Study Notes
Bacterial Identification and Characteristics
- Lledo, RPh, is the author of the study notes.
- The Kirby-Bauer disk diffusion technique is used to test antibiotic susceptibility.
Tuberculosis (TB)
- Mantoux test is used to diagnose TB.
- Purified protein derivative (PPD) is used in the Mantoux test.
- Pulmonary Tuberculosis (PTB) affects the lungs.
- Extrapulmonary Tuberculosis (EPTB) affects other organs such as the skin, bones, and kidneys.
Syphilis
- Fluorescent Treponema test is used to diagnose syphilis.
- Hutchinson's teeth and saddle nose are symptoms of syphilis.
Vibrio cholerae
- Vibrio cholerae is a comma-shaped bacterium that causes watery diarrhea with "rice watery" stools.
- It is an aerobic, fastidious bacterium that produces an exotoxin called cholera toxin.
Legionnaire's Disease
- Legionnaire's disease is caused by Legionella pneumophila.
- It can cause Pontiac fever, which is a pneumonia-like illness.
Neisseria Meningitides
- Neisseria meningitidis is a glucose and maltose fermenter.
- It is a piliated, diplococcal bacterium that causes meningitis and meningococcemia.
- Symptoms include rashes or small dots on the skin, which can be life-threatening if sepsis occurs.
Helicobacter pylori
- Helicobacter pylori is a spiral-shaped, highly motile, microaerophilic bacterium.
- It produces large amounts of urease, which is acidic.
- It causes gastritis, gastric/duodenal ulcers, and PUD (peptic ulcer disease).
Haemophilus influenzae
- Haemophilus influenzae is a small, uniform coccobacillus that is aerobic or facultative anaerobic.
- It has six distinct antigenic types and requires growth factors X and Y.
- It causes meningitis, epiglottitis, septic arthritis, and sepsis.
Haemophilus aegyptius
- Haemophilus aegyptius is also known as Koch-Weeks bacillus or H. influenzae biotype III.
- It causes conjunctivitis and forms a pink-colored pus.
Haemophilus ducreyi
- Haemophilus ducreyi causes soft chancre, which is a sexually transmitted disease.
- It is also known as chancroid.
Pseudomonas aeruginosa
- Pseudomonas aeruginosa is a motile, obligate aerobic rod that produces pigments.
- The pigments produced are pyocyanin (blue), pyoverdin (green/yellow-green), and pyorubin (red).
- It can cause UTI, pneumonia, and other infections.
