Genetic polymorphism of Aspergillus fumigatus in clinical samples from patients with invasive aspergillosis: investigation using multiple typing methods34009
fumigatus should be considered separately for each of these geographic areas. This study demonstrates the usefulness of combining several typing methods in reaching an understanding of the epidemiology of A. ...
Le protocole sur la biosécurité: test de crédibilité pour l'avenir de la Convention sur la diversité biologique?
protocol and the relationship between the protocol and the World Trade Organisation.Even if, because of its specificity, the protocol can be considered as a “curiosity” compared to other topics covered under ...
Interaction between turkey monocytes and avian Chlamydia psittaci in the presence of Mycoplasma sp.: the importance of nitric oxide1192
the NO production and reversed the antichlamydial activity of the M. hyorhinis co-inoculated turkey monocytes. These results imply two considerations. First, as chlamydiae are obligate intracellular ...
A review of the importance of cryptosporidiosis in farm animals.
diarrhoea syndrome of calves, lambs and goat kids, causing considerable direct and indirect economic losses. Avian cryptosporidiosis is an emerging health problem in poultry, associated with respiratory ...
Classical swine fever virus is genetically stable in vitro and in vivo.
demonstrates that classical swine fever virus is genetically stable. Hence, even minor mutations can be considered significant in molecular epidemiological studies. Health Topics: Animal health Category: A1 ...
Genetic multilocus studies of different strains of Cryptococcus neoformans: taxonomy and genetic structure232334008
and serotype. The second analysis considered three serotype groups (B, C, and A plus D plus A/D), proving that serotypes A, D, and A/D are closely related. MLEE is a useful epidemiological tool for ...
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 ...
Detection of foot-and-mouth disease by reverse transcription polymerase chain reaction and virus isolation in contact sheep without clinical signs of foot-and-mouth disease.
sentinel pigs. This indicates that serologically positive contact sheep without clinical signs may be considered as a danger for the transmission of FMDV. Health Topics: Animal health Category: A1 FOS ...
Reduction of singleton reactors against swine vesicular disease virus by a combination of virus neutralisation test, monoclonal antibody-based competitive ELISA and isotype specific ELISA.
number of animals finally considered as singleton reactors can be reduced considerably by performing three different serological tests (virus neutralisation test, monoclonal antibody-based competitive ...
CD57, a marker for B-cell activation and splenic ellipsoid-associated reticular cells of the chicken.
B-cell marker). Thus, CD57 should be considered as a B-cell activation marker, rather than as a marker for bursal B-cells; it is also a valuable marker for the immunohistochemical study of ...
