Accurate prediction of Escherichia coli contamination in surface waters is challenging due to considerable uncertainty in the physical, chemical and biological variables that control E. coli occurrence and sources in surface waters. This study proposes a novel approach by integrating hydro-climatic variables as well as animal density and grazing pattern in the feature selection modeling phase to increase E. coli prediction accuracy for two cascading dams at the US Meat Animal Research Center (USMARC), Nebraska. Predictive models were developed using regression techniques and an artificial neural network (ANN). Two adaptive neuro-fuzzy inference system (ANFIS) structures including subtractive clustering and fuzzy c-means (FCM) clustering were also used to develop models for predicting E. coli. The performances of the predictive models were evaluated and compared using root mean squared log error (RMSLE). Cross-validation and model performance results indicated that although the majority of models predicted E. coli accurately, ANFIS models resulted in fewer errors compared to the other models. The ANFIS models have the potential to be used to predict E. coli concentration for intervention plans and monitoring programs for cascading dams, and to implement effective best management practices for grazing and irrigation during the growing season.

The purpose of this study is to collect information from study participants who are hospitalized with an invasive disease caused by Extraintestinal pathogenic E. coli (ExPEC). This informa...
The sequence type 131 (ST131) is a predominant lineage among extraintestinal pathogenic Escherichia coli. It plays a major role in the worldwide dissemination of E. coli that produce exten...
This study is to evaluate lot-lot consistency of Recombinant Hepatitis E Vaccine (Escherichia Coli) Hecolin®.
Strains of ESCHERICHIA COLI that are a subgroup of SHIGA-TOXIGENIC ESCHERICHIA COLI. They cause non-bloody and bloody DIARRHEA; HEMOLYTIC UREMIC SYNDROME; and hemorrhagic COLITIS. An important member of this subgroup is ESCHERICHIA COLI O157-H7.
Strains of Escherichia coli that possess virulence traits which allow them to invade, colonize, and induce disease in tissues outside of the GASTROINTESTINAL TRACT. They are a cause of URINARY TRACT INFECTIONS (UROPATHOGENIC ESCHERICHIA COLI); neonatal MENINGITIS; SEPSIS; PNEUMONIA; and SURGICAL WOUND INFECTION.
An enterohemorrhagic Escherichia coli of the O subfamily that can cause severe FOODBORNE DISEASE. The H4 serotype strain produces SHIGA TOXINS and has been linked to human disease outbreaks, including some cases of HEMOLYTIC-UREMIC SYNDROME, resulting from contamination of foods by feces containing E. coli O104.
A species of gram-negative, rod-shaped bacteria belonging to the K serogroup of ESCHERICHIA COLI. It lives as a harmless inhabitant of the human LARGE INTESTINE and is widely used in medical and GENETIC RESEARCH.
A verocytotoxin-producing serogroup belonging to the O subfamily of Escherichia coli which has been shown to cause severe food-borne disease. A strain from this serogroup, serotype H7, which produces SHIGA TOXINS, has been linked to human disease outbreaks resulting from contamination of foods by E. coli O157 from bovine origin.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
