Why are we more vigilant about zoonotic diseases for the gametogenesis lab?

Let's add the missing piece of information:

In this part of the lab we'll be taking some reasonable precautions to make sure that we don't allow undue contact between cat/dog parasites and the interior of our bodies.

Why are we more vigilant about zoonotic diseases for the Gametogenesis lab?

[Please remember to wash your hands!]

- The samples are fresh (they were very recently a part of a living organism.)

- The samples are from warm-blooded animals which have similar diseases to ours

- The samples are from mammals, so their parasites are closer evolved to us

- We are using sharp tools and razor blades, making access into our bloodstream potentially easier

All answers indicates the need for necessary precautions in the course of the experiment.

Explanation:

A zoonosis (plural zoonoses, or zoonotic diseases) is an infectious disease which originated from bacteria, viruses, or parasites that moves from non-human animals (mainly vertebrates) to humans. Major contemporary diseases like Ebola virus disease and salmonellosis are zoonoses.

Zoonoses have varying forms of transmission. In direct zoonosis the disease is mainly transmitted from other animals to humans via media e.g. air (influenza) or via bites and saliva (rabies).

Transmission could also be through an intermediate species (known as a vector), that serve as host for the disease pathogen as it is not affected by the diseases presence.

The need to be vigilant in the course of the lab experiment to avoid infection and transmission from one Hunan to another.

Diseases which are spread from animals( higher animals )other than man  to  human  being are called zoonosis. They are caused by bacteria, viruses,  fungi and parasites in theses animals, and through bites, domestication, droplets contacts, farming, and hunting are passed to human. Some are also transmitted as vectors.

Statistically, they  represented  61%  of  thousands of pathogens known to have infected human.

Answers.

Therefore during process of Gametogeneis and other experiemntal procedures in the laboratory,  a lot of vigilance is needed because,

→In most cases to guarantee the experimental success, they are needed fresh to be used in the laboratory, thus careful measures not to have contact with the possible infected fluid and blood of these animals  is needed.

→Human shared the almost same  physiological make up with these animals, thus it is easy for human to also serve as host for the same pathogens that they harbour, thus during lab.preparations necessary protection to guide against these  should be taken

→Experimental procedures may involved laceration, and which involved blood spillage and contacts.Therefore necessary measures is needed to avoid unnecessary cuts which may lead to infections transmission and possible  contamination.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
