Possible role of bacterial and viral infections in miscarriages.

Objective: To determine the role of infections in miscarriages. Chorionic villi from aborted material were subjected to cytogenetic evaluation and analyzed for the presence of Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, human cytomegalovirus (HCMV), adeno-associated virus (AAV), and human papillomaviruses (HPV).

Design: Retrospective study.

Human papillomavirus, cytomegalovirus, and adeno-associated virus infections in pregnant and nonpregnant women with cervical intraepithelial neoplasia.

Two hundred eight cervical specimens from two groups of subjects, 165 nonpregnant women and 53 pregnant women with cervical intraepithelial neoplasia (CIN) of grades I to III, were positive by PCR analyses for human papillomaviruses (HPVs), adeno-associated virus type 2 (AAV 2), and human cytomegalovirus (HCMV) in 67, 6, and 4.1% of the cases, respectively. The presence of AAV 2 infection was more frequently associated with pregnancy (17 versus 2.

[Detection of human papillomaviruses and other agents causing sexually transmitted diseases with molecular diagnosis methods].

Causative agents of sexually transmitted diseases (STD) are different types of bacteria, viruses, fungi and protozoa. The last two decades of the twentieth century were marked with a sudden rise in the number of cases of STDs. Human immunodeficiency virus (HIV), which emerged in the 1980s, is the most prominent STD agent because of its fast spread and severity of the disease it causes, acquired immunodeficiency syndrome (AIDS).
