Aspergillus – The genus Aspergillus contains many related fungi that cause aspergillosis. Aspergillus fumigatus is an important member of this genus. This fungus generates endotoxins, which are typically responsible for aspergillosis. Aspergillus species are prevalent in nature. In dry windy conditions, spores often get airborne and move from one region to another. Spores may enter the human body and grow in the respiratory system, lungs, eyes, and ears. Sick Building Syndrome is a disorder induced by ongoing fungus growth in building structures and ventilation systems. More spores are released as the organism grows. This has the potential to cause widespread respiratory infections and suffering associated with aspergillosis.

Aspergillosis may be lethal, particularly in immunocompromised people. This opportunistic infection is widespread in caged and domesticated birds.

Not all fungi are harmful; in fact, some are essential in the battle against a variety of bacterial illnesses. Albert Alexander was infected with Staphylococci and Streptococci bacteria in the corner of his mouth in 1941. The illness spread to the rest of his face, eyes, and lungs over time. Howard Florey and Earnest Chain, two scientists at the time, had recently started refining a chemical generated by the fungus Penicillium notatum that killed germs and was identified by Alexander Fleming. Albert Alexander’s doctor, Charles Fletcher, was aware that Florey and Chain were seeking a human volunteer to test this medicine on, and so in February 1941, Albert Alexander became the first person to be treated with penicillin. Within 24 hours of receiving his first therapy, his fever had fallen, his hunger had returned, and his infection had begun to heal.

Transmission

Conidia (spores) are inhaled from polluted feed, feces, and dirt. The spores are often present in the environment, and healthy, unstressed birds are typically immune to even high spore levels. Young and aged birds, as well as those on antibiotics, are commonly infected, as are those whose immune systems have been reduced by surgery, reproduction, environmental changes, capture, shipment, or aging.

By invading the egg as the embryo is forming, Aspergillus may potentially infect the developing embryo. When infected eggs are candied, they may have a little greenish hue. After infected embryos hatch, well-developed lesions may occur.

Symptoms

Respiratory distress, gasping, accelerated breathing, voice changes, abnormal droppings, emaciation, regurgitation, poor appetite, diarrhea, anorexia, gout, increased thirst, nasal discharge, conjunctivitis, dyspnea, neuromuscular disease, somnolence, and lesions (yellow or gray nodules and/or plaques in the lungs, air sacs, or trachea; less frequently in the peritoneum,

Treatment

Amphotericin, Flucytosine, Fluconazole, and Itraconazole are antifungal medications. Immunostimulants. Certain localized Aspergillomas may need surgery.

Diagnosis

Clinical symptoms and the lack of bacterial infection might be used to make a preliminary diagnosis. A blood test revealing an increase in white blood cell count, slight anemia, and an increase in monocytes supports this diagnosis. Any questionable patient may have X-rays taken. A radiograph may detect aspergilloma-like densities or nodules. Fungus samples may also be collected and cultivated in a specially prepared culture medium. Aspergillus niger is a widespread environmental pollutant.

Aspergillus presence and strain identification using PCR and sequencing tests

Sample

A cloacal swab and throat culture are advised for evaluating individual birds. If the sample is positive and the clinical indications are positive, the bird should be quarantined immediately and vigorous treatment should commence.

Swabs of aviaries, counters, fans, air filters, nest boxes, and other surfaces are particularly successful in detecting the presence of Aspergillus in the environment. Remember that Aspergillus may be found naturally in some situations and is not harmful.

Handling

Prior to delivery, samples should be kept at 4 degrees Celsius (refrigerator). Samples should be sent in a padded envelope or box. Regular mail is OK for sending samples, however, overnight delivery is preferred.
