How to evaluate emerging technologies in cervical cancer screening?
questions. We observe that good guidelines on assessment of evidence for screening questions are currently lacking. Guidelines for diagnostic research (STARD), involving systematic application of the reference ...
Prior infection with an H1N1 swine influenza virus partially protects pigs against a low pathogenic H5N1 avian influenza virus.
A Virus, H5N1 Subtype Neuraminidase Orthomyxoviridae Infections Swine Abstract: Most humans lack virus neutralizing (VN) and haemagglutination inhibition (HI) antibodies to H5N1 avian influenza viruses (AIV ...
Prevalence of enterotoxigenic Escherichia coli virulence genes from scouring piglets in Zimbabwe.
strains lacking tested fimbriae genes were characterized using transmission electron microscopy, agglutination and agglutination inhibition tests. Approximately 32% of the 1,984 isolates tested positive for ...
Liver X receptors contribute to the protective immune response against Mycobacterium tuberculosis in mice.
mice solely deficient in LXR alpha, but not those lacking only LXR beta, mirrored the susceptibility of the Lxra-/-Lxrb-/- animals. Lxra-/-Lxrb-/- mice failed to mount an effective early neutrophilic ...
Characterization of pathogenic and resistant genome repertoire reveals two clonal lines in Salmonella enterica subsp. enterica serovar Paratyphi B (+)-tartrate positive.
strains possessed additional virulence determinants. The Salmonella genomic island 1 was only found in O:5 positive strains. Five monophasic Salmonella 4,5,12:b:- lacking the phase-2 flagellar antigen were ...
An outbreak of measles in orthodox Jewish communities in Antwerp, Belgium, 2007-2008: different reasons for accumulation of susceptibles.
reasons for this outbreak were diverse: cultural factors, misinformation on vaccination by some medical doctors and the lack of a catch-up vaccination programme in private Jewish schools. The identification ...
Comparison of classical serotyping and PremiTest assay for routine identification of common Salmonella enterica serovars.
strains (90.8%) by serotyping, while the remaining 69 strains were found to be nontypeable due to either a lack of surface antigen expression or autoagglutination properties. When the PremiTest assay ...
Validation of the analysis of the 15+1 European-priority polycyclic aromatic hydrocarbons by donnor-acceptor complex chromatography and high-performance liquid chromatography-ultraviolet/fluorescence detection
of European PAH are lacking, a new method for their analysis in food is proposed. The donnor-acceptor complex chromatography (DACC) is used as clean-up step and high-performance liquid ...
Immunogenicity and protective efficacy of DNA vaccines encoding MAP0586c and MAP4308c of Mycobacterium avium subsp. paratuberculosis secretome.
Control of this disease is seriously hampered by the lack of adequate diagnostic tools, vaccines and therapies. In this study, we have evaluated the vaccine potential of two MAP proteins, i.e. MAP0586 c and ...
Indirect foot-and-mouth disease vaccine potency testing based on a serological alternative.
serum titres of primo-vaccinated cattle and protection against infection have been proposed, but none have been accepted by the European Pharmacopoeia (Ph.Eur.) due to the lack of statistical power and ...
