Overview
Megabacteriosis, also known as Avian Gastric Yeast Infection, is a condition that affects the digestive system of birds, particularly in species like budgerigars, canaries, and finches. It is caused by a microorganism known as Macrorhabdus ornithogaster, which resembles a large bacterium but is actually a type of yeast.
Causes
The primary cause of Megabacteriosis is infection by Macrorhabdus ornithogaster. This yeast-like organism colonizes the bird's digestive tract, leading to inflammation and impaired nutrient absorption.
