Generally speaking, several species of mycoplasmas are pathogenic in humans, including Mycoplasma pneumoniae, Mycoplasma hominis, ureaplasma urealyticum and mycoplasma genitalium. MH, UU and MG can cause urogenital tract infection.
Female mycoplasma infection, also known as Nongonococcal urethritis, is diagnosed through the test of vaginal discharge and urine. If mycoplasmas are found proliferating and reproducing in great number at the sites of inflammation, a mycoplasma infection can be diagnosed. For example, in the case of urethritis, a great deal of mycoplasmas would be found in urine. In the case of vaginitis, a lot of mycoplasmas would be found in vaginal discharge. As for male patients, the diagnosis involves observing signs and symptoms and analyzing urethral discharge. Urine is often collected in the morning. If the discharge is present, a sample is collected and cultured to determine the presence of and identify bacteria.
Culture: put the sample into the incubator of 370С for one to three days, and observe the changes of color of culture medium every day. If the liquid culture medium changes from yellow to red, clear and transparent, a preliminary judgement could be made: Mh or Uu is positive. If the liquid culture medium is cloudy, it is the false positive response.
