5 EXAM QUESTIONS AND ANSWERS 2022
◉ Strep hemolysis. Answer: Alpha, Beta and Gamma hemolysis
◉ Strep virulence factors. Answer: M proteins and hyaluronic acid
capsule
◉ M proteins. Answer: Membrane proteins disrupting immune
response by suppressing opsonization and phagocytosis
◉ Hyaluronic acid capsule. Answer: hides bacteria as it is also
present in human tissue. Has a sticky carbohydrate capsule to
increase adhesion
◉ Strep groups associated with human disease. Answer: A, B, D
◉ Lancefield groupings. Answer: A, B, C, D based on similarities in
carbohydrate composition of antigens in cell walls of strep
◉ Streptococcal pharyngitis. Answer: Strep throat - group A
,◉ Strep throat symptoms. Answer: Fever, red and sore throat, pus
spots on back of throat, tender and swollen glands of neck
◉ Strep throat transmission. Answer: Respiratory droplets
◉ Strep throat complications. Answer: Rheumatic fever, also
complications within ear, lung, or sinus cavities
◉ Strep throat treatment. Answer: antibiotics
◉ Rheumatic fever incidence. Answer: Occurs in 3% of untreated
strep throat cases, most common in 5-15 year olds
◉ Rheumatic fever symptoms. Answer: Present in 2-3 weeks after
initial infection; inflammation of joints, jerking movements, nodules
beneath skin, red areas on skin surface. Autoimmune inflammation
of heart valves and other organs due to similarities of strep and
human antigens.
◉ Treatment of rheumatic fever. Answer: Prompt treatment with
penicillin
◉ Streptococcal Septicemia. Answer: Sepsis or blood poisoning most
commonly caused by GBS, E. Coli, or staph aureus
, ◉ Sepsis symptoms. Answer: Fever, chills, rapid breathing, increased
hear rate
◉ Septic shock symptoms. Answer: fever or hypothermia, decreased
BP leading to tissue death, organ failure and death
◉ Sepsis treatment. Answer: Antibiotics, IV fluids, oxygen
◉ Staphylococcus morphology. Answer: cocci in clusters
◉ Staph gram status. Answer: gram-positive
◉ Staph motility. Answer: non-motile
◉ Staph catalase status. Answer: Catalase positive, facultative
anaerobe
◉ Staph oxidase status. Answer: oxidase negative
◉ Staph coagulase status. Answer: coagulase positive
