Eosinophils-orange granules and bilobed nucleus; destroys pathogensBasophils-constricted nuclei; releases potent chemical mediatorsLymphocytes-B and T cells involved in the specific immune responseMonocytes/Macrophages-large nucleus; phagocyticCoagulase-coagulates plasma and bloodHemolysin-lyse RBCsLeukocidin-lyse neutrophils and macrophagesEnterotoxins-shut down the gut; induce nausea, vomiting, and diarrheaExfoliative toxin-skin to come offRickettsia rickettsii-Rocky Mountain Spotted FeverCoxiella burnetti-Q fever, pneumoitis, fever, and hepatitisTreponema pallidum-syphilisBorrelia burgdorferi-Lyme diseaseRickettsia prowazekii-epidemic typhusChlamydia-ocular trachoma- sever infection, derforms eyelid and cornea, may cause blindness -inclusion conjunctivitis- occurs as babies pass through birth canal; prevented by prophylaxis -STD- urethritis, cervicitis, salpingitis (PID), infertility, scarring -lymphagramula venereum- disfiguring disease of external genitalia and pelvic lymphatics -C. pneumoniae- causes an atypical pneumonia that is serious in asthma patients -C. psittaci- causes ornithosis, transmitted to humans from bird vectors; highly communicable among all birds; pneumonia or flulike infection with fever, lung congestionVeillonella, Bacteriodes, and Fusobacteria-dental cariesCampylobacter jejuni-ulcersMycoplasma pneumoniae-primary atypical pneumonicVibrio cholerae-choleraScarlet fever-high fever, bright red, diffuse rash over the face, trunk, inner arms and legs, and even tongue -strain of S. pyogenesAcute glomerulonephritis-a disease of the kidney glomerulus and tubular epithelia -damage can be traced to a type III hypersensitivity, occurring when immune complexes deposited in the epithelia inflame and damage the filtering apparatusPharyngitis-strep throat; organism multiplies in the tonsils or pharyngeal mucous membranes, causing redness, edema, enlargement, and extreme tenderness, which make swallowing difficult and painful, accompanied by fever, headache, nausea, and abdominal pain, and possible swollen lymph nodesErysipelas-form of skin infection; pathogen enters wound or incision on the face or extremities and spreads to dermis and subcutaneous tissue -symptoms: edema and redness of skin, fever, and chillsRheumatic fever-a delayed inflammatory condition of the joints, heart, and subcutaneous tissue -carditis, an abnormal electrocardiogram, painful arthritis, chorea, nodules under the skin, and feverM-proteins- (frimbrae) spiky surface projections that contribute to virulence by resisting phagocytosis and improving adherenceStreptolysin-rapidly injure many cells and tissues, including leukocytes, liver, and heart muscleStreptokinase-digest fibrin clotsHyaluronidase-breaks down connective tissueErythrogenic toxin-key toxin of scarlet fever -induces fever by acting upon the temperature regulatory center
