  1. .... prausnitzii) are likely the results of more plastic s subject to recombination and lateral gene exchange. This has been described in a few specific cases such as oral neisseriae (Donati et al. 2016), but the relative ease withwhich thousands ofmetas can nowbe obtained compared to isolate (Browne et al. 2016...
  2. ...was estimated to be 2.91 (similar to an earlier estimate of 2.41 based on 13 s) (Didelot et al. 2009), which is an intermediate level compared to the extremes of recombinogenic speciesNeisseria meningitidis and clonal Staphylococcus aureus (r/m of 13.6 and 0.2, respectively) (Didelot et al. 2009; Vos...
  3. ...within human populations in Neisseria meningitidis ( Linz et al. 2000 ; Zhu et al. 2001 ), but in general the role of recombination in the evolution of other phenotypic adaptations remains unclear, and its extent has not been quantified at the genomic level. Indeed, it has even been suggested...
  4. ...naturally transformable species such as Streptococcus pneumoniae and Neisseria meningitidis have very high rates of homologous recombination (Dubnau 1999). In other species such as Salmonella enterica, horizontal exchange is generally restricted to the movement of MGEs (Harris et al. 2010). Although HGT...
  5. ...( Maynard Smith et al. 1993 ; Feil and Spratt 2001 ). The frequency of recombination is extremely variable, resulting in population structures that range from panmixia in Helicobacter pylori ( Falush et al. 2001 ; Linz et al. 2007 ) and Neisseria meningitidis ( Feil et al. 2001 ) to absolute clonality...
  6. ...-wide collections listed in Table 1 (Fig. 4; Supplemental Fig. S8). Species known to exchange sequence through homologous recombination at similar frequencies to S. pneumoniae, such as Neisseria meningitidis (Fig. 4), exhibited a similar distribution of pairwise genetic distances. The group of within...
  7. ...-locus sequence typing (MLST), first developed to characterize (‘‘type’’) strains of Neisseria meningitidis and other pathogens (Maiden et al. 1998), has now come to be the dominant method for analysis of population structure with prokaryotes of all kinds (in which context it is more commonly called MLSA...
  8. ...a rectal swab of a 49-yr-old MSM who was HIV positive and Hepatitis C negative. He attended a London Genital and Urinary Medicine (GUM) clinic in January 2006 showing clinical signs of proctitis. The rectal sample tested positive for C. trachomatis (negative for Neisseria gonorrhoeae ) using a conventional...
  9. ...,020 were required for the of Neisseria meningitidis ( Tettelin et al. 2000 ), which is of a similar size. Diagnostic sequence allowed us to identify all L. lactis genes that encode proteins sufficiently similar to those present in the databases. However, the elevated error rate, estimated to be ∼1%, did...
  10. .... 2000 ), and respiratory viruses ( Raza et al. 1991 ); yet secretor subjects also display advantages compared to nonsecretors, such as lower susceptibility to urinary tract and Candida infections, and increased protection against Neisseria meningitis and Streptococcus ( Haverkorn and Goslings 1969...
