice that were administered cyclophosphamide in combination with OP-1 were significantly lower than counts from mice that were...

Autores: Shimada, Terumasa; Igarashi, Ikuo; Maki, Yoshiyuki; Claveria, Florencia G.; Saito, Atsushi; Suzuki, Naoyoshi.
Protective immune responses and the functional role of spleen cells in mice infected with Babesia rodhaini were examined with an in vitro proliferation assay systems and by in vivo passive transfer of spleen cells to uninfected mice. Mice that resolved primary babesial infection after chemotherapy (Babesia immune mice) had transient and low parasitemia after challenge infection and high rates (75%) of survival. Babesia hyperimmune mice, by contrast, had no detectable parasitemia after challenge and 100% survival. Proliferative response of spleen cells to Babesia lysate antigen (BLA) were determined for mice from both groups. This proliferative response was inhibited by treatment of spleen cells with anti-T cell serum and monoclonal antibody (MAb) to Lyt l...

Anil-Babesia rodhaini Monoclonal Antibodies: Effect against Babesia rodhaini and Cross-reactivity with Human Starin of Babesia microti
Provedor de dados: Obihiro University of Agriculture and Veterinary Medicine Academic Repository (OAK)
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,...
