text: Yo, check it out, here's the lowdown,
  128 bovine, 134 humans, that's how it goes.
  Group B streptococci, serotyped conventionally,
  Keepin' it real, that's our methodology.
  
  Among the bovine cultures, listen up, y'all,
  Type antigen X, 60 strong, standin' tall.
  And for the human cultures, don't you forget,
  Type antigen R, 53 reppin', no regret.
  
  Type antigens X and R, they got a connection,
  To the growth pattern, payin' close attention.
  In fluid media, these bacteria do their thing,
  Formin' long chains, granular sediment they bring.
  
  With a clear supernatant, they make it known,
  Type X and R, they hold the throne.
  But that ain't all, there's more to tell,
  Nontypeable cultures, they rock as well.
  
  Long chains and granular, they're the main deal,
  In soft agar, compact colonies they reveal.
  Reactin' positive in the salt aggregation test,
  X and R on the surface, they pass the best.
  
  These properties, yo, they got a story to tell,
  Surface charges of X and R, they ring the bell.
  Possibly linked to bacterial pathogenicity,
  X and R-positive cultures, they got the ability.
  
  So there you have it, the facts are laid out,
  Group B streptococci, they know what they're about.
  Type X and R, they got the style,
  In the world of bacteria, they're toppin' the pile.
