Trypan blue stain was co-administered with the cells to localize the site of the inoculum.
Symptoms developed rapidly on roots of Bd21 with amber-brown discolouration present at the site of contact with the inoculum by 24 hpi.
With its early detection and prompt removal of infected hosts, the Oregon SOD eradication program has produced a landscape distribution of disease resulting predominantly from the long distance (100 m to 4 km) dispersal of inoculum between sites.
The mineralization of benzene with sulphate as electron acceptor was quantified in sand- and lava granules-filled columns or in situ microcosms, using sulfidic groundwater of the site as inoculum (Vogt et al. 2007).
For determination of the immune response and histological analyses, the technique was modified to allow easier localizing of the site of infection: 50 µl Candida inoculum containing 1×105 cells was placed onto sterile nylon membrane filters (0.45 µm pore size, 13 mm in diameter, cut in half; Carl Roth GmbH, Karlsruhe, Germany) on sterile Whatman® blotting paper (GE Healthcare, München, Germany).
Differences between sites and seasons in the relative amounts of inoculum detected do not, however, provide a reliable guide to the relative amounts of take-all that can be expected to develop on the roots of the following crops.
The inability to propagate an HRV A2 virus could be due to many factors including the age, storage, site of origin and amount of the inoculum, its handling during processing, how long after symptoms appear before sampling occurs and the culture conditions used.
The signal values from the remaining positive sites were averaged for each inoculum and plotted as a function of inoculum CFU (obtained from the plated inoculum titer).
These factors are 1) amount or regions of cattle brain tissue taken for inoculum preparation, 2) physicochemical treatment during inoculum preparation (e.g., temperature, homogenization buffer), 3) the precise site of mouse inoculation, 4) the infectious titer of the inoculum, and 5) others unknown mouse factor affecting prion propagation and disease evolution.
Two treatments were evaluated: (bee-vectored inoculum [1.37 × 1010 conidia/g of inoculum] and a control [bees but no inoculum]).
