Candida albicans testing

Pathogen overview

An opportunistic fungus that overgrows under immunosuppression or antibiotic overuse, causing oral and crop candidiasis.

Transmission

An opportunistic pathogen that overgrows and causes disease when the bird is immunosuppressed, on long-term antibiotics, or kept under poor management such as mouldy feed or unclean drinking water.

Main impact

Causes white pseudomembranes and ulcers in the mouth, throat and crop, interfering with feeding and swallowing and leading to wasting and vomiting; the course is prolonged when secondary infection occurs.

Why testing matters

Confirms Candida infection and differentiates it from oral lesions caused by trichomonads and pigeon pox, guides antifungal treatment, supports withdrawal of inappropriate antibiotics and helps restore gut flora balance.

Common symptoms

• ◆ White plaques and pseudomembranes in the mouth
• ◆ Distended crop with sour-smelling contents
• ◆ Reduced appetite
• ◆ Wasting, vomiting

Differential diagnosis

Must be differentiated from oral lesions such as trichomoniasis and pigeon pox; Candida is characterised by white oral pseudomembranes and a sour-smelling crop and is usually associated with antibiotic overuse.

Incubation period

An opportunistic pathogen that usually causes disease after immunosuppression, long-term medication or malnutrition.

Diagnostic methods

Collect crop and oral swabs for microscopy or culture for confirmation, interpreted together with the whitish pseudomembranous lesions.

Management and treatment

Use antifungal drugs while improving husbandry, supporting immunity and avoiding antibiotic overuse, under veterinary guidance.

Prevention

Use antibiotics judiciously, keep feed and drinking water fresh and support the immunity of the bird.
