Study Notes
Pathogen Characteristics
- Gonococcal lipopolysaccharide (LPS) lacks long O-antigen side chains, distinguishing it as lipooligosaccharide (LOS).
- Associated with the formation of pores in cell surfaces through Por protein.
- Symptoms of pneumonia and meningitis can manifest as terminal complications.
Transmission and Infection
- Yersinia pestis transmission occurs when fleas feed on infected rodents, facilitating disease spread.
Campylobacter Overview
- Campylobacters are significant pathogens, causing both diarrheal and systemic diseases globally.
- Helicobacter pylori, a specific Campylobacter species, is spiral-shaped, Gram-negative, catalase and oxidase positive, and urease positive.
Diagnostic Techniques
- Molecular methods enable rapid screening for detecting infections in body fluids like CSF, plasma, serum, and blood.
- These procedures are critical for patient therapy and outbreak evaluations.
