Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. while it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. when this happens, it can cause a serious infection called sepsis. sepsis can cause an individual to go into shock and bodily organs to stop functioning. symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing. which immune system component initially results in the infammation and responds quickly when staphylococcus aureus enters the bloodstream? complement system phagocytes langerhans cells b lymphocytes

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
