Cryptosporidium & Giardia Viability Testing Services
In addition to the detection of Cryptosporidium and Giardia in submitted samples, we also provide potenial viability testing by vital dye staining. This procedure lacks the sensitivity and accuracy to determine the viability of the detected cysts and oocysts. Thus to reliably and accurately asses viability of Cryptosporidium oocysts, we perform a cell culture infectivity assay. We utilize the foci detection method on infected HCT-8 Cell monolayers. At the clients request, submitted samples are analyzed for infectious C. parvum as per the method described by Slifko et al. (1999), Johnson et al. (2006), and recommendations from American Water Works Association Research Foundation (AWWARF 3021; Detection of Infectious Cryptosporidium in Filtered Drinking Water).
