Influence of environmental factors and human activity on the presence of Salmonella serovars in a marine environment.

abstract：:A negative enrichment procedure was developed which was capable of isolating Legionella pneumophila directly from seeded air-conditioning cooling tower water onto laboratory media. This procedure was based on an 8-h incubation under conditions that were bactericidal to the indigenous water microflora but merely bacter...
