Genotoxicity evaluation of nanosized titanium dioxide, synthetic amorphous silica and multi-walled carbon nanotubes in human lymphocytes.
could be disclosed. In contrast, all forms of SAS analyzed in this study were unable to induce micronuclei. The present findings increase the weight of evidence towards a genotoxic effect of some forms of ...

Pulmonary artery haemorrhage in newborn calves following bluetongue virus serotype 8 experimental infections of pregnant heifers.
isolation facility (biosafety level 3) with a northern European outbreak strain of Bluetongue virus serotype 8 (BTV-8). The study was terminated 2 months after calving with necropsy of the dams and their ...
Effect of a DIVA vaccine with and without in-feed use of coated calcium-butyrate on transmission of Salmonella Typhimurium in pigs.
crucial, although additional control measures on-farm need to be considered. This study evaluated the effect of two potential control measures against the spread of Salmonella Typhimurium via a transmission ...
Development, validation and evaluation of added diagnostic value of a q(RT)-PCR for the detection of genotype A strains of small ruminant lentiviruses.
a useful complementary tool in SRLV diagnosis. The goal of this study was to develop and validate a quantitative PCR capable to detect a broad range of SRLV strains from genotype A, including strains ...
Development and validation of three Capripoxvirus real-time PCRs for parallel testing.
further Capripoxvirus diagnosis. It was therefore the purpose of this study to develop a triplet real-time PCR panel with similar high sensitivity/specificity and provide sufficient validation data ...

Suppl 2, p.51-62 (2013) Keywords: Animals Antibodies, Viral Belgium Chickens Disease Outbreaks Enzyme-Linked Immunosorbent Assay Follow-Up Studies Real-Time Polymerase Chain Reaction RNA, Viral Viremia ...
Effects of lung exposure to carbon nanotubes on female fertility and pregnancy. A study in mice.
We studied the effects of preconceptional exposure to multiwalled carbon nanotubes (MWCNT s): mature, female C57BL /6J mice were intratracheally instilled with 67μg NM-400 MWCNT, and the following day ...
Behavior of Yersinia enterocolitica in the presence of the bacterivorous Acanthamoeba castellanii.
epidemiology of human-pathogenic bacteria. In the present study, the interaction between Yersinia enterocolitica, an important food-borne pathogen, and the free-living amoeba Acanthamoeba castellanii was ...
Establishing mono-eukaryotic Histomonas meleagridis cultures from in vivo infection contaminated with Tetratrichomonas gallinarum and Blastocystis spp.
meleagridis. In addition the occurrence of different protozoa in the caeca of birds impedes, however, the isolation and propagation of H. meleagridis from field outbreaks. Therefore, in a kinetic study using ...
