The Prevalence of High Carcinogenic Risk of HPV Genotypes among HIV-Positive and HIV-Negative MSM from Russia.

Objective: Men who have sex with men (MSM) have a high risk of lifelong anal cancer caused by high-risk human papillomavirus (HR HPV) infections. The aim of this study was to investigate the prevalence of anal canal HR HPV infection among men who have sex with men (MSM) with and without HIV infection in Moscow (Russia). We evaluated associations of some HIV coinfections (HSV and CMV) and HPV distribution among MSM with and without HIV infection.

[Genetic determinants of antibiotic resistance in oropharyngeal streptococci in patients with chronic obstructive pulmonary disease and in those with asthma].

Aim: To identify oropharyngeal Streptococcus species and to analyze the genetic determinants of antibiotic resistance in patients with asthma and in those with chronic obstructive pulmonary disease (COPD).

Material And Methods: An experimental diagnostic Streptopol+ (Lytech Co. LTD) panel based on a multiplex real-time PCR was applied to investigate the representation of antimicrobial resistance genes (mef and ermB) and the species composition of streptococci isolated from oropharyngeal swab samples from 89 patients with stable COPD and from 51 patients with asthma.
