Micro Biology Test 4
| Disease | Key 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 gray.black 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 |
