Daughter had bacteria in urine but urine culture cam back negative was sent out to find exact bacteria but came back negative why is that?

UTI?: Your question isn't entirely clear, but it sounds like your girlfriend has a urinary tract infection. UTI in women sometimes is triggered by sex, but it's not an STD -- i.e. she didn't catch the infection from you. Sex sometimes massages a woman's natural bacteria into the urethra (urinary opening). Your GF should discuss this with her doctor if you remain concerned or uncertain. ...Read more

Are these bad results in my urine test or no? URINE EPITHELIAL CELLS-None seen Mucus, UA-Present BACTERIA IN URINE-Few

Not really: In a normal urine, there shouldn't be any epithelial cells. Trauma or infection can cause them to be present. Few bacteria are not necessarily a bad sign. There is a condition called asymptomatic bactiuria (which just means bacteria in the urine without there being an infection). I'm not very concerned about the mucus. This should all be correlated with your symptoms of course. ...Read more

I am a male my female partner has bacteria in urine or vaginosis. For me the male will ciproflaxin treat me. My penis is shriveled and foreskin snug?

Something is wrong: Vaginosis causes an odor like stinky fish, but it does not affect the male partner. The typical treatment is metronidazole. Bacteria in urine should be treated if she has symptoms. If you have issues with your penis, see a urologist. Your problem, if you really have one, is not related to your partners'. You may need a dr for flank pain. ...Read more

My dr ordered a culture of my urine and a complete semen analysis. Does this check for all bacteria and infections or would a semen culture be helpful also? Or is it not needed with the first two tests?

Depends: You do not state the reason for the study but i'll assume a prostate problem. A regular urine culture checks for common bacteria but not gonorrhea or chlamydia if a std might be an issue. A semin analysis would normally examine the components and ratio of active to inactive sperm. If your doc ordered the original culture with a std in mind, s/he probably has all needed info. You could ask. ...Read more
