Bordet-Gengou agar medium supplemented with albumin-containing biologics for cultivation of bordetellae.

Bordetella pertussis, B. parapertussis, and B. bronchiseptica cause respiratory infections in mammals, including humans, and are generally cultivated on Bordet-Gengou (BG) agar plates in laboratories. The medium requires animal blood as a supplement for better bacterial growth. However, using blood is problematic, as its constant supply is occasionally difficult because of the limited shelf-life. This study proposes modified BG agar plates supplemented with bovine serum albumin and fetal bovine serum as a simple and convenient medium that confers sufficient growth of bordetellae.
