Megabacteriosis (avian gastric yeast)

Overview

Megabacteriosis, also known as avian gastric yeast, is a condition primarily affecting pet birds such as budgerigars, canaries, finches, and parrots. This disease is characterized by an overgrowth of a yeast-like organism called Macrorhabdus ornithogaster that impacts the bird's digestive system.
