Performance and Microbial Profiles of Broiler Chickens fed Phytogenic Feed Additives or Probiotics during Coccidiosis
… were performed to evaluate the performance and microbial profiles of commercial broilers fed either PFAs or Eimeria challenged broilers fed probiotics. During the probiotics study, 1056 day-old male Ross broiler chicks were assigned to one of 6 treatments, 8 replicates per treatment, with 22 …

Determining the impact of carrion decomposition on soil microbial activity levels and community composition.
… useful for forensic investigators. Advances in microbial profiling techniques have made it possible to compare microbial community profiles obtained from evidence or crime scenes to individuals and vice versa. Profiling microbial communities associated with cadaver decomposition may provide …

Analysis of Salivary Microbiota in Patients with Full-arch Implant Supported Fixed Prostheses
… colonized by a large number of different microbial species that are in a state of equilibrium. Dysbiosis can be caused by either changes in local or systemic conditions and is associated with increased risk of caries, periodontal disease, oral cancer and systemic diseases such as diabetes, …

Benign, potentially malignant & malignant oral lesions; an analysis of oral and gut microbiota
… sequencing, we analysed the microbiota profiles to determine their potential as biomarkers for oral malignancy. We looked at alpha diversity, beta diversity, taxonomy, differential abundance, and functional profiling. Results: Our results showed distinct gut microbial profiles between …

Physical activity for health: the impact of exercise on the human gut microbiota and pro-inflammatory cytokines
… microbiome, this work suggests that favourable microbial profiles are evident in the elite athlete in comparison to healthy controls. It is apparent that short-term increases in physical activity are not sufficient to induce major changes in physically inactive individuals. Furthermore, we …

Long-Term Lab Scale Studies of Simulated Reclaimed Water Distribution: Effects of Disinfectants, Biofiltration, Temperature and Rig Design
… on important aspects of chemistry and microbial regrowth under laboratory-controlled conditions. Turbidity decreased to 0.78 NTU after biofiltration and chlorinated treatments from 10.0-12.6 NTU for conditions with chloramine and no residuals. SRWDSs were susceptible to sediment …

Shotgun metagenomic approach to the influence of industrialization and social behavior on fecal microbiomes
… importance of those changes. First, we present microbial sequence data from canine coprolites, fossilized fecal samples, that preserve some amount of microbial DNA from the individual’s fecal microbiome. We contextualize these results within the scope of existing data in the literature, …

Integrative genomic analyses of bacterially-associated colorectal cancer
… numerous studies have identified changes in the microbial profiles of CRCs compared to adjacent normal mucosa and compared to healthy controls; however, CRC-associated bacteria have not been concurrently quantified across a single cohort; nor have the relationships between CRC-associated …

Análise metagenômica da comunidade bacteriana de vacas com distúrbios reprodutivos.
… the development and analysis of the comparative microbial profiles. Our results show that in healthy cows the bacteria colonizing the genital tract were in totality host associated and non-pathogenic. The majority were anaerobic with a neutral pH optimal for bacterial growth. The data for the …

Microbial Manipulation as a Therapy in Crohn's Disease
… immune activation, and a perturbed gut microbial community. The current standard of care, immune suppression, targets only the host immune system. Despite a range of recent novel therapeutic drug classes, a therapeutic plateau persists. Microbial therapeutics offer an alternative …

Phosphorus Retention and Transformation in Floodplain Forests of the Southeastern United States
… events.;In a third study, I compare changes in microbial community composition in AL and BW FFs. Soil chemical properties reveal that total P (TP) concentrations were significantly higher in AL compared to BW soils, whereas total C (TC) was significantly higher in BW compared to AL FF soils. …

Evaluation of the precision-fed rooster assay for detecting effects of exogenous carbohydrases and adaptation diet on true metabolizable energy and cecal microbial ecology, short-chain fatty acid profile, and enzyme activity
… or at the end of the TMEn assay for analysis of microbial ecology, short-chain fatty acid (SCFA) profiles, and β-glucanase and xylanase activity. β-Glucanase significantly increased (P < 0.05) the TMEn of barley and xylanase numerically increased the TMEn of rye, but there was no significant …
