Pyogenic Infections Flashcards
Pyogenic infections are
Puss-forming infections.
Pyogenic Bacteria
Staphylococcus PIA P=Pneumococcus I=Influenza A = Anthrax
Pyogenic infections are caused by _____ (+/-) bacteria.
Positive
Staph causes ____________ infections.
Pyogenic
Two types of staph that cause pyogenic infections.
S. aureus and S. epidermidis
Furuncle
A pus and poly-filled area caused by folliculitis.
Carbuncle
A group of pus-filled bumps forming a connected area of infection under the skin.
Common area for carbuncles.
Neck
Osteomyelitis
Inflammation of the bone.
Bacteria that can cause osteomyelitis and how.
Staph aureus. It binds to receptors on the bone matrix and degrades the bone.
What part of the bone does osteomyelitis occur?
The metaphysis
Newly formed bone.
Involucrum
Dead bone
Sequestrum
Why does pyogenic myelitis begin at the metaphysis?
Because it has a rich blood supply.
Osteomyelitis detection.
Do a bone scan and look for hot spots where radionuclides locate.
Show up on a bone scan 1-2 weeks later.
What can pyogenic osteomyelitis cause?
Acute suppurative arthritis.
Bacteria that causes food poisoning.
Staph.
What is strep disease?
A Group A beta-hemolytic disease.
Weapons of strep.
Streptokinase and streptolysin.
Streptokinase
Breaks down blood clots and tissue.
Streptolysin
Breaks down white blood cells.
Area affected by strep.
Oropharynx.
Complications of strep throat.
Tonsillitis, quinsy, and Ludgwig’s angina.
Quinsy.
A complication of tonsillitis in which the infection spreads behind the tonsils.
Ludwig’s angina.
A complication of strep in which the floor of the mouth becomes infected.
Strep throat is AKA.
Pharyngitis
Quinsy is AKA
A peritonsillar abscess.
Scarlet fever occurs in some people who have what?
Strep throat.
Clinical signs of strep throat.
Rash (circumoral palor)
Strawberry tongue
Strep throat
Infections that spread include…
Cellulitis
Phlegmon
Necrotizing fasciitis
Spread in loose tissues.
Cellulitis.
Spread in tissue planes within a muscle.
Phlegmon.
Characteristics of cellulitis.
Erythema, swelling, and tissue necrosis.
How does Diphtheria work?
Blocks protein synthesis, and the cells die.
Where in the body do you see diptheria?
Around the tonsils.
How are meningococcal infections spread?
The bacteria are in the nose and throat (nasopharynx).
Waterhouse-Friderichson Syndrome
Skin and adrenal hemorrhages
Acute meningitis.
Disseminated intravascular coagulation (DIC) - microhemorrhages
How do you get gonococcal infections?
They’re sexually transmitted (venereal).
Cells affected by gonococcal infections.
Nonsquamous cells.
What do gonococcal infections cause?
1) Urethritis
2) Purulent discharge
3) Tubular scarring
Pelvic Inflammatory Disease (PID)
Caused by bacteria traveling up the fallopian tubes and sometimes to the ovaries.
Salpingitis
Inflammation of the fallopian tubes.
When can you get PID?
If you have an untreated STD.
