Summary
Aspergillosis caused omphalitis in young commercial turkey poults. Aspergillus fumigatus was identified as the mycotic agent, a novel finding for this avian disease.
Area of Science:
- Veterinary Mycology
- Avian Pathology
Background:
- Omphalitis is a common condition in newly hatched poultry.
- Aspergillosis is a significant fungal disease affecting birds, particularly young ones.
Observation:
- Four cases of commercial turkey poults (3-9 days old) presented with omphalitis.
- Mycotic agents were isolated from the yolk sac in two cases and identified as Aspergillus fumigatus.
- In the remaining two cases, fungi in tissue sections were identified as Aspergillus sp. morphologically and confirmed by immunohistochemistry.
Findings:
- This study documents omphalitis associated with Aspergillus fumigatus in turkey poults for the first time.
- Aspergillus species were confirmed as the causative agents of omphalitis in these young birds.
Implications:
- Highlights the potential for Aspergillus fumigatus to cause omphalitis in turkey poults.
- Suggests the need for enhanced biosecurity and monitoring for fungal infections in poultry hatcheries.
- Contributes to the understanding of avian fungal diseases and their impact on poultry health.

01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:28Fungal Phylum Ascomycota
Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
