DNA ploidy and nuclear morphometric variables for the evaluation of melanocytic tumors in dogs and cats.
The DNA content (index), nuclear diameter, ploidy balance, proliferation index, hyperploidy, and growth fraction (Ki67) were measured. Using 1-way ANOVA and a Pearson correlation test, the relationships ...
Infectious bursal disease (Gumboro disease).
true incidence of different types is difficult to determine. Moreover, the infection, when not fatal, leads to a degree of immunosuppression which is often difficult to measure. Finally, the control ...
Tuberculosis DNA vaccine encoding Ag85A is immunogenic and protective when administered by intramuscular needle injection but not by epidermal gene gun bombardment.
M. tuberculosis challenge, as measured by reduced numbers of CFU in spleen and lungs, compared to animals vaccinated with control DNA. Gene gun immunization was not effective in either BALB /c or C57BL ...
Production of antibodies against chicken interferon-gamma: demonstration of neutralizing activity and development of a quantitative ELISA.
whereas mAb 1E12 recognized a distant epitope. Moreover, this latter mAb was able to highly neutralize the biological activities of both recombinant and natural ChIFN-gamma as measured by inhibition of ...
What is the optimal regimen for BCG intravesical therapy? Are six weekly instillations necessary?
before, every week during the BCG instillations and at 3 and 6 months follow-up in 9 patients with superficial bladder cancer treated with 6 weekly BCG instillations. Lymphoproliferation was measured by ...
Cloning of the gene encoding a 22-kilodalton cell surface antigen of Mycobacterium bovis BCG and analysis of its potential for DNA vaccination against tuberculosis.
measured by interleukin-2 and gamma interferon secretion, was only modest, and no protection against intravenous M. tuberculosis challenge was observed in any of the three mouse strains tested. Therefore, ...
Dietary L-carnitine supplementation increases antigen-specific immunoglobulin G production in broiler chickens.
either reduced immediately to 20 degrees, or gradually to 22 degrees at 36 d of age. Antigen-specific immunoglobulin (Ig)M, IgG, IgA and total Ig responses were measured following two immunizations with ...

Development of immunocompetence of broiler chickens.
immunised in ovo (ED16 and ED18) and at 1, 7 and 12 days of age and subsequent BSA-specific immunoglobulin (Ig) M and IgG responses were measured up to 10 days postimmunisation (DPI). No major differences ...
Effects of inhalation of dust and endotoxin on respiratory tracts of pigs.
6 days to feed flour dust (1 to 15 mg/m3) and dustborne endotoxins (50 to 2,500 ng/m3). Effects were evaluated by measuring albumin concentration, lactate dehydrogenase (LDH) activity, cell composition of ...
