Pitiful Posting and the Alphabet Challenge

~~~

Lyme disease is a bacterial infection caused by the bite of a blacklegged tick carrying the bacteria Borrelia burgdoferi. The ticks pick up the disease when they bite a mouse or deer infected with B. burgdoferi. There are 3 stages of the disease:

  1. Early localized
  2. Early disseminated
  3. Late disseminated
Generally, an infected tick must be attached to a host body for 24-36 hours in order to transmit the disease. This is made easier by the fact that blacklegged ticks are extremely small. Lyme disease presents flu-like symptoms that may include:
  • Body-wide itching
  • Chills
  • Fever
  • General ill-feeling
  • Headache
  • Light-headedness or fainting
  • Muscle pain
  • Stiff neck
There may also be a bullseye rash at the site of the bite. Untreated, the disease can spread to the joints, heart and brain. Blood tests can be used to determine the presence of Lyme which can be treated with antibiotics. In later stages of the disease, I have seen pets come in to the vet hospital in such intense joint pain that they couldn’t bear to be touched.

According to the MedlinePlus Medical Encyclopedia (associated with NIH)

an antibody (also known as an immunoglobulin) is a protein produced by the body’s immune system when it detects harmful substances, called antigens.

Each antibody responds to and binds to a particular antigen. They are in the shape of a Y comprised of 4 polypeptides; 2 heavy chains and 2 light chains. Antibodies are produced by B-cells, a type of lymphocyte.

When healthy tissue is mistaken for something harmful and antibodies are produced an autoimmune disease can develop.

Pitiful Posting and the Alphabet Challenge

One of the great things about WordPress is the little calendar that shows you the days on which you’ve posted. One of the bad things about it is looking at that same calendar and seeing how sad and empty it looks. -_- To get myself back into the swing of posting, I’ve decided to start an Alphabet challenge. Hopefully I can kick-start myself into a blogging groove again with this. Below I’ll list each day, the letter, and as I pick my topic, I’ll come back here and add it. The one day that I probably won’t post on is June 8th. Blasted GRE. If I absolutely cannot find an animal or drug or something that follows the days letter, I’ll get creative.
