Abstract
Aim: The current study was conducted to assess fungal contamination of table eggs sold in Khartoum State, Sudan.
Study Design: This descriptive evaluation study was conducted at Mycology Department, Central Veterinary Research Laboratory, Khartoum State, Sudan over 6-month duration.
Methodology: Egg samples (shell and egg contents) were examined directly using lacto phenol cotton blue slide mount technique. The culture of samples in Sabouraud Dextrose Agar (SDA) supplemented with antibiotic was carried out. Identification of the isolates was based on their macro and microscopic morphological characteristics.
Results: Fungal colony was obviously seen on egg membrane and revealed as Aspergillus flavus on direct microscopic examination. Whereas A. flavus and A. niger hyphae were detected on culture from both egg shell and contents.
Conclusion: Isolation of A. flavus and A. niger from both egg shell and content by conventional method. The obtained results report the occurrence of A. flavus in table eggs sold in Khartoum state, Sudan.
Keywords: Egg shell, egg contents, Aspergillus flavus, conventional methods
