Highly sensitive detection of Salmonella typhi using surface aminated polycarbonate membrane enhanced-ELISA.

The identification of pathogenic bacteria in water is important for addressing preventive and treatment issues regarding health and safety. A highly sensitive and specific solid-phase sandwich ELISA procedure was developed for the detection of typhoid causing extremely lethal water borne pathogen Salmonella typhi (S. typhi) on modified isopore polycarbonate (PC) black membranes.
