flora is a small yeast A staphylococci B diphtheroids C Candida spp D Malassezia spp The growth of P acnes within hair follicles in many individuals leads to A eczema B carbuncles C boils D acne The principal species of Staphylococcus found on the skin is A aureus B acnes C pyogenes D epidermidis The bacteria that appear to maintain balance between the members of the normal flora and play a vital role in limiting colonization by pathogens are A staphylococci B diptheroids C Candida spp D Malassezia spp The member of the normal flora sometimes considered responsible for tinea versicolor is A staphylococci B diptheroids C Candida spp D Malassezia spp Which is deemed the most serious staphylococcal skin infection A tinea versicolor B folliculitis C furuncles D carbuncles A protein associated with a more virulent form of Staphylococcus is A leukocidin B mannose C streptokinase D coagulase Respiratory diseases The eyes are protected from infection by A the washing action of the tears and eyelids B the chemical action of lysozyme C the use of contact lenses D the dryness of the eye surface E the washing action of the tears and eyelids AND the chemical action of lysozyme The cause of strep throat is A Staphylococcus aureus B Streptococcus pyogenes beta hemolytic group A C Staphylococcus pyogenes alpha hemolytic group B D Streptococcus pneumoniae The disease characterized by the appearance of a toxin mediated rash that spares the area around the mouth and causes the tongue to look like the surface of a ripe strawberry is A measles B chickenpox C strep throat D scarlet fever Diphtheria toxin works on A lysosomes B mitochondria C chloroplasts D elongation factor 2 Which is used in the vaccination for C diphtheriae A protein A B M protein C toxoid D red blood cells

media and sinusitis are usually preceded by a n A middle ear infection B pseudomonal infection C oropharyngeal infection D nasopharyngeal infection Otitis media probably develops from an infection that spread A from the outer ear to the middle ear B from the sensory neurons of the middle ear C through the tympanic membrane D upward through the eustachian tube Most colds are probably caused by A rhinovirus B S aureus C Pseudomonas sp D E coli The reservoir of the common cold is the A family pet B human C infected fomite D fruit Colds are effectively treated with A antibiotics B aspirin and
