Background:
Despite being a significant element of biodiversity and playing an important role in their hosts' physiology, ecology and evolution, parasites remain understudied and are often neglected during biotic surveys and other collection efforts. More often than not, it is due to the perception that parasitological examination requires specialized expertise and substantial additional time to perform.
Results:
Herein, we provide an express method for recovery and fixation of endoparasites from the gastrointestinal tract of small mammals that can be used by both parasitologists and vertebrate biologists in either field or laboratory conditions. The method does not require special training beyond minimal practice and does not need optics or other special equipment.
Discussion:
Our goal is to encourage collection of endoparasites as part of biotic surveys by vertebrate biologists to provide valuable additional biodiversity information in cases when a traditional complete parasitological examination of hosts is not feasible. We believe that this technique will also be useful for professional parasitologists.

Here's a detailed walkthrough of this complex system:
Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Histology of the Gastrointestinal (GI) Tract
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...
