Is Intestinal Microbiota Fully Restored After Chickens Have Recovered from Coccidiosis?
Pathogens

Department of Animal and Food Sciences, Oklahoma State University, Stillwater, OK 74078, USA.
The intestinal microbiota is known to be altered by -induced coccidiosis, but it remains unclear whether the microbiota is fully restored after recovery. To address this, 110 newly hatched Cobb male broiler chickens were challenged with 2 × 10 sporulated oocysts of (EM) strain M6 or mock-infected with saline on day 10. Body weight and feed intake were recorded.

Spore-forming bacterial species pose a serious threat to food plants and healthcare facilities that use high-temperature processing and sterilizing techniques to sanitize medical equipment and food items. These severe processing conditions trigger sporulation, which is the process by which spore-forming bacteria, such as those of the and species, begin to produce spores, which are extremely resilient entities capable of withstanding adverse environmental circumstances. Additionally, these spores are resistant to a wide range of disinfectants and antibacterial therapies, such as hydrolytic enzymes, radiation, chemicals, and antibiotics.

Impaired intestinal integrity in broilers reduces performance and health, highlighting the importance of accurately measuring intestinal permeability (IP) to maintain gut health. The objective of this study was to evaluate the efficiency of iohexol as an IP marker in broilers challenged with , , or both during both peak challenge (day [d] 21) and recovery (d 28) periods. One-day-old male Ross 708 birds (n = 56) were distributed into 4 treatment groups: NC (no-challenge control); EM (challenged with 5,000 .

Clostridioides difficile is a spore-forming pathogen capable of causing severe disease in humans. Critical stages in the biological cycle of this microorganism include sporogenesis/germination and toxin production by vegetative cells. Antagonizing these pivotal events could aid in prevention and treatment to manage this pathogen.

Bacterial noncoding RNAs fulfill a variety of cellular functions as catalysts, as scaffolds in protein complexes or as regulators of gene expression. They often exhibit complex tertiary structures that are a key determinant of their biochemical function. Here, we characterize the structured "raiA motif" RNA from Clostridioides difficile, which is conserved in more than 2,500 bacterial species from the phyla Bacillota and Actinomycetota.
