Aspergillosis<\/h4>\n
Fungi and yeasts may affect poultry by direct infection or via infection of feedstuffs, which may also alter the nutritional composition of the feeds. Direct infection of birds is normally associated with the respiratory tract, with nervous system and eye problems the sequelae<\/a><\/span> of\u00a0the\u00a0condition.<\/strong><\/p>\nApergillosis is by far the most common mycosis<\/a><\/span> of birds and is an economically important respiratory disease in poultry (Charlton et al<\/em>., 2013<\/a>). Losses are incurred through bird mortality and carcass condemnation.\u00a0Other fungi and yeasts associated conditions include dactylariosis and candidiasis.<\/strong><\/p>\nRespiratory aspergillosis is not commonly found in modern, clean commercial poultry systems. Infection is by the inhalation of spores, normally associated with litter, bedding and feed. Infection can also originate from infected eggs\u00a0hatching\u00a0during incubation and releasing a large number of spores, thus infecting other chicks (Pattison et al<\/em>, 2008<\/a>).\u00a0Infection, particularly in young birds often results in brooder pneumonia (see box below). Although aspergillosis\u00a0is predominantly a disease of the respiratory tract, other organs can be infected (Beernaert et al<\/em>., 2010<\/a>). Systemic infection usually to the brain or eyes, sometimes occurs (Wallace, 1976<\/a>). Clinical signs are often non-specific and dependent on the organ involved (Charlton et al<\/em>., 2013<\/a>).<\/strong><\/p>\n<\/div>\n<\/p>\n![\"chicks\"](\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2015\/09\/chicks-300x178.jpg\")
<\/a>Newly hatched chicks have an immature immune system making them more vulnerable to mycosis infection.<\/strong><\/p><\/div>\n<\/span>The incidence and severity of disease is increased in warm and wet\/humid environments, as well as in dusty conditions and in situations resulting in high levels of ammonia production. Contaminated poultry bedding\u00a0is often the source of infection.<\/p>\n
Newly hatched chicks are most susceptible to aspergillosis, which manifests as brooder pneumonia. Although older birds may be constantly exposed, an acquired immunity means that new infections rarely develop unless individuals receive excessive exposure. Stress resulting in immunosuppression may also be a factor in adult infections.<\/p>\n
In decreasing order of incidence, spores produced by A. fumigatus<\/em>, A. flavus<\/em>, A. niger<\/em>, A. glaucus<\/em> and A. terreus<\/em> are infective to poultry. Aspergillus<\/em> spores are widely distributed in the environment, found in soil, grains and decaying plant matter and mycosis<\/a><\/span> arises from inhalation of these spores from sources such as equipment, air ducts, contaminated feeds and poultry litter. Wet litter may produce large quantities of spores that are released as litter dries out. The optimum temperature for growth of A. fumigas<\/em> is 104\u00b0F, however few environments impede growth, as it is reported to occur at 48\u00b0F and 131\u00b0F at a range of 11-96% relative humidity (Charlton et al<\/em>., 2013<\/a>).<\/p>\nBrooder pneumonia<\/strong><\/p>\nAspergillosis is often deemed synonymous with \u2018Brooder pneumonia\u2019; however, aspergillosis is just one cause of Brooder pneumonia, which can also be bacterial in origin, with chicks inhaling infected dust in the hatcher. Bacterial strains involved include, Escherichia coli, Staphylococci, Enterococci<\/em> and other faecal strains. Pseudomonas<\/em> is one of the most common bacterial causes, and is also often implicated in outbreaks of omphalitis (also known as navel ill, which is characterized by infected yolk sacs and unhealed navels). The difference is marked during post-mortem, with bacterial pneumonia cases presenting red and purple bloodstained tissue, and with aspergillosis recognizable by the presence of white or\u00a0 yellow spots or lesions.<\/strong><\/p>\nDue to increased knowledge around moldy bedding and feeds, and subsequent improved management, aspergillosis is now relatively uncommon and cases of brooder pneumonia are more likely to arise as a result of a bacterial infection. Long transport times, with poor ventilation when chicks are delivered can exacerbate the condition and antibiotic treatments are necessary for bacterial cases in order to reduce losses and the frequency of any subsequent conditions, such as joint ill. (D. Shingleton, Personal Communication).
