C., Ribalta, J. C. L., Leite, K. D. P. F., Schimidt, M., and Speck, N. M. D. G., Expression of human papillomavirus E6 and E7 oncoprotein mRNA in women with low-grade squamous intraepithelial lesions or less, vol. 15, p. -, 2016.

We verified the prevalence of human papillomavirus (HPV) E6/E7 protein mRNA expression in patients with low-grade squamous intraepithelial lesions (LSILs) and negative cervicovaginal cytology. To investigate the relationship between mRNA expression and viral infection type, we assessed genotyping in single infections. Samples from 825 women were submitted to the E6/E7 survey. We noticed a larger percentage of E6/E7 mRNA expression in the atypical squamous cells of undetermined significance (ASC-US) and LSIL cytologies.

Molecular analysis and conventional cytology: association between HPV and bacterial vaginosis in the cervical abnormalities of a Brazilian population

G., Molecular analysis and conventional cytology: association between HPV and bacterial vaginosis in the cervical abnormalities of a Brazilian population, vol. 14, pp. 9497-9505, 2015.

We investigated the association between bacterial vaginosis (BV) and human papillomavirus (HPV) infection in Papanicolaou smears in a Brazilian population. Cross-sectional analysis was performed on 673 samples collected from women attending public health centers in Olinda (PE, Brazil) by conventional cytology methodology and molecular analysis, PCR tests (GP5+/6+ and MY09/11). Cytological abnormalities, BV, and HPV-DNA were detected in 23 (3.4%) samples, 189 samples (28.1%), and 210 samples (31.2%), respectively.
