Isoenzymes of human lice: pediculus humanus and P. capitis.

Human lice (Phthiraptera: Pediculidae) from Africa, America and Europe were electrophoresed for 28 enzymes, with special interest in metabolic factors likely to be involved with insecticide resistance. Zymogram profiles of the body louse (Pediculus humanus L. from France and U.

Human African trypanosomiasis: presence of antibodies to galactocerebrosides.

Improvements were made in the immunodetection of anti-galactocerebroside (anti-GalC) antibody in sera of patients with human African trypanosomiasis by thin-layer chromatography, enzyme-linked immunosorbent assay, and immunoadsorption. Rabbit anti-GalC antibodies were used to standardize these techniques and demonstrate their specificity. Anti-GalC antibodies were found in the sera of 42.

Galactocerebrosides are antigens for immunoglobulins in sera of an experimental model of trypanosomiasis in sheep.

In an experimental model of human African trypanosomiasis in sheep inoculated with Trypanosoma brucei brucei, we report an immunoglobulin reactivity towards central nervous system (CNS) glycolipids. Immunocharacterization of the glycolipid antigens was performed on thin-layer chromatography using peroxidase-labelled second antibody. An immunoreactivity against galactocerebroside antigens was observed in inoculated animals up to a dilution of 1:600 and was suppressed after immunoadsorption of sera on pure galactocerebrosides.

[Trial of pentamidine in the treatment of trypanosomiasis of sheep inoculated with Trypanosoma brucei brucei].

An experimental study was carried out using 5 Trypanosoma brucei brucei subcutaneously infected sheep. Pentamidine treatment appeared in the CSF. Two animals were injected daily for 10 days and they died with drug intoxication.
