text: Yo, check it out, here's the scoop,
  Thirty 5-month-old red-legged partridges, a group so cute,
  Rearing in battery, divided into five,
  Group A with 4 birds, B with 14, yo, they thrive!
  
  Group C, D, and E, each got 4 as well,
  Inoculated with Toxoplasma gondii, let me tell,
  Ten, fifty, ten to the power of two,
  Ten to the power of three, and ten to the power of four, oocysts they drew.
  
  Every 3-7 days, blood samples were drawn,
  Serologic response, let's see what's goin' on,
  Modified agglutination test (MAT), latex agglutination test (LAT),
  Measure the antibodies, see if they're intact.
  
  At 44, 58, 65, and 72 days, birds were slain,
  From 72 DAI, weekly intervals, they couldn't sustain,
  The experiment went on, till 100 DAI,
  The last partridges sacrificed, no lie.
  
  MAT was the test, sensitive and specific,
  Detectin' T. gondii antibodies, no gimmick,
  On 7 DAI, first positive titers did show,
  But LAT took 'til 13 DAI, yo, now you know.
  
  MAT titers on 7 DAI, higher they were,
  For partridges with big oocyst dose, that's for sure,
  10(3) and 10(4) oocysts, they were the ones,
  While 10, 50, and 10(2) oocysts lagged behind, sons.
  
  All surviving birds, yo, they developed a response,
  To T. gondii, antibodies in abundance,
  MAT showed titers from 512 to 32,768,
  On 13-17 DAI, positive titers, it ain't too late.
  
  And those positive titers, they stayed around,
  At least till 100 DAI, they were still found,
  But LAT, well, it didn't show much,
  Even in high-dose birds, yo, it didn't clutch.
