Characteristics of reproductive tract microbiota in health and disease

This study uses next-generation sequencing to analyze reproductive tract microbiota in healthy and diseased laying hens, identifying pathogenic bacteria and their impact on microbial diversity and function.

Effects of Combined Viral and Bacterial Vaccine on Production Performance in Broiler Chickens

This study evaluates a combined viral and bacterial vaccine in broiler chickens, showing improved feed conversion ratio and antibody production against multiple pathogens.

Immunogenicity of different types of adjuvants in bacterial vaccine

This study compares the immunogenicity of four avian infectious coryza vaccines, finding mineral oil adjuvanted vaccines more effective and recommending a booster six months after the first immunization.

16S rRNA gene sequencing for bacterial identification and infectious disease diagnosis

This study compares 16S rRNA gene sequencing with conventional PCR for bacterial identification and disease diagnosis, finding that sequencing is more sensitive and effective in detecting pathogens and distinguishing healthy from diseased samples.

A detailed analysis of 16S rRNA gene sequencing and conventional PCR-based testing for the diagnosis of bacterial pathogens and discovery of novel bacteria

This study compares 16S rRNA gene sequencing and conventional PCR for diagnosing bacterial pathogens in chickens with swollen head syndrome, finding that sequencing is more reliable and can detect novel bacteria.
