Question
Research Paper Discussed three infectious diseases. The first one on gram negative bacteria, the second one on gram positive bacteria, and the third one on eukaryotic parasitic diseases. The followings should be included in the paper: name of microorganism, diseases caused, definition, etiology, pathophysiology, symptoms/ signs, diagnosis, methods of identification of the microorganisms, treatments, complications, prognosis and prevention. In the reference section, a minimum of 10 sources is required, three of these sources should be published papers, one for each subjectThe reference can be written in any format.Explanation / Answer
ANS-
The disease caused by Gram negative , gram positive and eukaryotic parasites
are various types based upon the infectious agent.
The Gram stain test, developed in the 1800s by Hans Christian Gram, is a method for classifying different types of bacteria using a chemical stain and viewing through a microscope the results on the bacteria’s protective cell wall.
Most bacteria are classified into two groups—Gram-positive or Gram-negative—depending on whether they retain a specific stain color. Gram-positive bacteria retain a purple-colored stain, while Gram-negative bacteria appear pinkish or red.
The gram negative bacteria , Pseudomonas aeruginosa, which causes bloodstream infections and pneumonia in hospitalized patients. It is a common cause of pneumonia in patients with cystic fibrosis.
Staphylococci are gram-positive aerobic organisms. Staphylococcus aureus is the most pathogenic; it typically causes skin infections and sometimes pneumonia. A member of the normal flora of the body, frequently found in the nose, respiratory tract, and on the skin.
S. aureus usually acts as a commensal bacterium, asymptomatically colonizing about 30% of the human population, it can sometimes cause disease.[5] In particular, S. aureus is one of the most common causes of bacteremia and infective endocarditis. Additionally, it can cause various skin and soft tissue infections,[5] particularly when skin or mucosal barriershave been breached.
S. aureus infections can spread through contact with pus from an infected wound, skin-to-skin contact with an infected person, and contact with objects used by an infected person such as towels, sheets, clothing, or athletic equipment..
A parasitic disease, also known as parasitosis, is an infectious disease caused or transmitted by a parasite. Many parasites do not cause diseases. Parasitic diseases can affect practically all living organisms, including plants and mammals..
When they do, symptoms include the following:
Gram negative baceria, Vibrio cholerae—the bacteria responsible for cholera—is a waterborne pathogen.,
natural habitat is brackish or saltwater.
During infection, V. cholerae secretes cholera toxin, a protein that causes profuse, watery diarrhea .
Cholera infections are most commonly acquired from drinking water in which V. cholerae is found naturally or into which it has been introduced from the feces of an infected person. Other common vehicles include contaminated fish and shellfish, produce, or leftover cooked grains that have not been properly reheated. Transmission from person to person, even to health care workers during epidemics.
When visiting areas with epidemic cholera, the following precautions should be observed: drink and use bottled water; frequently wash hands with soap and safe water; use chemical toilets or bury feces if no restroom is available; do not defecate in any body of water and cook food thoroughly.
