Contributing factors to child stunting in Guatemala: A systems analysis focused on enteric disease transmission and mycotoxin exposure
… among children in Guatemala 1) environmental enteric dysfunction (EED) is correlated with height-for-age, 2) aflatoxin B (AFB) exposure is correlated with height-for-age, and 3) AFB exposure is correlated with EED. A network analysis was conducted on data from the US Agency for International …

The Effects of Water Storage and Meteorological Conditions on Enteric Infections from a Matched-Control Trial in Beira, Mozambique
… has the potential to reduce the burden of enteric diseases, including diarrhea, in rapidly growing urban centers. However, water intermittency and water storage practices, as well as impacts of meteorological conditions, may interfere with the progress made by drinking water interventions. …

Managing Poultry Gut Integrity, Immunity and Microbial Balance During Necrotic Enteritis
Necrotic enteritis (NE) is a major enteric disease in commercial poultry and manifests itself in clinical and subclinical forms. Despite years of research, NE is still among the leading diseases with the greatest economic impact on poultry production. Subclinical forms lead to poor performance …

The effects of yeast derivatives and adult cecal droppings on growth parameters and intestinal morphology in commercial broilers
… bacteria is important for rapid growth and enteric disease resistance of the modern broiler. Three studies measured the impact of yeast derivatives in diets of broilers. The objective of the first study was to determine if yeast products alone or in combination effected performance or gut …

The ultrastructural morphology of Eimeria tenella exhibits striking natural variation and undergoes significant changes during the first few hours of infection
… protozoan organisms capable of causing enteric disease in a vast array of animals. Working with Eimeria tenella, a clinically and economically significant pathogen of chickens, I have quantified the fusion dynamics of the refractile bodies. Refractile bodies are non-membrane-bound …

The association of Clostridium perfringens with foal diarrhoea
… perjringens</i> involvement in equine enteric disease have not identified the prevalence and statistical association of these bacteria with foal diarrhoea. Each of five methods which favoured the recovery of <i>C. perjringens</i> in different physiological states were chosen to improve …

Development of a Turkey Coccidiosis Vaccine Candidate: an Attenuated Line of the Protozoan Parasite, Eimeria meleagrimitis
<p>Coccidiosis is an economically important enteric disease of poultry caused by protozoan parasites belonging to the genus Eimeria. Drugs are most commonly used to control coccidiosis. Widespread usage of anticoccidial drugs in the field has resulted in development of drug resistant strains and …

Multi-omics investigation of interactions between persistent bacteria and Salmonella in the inflamed gut
Salmonella is a globally relevant enteric pathogen responsible for numerous outbreaks and debilitating illness yearly. Expansive tropism allows Salmonella to find bastion in zoonotic reservoirs including prominent food animals. Continued prophylactic antibiotic use in livestock and therapeutic …

Characterization of Host Immune Responses to Eimeria adenoeides Infection in Turkey Poults
<p>Coccidiosis is a common enteric disease of turkeys that is caused by protozoan parasites belonging to the genus <em>Eimeria</em>. There are about seven species of <em>Eimeria</em> that affect turkeys and of these <em>E. adenoeides</em> is the most pathogenic and commonly recognized. Infection …

Influence of Incubation Conditions on Turkey Poult Intestinal Development and Susceptibility to Poult Enteritis
… performance and may predispose poults to enteric disease. The objective of the first study was to provide a baseline of responses to incubation conditions so that further studies could be conducted on whether these stressors may increase susceptibility to post-hatch infection. Commercial …

Investigating Private Drinking Water Quality and Biomarkers of Associated Health Outcomes in Southwest Virginia
… drinking water and associated biomarkers of disease. This relative lack of data is particularly acute in Central Appalachia, a region defined by high poverty, aging public infrastructure, and high rates of private water supply. This study aims to measure the prevalence of health outcomes …

Characterization of virus strain- and pig age-dependence of porcine epidemic diarrhea virus: Implications for vaccine development
… causative agent of porcine epidemic diarrhea, an enteric disease affecting pigs of all ages that impacts the global swine industry. Although PEDV was first identified in Europe in 1970s and spread to some Asian countries thereafter, PEDV did not emerge in the United States until 2013. Since then, …

Innate immune evasion and interferon antagonism by porcine epidemic diarrhea virus
… diarrhea (PED) is a highly contagious and acute enteric disease of swine featured by vomiting, watery diarrhea, and severe dehydration causing high mortality in piglets. In the U.S., PED emerged for the first time in 2013 and severely affected most pig-producing states. The causative agent is PED …

Modelling the interactions of Salmonellae with the human host using stem cell-derived intestinal organoids and macrophages
… bacteria, and are an important cause of enteric disease in humans and in animal hosts worldwide. Their transmission is predominantly via the faeco-oral route and members of the Salmonella enterica species can be arbitrarily classified into typhoidal and non-typhoidal types based on their …

The use of infrared thermography and behavioural and physiological responses as early disease indicators in calves
Disease is widely acknowledged to be detrimental to an animal’s welfare and generates significant economic losses. To minimise the impact of disease on animal welfare and consequently reduce economic costs, early disease detection is essential for promoting earlier diagnosis, treatment and …
