Microorganisms That Cause Infectious Disease
Introduction: Diseases can be communicable or non-communicable. Communicable diseases are caused by infectious microorganisms which are pathogens.
The aim of this passage is to discuss various types of microorganisms that cause disease. Microorganisms are simple organisms that are unicellular or live in colonies. The group contains bacteria, virus, algae, fungi, protozoa. They can be divided into pathogenic and non-pathogenic. In this passage pathogenic microorganisms that cause diseases are concerned. A disease is an abnormal condition affecting the body of an organism. Some of them called infectious diseases such as common cold, influenza, etc.

Pathogenic microorganisms:
SARS coronavirus
SARS coronavirus is an air-borne virus causes a respiratory disease in humans called Severe Acute Respiratory Syndrome (SARS). It transmits by riding on dust particles or small respiratory droplets and staying suspended in air and travel distances on air currents. SARS coronavirus is large, pleomorphic and spherical shape and consist of a single stranded of RNA. On the surface, it has bulbous surface projections. Its lipid envelop appears to consist of a distinct pair of electron dense shells. In order to infect a host, its replication takes place in the cytoplasm in a membrane-protected microenvironment. It incorporates the viral genetic materials into the host’s cells. Translation of the genome then takes place to produce the viral replicase. Viral replicase catalyzes that replication to produce new viral particles which move on to infect other cells. Different coronaviruses cause different transcription and translation patterns in the host.
The symptoms of SARS include fever of 38 °C, Myalgia, lethargy, gastrointestinal symptoms, cough, sore throat, etc.
Vibrio cholerae
Vibrio cholerae is a water borne bacteria causes Cholera and transmits by being carried in water or contaminated food such as shellfish and plankton to get into human bodies.
Vibrio

    The incubation period for the SARS virus is 2 to 10 days. " It seems to spread by close person-to-person contact. The coronavirus that causes SARS is thought to be transmitted by respiratory droplets produced when an infected person coughs or sneezes. Droplet spread on cars when droplets from the cough or sneeze of an infected person are propelled a short distance [typicality up to 3 feet) through the air and deposited on the mucous membranes of the mouth, nose, or eyes of a person is nearby. The virus can also spread when a person touches the surface or object contaminated with infectious droplets and then touches his mouth, nose, or eyes" ( Centers for Disease Control and Prevention). The SARS virion attaches to a receptor on the host cell membrane and releases enzymes that weaken then membrane and enables the SARS virus to penetrate the cell. The SARS virus removes the protein coating that protects its genetic materials, multiplies and the infection spreads to the help the cells of the host. The symptoms of a SARS infection usually starts with elevated temperature…

    SARS

    SARS is a virus that affects the respiratory system. SARS stands for severe acute respiratory syndrome. It is a severe form of pneumonia. This virus was first discovered in February of 2003 by a physician named Dr. Carl Urbani. During that year, 8,098 people became infected with the virus. Of this number, 774 people died. Tracing SARS back to its origin was tedious and time consuming for scientists. It is believed that the virus began in Guangdong province, China (CDC, 2011, p. xx). This is an area located near the Pearl River delta region of southern China which is a major manufacturing and export territory. Large amounts of people and goods pass through here and nearby Hong Kong. The issue with this area, scientists discovered, is that agriculture and industry is practiced much too close together. Chickens, pigs, ducks, and fish are all farmed together by villagers using traditional techniques. It is these techniques that provide unique opportunities for new and deadly strains of viruses and bacteria to transfer between species.…
