Study Notes
Key Species and Characteristics
- Campylobacter jejuni is the most prominent species within the genus Campylobacter.
- Campylobacters are characterized morphologically as spiral-shaped or curved rods.
Growth and Environment
- Optimal growth conditions for Campylobacters are at temperatures around 42°C, resembling avian body temperature.
- They prefer microaerophilic conditions, with an oxygen concentration of about 5-10%.
Transmission and Infection
- Campylobacteriosis is primarily caused by the ingestion of contaminated food, particularly undercooked poultry.
- Common transmission routes include consumption of contaminated water or unpasteurized dairy products.
- Campylobacter infection typically presents as gastroenteritis with symptoms such as diarrhea, abdominal pain, fever, and nausea.
Clinical Presentation
- Infection with Campylobacter jejuni can lead to severe diarrhea, which may be bloody, and abdominal cramps.
- The illness often resolves within a week but can lead to complications in some cases.
