Catalogue of the ectoparasitic insects of the bats of Argentina

Abstract

Sections obtained from lymphoid tissues fixed immediately after biopsy in Bouin's fluid and embedded in paraplast may be used to visualize the immunosecretory cells with classical direct immunofluorescence. A comparative study of the same fragments processed according to the frozen section method followed by acetone fixation or according to Sainte-Marie's method confirms the value and the advantages of the proposed technique. Early fixation of thin fragments seems to be the main point.
