Parasite distribution and associated immune response during the acute phase of Toxoplasma gondii infection in sheep22

investigated: the parasite’s entry site, the subsequent distribution of the parasite and the host-immune response. RESULTS: Parasite DNA was already detected in the cranial small intestinal mucosa the first days ...

Parasite distribution and associated immune response during the acute phase of Toxoplasma gondii infection in sheep.

the detection limit three weeks after infection. This coincides with an increase in parastic-specific serum IgG1 and IgG2 and a decrease of the antigen-specific IFN-gamma response in PP, PBMC and ...

Validation of a sensitive DNA walking strategy to characterise unauthorised GMOs using model food matrices mimicking common rice products

on model food matrices mimicking common rice products, have allowed to determine the limit of detection as well as the potential effects of food mixture and processing. This detection system allows the ...

Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.

0.25ngg(-1) for all dyes, with a signal-to-noise ratio of at least 10/1. This is at least 5 to 10 times lower than previous published methods. Limits of detection were all <0.1ngg(-1). Precision and trueness ...

Development, validation and evaluation of added diagnostic value of a q(RT)-PCR for the detection of genotype A strains of small ruminant lentiviruses.

circulating in Belgium. The developed q(RT)- PCR targets a region of the gag gene and showed to be highly sensitive and specific with a limit of detection of 6 DNA and 40 RNA copies/reaction respectively. SRLV ...

Effect of saliva stabilisers on detection of porcine reproductive and respiratory syndrome virus in oral fluid by quantitative reverse transcriptase real-time PCR.

presence of PRRSV RNA by qRT- PCR. PRRSV RNA could be detected in oral fluid using all extraction-amplification combinations, but the limit of detection varied amongst different combinations. Storage ...
