The mouse-sized naked mole rat (Heterocephalus glaber) is a very unusual mammal. It social animal, living in groups burrows beneath arid African deserts. can live for 30 or more years atmospheres with low oxygen and high carbon dioxide, remarkably resistant to cancer. So the genome sequence, published this issue, might be expected contain some intriguing characteristics. Analysis of its transcriptome reveals genomic features molecular adaptations including strategies improved stability,...
Subterranean mammals spend their lives in dark, unventilated environments that are rich carbon dioxide and ammonia low oxygen. Many of these animals also long-lived exhibit reduced aging-associated diseases, such as neurodegenerative disorders cancer. We sequenced the genome Damaraland mole rat (DMR, Fukomys damarensis) improved assembly naked (NMR, Heterocephalus glaber). Comparative analyses, along with transcriptomes related subterranean rodents, revealed candidate molecular adaptations...
Effective poultry management practices that promote chicken health are crucial for producing higher-quality meat at a lower cost. This study examined the hypothesis increasing space while maintaining stocking density may positively impact health. We evaluated body weight (BW) as an indicator of growth, stress markers, and composition gut microbiome by comparing two housing sizes: smaller (control) larger (treatment) spaces, with 10 birds per 12.3 birds/m2. Chickens in had 15% higher BW (p =...
ABSTRACT Enterococcus faecium NRRL B-2354 is a surrogate microorganism used in place of pathogens for validation thermal processing technologies and systems. We evaluated the safety strain based on its genomic functional characteristics. The genome E. was sequenced found to comprise 2,635,572-bp chromosome 214,319-bp megaplasmid. A total 2,639 coding sequences were identified, including 45 genes unique this strain. Hierarchical clustering with 126 other genomes as well pbp5 locus comparisons...
Abstract The intestinal microbiota affect various physiological traits of host animals such as brain development, obesity, age, and the immune system. In swine industry, understanding relationship between growth stage is essential because directly related to feeding system pigs, thus we studied 32 healthy pigs across five sows at 10, 21, 63, 93, 147 d ages. were altered with separated into three distinct clusters. relative abundance several phyla genera significantly different stages. We...
In the poultry industry, many efforts have been undertaken to further improve growth performance of broilers and identification modulation body weight (BW)-related bacteria could be one strategies productivity. However, studies regarding relationship between microbiota BW are scarce. The objective present study was investigate in different sections gastrointestinal tract (GIT). A total twenty 18-day-old birds were selected based on BW, samples collected from three GIT, which included crop,...
Certain strains of Enterococcus faecium and faecalis contribute beneficially to animal health food production, while others are associated with nosocomial infections. To determine whether there structural functional genomic features that distinct between nonclinical (NC) clinical (CL) those species, we analyzed the genomes 31 E. 38 strains. Hierarchical clustering 7,017 orthologs found in pangenome revealed NC clustered into two clades from CL significantly smaller than genomes, this...
Trace elements are essential to all mammals, but their distribution and utilization across species organs remains unclear. Here, we examined 18 in the brain, heart, kidney, liver of 26 mammalian report elemental composition these organs, patterns species, correlation with body mass longevity. Across observed distinct for abundant elements, transition metals, toxic elements. Some showed lineage-specific patterns, including reduced selenium African mole rats, positive between number...
The gut microbiota in chicken has long been studied, mostly from the perspective of growth performance. However, there are some immunological studies regarding homeostasis chicken. Although CD4+CD25+ T cells reported to act as regulatory (Tregs) chicken, have no showing relationship between and Tregs. Therefore, we established a model for 'antibiotics (ABX)-treated chickens' through administration an antibiotic cocktail consisting ampicillin, gentamycin, neomycin, metronidazole, vancomycin...
Few studies have examined the effects of feeding total mixed ration (TMR) versus roughage and concentrate separately (SF) on ruminant methane production. Therefore, this study compared differences in production, ruminal characteristics, tract digestibility nutrients, rumen microbiome between two methods Holstein steers. A six steers initial bodyweights 540 ± 34 kg were divided into groups assigned to a same experimental diet with different systems (TMR or SF) crossover design 21 d periods....
Abstract The study determined the effects of Lactobacillus salivarius (LS) administered early in life suckling piglets on their growth performance, gut morphology, and microbiota. Thirty litters 3-day-old crossbreed were randomly assigned to one three treatments, treatments commenced day 3 after birth. During whole period experiment, kept with mothers left suckle ad libitum while being supplemented a milk formula or without bacterial probiotic supplemented. control group (CON) was not...
Summary Lactiplantibacillus plantarum (formerly Lactobacillus ) is a lactic acid bacteria species found on plants that essential for many plant food fermentations. In this study, we investigated the intraspecific phenotypic and genetic diversity of 13 L. strains isolated from different foods, including fermented olives tomatoes, cactus fruit, teff injera, wheat boza sourdough starter. We same or similar types frequently exhibited carbohydrate metabolism stress tolerance responses. The...
Bacteria belonging to the genus Pantoea are common colonizers of plant leaf surfaces. Here, we present draft genome sequence agglomerans 299R, a phyllosphere isolate that has become model strain for studying ecology leaf-associated bacterial commensals.
Enterococcus faecalis ATCC 29212, a vancomycin-sensitive strain, has been extensively used as representative control strain for clinical and laboratory experiments. Here we report the draft genome annotation of this containing 3,027,060 bp, with G+C content 37.2% in 126 contigs (≥ 500 bp).
This study examined four lactobacilli isolated from pig feces. Two hundred lactic acid bacteria strains were obtained feces using selective culture media (with vancomycin and bromocresol green; termed LAMVAB agar). Microscopy, the catalase test, Gram-staining, RAPD-PCR analysis used to group into 20 related clusters. Phenotypic API 50 CH test genotypic of 16S rDNA sequences identified these clusters as representing single each Lactobacillus fermentum, salivarius, plantarum, reuteri....
Many Lactobacillus species are frequently isolated from dairy products, animal guts, and the vaginas of healthy women. However, sequencing-based identification strain is time/cost-consuming lobor-intensive. In this study, we developed a multiplex PCR method to distinguish six closely related in acidophilus group (L. gasseri, L. acidophilus, helveticus, jensenii, crispatus, gallinarum), which based on species-specific primer sets. Altogether, 86 genomes 9 National Center Biotechnology...
