Hi, Thanks for posting in HCM. I understand your concern. Ureaplasma parvum is a pathogenic ureolytic mollicute (mycoplasma) commonly found in healthy and diseased humans. It has been identified as being a commensal in the uterus as part of the microbiome in healthy women of reproductive age. It has been categorized as a mucosal parasite living within the genito-urinary tracts. It is not necessary to treat all cases which are tested positive and when there are no symptoms associated with it. When the general immunity decreases, infection can flare up. Spread of organism can happen with sexual contact and also by direct contact with infected material. Hence, it would be better to take proper precautions while having sexual contact. Hope the information provided would be helpful. All the best.
