The detection and use of salmonellae in studying polluted tidal estuaries.

Abstract

of species of the pathogenic variety can be expected. Bruceila, Salmonella, Shigella, Mycobacterium ( tuberculo sis), Vibrio cholera, Entamoeba histo lytica, and various enteric viruses may be present in the feces of warm-blooded animals.

Densities of pathogens in the aque ous environment will be affected by several factors: (a) the type and de gree of treatment given to waste mate rial prior to discharge; (6) the ability of the microorganisms to survive the effects of antibiosis, pr?dation, and chemical constituents in the water; (c) dietary habits and socio-economic status of the community; (d) the prev alence of specific disease in the com munity; (e) endemic conditions in the human and animal population; and
