Study Notes
Innate Immunity
- Innate immunity is non-specific, meaning it doesn't target specific pathogens.
- The cellular immune response is mediated by T-cells, which play a crucial role in fighting infections.
- The unbroken skin is the first line of body defense, providing a physical barrier against pathogens.
- A successful pathogen doesn't kill its host before it is transmitted, allowing the pathogen to spread to new hosts.
- Ribosomes are unlikely to contain useful antigens for identification of bacteria by serologic tests.
Gram Staining
- Mycoplasma pneumoniae is not visible in the Gram's stain because it does not have a cell wall, making it an exception to the Gram stain.
- The coagulase test is used to differentiate Staphylococcus aureus from Staphylococcus epidermidis, two types of bacteria that can be difficult to distinguish.
- In passive diffusion, solute molecules cross the membrane as a result of various factors, including concentration gradients, temperature, and particle size.
Genetic Transfer
- Transfer of DNA from a donor to a recipient cell can occur through a bacteriophage.
Transformation
- Transfer of DNA from a donor to a recipient can occur as naked DNA in solution.
Krebs Cycle
- The Krebs cycle is a series of chemical reactions in which ATP is produced from the oxidation of acid.
- It involves the oxidation of pyruvic acid.
- NADH is produced from the oxidation of acid during the Krebs cycle.
