The granulosa cells transform from tightly compacted to an expanded mucoid matrix. Various etiologies have been proposed, including trauma, hemorrhage, chronic infection, and mucoid degeneration. Young colonies are described as waxy, mucoid, smooth, and yeastlike. Fluctuating blurring is common, due to tearing and mucoid discharge. Nose examination&colon; The mucosa is usually boggy and edematous with clear mucoid secretions. "N. meningitidis" appears as large colorless to bluish-gray mucoid colonies. It appears as a mucoid lactose fermenter on MacConkey agar. Diarrhea is often watery and non-bloody but may be mucoid and bloody. Eggs are oval and have a mucoid plug at one end. Calves normally suffer from a blood-flecked, thick, mucoid diarrhea. "Pantoea" bacteria are yellow pigmented, ferment lactose, are motile, and form mucoid colonies. The third colony type is smooth, shiny and round with mucoid surrounding it. Mucoid impaction of the upper and lower airways is a common finding. The mucoid substance is toxic to trees and aids in tree decline. Colony morphology on 523M agar is convex, smooth, mucoid with yellow, rose-orange, or pink pigmentation.
