title: Neuraminidase activity in Mycoplasma gallisepticum.
abstract: The whole viable Mycoplasma gallisepticum (strain TT) organisms were found to possess neuraminidase activity with a pH optimum of 5.8 on substrates such as human transferrin, human alpha(1)-glycoprotein, and rabbit serum. The enzyme operated optimally at pH 4.5 when N-acetylneuraminyl-lactose was used as the test substrate.
