Which of the following symptoms is NOT characteristic of frounce?

Frounce, also known as trichomoniasis, is a disease caused by a parasitic infection that primarily affects birds, particularly raptors. The symptoms associated with frounce can include cheesy plaques in the mouth, which are a hallmark sign of the infection. These plaques are the result of the parasite attacking the mucous membranes of the oral cavity.

Flicking food is another behavior that can be observed in affected birds, as they struggle to eat due to oral lesions and discomfort. Weight loss is common as well because the bird's ability to consume food is impaired by the mouth lesions and associated discomfort, leading to inadequate nutrition.

Labored breathing, however, is not a typical symptom of frounce. While it may arise due to other respiratory illnesses or complications, it is not characteristic of the disease itself, which primarily manifests through oral symptoms and their consequences. Understanding these distinctions helps in recognizing specific avian diseases and ensuring proper diagnosis and treatment.
