CD4+ T cells contain Mycobacterium tuberculosis infection in the absence of CD8+ T cells in mice vaccinated with DNA encoding Ag85A.
cytokines similar to wild-type mice. Although beta2m-/- mice were more susceptible to M. tuberculosis infection, following vaccination they efficiently controlled bacterial replication in spleen and lungs ...
Trends in gonorrhoea in nine western European countries, 1991-6. European Study Group.
laboratory reports or data from more extensive sexually transmitted infection surveillance networks. RESULTS: 7192 episodes of gonorrhoea were recorded at 38 sentinel sites in nine countries between 1991 and ...
Immunogenicity and protective efficacy of DNA vaccines encoding secreted and non-secreted forms of Mycobacterium tuberculosis Ag85A.
differing potencies, as the more immunogenic DNA construct encoding a secreted form of Ag85A was protective, whereas the less immunogenic DNA construct encoding a non-secreted form of Ag85A was not. Health ...
Highly sensitive detection of swine vesicular disease virus based on a single tube RT-PCR system and DIG-ELISA detection.
Abstract: A highly sensitive detection of swine vesicular disease virus (SVDV) based on a single tube RT- PCR system and digoxigenin (DIG)- PCR- ELISA detection was developed. Using a one tube RT- PCR system ...
External quality assessment (EQA) of Belgian clinical laboratories. The telematics paradigm129
information systems has recently become cheaper and more powerful. It is therefore timely to consider the effects of the introduction of such techniques in external quality assessment (EQA) schemes on both ...
Widespread occurrence of the micro-organism Wolbachia in ants.
Abstract: For more than 20 years, sex allocation in hymenopteran societies has been a major topic in insect sociobiology. A recurring idea was that relatedness asymmetrics arising from their haplodiploid sex ...
Role of the humoral immune system in Salmonella enteritidis phage type four infection in chickens.
weeks pi in controls and were absent in bursectomized chickens. These findings indicate that elimination of S. enteritidis partly depends on humoral immunity. The intestinal humoral response appeared more ...
CD57, a marker for B-cell activation and splenic ellipsoid-associated reticular cells of the chicken.
the activation state of the immune system. Moreover, CD57 is expressed by bursal lymphocytes (90% or more) but not by B-cells of the peripheral blood. More interestingly, we have been able to ...
Immunogenicity and efficacy of a tuberculosis DNA vaccine encoding the components of the secreted antigen 85 complex.
lungs from B6 mice, subsequently challenged. Therefore, this technique may be useful for the definition of protective antigens of M. tuberculosis and the development of a more effective ...
Methicillin-resistant Staphylococcus aureus epidemiology and control in Belgian hospitals, 1991 to 1995. Groupement pour le Dépistage, l'Etude et la Prévention des Infections Hospitalières.
42% to 57% of hospitals. In 1995, 88% of participants detected MRSA strains by disk diffusion tests, with little improvement in standardization since 1991. More centers employed the oxacillin agar ...
