When the doctor say u have a little bacteria what does that mean?

Bacteria: It's not clear from your question but you probably mean that there were some bacteria in the urine. If so, that is because you did not perform a clean catch mid-stream collection and as long as you have no symptoms it was a silly comment for him to make. Bacteria in the blood is always a potential disaster and never deserved a flippant remark so I assume that wasn't the case. Speak to him if unsur

Probably nothing.: Everyone has a little bacteria here and there. Only the "inside" of your body is truly sterile. Everything else is potentially contaminated from time to time. You might want to ask them what they really meant. I suspect that if you had an infection they would have said "infection."

Refers to the #: When doctor's say you have a little bacteria (in the urine for instance) they mean that the number of bacteria present is small (since all bacteria are small). Sometimes a "little" bacteria are not enough to cause problems depending on the location. A little bacteria in the spinal fluid is dangerous, but a little bacteria in a urine specimen may not be. Depends on the circumstances/location!
