### input:
I have had two urine cultures done in the last 3 weeks. The first one indicated that I showed 10,000 - 25,000 cfu per ml. Dr. prescribed cipro 500mg, but test said it also appears susceptible to levofloxacin, nitrofurantoin, penicillin and vancomycin. I have no symptoms but am quite nervous about taking any of these, and regarding cipro - especially because of the side affects in joints - I have an elevated ra factor. (plus vit d and b12 deficiency) I had a second culture done and while I don t know the results, Dr s nurse said to fill cipro and it s not a big deal. I ve been told in the past that I have metro valve prolapse and to take antibiotics before dental work and was told I didn t need to any more. 4 questions: Is this level of bacteria alarming? Is it possible this is in my bloodstream and dangerous? What penicillin do they mean, amoxicillin? Is there any healthier way to treat the bacteria in a more natural, less damaging to good bacteria way?

### output:

For urinary tract infection to be diagnosed, the bacterial count needs be above 10^5 i.e. 10,00,000. Unless that is the case, the count is not considered to be high. However, your doctor has decided to play safe and given the antibiotics. Ciprofloxacin can be taken safely, and you need not worry about that. Please complete the full course of antibiotics as prescribed. Though there is a possibility of the bacteria being in the blood stream, the chances are quite less as you do not have other symptoms. Amoxicillin is an antibiotic of penicillin class but not same as penicillin. A healthier way to manage such bacteria is to Chat Doctor.  You also need to maintain proper hygiene.
