Analysis of microbial aerosols diversity in cattle farms in Ningxia.

ABSTRACT:

Introduction

Beef cattle farming, a key industry in Ningxia Hui Autonomous Region, has intensified, raising public health concerns due to bioaerosol emissions. However, the distribution characteristics of these bioaerosols remain poorly understood.

Methods

We characterized bacterial communities in bioaerosols from beef cattle pens across five Ningxia regions-Guyuan (G), Yinchuan (Y), Shizuishan (S), Zhongwei (Z), and Wuzhong (W)-and compared two rearing scales: smallholder farms (S) and large-scale farms (L). Using filter membrane sampling and 16S rRNA gene sequencing, we analyzed bacterial abundance and diversity.

Results and discussion

Regional differences significantly influenced bacterial abundance (p < 0.05), whereas rearing scales had minimal impact. We i
