In the first three months of age, both strains have a normal complement of rods and normal rod structure, but transducin α−/− mice have no rod-driven responses to light, while rod-driven activity of arrestin −/− mice can be suppressed by a single intense flash for hours.
The BpCyaA− strain behaved similarly to BpWT, both strains had a comparable low capability to be internalized by- and to survive in- MDDC (data not shown).
Both strains had a complementary substrate range.
Both strains have a single circular chromosome and possess no plasmid.
Although both strains had a similar immune-reactive profile, the MC lysate was significantly (p < 0.01) more immunoreactive than the MC lysate, indicating that the nontoxic strain was more allergenic than the toxic strain (see Supplemental Material, Figure S1).
Both strains had a more pronounced chondrocyte apoptosis, cartilage degradation, and subchondral bone changes in the medial than the lateral side of the tibia, and between strains, the changes were always greater and faster in DH than BS2.
Both strains had a transporter for D-methionine (operon metQIN), a general L-amino acid transporter (operon aapJQMP) and a branched-chain amino acid transporter (operon livKHMGF), critical for the biological N2-fixation process.
That study, and a proteomics comparison between Cyanothece 51142 and Cyanothece 7822 [ 14], indicated that both strains have a higher level of the nitrogenase, respiration and glycogen degradation enzymes in the dark than in the light.
Recently it was reported that two P. aeruginosa isolates from cystic fibrosis patients showed a wide phenotypic variability, even though both strains have a highly conserved genome sequence [ 35].
In addition, both strains have a copy of the fabF gene encoding for the 3-oxoacyl- acyl-carrier-protein) synthase II (PP_1916 (40.92% identity with fabB-KT gene) and PA2965 (42.3-oxoacyl- acyl-carrier-proteine).
