Cryptosporidium parvum - Coggle Diagram

- - - - Sporozoites differentiate into Trophozoites
      - Undergo asexual multiplication to produce Type I meronts
      - Type I meront undergoes schizogony
      - Releases 8 merozoites
      - Invade adjacent enterocytes & undergo repeated Schizogony to produce Type II meronts
      - Four merozoites are released
    - - Microgamont releases 16 microgametes
      - 1 macrogamete is produced from each macrogamont
      - Merozoites transform into microgamont & macrogamont
    - - Fertilization - Microgamete + Macrogamete = Zygote
      - 80 % of zygote transform to highly resistant double layered thick walled oocyst
      - 20% transform into single layered thin walled oocyst
      - Oocysts undergo sporogony to produce 4 sporozoites
      - Sporulated oocysts excreted in faeces
      - Thick walled oocyst infects new hosts
      - Thin walled oocysts infect the same host ( Autoinfection )
    - - period from time of ingestion of oocyst to completion of lifecycle
      - 4 - 22 days
    - - 4 slender crescent shaped sporozoites released
      - Pancreatic enzymes & bile salts heps
    - - Sporozoites invade epithelial cells of small intestine
