Chapter Three Flashcards
Horizontal Transmission
Route by which a disease is transmitted directly from an infected human to a susceptible human
Infectious Diseases
Disease caused by pathogenic microorganisms
Non-communicable
Cannot be transmitted from person to person
Disinfection
Reducing risk of infection or contamination
Pseudopodia
Cell membrane extensions used for locomotion of amoeboids
Bacilli
Rod shaped bacterial cells
Mycoses
Infectious diseases caused by fungi
Spirochetes
Corkscrew shaped bacterial cells
Helminths
Parasitic worms
Gram Stain
Staining technique that permits the identification of bacteria
Binary Fissions
Process in which bacteria reproduce by splitting in half
Infestations
Infections caused by wormlike animals
Endotoxin
Potent toxin from bacteria that causes life threatening shock
Capsid
Protein coat wrapped around a virus
Latent Infection
Condition in which viruses insert themselves in a cell and do not reproduce
Isolation
Keeping an infected person in one place to prevent transmission of the disease
Spirilla
Spiral shaped bacterial cells
Mycelia
Filaments in fungi specialized for absorption of nutrients
Vibrios
Comma shaped bacterial cells
Cocci
Spherical shaped bacterial cells
Endospores
Structures produced by bacteria and formed to cope with harsh environmental conditions
Antibiotic Resistance
Bacteria adapt to antibodies making antibiotics ineffective
Pathogens
Infectious agent that causes disease
Contagious
Disease transmitted by human contact
Nucleic Acid Analogues
Antiviral Medications
Amoeboids
Type of protozoa
Flagellates
Type of protozoa that moves using whip-like appendages called flagella
Roundworms
Wormlike animal that is round in cross-section
Flatworms
Wormlike animal that has a flattened body
West Nile Virus
First discovered in Uganda, is transmitted by the Culex mosquitoes and carried by infected birds
