Study Notes
Critique of Koch's Postulates
- One of the limitations of Koch's postulates is not considered a correct critique.
Consequences of Prolonged Antibiotic Use
- Prolonged use of broad-spectrum antibiotics can lead to various consequences, excluding ___________.
Normal Flora in Human Body
- Normal flora are commonly found in areas such as the skin, respiratory tract, gastrointestinal tract, and genitourinary tract.
Low Bacterial Density in Stomach
- The stomach has a relatively low density of bacteria due to its acidic environment.
Nasopharyngeal Flora
- The part of the normal microflora that occupies the nasopharynx and is often involved in opportunistic acute bacterial pneumonia in elderly and immune-compromised individuals is Streptococcus pneumoniae.
Association with African Epidemic Meningitis
- The part of the nasopharyngeal flora commonly associated with African epidemic meningitis is Neisseria meningitidis.
Benefits of Normal Microbial Flora
- The beneficial role of the normal microbial flora includes preventing colonization by pathogens, aiding in nutrient digestion and absorption, and regulating the immune system.
Normal Flora of the Colon and UTIs
- Escherichia coli (E. coli) is part of the normal flora of the colon and is also the most common cause of urinary tract infections (UTIs) in humans.
pH Regulation in the Vagina
- The adult human vagina owes its protective low pH to the presence of Lactobacillus spp.
Challenges of Normal Flora in Pathogen Identification
- One of the challenges posed by normal flora during the isolation and identification of pathogens from clinical specimens is distinguishing between pathogenic and non-pathogenic microorganisms.
