Lyme Disease and Its Effects on The Body with a Focus On The Immune System. Lyme disease is an infection of the bacteria Borrelia burgdorferi. It can be contracted by a bite from ticks‚ along with many other vector-borne diseases. It can affect all systems in the body and can cause significant damage to the nervous system. The disease can be cured through antibiotics‚ but many times it goes unnoticed until it has already done damage. It has a wide range of symptoms because it effects all systems

Name Period Chapter 54: Community Ecology Concept 54.1 Community interactions are classified by whether they help‚ harm‚ or have no effect on the species involved. 1. What is a community? List six organisms that would be found in your schoolyard community. 2. This section will look at interspecific interactions. Be clear on the meaning of the prefix! To begin‚ distinguish between intraspecific competition and interspecific competition. Give an example of each. Type of Competition

response after pathogen challenge at this site [50]. These multiple roles include thickening of the epithelial cell layer‚ production of mucins and the constitutive and induced expression of a wide range of antimicrobial mediators including the epithelial defensins‚ secretory leucocyte protease inhibitor (SLPI) and cathelicidins [51–53]. The detection of invading microbes occurs through the recognition of a highly conserved structure present on the outer membrane of the bacteria (Pathogen associated

Cardio Vascular System The Heart The heartis a muscular pumping organ located medial to the lungs along the body’s midline in the thoracic region. The bottom tip of the heart‚ known as its apex‚ is turned to the left‚ so that about 2/3 of the heart is located on the body’s left side with the other 1/3 on right. The top of the heart‚ known as the heart’s base‚ connects to the great blood vessels of the body: theaorta‚ vena cava‚ pulmonary trunk‚ and pulmonary veins. Circulatory Loops There are

The honey bee is a subset of bees in the genus Apis‚ it is black and yellow in colour and is no longer than an inch in size. They are distinguished by the production and the storage of honey and construction of perennial‚ colonial hives out of wax. The insect’s habitat is mainly meadows‚ woods and gardens; the bee usually makes its nest in hollow trees. The habitats are advantageous for the bees due to the growth of flowering plants in that area. Figure 1 The Honeybee seems to have originated in

Susceptibility: the lack of resistance to injury‚ foreign proteins and invading pathogens Innate immunity includes external physical and chemical barriers (skin and mucous membranes) and various internal defenses (phagocytes‚ natural killer cells‚ antimicrobial proteins); It does not involve specific recognition of a microbe

Proteus mirabilis The genus Proteus‚ according to Bergey’s Manual of Determinative Bacteriology‚ is a group of straight rod Gram negative bacteria around 0.4-0.8 μm in diameter and 1-3 μm in length. In the microscopic test done‚ it was seen that the unknown culture contained rods that are on the shorter side‚ thus was identified as bacteria that appear to be coccobacilli. Because of the presence of peritrichous flagella‚ species included this genus are motile and most strains swarm in periodic cycles
