• caseous necrosis
  16 September 2005

  Caseous necrosis is a distinctive form of coagulative necrosis, is encountered most often in foci of tuberculous infection.
  The term caseous is derived from the cheesy white gross appearance of the area of necrosis.
  On microscopic examination, the necrotic focus appears as amorphous granular debris seemingly composed of fragmented, coagulated cells and amorphous granular debris enclosed within a distinctive inflammatory border known as a granulomatous reaction. Unlike coagulative (...)

• helminths
  24 November 2004

  Parasitic worms are highly differentiated multicellular organisms. Their life cycles are complex; most alternate between sexual reproduction in the definitive host and asexual multiplication in an intermediary host or vector.
  Thus, depending on parasite species, humans may harbor either adult worms (e.g., Ascarus lumbricoides) or immature stages (e.g., Toxocara canis) or asexual larval forms (e.g., Echinococcus species).
  Once adult worms take up residence in humans, they do not multiply (...)
