A positive antibody
titer means that your cat's immune system is producing antibodies to a pathogen, and if enough antibody is produced, this may provide protection from infection.
*
Titer use is acceptable for distemper, parvo, adenovirus.
In one study, only 10 out of 19 bacteriophages survived after storage for 10 years without a fall in bacteriophage
titer, but the impact of storage in this study was not uniform (Ackermann et al., 2004).
Post vaccination H7N3 virus antibody response of chicks in Group C vaccinated with H7N3 (Otto-flu): On day 07 post-vaccination, an HI
titer of 1: 2 was recorded in serum sample of one chick and a
titer of 1: 4 was observed in each serum sample of 07 chicks; a
titer of 1: 8 in each serum sample of 11 birds and a
titer of 1: 16 was recorded in serum sample of one bird.
A single Anti Streptolysin O
titer was obtained from all patients at admission.
Group F shows the highest HI antibody
titer (294.1) which was vaccinated with ND only.The lowest HI antibody
titer was recorded in group E (32.0).
With the exception of hepatitis B among children adopted from Korea and mumps among all children, the percentages of positive antibody
titers were similar to rates that have been reported in U.S.
However, immunization of such subjects should be followed by periodic RVNA
titer determination for sake of safety (Burr and Snodgrass, 2004; NACI, 2005).
We compared HI
titers between mothers and cord sera; 58% had the same
titers, 31% of cord sera had higher
titers, and 11% of cord sera had lower
titers.
Virus
titers were extrapolated from RT-PCR results by comparison with a standard curve generated from serial dilutions of a VEEV stock quantified by plaque assay.
Given the equivocal HeV
titers in the 2 bats, these results are likely false positives.
The highest
titer (3.5 x [10.sup.5] IU/mL) was obtained with the combination of QT6/ACE2 cells and MLV(SARS), so this system was employed for all subsequent assays.
