text: Yo, listen up, I got a tale to spin,
  'Bout a disease that's causing some serious sin.
  It's called Human Monocytic Ehrlichiosis, you see,
  Tick-borne sickness that can make you weak in the knee.
  
  Ehrlichia chaffeensis, the bacteria to blame,
  Intracellular, obligate, and it ain't no game.
  When you catch HME, flu-like symptoms arise,
  Fever, headache, malaise, and muscles in demise.
  
  But wait, there's more, it can take a turn for the worse,
  Severe form hits, it's like a deadly curse.
  Liver injury, organ failure, shock-like syndrome,
  It's a nightmare scenario, ain't no place for you to roam.
  
  Macrophages and monocytes, they're the target cells,
  Ehrlichia ain't picky, it invades like a spell.
  Hepatocytes and endothelial cells, they're not spared,
  This bacterium's reach, man, it's everywhere.
  
  Now let's dive deep, talk about polarization,
  Macrophages split, it's a critical situation.
  M1 or M2, these phenotypes matter,
  They determine the severity, the infection's chatter.
  
  We gotta understand the mechanisms at play,
  How these polarizations go either way.
  The outcome of ehrlichiosis hangs in the balance,
  So let's unravel the secrets, no time for silence.
