Is bacterium is the pathogen for polio?

Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person.

Are bacteria pathogens?

Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions. Pathogens of all classes must have mechanisms for entering their host and for evading immediate destruction by the host immune system. Most bacteria are not pathogenic.

What type of germ causes polio?

Polio, or poliomyelitis, is a disabling and life-threatening disease caused by poliovirus. The virus spreads from person to person and can invade an infected person’s spinal cord, causing paralysis (can’t move parts of the body).

What is a true pathogen?

A true pathogen is an infectious agent that causes disease in virtually any susceptible host. Opportunistic pathogens are potentially infectious agents that rarely cause disease in individuals with healthy immune systems.

Is polio a retrovirus?

Poliovirus, the causative agent of polio (also known as poliomyelitis), is a serotype of the species Enterovirus C, in the family of Picornaviridae. Poliovirus is composed of an RNA genome and a protein capsid….

Is polio a icosahedral?

Poliovirus is a member of the family of picornavirus. Picornaviruses are small, about 300 angstroms in diameter, and are comprised of an icosahedral protein coat and a single-stranded positive sense RNA genome. Poliovirus infection occurs by the fecal-oral route.

What are microbial pathogens?

Type of microbe A pathogen is a micro-organism that has the potential to cause disease. An infection is the invasion and multiplication of pathogenic microbes in an individual or population. Disease is when the infection causes damage to the individual’s vital functions or systems.

What are pathogenic bacteria examples?

These pathogens can cause pneumonia or urinary tract infection and may be involved in coronary heart disease. Other groups of intracellular bacterial pathogens include Salmonella, Neisseria, Brucella, Mycobacterium, Nocardia, Listeria, Francisella, Legionella, and Yersinia pestis.

What type of pathogen is polio?

Polio, or poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus. The virus spreads from person to person and can infect a person’s spinal cord, causing paralysis (can’t move parts of the body).

Is polio A virus bacteria or fungi?

Polio is a viral infection that can cause paralysis and death in its most severe forms. It can spread easily from person to person.

What are examples of true pathogens?

Examples of pathogens include: bacteria. viruses. fungi….These include:

• cholera.
• diphtheria.
• dysentery.
• bubonic plague.
• tuberculosis.
• typhoid.
• typhus.

Are pathogens organisms?

What is a pathogen? A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.
