Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine cancer, with approximately 80% of cases associated with Merkel cell polyomavirus (MCPyV). The lack of information concerning its occurrence in non-MCC immunosuppressed populations led to the investigation of MCPyV DNA in saliva and oral biopsies from 60 kidney allograft recipients and 75(More)
Our understanding of the phylogenetic and structural characteristics of the Merkel Cell Polyomavirus (MCPyV) is increasing but still scarce, especially in samples originating from South America. In order to investigate the properties of MCPyV circulating in the continent in more detail, MCPyV Viral Protein 1 (VP1) sequences from five basal cell carcinoma(More)
Simultaneous Porcine circovirus type 2 (PCV-2) and Torque teno sus virus (TTSuV) infections have been reported around the world, generally linked to severe infections. In the present study, 257 swine plasma samples from 31 swine herds located in Brazil, were PCR screened for PCV-2 and TTSuV-1/2 and correlated with clinical data. PCV-2 was detected in 25%,(More)
The aim of this study was to investigate the association of EBV and HPV with gingivitis and/or periodontitis according to the immunologic status. To this end, 74 oral biopsies from transplanted and non-transplanted individuals with the abovementioned oral manifestations were submitted to a screening by PCR for both viruses. According to the results, EBV was(More)
BACKGROUND Merkel cell polyomavirus (MCPyV), a newly described oncogenic virus, has been found in association with tumours other than Merkel cell carcinoma (MCC). As yet, little is known about the involvement or influence of MCPyV on the development of these tumours and its prevalence in various populations. AIM To assess the prevalence of MCPyV DNA in(More)
Zika virus (ZIKV) is an emergent arbovirus that has attracted attention in the last year as a possible causative agent of congenital malformation; it shows a remarkably increased microcephaly risk during otherwise healthy pregnancies. We present here an analysis of all ZIKV sequences available in Genbank up to April 2016, studying the mutations in the whole(More)
About 40 years ago, the large and small tumor antigens (LT-Ag and sT-Ag) of the polyomavirus (PyVs) simian vacuolating virus 40 have been identified and characterized. To date, it is well known that all the discovered human PyVs (HPyVs) encode these 2 multifunctional and tumorigenic proteins, expressed at viral replication early stage. The 2 T-Ags are able(More)
