This student page has not been curated.

1. Classification

a. Higher order taxa

Domain; Phylum; Class; Order; Family; Genus Include this section if your Wiki page focuses on a specific taxon/group of organisms

2. Description and significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

• Include as many headings as are relevant to your microbe. Consider using the headings below, as they will allow readers to quickly locate specific information of major interest*

3. Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

4. Cell structure

Interesting features of cell structure. Can be combined with “metabolic processes”

5. Metabolic processes

Describe important sources of energy, electrons, and carbon (i.e. trophy) for the organism/organisms you are focusing on, as well as important molecules it/they synthesize(s).

6. Ecology

Campylobacter ureolyticus are oral and intestinal commensals of animals, which makes it hard to control infections caused by these microbes (6). Being unable to grow in number outside animal bodies, Campylobacter family serves as a sign of recent contamination with animal feces and exist widely in the environment, especially in water (7). In the river, Campylobacter species are found least in rural and fast-flowing region, while found most in regions near or downstream of sewage works (8). As an evidence of Campylobacter originated from animal feces, the number of Campylobacter increased when rainfall caused farmland water to flow into the river (8).

7. Pathology

Campylobacter ureolyticus has been identified as a gastrointestinal pathogen (4). Being a gastrointestinal pathogen, C. ureolyticus is thought to be related to inflammatory bowel diseases, including Crohn’s disease and ulcerative colitis (13). When Crohn’s disease patients were analyzed, four Campylobacter species were isolated from the patients and one of them was C. ureolyticus, indicating an existence of a relationship between Crohn’s disease and C. ureolyticus (13). Recent studies also show that its incidence in gastrointestinal related illnesses may be related to other diseases in immunocompromised patients and diabetes patients (4). Campylobacter’s major transmission pathways to humans include poultry, water, and animals (5). The prevalence of Campylobacteriosis, a general term that describes infections caused by Campylobacter genus, has increased in the entire world for past years and the research indicates that Campylobacteriosis is endemic in Africa, Asia, and the Middle East, especially in children (5). Campylobacteriosis usually accompanies symptoms of diarrhea since Campylobacter genus is a gastrointestinal pathogen (5).
