Petri Test Lab Report

In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.

Transmission: Whooping cough is transmitted via close personal contact, uncovered sneezes and coughing from infected people. Whooping cough is also transmitted through the droplets in the air and it can develop from the upper respiratory tract (including the nose, throat and windpipe) infections. Any individuals that are close to infected people may be exposed to

“can be spread through direct contact with contaminated objects such as clothing, or through bodily fluids, but it generally not spread through the air. ” (“Smallpox facts ”)

It may be a virus or bacteria that would cause an illness. The reservoir is the place where the pathogen may adhere to live and survive. It can be a person, animal, or environmental component such as water or soil. The portal of exit is the invasion or place where the pathogen may leave the reservoir. It can be saliva, mucous membranes, feces, blood or any discharges coming out from the body. The means of transmission can be directly or indirectly transmitted. Direct transmission requires close association with the infected host, but not necessarily physical contact. Indirect contact requires a vector, such as an insect or animal. The portal of entry can be done in three ways: penetration or a cut to the skin, inhalation, or ingestion. Then it is already in the new host, which will have various factors on how the host will be affected by its severity and will also depend on the health and well being of the

The three primary ways of infectious diseases are contact, droplet, and airborne. Contact can be split into direct and indirect contact. Direct contact involves the moving of infectious agents to an impressionable person through physical contact with an infected person. Indirect contact transmission happens

The transmission of Gonorrhea is strictly direct contact, most commonly transmitted through sexual contact with an infected person. Transmission of this contagious sexual disease also includes having direct contact with infected bodily fluids. For example, a mother could pass on the infection to her newborn during childbirth. Gonorrhea is an infection of the reproductive system in either women or men. The invading pathogen enters the body through the spaces

The Materials that were used to measure the experiment where a pen and paper to record the reactions of the subjects being tested, and the subjects themselves.

A communicable disease chain is the mechanism by which an infective agent or pathogen is transmitted. The chain requires an infective agent, a source of infection, a mode of transmission and a host. An example of an infective agent could be bacteria, a virus, fungus, protozoan or helminth. The source of infective agents can be transmission from host to host, an infected human or animal, insects, soil or livestock. The mode of transmission is how the infective agent is carried from host to host. Transmission can be by air, ingestion or physical contact. To complete a life cycle or to replicate, the infective agent requires a host.

- Microorganisms from the environment through transmission from: carriers colonized at admission, admitted to wards without undergoing surveillance, isolation or eradication of the germ(s); patients who have developed the infection but who have not been isolated;contact with contaminated objects and surfaces; medical personnel, usually via their hands; invasive procedures such as the installation or maintenance of a device(1).

When a flea feeds on an infected rodent then bites a human, the disease is transmitted.

○ Can be spread from person to person by touching contaminated objects or through direct contact.

The transmission of Gonorrhea is strictly direct contact, most commonly transmitted through sexual contact with an infected person. Transmission of this contagious sexual disease also includes having direct contact with infected bodily fluids. For example, a mother could pass on the infection to her newborn during childbirth. Gonorrhea is an infection of the reproductive system in either women or men. However, it can be acquired at any point of sexual contact, including oral-pharyngeal and anal.

Indirect transmission of tuberculosis can occur by contact with contaminated inanimate objects (fomites) by susceptible persons. It can also be acquired by the ingestion of contaminated foods, (Wistreich,2010,p.25). Only people with active TB can spread the disease to others.

Transmission of the disease can occur from eye to eye via the hands and clothing etc. Flies are known to be a major carrying vector of the

Viral fever is usually transmitted via the air by droplets from diseased folks, or by touching plague-ridden secretions.
