Differential Viral Fitness Between H1N1 and H3N8 Avian Influenza Viruses Isolated from Mallards (Anas platyrhynchos).
of AI circulation among wild waterfowl in 2007-2008, two viruses (H3N8 and H1N1) were isolated from ducks caught in a funnel trap located in La Hulpe wetland in Belgium. H3N8 viruses were revealed to ...
A trend analysis of antimicrobial resistance in commensal Escherichia coli from several livestock species in Belgium (2011-2014).
over 4 consecutive years (2011-2014) in the official Belgian antimicrobial resistance monitoring programme. Commensal Escherichia coli strains were isolated from faecal samples of four livestock ...
Evaluation of the pathogenicity of West Nile virus (WNV) lineage 2 strains in a SPF chicken model of infection: NS3-249Pro mutation is neither sufficient nor necessary for conferring virulence.
1 North-American WNV strain. However, since 2003, WNV strains bearing the NS3P ro genotype are regularly isolated in Western-Mediterranean countries without being correlated to any virulent outbreak in vertebrates. ...
Antimicrobial resistance and population structure of Staphylococcus aureus recovered from pigs farms.
evolutions. Per farm, nose swabs were taken from 20 animals and pooled. MRSA was detected in 215 farms. Most isolates belonged to CC398 (n=211), and the remaining were ST9 /t337 (n=1), ST80 /t044 (n=2) and ...
Full-Genome Sequencing of Four Bluetongue Virus Serotype 11 Viruses.
reference strain, BTV-11 vaccine strain and a recently isolated BTV-11 field strain from Martinique. Full-genome analysis showed that these viruses belong to serotype 11/nucleotype A and cluster together with ...
First isolation, identification, phenotypic and genotypic characterization of Brucella abortus biovar 3 from dairy cattle in Tanzania.
with the RBT. Three Brucella were isolated from an aborted fetus and associated membranes. Real time PCR (IS711), Bruce-ladder and classical biotyping classified the isolates as B. abortus biovar 3. ...
Contamination of freshly slaughtered pig carcasses with enteropathogenic Yersinia spp.: Distribution, quantification and identification of risk factors.
associated with Yersinia contamination of freshly eviscerated pig carcasses were studied. Yersinia enterocolitica serotype O:3 was isolated from the tonsils and feces of 55.3% and 25.6% of pigs, and Y. ...
Detection and Isolation of Swine Influenza A Virus in Spiked Oral Fluid and Samples from Individually Housed, Experimentally Infected Pigs: Potential Role of Porcine Oral Fluid in Active Influenza A Virus Surveillance in Swine.
period in nasal swab samples. Therefore, more sensitive diagnostic methods to monitor circulating virus strains are requisite. METHODS: qRT- PCR and virus isolations were performed on oral fluid and nasal ...
Role of wildlife and domestic pigs as reservoirs for hepatitis E virus (HEV): study of the infection in suids and cervids and of the susceptibility of pigs to HEV originating from wild boa
passed in swine, and a SwHEV strain after oral inoculation. A HEV-3 subtype f isolated from the livers of two young wild boars hunted in the same Belgian forest during the same hunting and phylogenetically ...
Extensive genetic variability linked to IS26 insertions in the fljB promoter region of atypical monophasic variants of Salmonella enterica serovar Typhimurium.
Fifty-nine monophasic Salmonella enterica serovar Typhimurium isolates, collected in Belgium during the period from 2008 to 2011, have been serotyped as 4,[5]:i:- and shown to harbor an fljB coding sequence. ...
