For example, in 2003 FDA rejected the use of the most appropriate H3N2 strain, A/Fujian/411/ 2002, and instead again used the same strain as in the 2002 formulation.
Despite the low prevalence of Beijing strains in our area, we found 2 patients infected by the same strain (Figure), which suggests transmission between them.
On the basis of these data, we assume that the dog became colonized with the same strain as its owner through contact, and that either the dog or the baby or an unknown source within the nursing home reinfected the nurse.
Three of the strains have been sequenced more than once and differ by as many as 8 nt within the same strain. Between sequences, the number of nucleotide differences ranges from only 1 nt difference between A/Chile/6/1957 and A/Davis/1/1957 to 12 differences between one of the A/Japan/305/1957 sequences and one of the A/Singapore/1/1957 sequences.
Sequences from different passages of the same strain were sometimes as different from each other as they were from other strains (29), suggesting that sequence heterogeneity observed was the result of culture adaptation, making it impossible to determine how homogeneous the pandemic viruses actually were.
Aeromonas also occurs in groundwater (6,10,11), and in a single well, the same strain can persist for years (11).
Three of those groups included only isolates derived from the same composite water sample, suggesting multiple isolations of the same strain. Analyzing all pairwise comparisons among the 65 isolates, the median similarity was 59% (range 16% to 100%, n=2,080).
tuberculosis adds important pieces to the construction of such a transmission puzzle; persons who harbor the same strain of M.
"We have the same strains as Jackson and Charles River Japan, but we have a better record for supplying mice quickly and with less risk to customers in Japan." And, at least for the next ten years, Abe sees a strong market.
Kolenbrander also sees evidence of competition, similar to situations in other branches of ecology, among bacteria that coaggregate with the same strains.
The patterns obtained by AP-PCR and PFGE (Xba I- and Spe I-digests) were almost indistinguishable; however, when DNA of the same strains was analyzed by PFGE after digestion with Avr II, differences were detected.
