At the moment, in our understanding of illnesses of frogs, we’re in need of all the other samples we can find. Only through the thorough study of dead and sick species of frogs will we be able to understand the complete disease picture. Therefore, every sick or dead frog can be valuable and the efforts to extract the most details from each specimen are worth the effort.

The decision of what to do with an unwell or dead frog is a complicated procedure. As of now, it is recommended that if you discover a frog suffering from illness don’t allow it to be killed in the wild. bring it home and let it be utilized. If you can, find a wildlife pathologist who is available to look at frogs and discuss the best preservation techniques.

When a frog dies its tissues begin to degenerate (post mortem degeneration). The degeneration rate is dependent on the temperature of the surrounding. If a frog dies it is essential to act quickly to obtain the highest amount of information of the specimen. Post mortem degeneration reduces the quantity of histological data and also the likelihood of identifying the source of infection.

Degeneration of the post mortem can be prevented by:

• chemicals that are referred to as fixatives (alcohol formalin, formalin, or glutaraldehyde) as well as
• freeze (though this isn’t the best option)

Preserving agents, as well as protecting tissues from post-mortem degeneration are also able to kill infective agents. Therefore, if bacteria or viruses are present after the tissue has been preserved, the infection is not able to grow. This is one of the main disadvantages preservation of specimens. The tissues that are infected are best kept in the freezer of the entire specimen or even fragments of specific tissues.

Fixatives slow down post mortem degeneration and safeguard the histology. Fixatives eliminate infective agents. Freezing helps to protect infectious agents and helps keep them alive. Toxicology can also be conducted. The freezing process stops post-mortem degeneration, however, crystals of ice damage tissues that are used for histology.

Dead frogs can be dealt with using three different methods:

• Whole frozen.
• Completely preserved in formalin or alcohol following opening the stomach.
• Necropsy is a procedure for examining grossly and removal of specific organs.

The most significant issue is that postmortem decay in dead frogs can be extremely fast; the greater the temperature, the more rapid the degeneration. The goal is to extract as many details from the frog prior to it degrading further.

If a postmortem is able to be completed immediately by someone who has experience and chemicals, then conduct post mortem. Divide organs, if possible, into two, then place specimens to be histologically examined in 10 percent buffered neutral formalin. freeze the second portion of the organs and then freeze the carcass.
