Abstract: This is a method and a system for designing a personalized therapeutic intervention for an individual. Each individual has a unique composition of microbiome in the gut, one probiotic or dietary regimen may not have same efficacy in different individuals. The disclosure recommends a personalized therapeutic intervention for improving gut health of an individual by designing personalized therapeutics and diet based on functions of microbiome. The personalized therapeutic intervention is recommended based on several steps including generating a set of knowledge bases, identifying a change in the gut health of an individual by monitoring the gut samples and recommending a personalized therapeutic intervention. The personalized therapeutic intervention comprises at least one of a prebiotic, a probiotic and an optimized diet, wherein the optimized diet is estimated based on optimizing a gut food score, where the gut food score is computed based on the change in the gut health of an individual.

Abstract: A system and method for predicting gut health of an individual using non-invasive technique has been provided. The system is making use of two types of pathways i.e. one which are beneficial to gut health and the second which are harmful to gut health. These two types of pathways are annotated in the genomes of gut bacteria. Best combinations of subsets of these pathways capable of distinguishing between gut commensals and pathogens are assigned as pathway biomarkers. The identified pathway biomarkers are then used to develop scheme for prediction of gut health status.

Abstract: A system and method for identification of key driver responsible for bringing changes in a microbial population is provided. The method involves construction of microbial association networks with each microbial taxa as nodes and their associations as edges and subsequent identification of crucial ‘driver’ nodes involved in the studied disease progression. While comparing a particular node between two networks, this method takes individual nodes and their associations into account as well as the identity of their interacting partners. A taxon in the diseased state with an altered set of associations while still being increasingly important for the whole network necessarily holds a key significance in microbial interplay. Using this rationale, this methodology computes a score to quantify this change for each node and calculates its statistical significance.

Abstract: A method and system for annotation and classification of biomedical text having bacterial associations have been provided. The method is microbiome specific method for extraction of information from biomedical text which provides an improvement in accuracy of the reported bacterial associations. The present disclosure uses a unique set of domain features to accurately identify bacterial associations from the biomedical text. The disclosure further provides a method to use the set of domain features to improve a microbiome crowd sourcing setup and create a refined microbial association network. The refined bacterial association network can also be made corresponding to a disease or healthy state, which can be used for an improved understanding of the bacterial community structure and design therapeutic interventions. This refined bacterial association networks for a disease can then be used for clinical, therapeutic and diagnostic applications for treatment of the disease.

Abstract: A system and method for estimation of functional potential of pathways in genomes/meta-genomes is provided. Initially seed modules are identified and a multi-dimensional tag map is created. Further, pathway annotation is done using a novel 6Q annotation step. Hidden Markov Model (HMM) based search augmented with an analysis of gene context is used to refine the modules using a graph theory based approach. The method uses the multidimensional module tag map to build a backend knowledge base and use the same for an iterative literature search to verify the clustered organization of genes within a pathway. Finally, a score is assigned to compute the contribution of each pathway within the genome/meta-genome.

Abstract: The present disclosure addresses the technical problem related to the identification of microbial basis of a disease in microbiome. A system and method for identification of key driver responsible for bringing a change in a microbial population has been disclosed. A subset of common taxa between the ‘control’ and ‘case’ dataset is chosen and corresponding microbial association network is created. The method involves the characterization of the important community level changes between two association networks (‘control’ and ‘case’) that are obtained for a particular disease or condition. A taxon in the diseased state with an altered set of associations (identified by a high network shift score), while still being increasingly important (identified with a positive increase in betweenness) for the whole network, necessarily holds a key significance in the identification of key driver.

Abstract: Method(s) and system(s) for identifying marker features of various subsets of a multi-dimensional data are provided. Each subset includes various data points associated with various features. Each of the data points are defined by feature values corresponding to the associated features. The method includes identifying feature pairs based on a matrix of the data points and the features, and computing correlation distances between features in each of the feature pairs. The method includes generating a non-linear pattern of the plurality of features in a two-dimensional plane. Additionally, the method includes calculating a threshold feature value for the associated features of the data points of a particular subset and representing the threshold feature value as a threshold non-linear pattern in the two-dimensional plane. The method includes determining the marker features based on a relative position of the features with respect to the threshold feature value in the two-dimensional plane.

Abstract: Systems and methods for analyzing community structures within a plurality of environmental samples are described herein. The method includes obtaining taxa data corresponding to taxonomic groups within the plurality of the environmental samples. Based on the taxa data, an abundance value for each of the taxonomic groups with respect to each of the plurality of environmental samples is determined. Further, based on abundance values, an interaction factor for each pair of the taxonomic groups in the plurality of environmental samples is computed. The interaction factor is indicative of a degree of interaction between a pair of taxonomic groups from among the taxonomic groups. Based in part on interaction factors and abundance values, the plurality of the environmental samples is clustered.
