Immunity
Terminology
Diseases
100
This kind of virus only attacks bacteria cells
What is BACTERIOPHAGE
100
This type of Bacteria requires a constant supply of oxygen
What is an Obligate Aerobes
100
These cells work independently and directly destroy antigens and pathogens
What are Killer T - cells
100
A group of organisms that lack a cell nucleus, or any other membrane-bound organelles
What are Prokaryotes
100
This contagious respiratory infection was first described on Feb. 26, 2003. This virus that has killed almost 700 people worldwide jumped to humans from civet cats, which are considered a delicacy by many people in southern China.
What is SARA
200
The latent form of a bacteriophage in which the viral genes are incorporated into the bacterial chromosomes without causing disruption of the bacterial cell
What is PROPHAGE
200
This is the process by which a 'male' bacteria cell passes DNA to a 'female' bacteria cell via a sex pilus.
What is Bacterial Conjugation
200
B cells will divide into these antibody producing cells
What are Plasma B Cells
200
Bacteria appear purple when stained, have a thick layer of carbohydrate and protein surrounding cell membrane.
What are Gram Positive Bacteria
200
This viral infection affects mainly the nose, throat, bronchi and, occasionally, lungs. It is transmitted easily from person to person via droplets and small particles produced when infected people cough or sneeze. In 1918, the outbreak of this virus killed more people than the Great War, known today as World War I (WWI).
What is Influenza
300
A retrovirus will contain this as its genetic material
What is RNA
300
This is a dormant, tough, and temporarily non-reproductive structure produced by certain bacteria.
What is an Endospore
300
This is the name of the chemical messenger that initiates the inflammatory response after a tissue is damaged
What is Histamine
300
An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.
What is a Heterotroph
300
Although researchers have traced the origins of this virus as far back as the 1930s, the first diagnosis was not made until 1981. The origin of this virus has been found in wild chimpanzees living in southern Cameroon. At the end of 2008 there were an estimated 65,000 people in Canada living with this virus
What is HIV
400
This event occurs during a retrovirus life cycle, often causing the virus to mutate
What is REVERSE TRANSCRIPTION
400
This is the process that produces energy without the use of oxygen
What is Fermentation
400
This enzyme found in egg white, tears, and other secretions is responsible for breaking down the walls of many kinds of bacteria and thus it provides some protection against infection.
What is Lysozyme
400
Bacteria that can survive with or without oxygen
What is a Faculative Anaerobe
400
This disease emerged out of the filthy water and living conditions of Calcutta India in the early 1800. It is an acute infectious disease which results in a painless, watery diarrhea in humans.
What is Cholera
500
During this stage of the lytic cycle, viral components are produced
What is Replication or Biosynthesis
500
Asexual reproduction by a separation of the body into two new bodies.
What is Binary Fission
500
Viruses can be identified by these protein structures that are found on their surfaces.
What are Antigens
500
An entire virus particle, consisting of an outer protein shell called a capsid and an inner core of nucleic acid (either RNA or DNA).
What is a Virion
500
This is a disease caused by a bacterial infection. It can affect many parts of your body, but is found most commonly (80% of the time) in the lungs. More than 2000 years ago in ancient Greece, Hippocrates called this disease "phthisis".
What is Tuberculosis
