Summary Introduction
To review:
The experimental design for the analysis of digestive tract of the newborn chicks, in such a way to eliminate the possibility of salmmonella infection in digestive tract of newborn chicks.
Introduction:
The gut microbial community and integrity of the gastrointestinal tract (GIT) play important roles in absorption of nutrients, immunity development and resistance from the disease. The changes in the microbial community of chicken may leads to the adverse effects on productivity, feed efficiency and health of the chicken. Thus the microbiome research is essential for the improvement of poultry GI microbiome.

Students have asked these similar questions
You’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene.
Describe an experimental technique you would use to find out where this particular eve enhancer is active.
