Study Notes
Associated Gram-Negative Rods and Cocci
-
Haemophilus influenzae
- Linked to fever, sore throat, and swelling of the neck due to epiglottitis.
-
Escherichia coli (E. coli)
- Common cause of urinary tract infections (UTIs) presenting with dysuria, oliguria, and may lead to diarrhea.
-
Salmonella enterica
- Associated with gastroenteritis characterized by fever, cramps, and altered bowel movements.
-
Salmonella typhi
- Causes typhoid fever with symptoms including cramps and altered defecation; requires T-cell immunity for survival within cells.
-
Neisseria meningitidis
- Gram-negative cocci linked to nuchal rigidity, petechiae, and can lead to septic shock.
-
Bacteroides fragilis
- Associated with intra-abdominal abscesses, presenting with abdominal pain and fever.
-
Vibrio cholerae
- Causes severe watery diarrhea known as 'rice water' diarrhea.
-
Campylobacter jejuni
- Curved rod linked to gastroenteritis, resulting in pain, fever, and diarrhea.
-
Neisseria gonorrhoeae
- Diplococci associated with urethritis and skin rash, often transmitted through sexual contact.
-
Neisseria meningitidis (repeated)
- Also linked to nuchal rigidity, petechiae, and septic shock, confirming its role in severe infections.
