Which of the following host defenses is considered the most effective in combating S. aureus infection?
LiRa [457]

Phagocytic response is considered the most effective host defenses in combating S. aureus infection.

<h3>What is phagocytic response?</h3>

Phagocytosis is a type of cell response that plays a key role in the course of an immune response as well as in the remodeling of tissues and the healing of wounds. Professional phagocytes are specialized cells that can carry out this task quite effectively.

<h3>What is S. aureus infection?</h3>

It has long been known that S. aureus is one of the most significant germs that harm humans. It is the main contributor to skin and soft tissue infections such cellulitis, furuncles, and abscesses (boils). Boils are the most typical staph infection form. This is a pus-filled pocket that forms in an oil gland or hair follicle. Typically, the skin around the infected area turns red and swells. To treat staph infections, doctors frequently administer cefazolin, nafcillin, oxacillin, vancomycin, daptomycin, and linezolid. Vancomycin may be necessary for staph infections that are severe. This is due to the fact that a large number of staph bacterium strains have developed resistance to other common antibiotics.

Thus from above conclusion we can say that phagocytic response is considered the most effective host defenses in combating S. aureus infection.

charle [14.2K]
Long ears have to be dominant:

If this IS true then these would be your 'parents':

L = long ears
l = curly ears

LL x ll

If you cross the homozygous recessive curly eared rabbit (ll) with homozygous dominant long eared rabbit (LL) you would get 100% Ll - all would look long eared.
