So sepsis is a bacteria in the bloodstream?

If sepsis is a bacteria in the bloodstream can it happen when you have a blood transfusion or kidney removal or how does sepsis get in the blood?

Sepsis (in Greek 危萎蠄喂蟼, putrefaction) is a serious medical condition caused by a severe infection. The more critical subsets of sepsis include severe sepsis (sepsis with acute organ dysfunction) and septic shock (sepsis with refractory arterial hypotension). If a proven source of infection is lacking but the other criteria of sepsis are met the condition typically meets the criteria for systemic inflammatory response syndrome (SIRS); the exception is the condition greater than 10% band forms (this is not a part of the SIRS definition).

Septicemia is sepsis of the bloodstream caused by bacteremia, which is the presence of bacteria in the bloodstream. The term septicemia is also used to refer to sepsis in general.
Sepsis can occur when there is an invasive procedure, any surgery, if the wounds are not properly tended to, or it can result from any infection in the body going untreated and teh bacteria growing out of control

bacterimia is bacteria in the blood, sepsis is bacteria in the blood that are making you very sick (make you go into shock). this is not usually associated with blood transfusions or any specific type of surgery. bacteria are more likely to cause problems in the blood of people who have immune system problems such as HIV or SCID, have had their spleens removed in the past, or who are on immune-suppressive medications like steroids or chemotherapy. babies and old people are most likely to be affected.

so, sepsis usually occurs in someone who is already sick from other reasons. the bacteria can gain entry from having pneumonia or a urinary tract infection, for example. they can also grow on long-term IVs. the important thing to remember is that in most young, healthy people, bacteria getting into the blood will quickly be killed by the immune system.

Sepsis is a bad thing to get. It gets in system through the wound. I have never heard of sepsis being transmitted through blood transfusion.

Sepsis is a severe systemic infection. It's unlikely that you would become septic through blood transfusion. The screening process is continually improved. With nephrectomy, as with any invasive procedure, there is always a risk for infection but it would most likely be local rather than systemic. And in any case, IV antibiotics would be part of postop care. Sepsis occurs because bacteria can enter the blood at any time and be carried from an infected organ or part of the body to another thus infecting other body parts or organs. Sepsis isn't just bacteria in the blood, it's severe bacterial infection throughout the body.

My grandmother got sepsis when she stepped on a nail.

My mom died from sepsis from a kidney infection, when it spread.

I wouldn't worry so much about a blood transfusion. Every effort is made to ensure it is a sterile procedure. I couldn't answer as to the kidney.
