PATHOLOGY

Detailed explanation-1: -Infection: Is an invasion of the body tissue by pathogenic microorganism. As a direct care staff person, an important part of your job is to protect yourself and the clients from infectious disease(s). Some clients have weakened immune systems and are more vulnerable to getting infections.

Detailed explanation-2: -Necrosis is the medical term for the death of your body tissue. When the cells in your tissues die, it can affect many different areas of your body, including your bones, skin and organs. Necrosis can occur because of illness, infection, injury, disease or lack of blood flow to your tissues.

Detailed explanation-3: -The bacteria resist the immune response by releasing toxins called leukocidins. As the neutrophils die off from toxins and old age, they are destroyed by macrophages, forming the viscous pus. Bacteria that cause pus are called pyogenic.

Detailed explanation-4: -Pathogens can produce enzymes that disrupt normal tissue and allow for further invasion into the tissues. Pathogens can produce toxins that interfere with protein function deemed necessary by the host cell for proper maintenance.
