text: Ticks, blood-sucking parasites causin' diseases
  Ixodes ricinus, Europe's tick that pleases
  Tick-borne encephalitis, Lyme borreliosis
  Anaplasmosis, babesiosis, they leave you hopeless
  
  Immunization with recombinant proteins, the plan
  Interfere with tick feeding, stop pathogens, fam
  But tick antigens ain't been enough, they lack
  To achieve the goal, we gotta step back
  
  Focused on 11 genes, in silico seen
  Tick iron and heme metabolism, the theme
  Quantitative real-time PCR, we profiled
  Up-regulated proteins, tick physiology wild
  
  RNA interference, we put it to the test
  Score the importance, which genes are best
  Vaccination screens, the final show
  These new antigens, anti-tick vaccines will glow
