Razavi et al. [20], in contrast to ASOPRS group findings, concluded that there are significant differences in the isolates between acute and chronic dacryocystitis, although the study did not show much difference, and the sample size of acute cases was only 12 patients.
Unfortunately, H1N1 isolates between 2007 and 2008 were not included in this study.
All DR M. tuberculosis complex isolates between 1994 and 2008 were studied.
A selection of 658 isolates from hospital laboratories that submitted 30 or more isolates between January and October was included.
Oseltamivir resistance associated mutation at position 274 of NA was absent n all H3N2 isolates between 2006 and 2009 and H1 isolates from 2006.
The distribution of the local isolates between two genovars based on the A to G modification in the rrs gene places B. persica in a unique phylogenic position.
A feature of HIV and FIV infection is the continually increasing divergence among viral isolates between different individuals, as well as within the same individuals.
Discordant alleles were found in 24 isolates between isolate from day 0 (wild-type NYD) and isolate from day of recurrence (13 single-mutant alleles YYD, 8 single-mutant alleles NFD and 3 double-mutant alleles YFD).
In the absence of geographical barriers and given the relatively short distances involved (Figure 3), the spread or exchange of Y. pestis isolates between these areas is not unlikely.
However, we did not observe the significant difference in the clustering proportion among MDR-TB isolates between two counties, suggesting that without routine bacteriologic-based diagnosis and drug susceptibility testing and without regulated treatment for drug-resistant TB, DOTS itself might not be able to prevent the risk of community-level MDR-TB transmission.
In any case, of pivotal importance for the evaluation of the vaccination strategies is the fact that, due to this early viral activity in São Paulo, there was not a significant difference in the overall timing of viral activity (as measured by the vector means of the distribution of the isolates) between both cities.
