Micro Biology Test 4

DiseaseKey Word
Carbuncle Very easy to transmit
Scalded Skin Syndrome Caused by 2 exotoxins called exfoliants
Pyoderma/Impedigo Not just direct contact, fomites moist towels or objects
Acne Propionibacterium acnes and others
Burn infections Caused by Pseudomonas aeruginosa, blood flow is missing thus, no WBC (phagocytes) are available to help fight the infection
Urinary Tract Infection (UTI) Moves from urethral opening up the the urethra to the bladder
Lyme Disease Borrelia burgdoferi, a spirochete, gram variable, may stain as a Gram negative
Rubella/German Measles Especially Serious during the 1st 8 weeks of pregnancy
Rubeola/Measles Koplik's spots: White spots with central bluish cheeks, appear on the upper lip and cheek mucosa 2-3 days before other symptoms appear
Varicella/Chicken Pox Release of this virus causes fever and malaise, Lesions appear in cyclic crops every 2-4 days that are synonymous with viral replication,
Varicella/Shingles Can be seen in infants and children, usually occur unilaterally on one side of the trunk like a girdle, a person who has not had chicken pox (or vaccine) can get shingles from shingles lesions
Mumps Can cause sterility but rare, can replicate in other glands and organs (other than the respiratory tract) like the testes and meninges, part of MMR vaccine
Herpes Simplex Skin Infection Recurrence is always in the same place as the initial infection
Genital Warts Common in the U.S
Cytomegalovirus In severe in neonatal infections (about 4000 cases per year in U.S) growth retardation, brain damage, liver damage, hearing loss, and death in about 30% of cases
Gonorrhea 40% of males and 60-80% of females are asymptomatic and can act as carriers for 5-15 years, infection of the lymphatics of the pelvic area, NO penicillin
Syphilis Organisms multiply and spread throughout body, in Teritary stage, symptoms are due to formation of granulomatous inflammations called GUMMAS
Nongonococcal Urethritis Chlamydia tractomatis (Some my Mycoplasma)
Trichtomonas Only infects the vagina when vaginal pH is abnormal, signs/symptoms: copious, white, fowl-smelling discharge, especially in female having consistency of raw egg white
Lesionaires Disease Death is usually due to shock and kidney failure, linked to water, enters patient via aerosols breathed into lungs
Tuberculosis Most active cases of TB disease result from Reactivating old infection (most), or have AIDS (which may also be reactivated)
Bacterial Meningitis Main causes of meningitis broken down by age group
Influenza With surface antigens on spikes called Hemagglutinin is responsible for infectivity, it attached to receptor sites on the RBS's and other host cels Some also have neuraminidase spikes, an enzymes that helps the virus penetrate the mucus layer protecting the respiratory epithelium and get out of infected cells
Antigenic Variation Changeability that occurs by antigenic drift and antigenic shift
Pharyngitis (Sore throat) Usually caused by a virus 90%, roughly 10% of cases are bacterial, 95% of those bacterial cases are caused by Strep. pyogenes
Strep Throat No cough, no nasal discharge, helps distinguish it from the common cold where there IS both of these
Glomerulonephritis Involves damage to the kidneys
Laryngitis & Epiglottitis Was almost always caused by H. influenza but Hib vaccine took care of that and lowered it, now its caused by viruses, children between ages of 2 and 6 are more susceptible
Bronchitis Risk to infants, the young children, and the elderly, characterized by shortness of breath, wheezing Diagnosis is from sputum clustered, acute bronchitis doesn't need antibiotics, infection would clear within a week
Diphtheria Bacteria must be infected with a particular phage in lysogenic state Has a fuzzy membrane called a pseudomembrane covering throat and tonsils
Middle ear infection Acute Otitis Media (AOM), caused by Strep Pnemoniae, h. influenza, strep. progenies is sequel, Children learning to talk at this time at risk of poor language development, when bacterial/viral germs cause colds or sore throats that spread to middle ear
Common cold MOST COMMON COMMUNICABLE DISEASE Cough and nasal discharge, spread by fomites more often than aerosols
Strider Barking cough
Croup Acute airway obstruction
Whooping Cough the "whoop" is rare in infants under 6 months and adults
Pneumonia Common pneumonia-causing bacteria in adults in strep. pneumoniae, school-age kids mycoplasma pneumonia is causative agent Respiratory viruses are the most common causes of pneumonia in young children peaking between 2-3yrs
Lobar Pneumonia Bright red/rusty sputum raised from the lungs, fibrin deposits, solidifying causing consolidation or blockage of airway passages
Bronchial Pneumonia Productive cough, shortness of breath = dyspnea
Klebisella pneumonia Extremely severe pneumonia, causes chronic ulcerative lesions in the lungs, obsesses and permanent damage There is usually some predisposing condition overall characterized by a CHRONIC DEBILITATION
Necrotizing Faciitis Transmission often person to person and fomites
