Epidemiological study of bovine norovirus infection by RT-PCR and a VLP-based antibody ELISA.
Feces Gastroenteritis Norovirus Phylogeny Reverse Transcriptase Polymerase Chain Reaction Seroepidemiologic Studies Abstract: Noroviruses, belonging to the family Caliciviridae, have been identified in ...
International agreement to join forces in synthesizing evidence on new methods for cervical cancer prevention.
line with the pooled estimates of the relative sensitivity derived from cross-sectional studies. From two randomised trials, also the longitudinal outcomes observed at the second screening round were ...
Humoral, cell-mediated and mucosal immunity induced by oculo-nasal vaccination of one-day-old SPF and conventional layer chicks with two different live Newcastle disease vaccines.
chickens limited, if not completely abrogated, their immune responses to vaccination. This study increases our understanding of the protective immune response against Newcastle disease virus (NDV) and ...
Bluetongue virus detection by real-time RT-PCR in Culicoides captured during the 2006 epizootic in Belgium and development of an internal control.
the local vector species, and the other to study their population dynamics. In the vector study, Culicoides were captured near farms with recently infected cattle or sheep; in the population study ...
Proof of concept for the reduction of classical swine fever infection in pigs by a novel viral polymerase inhibitor.
potent in vitro antiviral activity against pestiviruses including classical swine fever virus (CSFV). This study analysed whether the lead compound, BPIP, was able to reduce virus replication in infected ...
Experimental reproduction of bluetongue virus serotype 8 clinical disease in calves.
serotype 8 (BTV-8) in Europe has been characterized by the manifestation of clinical signs in infected cattle. In order to study the pathogenesis of BTV-8 in this host, an animal model able to reproduce the ...
Molecular genetics of para-aminosalicylic acid resistance in clinical isolates and spontaneous mutants of Mycobacterium tuberculosis.
dysfunctional polypeptide. The MIC was determined by Bactec/Alert and dilution assay. Sixty-three percent of the PAS-resistant isolates had no mutations in the nine genes considered in this study, revealing that ...
Surveillance of antibiotic susceptibility patterns among Shigella sonnei strains isolated in Belgium during the 18-year period 1990 to 2007.
Shigella sonnei Abstract: This study was conducted to determine the frequency and pattern of antimicrobial susceptibility of Shigella sonnei, the predominant species causing shigellosis in Belgium. Between ...
Enterotoxigenic coagulase positive Staphylococcus in milk and milk products, lben and jben, in northern Morocco.
se genes were detected in 56.5%. SEA and sea were most commonly detected. For newly discovered se genes among CPS isolates tested in this study, except the seh gene which was revealed in four isolates ...
