WHAT IS ASPERGILLUS?
By Hannes Hattingh
Aspergillus (commonly known as ‘aspi’) is a widely occurring fungus which is frequently found as a pathogenic organism in the chicken industry. It can also be hazardous to both humans and animals.
Birds are generally resistant to the harmful effects of this fungus, but where they are found in large numbers, they become highly susceptible to infection caused by the aspergillus mould.

ASPERGILLUS FUMIGATUS
Aspergillus, in particular, is one of the main respiratory pathogens in the industry and most commonly found in hatcheries and chicken houses. If uncontrolled, it can become responsible for high mortalities with subsequent large financial losses to the farmer.
It is a common, naturally occurring fungus that can crop up anywhere, depending on suitable ambient conditions, and is present in the soil, wild birds, grass (hay), and anything used as bedding litter.
Aspergillus is a vigorous grower and will proliferate rapidly in any suitable organic material. This results in massive amounts of spores (conidia) that are easily carried by wind or spread by dirt. In chickens (and also humans), these spores can be inhaled and become deposited in the respiratory tract, where they grow and cause aspergillosis.
WHAT IS THE IMPACT OF ASPERGILLOSIS ON CHICKS AND EMBRYOS?
- Increased embryo mortality results in decreased hatchability.
- Early chick mortality of between 20% and 50%.
- Reduced viability due to immunosuppression.
SAY NO to Aspergillus contamination.
SAY YES to healthy eggs, birds and more profit.
