Area of Science:

  • Malacology
  • Histology
  • Biological Sciences

Background:

  • Accurate tissue fixation is crucial for histological examination of gastropods.
  • Traditional methods for Biomphalaria glabrata fixation can be time-consuming and yield suboptimal results.

Purpose of the Study:

  • To describe a new, practical technique for the fixation of Biomphalaria glabrata for histological studies.
  • To evaluate the efficacy of this novel fixation method compared to conventional approaches.

Main Methods:

  • The described technique involves creating several small external holes in the snail's shell prior to fixation.
  • The entire snail, with shell perforations, is then immersed in the fixative solution.

Main Results:
