Interaction between turkey monocytes and avian Chlamydia psittaci in the presence of Mycoplasma sp.: the importance of nitric oxide1192
might take place in vivo. Moreover, it was shown that avian M. gallisepticum strains were also able to induce NO in turkey monocytes. Considering the high prevalence of both C. psittaci and Mycoplasma sp. ...
A review of the importance of cryptosporidiosis in farm animals.
cryptosporidiosis in each of the hosts is given. Cryptosporidiosis seems to be mainly a problem in neonatal ruminants. Cryptosporidium parvum is considered to be an important agent in the aetiology of the neonatal ...
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.
are considered as singleton reactors. False positive serological results for an epizootic disease, like SVD, in a non-vaccinated population or in imported animals are of great concern to international ...
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 ...
Concepts for a model of good medical laboratory services127
published. Although these standards are found useful to some extent, they are considered to be insufficient in several areas important for medical laboratories particularly in the pre- and post-examinational ...
Isolation of yeasts from bovine milk in Belgium
recovered from normal milk. Among the three species, only one i.e. Candida kefyr is able to grow above 40 degrees C and from there can be considered as potentially pathogenic, even if bacterial association is ...
