Bio 265L - Endospores and Quadrant Streaking Techniques

These flashcards cover key vocabulary related to endospores and isolation techniques as discussed in the Bio 265L lecture by Dr. MP Di Bonaventura.

Endospores

Highly resistant dormant structures produced by certain bacterial species for survival under adverse conditions.

Bacillus megaterium

A species of bacteria often used in studies related to endospore formation.

Clostridium tetani

The bacterium responsible for tetanus, a disease characterized by muscle stiffness.

Clostridium botulinum

The bacterium that causes botulism, a rare but potentially fatal illness caused by a toxin.

Clostridium difficile

A bacterium that can cause nosocomial diarrhea and pseudomembranous colitis.

Sporangium

A cell that contains an endospore that has not yet been released.

Quadrant streaking technique

A method used for isolating bacteria from clinical specimens.

MacConkey agar

A selective-differential medium used to isolate Gram-negative enteric bacilli.

Mannitol Salt Agar (MSA)

A selective medium for isolating Staphylococcus species, which can ferment mannitol.

Blood Agar Plate (BAP)

A medium used to culture bacteria and assess their hemolytic activity.

Clinical significance of endospores

Endospores are important in various diseases and can pose risks in clinical settings.

Escherichia coli

A common bacterium found in the intestines of humans, often used in research.

Staphylococcus aureus

A bacterium capable of causing a variety of infections and is known for its ability to cause beta hemolysis.

Nosocomial infection

An infection acquired in a hospital or healthcare facility.

Bioterrorism

The intentional release of viruses, bacteria, or other germs to cause illness or death in people.
