In November 2017, a 15-day-old calf located in France (Haute-Savoie department) was found positive for bluetongue virus (BTV) RNA by RT-PCR. Laboratory investigations allowed the isolation and identification of the serotype: BTV-4. The analysis of the full viral genome showed that all the 10 genome segments were closely related to BTV-4 strains involved in a large BT outbreak in the Balkan Peninsula, in Italy since 2014 and in Corsica since the end of October 2016. These results together with epidemiological data suggest that BTV-4 has been introduced to mainland France from Corsica or Italy where BTV-4 outbreaks have been reported in summer and autumn 2016. This is the first report of the introduction of BTV-4 in mainland France.

Name: Transboundary and emerging diseases
Bluetongue (BT) is a vector-borne disease of immense economic importance for small and large ruminants. Despite frequent disease reports from neighboring countries, a little is known about current dis...
The epidemiological patterns of Bluetongue (BT) in North Africa and Mediterranean Basin (MB) dramatically changed by emergence of subsequent episodes of novel bluetongue virus (BTV) serotypes with hig...
India witnessed dengue outbreaks during 2017 in different parts with more than 180000 cases. There is no data on the serotypes/genotypes of dengue virus (DENV) associated with the 2017 outbreak season...
The present study was performed to detect and characterize the serotypes of fowl adenovirus associated with inclusion body hepatitis (IBH) or hepatitis-hydropericardium syndrome (HHS) in commercial po...
In 2017, highly pathogenic avian influenza A(H5N8) virus was detected in poultry in the Democratic Republic of the Congo. Whole-genome phylogeny showed the virus clustered with H5N8 clade 188.8.131.52B str...
Dengue fever, which is caused by dengue viruses, is a major health problem in subtropical regions of the world. There are four different forms (serotypes) of dengue virus that can cause d...
A Study to Evaluate the Safety, Reactogenicity, and Immunogenicity of Adenovirus Serotype 26 Based Respiratory Syncytial Virus Pre-fusion (Ad26.RSV.Pre-F) Vaccine in RSV-Seronegative Toddlers 12 to 24 Months of Age
The purpose of this study is to assess the safety and reactogenicity of an intramuscular regimen of 3 doses of 2.5*10^10 viral particles (vp) of adenovirus serotype 26 based respiratory sy...
Introduction: To date, very few studies about links between work and addictive disorders concern behavioral addictive disorders such as gambling. Such behaviours may be adaptative strategy...
Several studies have previously examined the use of botulinum toxin serotype A for myofascial pain of the neck and shoulders (cervicobrachial syndrome). These studies have suffered from: ...
The question posed by this project is that of the regional estimate of the relative importance of the risk factors of the main pathologies. Our hypothesis is that these risk factors are of...
The type species of ORBIVIRUS causing a serious disease in sheep, especially lambs. It may also infect wild ruminants and other domestic animals.
A species in the genus HEPATOVIRUS containing one serotype and two strains: HUMAN HEPATITIS A VIRUS and Simian hepatitis A virus causing hepatitis in humans (HEPATITIS A) and primates, respectively.
A serotype of the species California encephalitis virus (ENCEPHALITIS VIRUS, CALIFORNIA), in the genus ORTHOBUNYAVIRUS, causing human MENINGOENCEPHALITIS. This is the agent most responsible for California encephalitis (ENCEPHALITIS, CALIFORNIA), the most prevalent mosquito-borne disease recognized in the United States.
A genus of plant viruses in the family SEQUIVIRIDAE. Transmission is by APHIDS but depends on the presence of a helper protein encoded by the Anthriscus yellow virus, a WAIKAVIRUS. The type species is Parsnip yellow fleck virus (parsnip serotype).
One of the Indian Ocean Islands, east of Madagascar. Its capital is Saint-Denis. It was discovered in 1507 by the Portuguese and claimed by France in 1638. It was first colonized in 1662 as Isle de Bourbon but renamed Reunion in 1793. In 1946 it was made an overseas department of France. The name commemorates the reunion of the revolutionaries from Marseilles with the National Guard in Paris in 1792.
