The frequent association of human giardiasis with skin damages made the authors measure IgE serum levels by an ultramicroanalytical system in patients with clinical giardiasis, confirmed parasitologically. Possible stimulation of the total serum IgE response is studied, as well as its association with present allergic signs and the relationship with the(More)
A solid phase immunoradiometric assay (IRMA) for quantification of bovine albumin fraction V (Bov.Alb.FV) in antileptospirosical Cuban vaccine vaxSpiral is described in the present work. Anti-Bov.Alb.FV IgG raised against rabbit purified by affinity chromatography was used as first antibody. Anti-rabbit IgG labeled by Chloromine-T reaction was used as a(More)
In order to determine the IgA levels in secretions, the authors engaged themselves to obtain monoclonal antibodies against this immunoglobulin and to show their possible utilization in the development of quantitation methods. 6 monoclonal antibodies were obtained: one against the secretory component (SC) and five against the heavy-chain (HC) of IgA. IgA(More)
16 african patients with diagnosed W. bancroft's filariasis admitted to Pedro Kourí Tropical Medicine Institute were subjected to a therapeutic management with levamisole: 300 mg as starting dosage, and 150 mg/day for seven days. 11 patients had been previously treated with several courses of diethylcarbamazine (DEC), but a low microfilaremia persisted in(More)
We report the existence of high resistance to Melarsoprol and low resistance to Suramin in 11 Trypanosoma rhodesiense species. They were isolated from humans in the Tete province, Mozambique, and kept in mice at the Maputo National Health Institute. The preliminary results obtained with Suramin administered intracranially, are also reported.
Indirect immunofluorescence and simple immunodiffusion for trypanosomiasis were normalized. A high percent of patients were found to be positive, both by simple immunodiffusion and indirect immunofluorescence. The use of these techniques is recommended in epidemiological studies.
