Interestingly, when a gene exhibited variations in several strains, the amino acid changes they trigger were found to be partly conserved.
For several strains, the transformant displayed decreased carbapenem resistance compared with a parental strain (e.g., 1100192-TF), suggesting that additional mechanisms (e.g., AmpC and ESBL) present in the parental strain and not carried on the NDM-encoding plasmid may have contributed to the initial carbapenem-resistant Enterobacteriaceae phenotype observed.
During the 1960s several strains of the malarial parasite Plasmodium falciparum developed resistance to the synthetic drugs, particularly the highly valued chloroquine.
The available data revealed that these bacteria belong primarily to the Proteobacteria, with several strains from the sphingomonads, and one from each of the Methylobacillus and Paucibacter genera.
During the 1960s, several strains of the malarial parasite Plasmodium falciparum developed resistance to some synthetic drugs, particularly chloroquine.
All Sudan RVFV strains from the 2007 outbreak, and several strains from the 2010 RVF outbreak, were embedded into the Kenya-2 sublineage; however, 2 strains from 2010 were included in the Kenya-1 sublineage.
When several strains from the same species encoded the same SDH gene, only one representative strain was included, the strain from the first sequenced genome.
When several strains from the same species encoded the same cluster only a representative strain was included, with the strain from the first sequenced genome chosen.
This suggested that a 16S rRNA recombination occurred in this species that may be facilitated by the coexistence of several strains in the blood of cats (27 ).
The reactions against several strains of the pandemic virus were similar, reflecting high titers against pandemic (H1N1) 2009 virus but also cross-reactions with hyperimmune serum samples of all swine influenza A virus H1N1 vaccine strains (Appendix Table).
Although the picture becomes complex when several strains of the same species co-occur, strain-specific contributions to the overall protein pool can still be resolved.
