  • EARLY WARNING GENETIC TESTING OF TOXIC CYANOBACTERIA IN WATER SUPPLY
    Publication number: 20240191311
    Abstract: This invention is at least one panel of qPCR/RT-qPCR assays which enables simultaneous testing for the presence of multiple species and subgroups of cyanobacteria that produce microcystin, anatoxin, saxitoxin, and cylindrospermopsin cyanotoxins. The method takes into account that some cyanobacteria species may carry genes associated with multiple toxin types. Testing for each toxin type is conducted under standardized test conditions which allow quantification of the number of gene copies present for cyanotoxins which may contribute to the overall toxin level.

  • SYSTEM FOR EARLY WARNINGS OF CYANOTOXIN PRODUCTION IN SOURCE WATER
    Publication number: 20240084371
    Abstract: A computer system for generating early public warnings and predictions of cyanotoxin production in source water comprised of the a processor for instantiating RT-qPCR test data objects for storing RT-qPCR gene expression data wherein each RT-qPCR test data object is identified by test location, test year. Each RT-qPCR test data object includes one or more multi-dimensional array objects. Each multi-dimensional array object is configured to store ordered sets of data wherein each of said ordered pairs is comprised of measurement dates and a detection value.

  • Species-specific primer sets and identification of species-specific DNA sequences using genome fragment enrichment
    Patent number: 8574839
    Abstract: Targeted sequencing of genetic regions that differ between two DNA preparations uses genomic fragment enrichment. This method can be used to study genetic variation among closely related species and microbial communities, particularly for identifying sources of fecal pollution.
