Detection of Ureaplasma Biovars and Subtyping of Ureaplasma parvum among Women Referring to a University Hospital in Morocco

Abstract EN

Objectives.

The aim of this study was to determine the prevalence of Ureaplasma biovars and Ureaplasma parvum (U.

parvum) serovars, their associated risk factors, and genital STI-related symptoms.

Methods.

DNA obtained from cervical samples of 1053 women attending the department of Obstetrics and Gynecology and the laboratory of pathological anatomy of Hassan II university hospital of Fez, Morocco, was used to detect Ureaplasma biovars (U.

urealyticum and U.

parvum) and to subtype U.

parvum by polymerase chain reaction (PCR).

Results.

Of the 1053 women examined, 25.4% (268/1053) were Ureaplasma positives.

The rates of U.

urealyticum and U.

parvum were 12.1% (128/1053) and 7% (74/1053), respectively, and the copresence of these biovars was noted in 6.3% (66/1053) cases.

The U.

parvum subtyping revealed a predominance of the serovar 3/14 (61.4%).

The association of demographics variables with Ureaplasma biovars was studied and shows that the age (“<30” years) seems to be a risk factor of Ureaplasma spp.

and U.

urealyticum carriage (OR 1.729, 95% CI [1.113-2.687] and OR 1.848, 95% CI [1.026-3.330], respectively).

There was no difference in the prevalence of Ureaplasma type regarding symptoms.

However, a significant association was found between U.

parvum serovar 1 and infertility (P=0.011).

Conclusion.

This first study conducted in Morocco provides an idea on Ureaplasma biovars and U.

parvum serovars circulating in this region, their associated risk factors, and genital STI-related symptoms.

Therefore, further studies are required to clarify and confirm the pathogenic role of these Ureaplasma species.
