Abstract: The objective of the current investigation was to evaluate several Eimeria challenges and the resulting alterations in intestinal permeability, intestinal morphology, and intestinal lesion scores in broiler chickens. This study included four groups with ten replicate cages per treatment, in which each group received a different treatment dosage of Eimeria, characterizing high, medium- high, and medium-low challenges. Five days after the challenge, intestinal lesions and permeability were assessed. The results showed that the increase in Eimeria challenge led to a considerable decrease in the height of intestinal villosities, in the ratio between villosity size and crypt depth, and in goblet cells. Moreover, after the challenge, there was a considerable increase in intestinal permeability. In conclusion, the medium-low, medium-high, and high-challenge models can be utilized for experimental infection. In the context of clinical studies, it has been observed that the administration of medium-high and high-challenge doses has proven to be adequate. However, it is advisable to utilize a medium-low challenge level to develop a subclinical challenge model for forthcoming investigations that aim to evaluate nutritional recommendations. |

Bacterial quantification by qPCR is considered the gold standard for microbial molecular diagnosis. However, a fundamental pre-requisite in this methodology is the designing of specific primers for the bacterium of interest. With the increase in bacterial genome sequencing data in the recent years, it has become possible to design specific primers that can be used to quantify different strains of the same bacterial species. Methods: To develop a real-time PCR (qPCR) protocol for the specific quantification of Azospirillum baldaniorum Sp245 strain (old Azospirillum brasilense), the Sp245 genome sequence was fragmented into small contigs with 500 base pairs each, and analyzed for similarity against the NCBI non-redundant database. A. baldaniorum-specific contigs were used to design the primers. The best pair of primers was used to quantify these bacteria after inoculation in different cultivars of Brachiaria, grown under field conditions. Results: Our results showed that the primer pair Sp245p10 was highly specific for the Sp245 strain in the Brachiaria root and shoot field under different conditions. The qPCR assay using these primers showed differences among cultivars in the number of bacteria detected in plants after inoculation. Additionally, the number of bacteria observed in the roots was higher than that in the shoots. Conclusion: The qPCR methodology using a Sp245 strain-specific primer may be used to monitor A. baldaniorum inoculated into other plants and may find potential application in field experiments.
