1. Bordetella pertussis 2. Pseudomonas 3. Yersinia pestis a. sylvatic plague b. urban plague c. flea vector |
1. Causes pertussis aka whooping couch, respiratory syndrome. Transmission direct contact or inhalation. Toxins destroy ciliated cells 2. Soap dish disease, nocicomial disease 3. Black plague, capsules & proteins protect against phagocytosis, Coagulase test, Toxins: endotoxin & murine toxin a. contact w/wild animals b. domestic animals and humans c. bacteria multiply in gut, block esophagus keep biting |
|
|
Pathology of Plague: 1. Bubonic 2. Septicemic 3. Pneumonic |
1. Flea bites, causes necrosis & swelling in groin, enlarged lymph node (Bubo = huge swelling) 2. progression to massive growth, coagulation - cuts of blood supply, tissue nuerosis (black plague) 3. Infection localizes to lungs, highly contagious |
|
|
1. Pseudomonas aeruginosa |
1. Considered normal flora, resistant to disinfectants, aerobic respiration, opportunistic (Immune compromised) causes nosocomial infections, grape-like odor, greenish-blue pigment, lechions |
|
|
Atypical Pneumonia (Mycoplasma pneumoniae): 1. Legionella pneumophila 2. Coxiella brunetii 3. Chlamydia pneumoniae 4. Chlamydia psittaci |
1. Distributed in water, amebas, nosocomial disease, fever, cough, diarrhea, pneumonia |
|
|
1. Rickettsia 2. Chlamydias (Chlamydia trachomatis) |
1. Obligate parasites, enter endothelial cells cause necrosis of vascular lining (Rocky mountain fever - zoonosis, spotted rash CNS 2. Obligate parasites - attacks mucous membrances, GI tract & lungs (STD) - urethritis, scarring, infertility, pelvic disease |
|
|
1. Treponema pallidum (STD) 2. Syphilis (3 Stages) & Congenital |
1. Strict parasites, human transmission, causes syphilis - painless (spirochetes bind to epithelium & moves into circulation, causes lesions and blood during first 2 stages) 2. Primary - hard chancre at site, fluid contagious / Secondary - red-brown rash (whole body) / Tertiary - can last 20 yrs neural, cardiovascular, gummas develop, abnormalities, discharge, skin eruptions |
|
|
1. Borrelioses a. B. hermsii b. B. burgdorferi |
1. anthropod (animal) vector a. relapsing fever (mammalian reservoirs) parasite constantly changing high fever b. Lyme disease - transmitted by ticks, (Bull's eye rash) can be cardiac and neurological |
|
|
1. Vibrio cholera 2. Helicobacter pylori 3. Mycoplasmas (M. pneumoniae) |
1. Comma shape, ingested, small intestine, electrolyte and water loss (Rice water stool, particles of intestines) 2. Causes stomach and duodenal ulcers, produces large amounts of urease, same receptors as O positive 3. Walking pneumonia, slowly spreads over internal respiratory surfaces |
|
|
Kingdom Fungi (domain = eukaria) (2) groups / Mycoses 1. Fungal Morphologies: a. Mold - Hyphae (2) types / Mycellium b. Yeast c. Thermal dimorphism |
Macroscopic & Mircoscopic / Disease caused by fungi *majority unicellular some can create colonial / all heterotrophic a. Cell wall = chitin, energy from glycogen nonmotile (Conidia (spores)) Hyphae - long tubes with spores, can divide by cross walls called septate / vegetative - digest and absorb (growing&feeding) reproductive - produce spores (zygote) / Mycellium = visible mass b. uniform texture (false hyphae) - divides and separates , beta-glycan wall (budding) c. 30 C - Mold / 37 C - Yeast |
|
|
1. Fungal reproduction 2. Budding in Yeast 3. Fungal Classifications 4. Diagnosis of 5. Pathogenesis: Primary / Subcutaneous / Cutaneous & Superficial |
1. Sexual - spores follow fusion of neg and pos strains and form sexual structures 2. Cloning 3. Yeast vs Mold / Asexual vs Sexual (Zygomycota, Ascomycota, Basidiomycota = both) / Land vs Water 4. Physiological / Genetics / Staining (Fungi=black, all else green) Reverse - Fungi different colors on bottom / Media = Sabdex 5. Respiratory / Skin/trauma / Contaminate Skin |
|
|
1. Systemic infections by 4 pathogens 2. Histoplasma capsulatum 3. Coccidioides immitis (coccidioidomycosis) 4. Blastomyces dermatitidis (Blastomycosis) 5. Paracoccidioides brasiliensis (Paracoccidioidomycosis) |
1. Restricted endemic regions, floating through air, germinate in lungs, can be systemic, all result in immunity 2. Ohio valley fever, soil w/ nitrogen / Treated by amphotericin B 3. Inhaled, creates spherules in lungs 4. dimorphic, lives in soil, converts to yeast and multiplies in lungs 5. Lung infection from inhalation of spores (flower appearance) |
|
|
1. Subcutaneous mycoses 2. Sporothrix schenckii (Sporotrichosis) 3. Mycetoma 4. Dermatophytoses (3) geneses |
1. Transmitted into traumatized skin, progressive disease 2. Rose gardeners disease, decomposes in soil, infects appendages and lungs 3. Soil implant in skin, tumorlike disease, may cause loss of limbs 4. Infects skin, hair, nails (Ringworm) (Trichophyton / Microsporum / Epidermophyton) Long infected period |
