Bacteria
Spherical cells that are non-motile and lack the ability to form spores. Indigenous to normal microbiota found on skin and mucous membranes.
What are Staphylococci?
The theory that microorganisms cause disease.
What is germ theory of disease?
Offers the highest level of microbial growth control. Process of completely removing or destroying all life forms, endospores or their products on or in a substance.
What is sterilization?
Self-nourishing bacteria capable of growing in the absence of organic compounds.
What are autotrophic bacteria?
This disease is caused by a spirochete.
What is leptospirosis?
Gram-positive bacteria that virulent due to toxins and enzymes they produce. They are most common and dangerous pathogens to humans. Many species are saprophytes.
What is Streptococcu?
Recognized that carbolic acid or phenol killed microorganisms.
Who is Joseph Lister?
The destruction of pathogenic agents by chemical or physical means via application of disinfectant to an inanimate object.
What is disinfection?
Require complex organic food from a carbon source to grow and develop. Causes numerous diseases in humans.
What are heterotrophic bacteria?
Tissue gas.
What is Clostridium perfringens?
An organism that can survive only on dead or decaying organic matter.
What is a strict (obligate) saprophyte?
Accidently discovered penicillin.
Who is Alexander Fleming?
A physical method that kills microorganisms by coagulating their proteins and breaking hydrogen bonds within them.
What is dry heat?
Bacteria that grow best at high temperatures between 40C and 70C (104-158F).
What are thermophiles?
A disease that is characterized by a bull's-eye rash?
What is Lyme disease?
Spore-forming bacilli that are usually found in anaerobic infections or intoxications. Spread by either ingestion or contamination of open wounds with soil.
What is Clostridium?
What kingdom does bacteria which is prokaryotic organism belong to.
What is Monera?
A concentrated aqueous solution of formaldehyde. 37% formaldehyde gas by mass and 40% by volume.
What is formalin?
Most bacteria that cause disease in humans thrive at this pH.
What is neutral pH?
A highly resistant, rod-shaped bacterium with a high lipid content in its cell wall, which makes it resistant to desiccation and staining. Forms cavities in the lungs that provide a space for the bacteria to multiply.
What is Mycobacterium tuberculosis?
Gram-positive rods, non-spore-forming rods that cause a wide range of infections. Facultative aerobic, free-living saprophytes that can be found worldwide in fresh and saltwater, soil and air.
What are Corynebacteria?
Commonly believed that life forms could appear for nonliving matter, mostly from dead or decaying matter.
What is spontaneous generation?
Chemical disinfectants and antiseptics that damage cellular membranes and denature microbial proteins.Deactivated in the presence of soap.
What are quaternary ammonium compounds or quats?
One organism gains some benefit while the host is left unharmed.
What is commensalism?
Autoimmune disease caused by a streptococcal infection. May lead to inflammation of heart valves which can prevent them from closing properly.
What is Rheumatic fever?
