| Successive disease outbreaks in oyster (Crassostrea gigas) beds in France have resulted in dramatic losses in production, and subsequent decline in the oyster-farming industry. Deaths of juvenile oysters have been associated with the presence of a herpes virus (OsHV-1 µvar) and bacterial populations of the genus Vibrio. Although the pathogenicity of OsHV-1 µvar, as well as several strains of Vibrio has been demonstrated by experimental infections, our understanding of the complexity of infections occurring in the natural environment remains limited. In the present study, we use specific-pathogen-free (SPF) oysters infected in an estuarine environment to study the diversity and dynamics of cultured microbial populations during disease expression. We observe... |

| The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS:Veterinary Services (VS). The NAHMS Equine '98 Study was designed to provide information about the nation's equine population. Twenty-eight states were included in the study. The USDA's National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically-valid sample such that inferences could be made to all equids and operations with equids in the 28 states. For the purposes of the study, equids included domestic horses, miniature horses, ponies, donkeys/burros, and mules. For Part III of the study, data were collected by Federal and State Veterinary Medical Officers and Animal Health Technicians between March 16, 1998, to April 10, 1998, from... |

| Depuis 1991 , des mortalités massives sporadiques sont rapportées, en France, de manière régulière chez des larves et des juvéniles de différentes espèces de mollusques bivalves marins. Certains de ces épisodes de mortalité ont pu être associés à la détection de virus. Ces derniers par leur morphologie, leur cycle de réplication et leur localisation ont été apparentés à la famille des Herpesviridae. Cependant, les outils de diagnostic disponibles jusqu'alors (histologie et microscopie électronique à transmission) n'étaient pas adaptés à l'étude de ces virus du fait de leur manque de spécificité et de la lourdeur de leur mise en oeuvre. Par ailleurs, se posait la question de l'implication des virus détectés dans les phénomènes de mortalité observés. En... |

| Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD) - syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum and other non-STD disorders (NSTD) - Behçet's syndrome, pemphigus, Crohn's disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections... |

| Although viruses have been associated with mortality outbreaks in different mollusc species, little information is available on their exact affiliation and taxonomic position. Herpes viruses have attracted particular attention because of their economic and ecological impact on both farmed and wild marine molluscs over the past 20 years. Investigations based on molecular approaches have been carried out on the herpes virus infecting Pacific oysters in France. Molecular and ultra-structural data were used to classify the virus under the name ostreid herpesvirus 1 (OsHV-1), as the first known species in the family Malacoherpesviridae. Since 2008, massive mortality outbreaks were reported in several Crassostrea gigas oyster farms in France, Ireland, and the... |

| This study aims to improve understanding of causes of mortalities in oyster Crassostrea gigas in pertuis charentais related to environmental parameters and the kinetics of targeted infectious agents, such as bacteria Vibrio splendidus (group ) and V. aestuarianus and Ostreid herpesvirus OsHV-1. Two sampling campaigns were carried out on the site of Agnas in 2009 and 2010, before, during or following mortality events of spat from March to September. The approach is to detect and quantify in short time step infectious agents from tissues of farmed oysters placed on rack and in various samples taken nearby: native oysters and other species (wild mussels and barnacles), seawater and sediment. With physical and chemical automatic probes placed on the site,... |

| P>Summer mortality is a phenomenon severely affecting the aquaculture production of the Pacific oyster (Crassostrea gigas). Although its causal factors are complex, resistance to mortality has been described as a highly heritable trait, and several pathogens including the virus Ostreid Herpes virus type 1 (OsHV-1) have been associated with this phenomenon. A QTL analysis for survival of summer mortality and OsHV-1 load, estimated using real-time PCR, was performed using five F-2 full-sib families resulting from a divergent selection experiment for resistance to summer mortality. A consensus linkage map was built using 29 SNPs and 51 microsatellite markers. Five significant QTL were identified and assigned to linkage groups V, VI, VII and IX. Analysis of... |
