With the current rise in tick counts across the midwest, tick-borne diseases should be of significant interest and concern for both human and animal health (1). Across the tick species, different diseases can be caused by various microbes and many of them can be quite harmful to the host. According to the CDC, a list of the most common tick-borne diseases includes the following: Lyme disease, Anaplasmosis, and Babesiosis, each of them being transmitted through the saliva during a bite from an infected tick (5). Lyme disease, an infection caused by the bacterium Borrelia burgdorferi, as well as Anaplasma phagocytophilum, the pathogen known to cause Anaplasmosis, are carried both by the common blacklegged tick (Ixodes scapularis) and the western blacklegged tick (Ixodes pacificus). In addition to B. burgdorferi and A. phagocytophilum, the blacklegged tick also carries the pathogen Babesia microti, which causes the disease, Babesiosis (4). Although these three vector-borne diseases are brought on and carried by ticks, each of them function differently. Based on their structure, genome, and phylogeny, we have a better understanding of how these pathogenic microbes infect their hosts, as well as how they survive and reproduce, causing the symptoms that we associate with each disease.
At right is a sample image insertion. It works for any image uploaded anywhere to MicrobeWiki.
The insertion code consists of:
Double brackets: [[

Legend/credit: Electron micrograph of the Ebola Zaire virus. This was the first photo ever taken of the virus, on 10/13/1976. By Dr. F.A. Murphy, now at U.C. Davis, then at the CDC. Every image requires a link to the source.
Closed double brackets: ]]
Other examples:

A citation code consists of a hyperlinked reference within "ref" begin and end codes.
To repeat the citation for other statements, the reference needs to have a names: "<ref name=aa>"
The repeated citation works like this, with a forward slash.[1]
Structure
Include some current research, with at least one figure showing data.
Every point of information REQUIRES CITATION using the citation tool shown above.
Genome
Include some current research, with at least one figure showing data.
Phylogeny
Include some current research, with at least one figure showing data.
Symptoms
Treatment
