Resumo

Coccidiosis is a common and economically significant disease affecting broiler chickens. Caused by protozoa of the genus Eimeria, this disease compromises the intestinal epithelial cells of birds, leading to issues such as poor nutrient absorption and, in severe cases, hemorrhagic lesions. This study aims to understand how Eimeria infection alters the microbiome in the birds' intestines, with the goal of contributing to the development of more effective control and prevention strategies by comparing infected birds with an uninfected control group. Forty Cobb chicks, one day old, were used, divided into two groups: 20 birds infected by Eimeria and 20 from the control group. Infection was induced orally with the Livacox T® vaccine containing Eimeria spp., while the control group received only the vaccine vehicle. The chickens were housed in cages with water and feed provided ad libitum, and on the 14th they were humanely euthanized for sample collection according to ethical guidelines. Cecal content was collected for microbiome sequencing. The data obtained will be subjected to statistical analysis to assess significant differences between the groups. The expected results of this study indicate that Eimeria infection causes significant changes in the microbiota balance, facilitating the growth of pathogenic microorganisms and impairing the functions of beneficial microbes. This imbalance, known as dysbiosis, can compromise the integrity of the intestinal mucosa, reducing the intestine’s ability to absorb nutrients, resulting in poor absorption, and worsening feed conversion. These findings are expected to contribute to the understanding of changes in the intestinal microbiome of chickens challenged by Eimeria spp. infection.
