Virulent contamination injected in your veins
Sympthomatology is evident
Mordicant contagion of the sanguineous cruor
Pathogenesis out break
Arthritic members swell as your body shivers
Semiparalized by pain
Pustules release a chorous secretion
Of gangrenous purulence

Pernicious plague... Of swarming virulence
Created to infest... There's no defence
[ Lyrics from: http://www.lyricsfreak.com/h/haemorrhage/pernicious+dyseptic+inoculation_20579962.html ]
Infestation - boiling in your scabs
Incubation - engendred in the lad
Aftermath of septicaemia
Suppuration - seeps out of the pores
Inoculation - infected to the gore

Infectious carbuncles macerated by sanies
Blisters expanded on your face
Microscopic terrorist in your organism
Septic havoc in your flesh
Nausea convulse your stomach(pre-emetic retch)
A black vomit is discharged
Effortless defecation of viscid faecal grume
Fetid dysenteric scum

Pernicious plague... Of swarming virulence
Created to infest... There's no defence
