Chapter 17 - Overview of Human Infectious Diseases (DISEASES AND SPECIES) Flashcards
Dermatitis
Inflammation of the skin
Folliculitis
Inflammation of a hair follicle
Stye
Inflammation of a sebaceous gland that opens into a follicle of an eyelash
Furuncle
Pus producing infection of the skin, usually from folliculitis
Carbuncle
Pus producing infection from a group of furuncles
Macule
Surface lesion that is neither raised or depressed, it is like measles
Papule
A surface lesion that is raised and firm, like chicken pox
Vesicle
A small, fluid-filled sac, like chicken pox or shingles
Pustule
A pus-filled surface lesion
Otitis media
Infection of the middle ear. Usually empirically treated
Otitis externa
Infection of the outer ear (ex: swimmer’s ear)
Conjunctivitis
Inflammation or infection of the conjunctiva
Keratitis
Inflammation or infection or the cornea
Keratoconjunctivitis
Both cornea and conjunctiva are inflamed
URT (type of infection)
Upper respiratory tract
LRT (type of infection)
Lower respiratory tract. Infections of this are the most common cause of death from infectious diseases
Bronchitis
Inflammation of the mucous membranes lining the bronchial tubes
Bronchopneumonia
Bronchitis and pneumonia
Epiglottitis
Inflammation of the epiglottis (Hib - Haemophilus influenza b)
Laryngitis
Inflammation of the mucous membrane of the larynx
Pharyngitis
Inflammation of the mucous membrane and underlying tissue of the pharynx. Most cases are viral. If it is strep, Streptococcus pyogenes
Pneumonia
Inflammation of one or both lungs. Usually caused by bacteria, but can be caused by fungi, protozoa, or viruses
Sinusitis
Inflammation of one or more sinuses. The most common causes are Streptococcus pneumoniae and H. influenzae
Colitis
Inflammation of the colon
Diarrhea
An abnormally frequent discharge of semi-solid or fluid fecal matter
Dysentery
Frequent watery stools, fever, abdominal pain, and dehydration
Enteritis
Inflammation of the intestines - usually small intestine
Gastritis
Inflammation of the mucosal linings of the stomach
Gastroenteritis
Inflammation of the mucosal linings of the stomach and intestines
Hepatitis
Inflammation of the liver caused by a virus
Upper UTIs
Kidneys - nephritis or pyelonephritis and ureteritis
Lower UTIs
Bladder (cystitis), urethra (urethritis), or the prostate in men (prostatitis)
Cystitis
Inflammation of the bladder. Most common type of UTI caused by E. coli
Nephritis
Usually preceded by cystitis
Ureteritis
Inflammation of one or more ureters. Usually caused by the spreading of infection upward from the bladder or downward from the kidneys
Urethritis
Inflammation of the urethra. Usually sexually transmitted. Most commonly caused by Chlamydia trachomatous
Prostatitis
Inflammation of the prostate gland. NOT an infectious disease
Endocarditis
Inflammation of the endocardium, the endothelial membrane that lines the cavities of the heart
Myocarditis
Inflammation of the muscular walls of the heart
Pericarditis
Inflammation of the pericardium - the membranous sac around the heart
Bacteremia
Presence of bacteria in the bloodstream
Transient bacteremia
Temporary presence of bacteria in the blood – can be from dental extractions, can be from damage to the intestinal, respiratory, or reproductive tract
Septicemia
SERIOUS. The presence of pathogens or toxins in the blood
Encephalitis
Brain inflammation
Encephalomyelitis
Inflammation of the brain and spinal cord
Meningitis
Inflammation of the membranes that surround the brain and spinal cord (meninges)
Meningoencephalitis
Inflammation of the brain and membranes that surround the brain and spinal cord (meninges)
Myelitis
Inflammation of the spinal cord
