Question

A gram-positive bacteria has entered through a cut. Describe IN DETAIL how an inflammatory response would work against this bacteria.

Answer 1

When Gram positive bacteria entered through the cut, inflammatory response (inflammation) occurs when tissues are injured by this bacteria, trauma, toxins, heat, or any other cause as a result of the invasion.The damaged cells release chemicals including histamine, bradykinin, and prostaglandins. These chemicals cause blood vessels to leak fluid into the tissues, causing swelling.The body reacts to disease-causing bacteria by increasing local blood flow (inflammation) and sending in cells from the immune system to attack and destroy the bacteria. Antibodies produced by the immune system attach to the bacteria and help in their destruction.

At the tissue level, inflammation is characterized by redness, swelling, heat, pain, and loss of tissue function, which result from local immune, vascular and inflammatory cell responses to infection or injury. Important microcirculatory events that occur during the inflammatory process include vascular permeability changes, leukocyte recruitment and accumulation, and inflammatory mediator release.
