Comparative analysis of gut fungal composition and structure of the yaks under different feeding models
Researchers compared the gut fungal communities of wild yaks, house-fed domestic yaks, and grazing domestic yaks on the Tibetan plateau. They found that wild and grazing yaks had significantly more diverse gut fungal communities than house-fed yaks, with the feeding model strongly influencing which fungal species thrived. The study suggests that natural grazing supports a richer gut microbiome in yaks compared to indoor feeding, with potential implications for animal health and digestion.
Aberrant microbiomes are associated with increased antibiotic resistance gene load in hybrid mice
Researchers studied gut microbiome composition and antibiotic resistance gene content in hybrid mice compared to their parent species using amplicon sequencing. They found that hybridization between genetically divergent mouse populations was associated with aberrant microbial communities that carried a higher load of antibiotic resistance genes. The study suggests that host genetics may play a previously underappreciated role in shaping both gut microbiome composition and the spread of antimicrobial resistance.
