The initial DST is performed on the first positive mycobacterial culture for all cases; a follow-up test is repeated if treatment failure or developed drug resistance is suspected on a specimen collected at least 30 days after the initial specimen.
But other tests on similar specimens did not, prompting some virologists to question whether the initial specimen was contaminated at a lab where earlier tests for SARS had been conducted.
Pole figure analysis indicates that compared with the initial specimen, textures below 930 °C are weaker, while at 930 °C they are stronger.
The initial specimen for one patient (patient 5, Table 1) was tested with a slightly modified IgM antibody assay at a commercial laboratory (12 ).
At the NPRL, the initial fecal specimen was extracted according to recommended procedures (5 ) and incubated with 4 continuous mammalian cell lines: L20B, RD-A, Hep2 Cincinnati, and human embryonic lung.
The present location of this initial specimen is uncertain; reportedly stored at the Hudson Bay Museum, it could not be located in 1915.
Of the 60 persons classified as uninfected whose repeat WB/IFA test result was negative, 57 (95%) had EIAs performed at the local laboratory on the initial confirmatory specimen, and of these, 1 (2%) was reactive; 47 (78%) had EIAs performed on the repeat confirmatory specimen at the local laboratory, and of these, 1 (2%) was repeatedly reactive.
aRespiratory specimen during the 30 days after initial specimen for bacteriologic test was taken.
Post-liquefaction strengths were measured by reconsolidating the specimens at the initial effective confining stress and performing consolidated undrained triaxial tests.
At the initial staffing levels, only 30 40 specimens could be tested per day; in addition, the laboratory was a full day's drive from many outlying areas, and counties had few vehicles for transporting laboratory specimens or patients.
