Table 4. PRFMLE analysis of selection pressures detected from interspecies and interstrain analysis of pil and opa genes of N. meningitidis and N. gonorrhoeae.
Gene | Species | Interpecies or interstrain analysis | γ (95% confidence interval) | Significance (p value) | Outcome |
---|---|---|---|---|---|
pil n = 219 | Interspecies | 3.44 ± 3.11 | 3.78 x 10−5 | Positive selection | |
N. meningitidis n = 71 | Interstrain | 2.47 ± 2.84 | 6.12 x 10−3 | Positive selection | |
N. gonorrhoeae n = 148 | Interstrain | 3.22 ± 3.52 | 7.73 x 10−4 | Positive selection | |
opa n = 86 | Interspecies | 3.44 ± 3.11 | 3.78 x 10−5 | Positive selection | |
N. meningitidis n = 17 | Interstrain | 2.68 ± 2.64 | 8.67 x 10−4 | Positive selection | |
N. gonorrhoeae n = 69 | Interstrain | 3.42 ± 3.36 | 1.40 x 10−4 | Positive selection |
