Human papillomavirus (HPV) is considered the most important risk factor for the development of ano-genital region cancer in both women and men. 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. HPV DNA detection and genotyping was performed using a multiplex real-time PCR assay. In all, 1123/2312 subjects (48.57%) resulted positive for HPV DNA. In particular, HPV DNA was detected in (1056) 49.14% of females and (67) 41.10% of males. HPV co-infections were detected in 565 (24.44%) patients. High-risk and low-risk HPV genotypes were detected in 887 (38.37%) and 600 (25.95%) patients, respectively. The most prevalent HPV genotypes were HPV-42 (10.29%), HPV-16 (8.56%), HPV-31 (7.40%) and HPV-53 (7.14%). Statistically significant differences between female and male patients were not detected. Moreover, HPV prevalence remained constant in time while HPV-16, but not HPV-6, 11 and 18, showed a decreasing trend from 2013 (11.24%) to 2016 (6.67%). Other HPV genotypes showed some complex and different patterns. Our data showed an unusually high frequency of HPV-42 and a high prevalence of HPV infection in the patients analysed. Although evidence of a decreasing trend of HPV-16 could be a consequence of anti-HPV vaccination, corroboration from further studies will be needed. Moreover, the small number of studied males and the similarity to females in terms of HPV prevalence suggest that more active HPV screening and anti-HPV vaccination in the male population should be considered important tools to eliminate HPV sexual transmission.

Background: The aim of this study was the rapid identification of blaKPC gene in 38 Klebsiella pneumoniae clinical isolates with reduced susceptibility to carbapenems. The modified Hodge Test (MHT) was carried out to phenotypically determine whether resistance to carbapenems was mediated by a carbapenemase. The detection of the blaKPC gene was performed by real-time acid nucleic sequence-based amplification (NASBATM), specifically designed for the detection of KPC RNA target. Results: Thirty-two/38 isolates evaluated by MHT showed the production of carbapenemases, while all the strains exhibited the production of KPC by inhibition test with phenylboronic acid (the combined disk test with IPM/IPM plus phenylboronic acid). The detection of blaKPC gene by Nuclisens EasyQ KPC yielded positive results in 38/38 (100%) strains. The presence of blaKPC gene was confirmed in all K. pneumoniae isolates when tested by the gold standard PCR assay. Conclusions: In consideration of the serious challenge represented by infections due to K. pneumoniae it appears necessary the rapid identification of carbapenemases in clinical settings as it is made possible by the use of NASBATM assay.

PURPOSE: Genital tract infections are globally a major cause of morbidity in sexually active individuals. 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) (AnyplexTM II STI-7, Seegene, Inc., Seoul, Korea) assay. RESULTS: 455/1575 (28.89%) samples resulted positive for at least one of the targets named above. Statistically significant differences in prevalence of the pathogens between SF and SM were not detected except for UP (24.92% in SF vs 8.91% in SM). Prevalence of co-infections was 6.84 and 3.96% in SF and SM, respectively. Moreover, MH presence in SF, but not in SM, was associated with UU and UP. CONCLUSIONS: Our data suggest different patterns of infections between females and male and the importance of an increased vigilance of sexually transmitted pathogens to reduce the burden on general population and the sequelae or the complications on reproductive organs.

The tuberculosis of the ear is rare, and in most cases the clinical picture resembles that of a chronic otitis media. The diagnosis is often delayed, and this can lead to irreversible complications such as hearing loss and/or facial paralysis. In view of its rare occurrence, we report a case of primary tuberculous otitis media in a 87-year-old female patient. The diagnosis was made on the basis of both histological and microbiological findings. In particular, gene amplification techniques such as real-time polymerase chain reaction are useful method for rapid diagnosis and detecting tuberculous bacilli usually present at very low number. Early diagnosis is essential for the prompt institution of antituberculous therapy.
