Hach, 2610696, PathoScreen™ Medium Presence/Absence Powder Pillows, 50/pk

Pathoscreen™ medium was developed for quick detection of common pathogens in drinking water, surface water, or recreational water. Pathoscreen™ media is for the detection of fecal, sulfide-producing bacteria like Salmonella, Citrobacter, Proteus, Edwardsiella and Klebsiella (some spp.) using the presence/absence test, Hach Method 8506. Pathoscreen™ can also be used as an alternative method to coliform testing to obtain a Presence/Absence (P/A) test result.
The medium relies on the production of hydrogen sulfide as an indication of the presence of pathogenic bacteria. When using traditional coliform methods in tropical environments, indigenous E. coli may produce positive reactions when no fecal contamination exists. However, E. coli does not interfere with the Pathoscreen™ test, making it a suitable alternative for monitoring drinking water systems in developing tropical countries, remote field locations, and disaster or emergency situations. Pathoscreen™ medium may also be incubated at ambient temperatures between 25 °C and 35 °C if an incubator is not available.
100-mL sample; 50/pk
Pathoscreen™ is used to detect sulfide-producing waterborne pathogens associated with fecal contamination of water sources.
Simple presence-absence method eliminates need for an incubator in tropical and semi-tropical climates.
Pillowed media eliminates the need for refrigeration.
