Background: Autism Spectrum Disorder (ASD) is increasingly associated with alterations in gut microbiota, intestinal permeability, and immune dysregulation. However, integrative studies exploring these mechanisms in Latin American populations are lacking. Objective: To characterize gut microbiota profiles in Colombian children with ASD and evaluate the effects of two microbiota-targeted interventions, an anti-inflammatory diet and a probiotic formulation, on microbial diversity and taxonomic composition. Methods: In a two-phase study, shotgun metagenomic sequencing was performed on fecal samples from 23 children with ASD and 7 typically developing (TD) controls. In the second phase, 17 children with ASD were randomized to receive a 12-week …

Apolipoprotein E4 allele (APOE4) carriers show early metabolic changes, heightening the genetic risk of late-onset Alzheimer's Disease (AD), characterized by amyloid-β and tau tangle plaques and neurodegeneration. Its development is influenced by age, environment, and genetics, with Mild Cognitive Impairment (MCI) often preceding AD, providing a crucial window for early intervention. Factors in AD progression include sex differences and gut microbiome imbalances, with women disproportionately affected and APOE4 carriers showing early metabolic and cognitive changes. This study explores the potential of prebiotic inulin, probiotic Bifidobacterium animalis, and fecal microbiota transplants (FMT) from healthy donors to mitigate AD …

Necrotizing enterocolitis (NEC) is a leading cause of premature newborn morbidity and mortality. The clinical features of NEC consistently include prematurity, gut dysbiosis and enteral inflammation, yet the pathogenesis remains obscure. Herein we combine metagenomics and targeted metabolomics, with functional in vivo and in vitro assessment, to define a novel molecular mechanism of NEC. One thousand six hundred and forty seven publicly available metagenomics datasets were analyzed (NEC = 245; healthy = 1,402) using artificial intelligence methodologies. Targeted metabolomic profiling was used to quantify the concentration of specified fecal metabolites at NEC onset (n = 8), during recovery ( …

Rotifers are used as the first feed for marine fish larvae and are grown in large cultures that have high loads of organic matter and heterotrophic bacteria; these bacteria are passed on to the developing fish larvae and can potentially lead to bacterial infections. A modified minimum inhibitory concentration (MIC) protocol for antimicrobial peptides was used to determine the potency of ten antimicrobial peptides (AMPs) in artificial seawater relevant to a rotifer culture (salinity of 25‰) against common marine pathogens. All of the AMPs had antimicrobial activity against the bacterial isolates when the salt concentration was approximately zero. However, in …
Recent Advances In Probiotic Application In Animal Health And Nutrition: A Review, Sarayu Bhogoju, Samuel Nahashon

Biotechnological advances in animal health and nutrition continue to play a significant role in the improvement of animal health, growth, and production performance. These biotechnological advancements, especially the use of direct-fed microbials, also termed probiotics, those genetically modified and otherwise, have minimized many challenges facing livestock production around the world. Such advancements result in healthy animals and animal products, such as meat, for a growing population worldwide. Increasing demand for productivity, healthy animals, and consumer food safety concerns, especially those emanating from excessive use of antibiotics or growth promoters, are a driving force for investing in safer alternatives, such as …

Master's Theses
The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has increased over the past decades, creating a need for animal models that recapitulate the features of the pediatric disease. Iberian pigs have a leptin-resistant phenotype characterized by hyperleptinemia, hyperphagia, and extreme adipogenesis. We hypothesized that neonatal Iberian pigs fed a high fat high-fructose (HFF) diet will develop a pattern of liver injury resembling pediatric NAFLD. In addition, we sought to determine if a mixture of probiotics would prevent the disease. Animals were fed 1 of 4 diets containing (g/kg body weight × d) 0 g fructose, 11 g fat …

Health care providers (N = 256) completed an online questionnaire to assess their knowledge, perceptions, and use of probiotics and prebiotics. Participants were familiar with probiotics (88%) but not with prebiotics (22%). Probiotics (62%) and prebiotics (55%) were perceived as being “somewhat” to “quite a bit” beneficial to health (μ = 3.6 ± 1.0 and 3.6 ± 1.2, respectively). Health care providers were “quite a bit” to “very much” willing to recommend probiotics (77%) and prebiotics (83%) if substantiated with literature. Despite this belief, they did not recommend probiotics (45%) or prebiotics (26%) to patients or read current research …
