Метагеномическая профайлирование Фекальной и Цекальной микробиоты и их антимикробных генов сопротивления на заднем дворе птицы коренных народов.

Преобладающим видом птицы в развивающихся странах является птица на заднем дворе коренных народов. Сельские мелкие фермеры в этих районах, как правило, используют систему свободного распределения (задние дворы), которая подвергает птицу различным условиям и широкому спектру микроорганизмов, влияющих на их рацион питания и кишечную микробиоту. В этом поперечном исследовании мы провели оценку микробных профилей местных птиц из заднего двора и их антимикробных генов устойчивости (ARGs) с использованием как цекаловых образцов, которые обеспечивают более точное представление кишечника кишечника мик
