Summary

Ichthyosis, a rare skin condition, was identified in two Italian Chianina calves. This study details ichthyosis fetalis and ichthyosis congenita, highlighting genetic defect suspicions.

Area of Science:

  • Veterinary Dermatology
  • Animal Genetics
  • Congenital Disorders

Background:

  • Ichthyosis is a group of genetic skin disorders characterized by dry, thickened, and scaly skin.
  • This condition can affect various animal species, impacting their health and welfare.
  • Documenting new occurrences in specific breeds is crucial for understanding disease prevalence and genetics.

Observation:

  • Two Italian Chianina calves presented with congenital ichthyosis, one with ichthyosis fetalis and the other with ichthyosis congenita.
  • Clinical signs included diffuse cutaneous thickening, hypotrichosis, alopecia, delayed coat color change, stiff movement, and growth retardation in the first calf.
  • The second calf exhibited hyperkeratotic plates, deep fissures, eclabium, and ectropion.

Findings:

  • Histopathological examination revealed diffuse lamellar orthokeratotic hyperkeratosis in both affected calves.
  • The clinical presentations varied, suggesting potentially different subtypes or severities of ichthyosis.
  • A common ancestor for the sires of the affected calves pointed towards a suspected underlying genetic defect.

    • Implications:

    • This is the first report of ichthyosis in Italian Chianina calves, expanding the known breed susceptibility.
    • The findings support the hypothesis of a genetic etiology for ichthyosis in this breed.
    • Further genetic investigations are warranted to identify the specific mutation and enable potential breeding strategies.
