Epistasis01:39

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Summary

A severe outbreak of aspergillosis, a fungal infection, affected young ostriches in Israel. Aspergillus niger and Aspergillus flavus contamination in the hatchery likely caused this brooder-borne disease.

Area of Science:

  • Veterinary Mycology
  • Avian Pathology
  • Ostrich Farming

Background:

  • Aspergillosis is a significant fungal disease affecting poultry.
  • Young birds are particularly susceptible to respiratory fungal infections.

Purpose of the Study:

  • To document a severe case of aspergillosis in ostriches.
  • To identify the causative agents and potential sources of infection.

Main Methods:

  • Clinical examination of affected ostriches.
  • Necropsy and isolation of fungal agents from lung tissues.
  • Hatchery environmental sampling for fungal contamination.

Main Results:

  • Isolation of Aspergillus niger and Aspergillus flavus from the lungs of affected ostriches.

  • Heavy contamination of the hatchery environment with both Aspergillus species.
  • Identification of a likely brooder-borne source of infection.

    • Conclusions:

    • Aspergillosis poses a severe threat to young ostrich flocks.
    • Hatchery contamination is a critical risk factor for brooder-borne aspergillosis in ostriches.
    • Effective hatchery hygiene is crucial for preventing avian aspergillosis outbreaks.
