39
Q

Type of photosensitation that commonly occur in cattle due to aberrant pigment metabolism ?
a. Type I
b. Type II
c. Type III
d. Type IV

A

Type II

  • Primary photosensitation - Type I: occurs when the photodynamic agent is either ingested, injected, or absorbed through the skin.
    Photodynamic agent ->absorbed in skin or GIT - >skin(native form)
  • Defective or aberrant pigment formation - Type II
    due to aberrant pigment metabolism is known to occur in both cattle and cats. Photosensitizing porphyrin agents are endogenous pigments that arise from
    inherited or acquired defective functions of enzymes involved in heme synthesis (heme oxygenase)
  • Secondary (Hepatogenous) – Type III: most frequent type of photosensitivity observed in livestock. Photosensitizing agent, phylloerythrin (a porphyrin),
    accumulates in plasma because of impaired hepatobiliary excretion.
  • Idiopathic – Type IV: Photosensitivity where the pathogenesis is unknown or the photodynamic agent is not dentified is classified as type IV
