title: The effect of sodium sulphacetamide and sodium mandelate in brilliant green agar on the growth of salmonellas.
abstract: An assessment was made of the ability of 425 isolates of salmonellas, belonging to 54 serotypes, to grow on seven selective media. Several isolates of Salmonella dublin and Salm. paratyphi B failed to grow on brilliant green agar supplemented with sodium sulphacetamide and sodium mandelate. On this medium the colonies of 30 isolates which were able to grow were extremely small after 20 h incubation, and consequently their recognition was difficult. The sodium sulphacetamide was responsible for the reduction in colony size.
