X-linked hyper-IgM syndrome (XHM) is a combined immune deficiency disorder caused by mutations in CD40 ligand. We tested CP-870,893, a human CD40 agonist monoclonal antibody, in the treatment of two XHM patients with biliary Cryptosporidiosis. CP-870,893 activated B cells and APCs in vitro, restoring class switch recombination in XHM B cells and inducing cytokine secretion by monocytes. CP-870,...
Cryptosporidium is an obligate intracellular parasite that infects a wide variety of hosts. Twenty calves with cryptosporidiosis were divided into two groups. A single dose 2.5 mg/kg buparvaquone was administered intramuscularly to one group, while 100 mg/kg/day paromomycin orally the other group. The results obtained from study in which oocyst shedding and clinical parameters sucking reflex, m...
Time gap between oocyst shedding and antibody responses in mice infected with Cryptosporidium parvum
Sexual reproduction of Toxoplasma gondii occurs exclusively within enterocytes of the definitive felid host. The resulting immature oocysts are excreted into the environment during defecation, where in the days following, they undergo a complex developmental process. Within each oocyst, this culminates in the generation of two sporocysts, each containing 4 sporozoites. A single felid host is ca...
Several gene sequences of parasitic protozoa belonging to protein kinase gene families and epidermal growth factor (EGF)-like peptides, which act via binding to receptor tyrosine kinases of the EGF receptor (EGFR) family, appear to mediate host-protozoan interactions. As a clue to EGFR protein tyrosine kinase (PTK) mediation and a novel approach for identifying anticoccidial agents, activities ...
