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

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.

Dynamic response of the intestinal microbiome to induced coccidiosis in chickens.

Unlabelled: is a major cause of coccidiosis in chickens and a key predisposing factor for other economically significant diseases such as necrotic enteritis. However, a detailed understanding of the intestinal microbiome response to infection is still lacking. This study aimed to comprehensively investigate the dynamic changes of the intestinal microbiome for 14 days post-infection (dpi) with .

Nutritional Modulation of Host Defense Peptide Synthesis: A Novel Host-Directed Antimicrobial Therapeutic Strategy?

The escalating threat of antimicrobial resistance underscores the imperative for innovative therapeutic strategies. Host defense peptides (HDPs), integral components of innate immunity, exhibit profound antimicrobial and immunomodulatory properties. Various dietary compounds, such as short-chain fatty acids, vitamins, minerals, sugars, amino acids, phytochemicals, bile acids, probiotics, and prebiotics have been identified to enhance the synthesis of endogenous HDPs without provoking inflammatory response or compromising barrier integrity.

Environmental DNA assays for Laricobius beetles (Coleoptera: Derodontidae), biocontrol agents of the hemlock woolly adelgid in North America.

The hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), is an invasive pest causing significant ecological and economic damage to certain hemlock tree (Tsuga (Endlicher) Carrière, Pinales:Pinaceae) species. In response to this invasive threat, biological control strategies have been implemented, introducing natural predators such as Laricobius nigrinus Fender (Coleoptera: Derodontidae) and, more recently, Laricobius osakensis Montgomery and Shiyake (Coleoptera: Derodontidae), as specialist predators against A. tsugae.
