Predictive device, prediction program and prediction method for predicting causative organism of infection

摘要

Problem to be solved is to provide a more objective discriminant for predicting the causative organism of infection.The problem is solved by a prediction device (10) for predicting the causative organism of the host in the living environment of the host or the host which is the object of the inspection.The prediction unit (10) comprises a processing unit (101).The processing unitObtain array information for each of the plurality of polynucleotides present in the test samples derived from the hostOf the acquired array informationTo heterologous sequence sequence information encoding polynucleotides in heterologous organisms other than the hostLabel labeled species that are inferred from the heterologous biologically derived sequence informationBased on a group of heterologous biologically derived sequence information labeled labelsThe number of lead of the array information corresponding to the label indicating each species is calculated and the diversity index of the species of heterogeneity species detected other than the host is calculatedUsing the logistic regression analysis formulaBased on the calculated lead number and diversity indexFor each label indicating each species, data indicating the possibility of being the cause organism of the infection is producedThe data indicating the possible cause of the infection is suggested to be the cause of infection.A label indicating a species whose number of leads is more than a certain numberAs a label indicating the causative organism of infection,Output prediction result of the infection organism.No selection
