Association of Righ-Risk Human Papillomavirus and Ureaplasma parvum Co-Infections with Increased Risk of Low-Grade Squamous Intraepithelial Cervical Lesions.

Objective: The present report investigated the rates of coinfections between high-rik human papillomavirus (hrHPV) and the most important human mycoplasmas including Mycoplasma hominis, M. genitalium, Ureaplasma urealyticum and U. parvum in cervical samples of asymptomatic brazilian population.

High molecular prevalence of HPV and other sexually transmitted infections in a population of asymptomatic women who work or study at a Brazilian university.

Sexually transmitted infections (STIs) represent a global health problem with variable prevalence depending on the geographical region and the type of population. Human papillomavirus (HPV) encompasses widespread virus types related to cervical carcinogenesis. The present study investigated the molecular prevalence of HPV and seven other important STIs in asymptomatic women working or studying at a Brazilian university.

Cervical and oral human papillomavirus infection in women living with human immunodeficiency virus (HIV) and matched HIV-negative controls in Brazil.

Background: Despite the demonstrated role of human (HPV) in the etiology of cervical cancer and the strong evidence suggesting the importance of HPV in the development of oropharyngeal cancer, several aspects of the interrelationship between HPV infection in both body sites remain unknown, specifically in female human immunodeficiency virus (HIV)-positive (HIV+) patients. We aimed to assess the prevalence, distribution, and concordance of cervical and oral HPV in HIV+ women and matched HIV-negative (HIV-) controls in Brazil.

Material And Methods: Cervical and endocervical samples for cytological screening and HPV detection and oral samples were collected from 115 HIV+ women using highly active antiretroviral therapy (HAART) and 139 HIV-matched controls (HIV-) in Maringá City, Brazil.

Zika virus infection in the genital tract of non-pregnant females: a systematic review.

This review provides a general overview on the positivity and persistence of Zika virus (ZIKV) in female genital tract (FGT) of non-pregnant women and animals, as well as in cell cultures, and its influence on FGT health. We performed a systematic review based on the PRISMA statement to identify studies focused on "Zika virus" and "non-pregnant female" in PubMed, Embase, Scopus Scholar and Web of Knowledge databases of full-text papers and abstracts published in English, with no restrictions regarding the initial date of publication, up to August 2019. Our search terms yielded 625 records, that were 108 after removal of duplicates, leaving 517 items for title and abstract reviews.

Persistence and clinical relevance of Zika virus in the male genital tract.

Zika virus (ZIKV) is a re-emerging mosquito-transmitted flavivirus associated with congenital abnormalities in newborns and with Guillain-Barré syndrome in adults. The virus can also be sexually transmitted and can persist in the male genital tract. Studies evaluating the kinetics of ZIKV in seminal shedding of men who have been infected, as well as in animal and cellular models of infection, have shown that, in addition to the testis and epididymis, the prostate and seminal vesicles could also be involved in persistent ZIKV infection.

Association of human papillomavirus and bacterial vaginosis with increased risk of high-grade squamous intraepithelial cervical lesions.

Objective: To assess the rates of co-infections between human papillomavirus (HPV) and 13 key markers of bacterial vaginosis in cervical samples by multiplex polymerase chain reaction in a population with a high rate of abnormal cytology and a positive HPV test.

Methods: The study included a total of 213 women aged 18-72 years screened using Papanicolaou smears for determining cervical abnormalities and for HPV and bacterial vaginosis by single-target and multiplex polymerase chain reaction.

Results: A total of 83 (39%) women were negative for intraepithelial lesion or malignancy cytology and 130 (61%) had abnormal cytology.

Case Reports: Prolonged Detection of Zika Virus RNA in Vaginal and Endocervical Samples from a Brazilian Woman, 2018.

Zika virus (ZIKV) infection is an emerging public health problem, associated with increased risk for Guillain-Barré syndrome and adverse fetal outcomes, including congenital microcephaly. Zika virus sexual transmission is known, but detection of the virus in different parts of the female reproductive tract is not well established. In this case report, we describe prolonged detection of ZIKV RNA in the vaginal secretion and endocervical mucosa from a Brazilian woman convalescent to ZIKV infection.

HPV Infection and Cervical Abnormalities in HIV Positive Women in Different Regions of Brazil, a Middle-Income Country.

Human papillomavirus is a virus that is distributed worldwide, and persistent infection with high-risk genotypes (HR-HPV) is considered the most important factor for the development of squamous cell cervical carcinoma (SCC). However, by itself, it is not sufficient, and other factors may contribute to the onset and progression of lesions. For example, infection with other sexually transmitted diseases such as human immunodeficiency virus (HIV) may be a factor.
