Microorganisms And Humans Lab Report

The title of the lab: Microorganisms and Humans – Infectious Disease Lab Resource

The aim of the lab: The aim of the lab was to see if student could detect streptococci causing bacteria in the back of their throats and other objective was to view pathogen causing diseases under the microscope.

Activity 1 – Identification of Human Streptococcal Pathogens
1. Glass microscope slides
2. Bunsen burner
3. Inoculating loop
4. Sharpie pen
5. 2 bacitracin discs
6. Sterile saline tubes
7. Sterile cotton swabs
8. Tongue depressors
9. Gloves
10. 1 blood agar plate/student pair
Divide a blood agr into two sections, one for you and the other for the lab partner. Wash hand thoroughly before proceduring to the getting a throat culture.
Depress the tongue with a sterile depressor, donot put it down on the table or touch any surface with it until the procedure is completed.
Swab the inside of the throat known as the pharynx with a sterile swab
Swab one

It includes viruses, bacterias, and fungus. A pathogen have to be present for someone to get sick. Normal microbiota are non pathogenic that live on the surface of the body or the in side of the human body. Examples of these non pathogen are bacterials that live on the and E coli for instance that is in the digestive track. These normal micobiota aid in digestion and taking up space to prevent disease causing pathogen from taking over. Transient bacterias just pass through, they donot take over an area for too long in the body. Virulent is the ability for a disease causing pathogen to produce toxins. Symbiosis on the other hand is a sharing relation=ship between organisms are different from each other. There are two other terms that come to paly when the word symbiosis is define. Commensalism is when two unlike organism have a relationship and one of them benefit, while the other is not bother, but when both benefit equally from this relation; it is called
