Recently a novel infectious human retrovirus the xenotropic murine leukemia virus-related virus XMRV has been identified in cohorts of patients with either a familial type of prostate cancer or chronic fatigue syndrome. The apparent unrelatedness of these diseases raised the question of the potential involvement of XMRV in other diseases. Here we investigated the presence of XMRV in a selection of pediatric idiopathic infectious diseases with symptoms that are suggestive of a retroviral infection as well as in children with respiratory diseases and in adult patients with spondyloarthritis SpA . Using a XMRV env-nested PCR we screened 72 DNA samples obtained from 62 children hospitalized in the Montpellier university hospital France for hematological neurological or inflammatory pathologies 80 DNA samples from nasopharyngeal aspirates from children with respiratory diseases and 19 DNA samples from SpA. None of the samples tested was positive for XMRV or MLV-like env sequences indicating that XMRV is not involved in these pathologies. Findings Retroviruses have been isolated from a wide variety of animal species and have been linked to a broad range of diseases including neoplasia non-neoplastic hematological or inflammatory diseases immunodeficiencies and neurodegenerative and respiratory syndromes 1-3 . However in humans it was not until the early 1980 s that two pathogenic retroviruses were isolated a deltaretrovirus the human T cell leukemia virus HTLV and a
