How to develop a controlled human infection model for Clostridioides difficile
which induces mild to moderate CDI symptoms but no severe CDI, determining optimal C. difficile inoculum dose and understanding the timing and duration of antibiotic pre-treatment in inducing ...
Genetically stable infectious Schmallenberg virus persists in foetal envelopes of pregnant ewes.
foetal envelopes is genetically stable since only a few mutations compared to the inoculum were found. This supports the hypothesis that persisting virus could start the infection of new hosts. Finally, ...
Experimental bluetongue virus superinfection in calves previously immunized with bluetongue virus serotype 8.
non-vaccinated group of calves were challenged twice (4 months apart) with the European BTV8 strain isolated during the 2006-2007 epidemics. Calves were then infected with a BTV1 inoculum which was found to be ...
Next-generation sequencing shows West Nile virus quasispecies diversification after a single passage in a carrion crow (Corvus corone) in vivo infection model.
introduced errors. The WNV populations in the wild crows showed significant diversification away from the inoculum virus quasispecies structure. By contrast, WNV populations in intracerebrally infected day-old ...
Full-Genome Sequencing of Four Bluetongue Virus Serotype 11 Viruses.
Serogroup Sheep Vaccination Viral Vaccines Abstract: Recently, a contamination incident was described in which the challenge inoculum used in a bluetongue virus serotype 8 (BTV-8) vaccination trial was ...
Experimental co-infections of calves with bluetongue virus serotypes 1 and 8.
the development of viraemia and high titres of anti- BTV-1 neutralizing antibodies proved that the inoculum was infectious and the detection protocols were efficient. Several hypotheses could explain ...
Experimental tuberculosis in the Wistar rat: a model for protective immunity and control of infection36574
of lung pathology in Mtb infected Wistar rats were dependent on the virulence of the strains and the size of the infecting inoculums. Bacillary growth control was associated with induction of T helper ...
A non-invasive intranasal inoculation technique using isoflurane anesthesia to infect the brain of mice with rabies virus.
virological outcome of infection with rabies virus (genotypes 1 and 5) upon administration of different inoculum volumes (25, 50 and 100μl) and different anesthetic regimens were examined. Administration of ...
Characterization of cultures enriched from acidic polycyclic aromatic hydrocarbon-contaminated soil for growth on pyrene at low pH.
Pollutants Abstract: Two polycyclic aromatic hydrocarbon (PAH)-contaminated soils of pH 2 were successfully used as inoculum to enrich cultures growing on phenanthrene and pyrene at different pHs, including pH ...
Ochratoxin A and citrinin loads in stored wheat grains: impact of grain dust and possible prediction using ergosterol measurement.
describes the results obtained using a lab model developed in order to assess the impact of grain dust incorporation for its direct contribution as a contaminant but also as an inoculum in stored wheat. ...
