Background And Objectives: Human papillomavirus (HPV) is the most prevalent etiological agent of viral sexually-transmitted infection. This study retrospectively evaluated the impact of a switch to a real-time PCR assay in the HPV prevalence and genotypes distribution by a quasi-experimental before-and-after approach.
Materials And Methods: In total, 1742 samples collected from 1433 patients were analyzed at the UOC Microbiology and Virology of Policlinico of Bari, Italy.
Klebsiella pneumoniae is a common nosocomial pathogen involved in many infectious diseases such as bacteraemia, urinary and respiratory tract infections. It is responsible for the rise in morbidity and mortality rates since most clinical isolates exhibit resistance to several antibiotics. Moreover, the epidemiology of these nosocomial infections is variable across countries and regions.

From January 2012 to February 2018, 2848 cervico-vaginal swabs were analysed in the UOC Microbiology and Virology of Policlinico of Bari, Italy. HPV DNA detection was performed using initially nested-polymerase chain reaction (PCR) and subsequently multiplex real-time PCR assay.

The increasing frequency and severity is attributed to highly virulent ribotypes such as 027. The aim of this study was to retrospectively analyze the prevalence of CDI and ribotype 027 in 481 clinical samples collected from hospitalized patients and sent to the laboratory of molecular biology, UOC Microbiology and Virology, Azienda Ospedaliera-Universitaria, Policlinico of Bari, Italy.

Whereas low-risk genotypes are responsible for cutaneous and genital lesions, high-risk genotypes are associated with ano-genital cancer. The aim of this study was to retrospectively analyse the prevalence, genotype distribution and temporal dynamics of HPV infection in 2312 specimens from 2312 subjects (2149 women and 163 men) who attended the laboratory of molecular biology, UOC Microbiology and Virology, Azienda Ospedaliera-Universitaria, Policlinico of Bari, Italy.

The aim of this study was to investigate the prevalence and associations of co-infections of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Mycoplasma hominis (MH), Mycoplasma genitalium, Ureaplasma urealyticum (UU) and Ureaplasma parvum (UP) in specimens collected from female (SF) and male (SM) patients.
Methods: 1575 samples from 1575 individuals from the geographical area around Bari, Apulia region in Southern Italy, were collected and analyzed by a multiplex Real-Time PCR (mRT-PCR) (Anyplex II STI-7, Seegene, Inc.
