This study aimed to investigate the effect of dietary cysteamine hydrochloride (CSH) on the growth performance, oxidation, inflammation, and gene expression of cytoskeleton and tight junction in the intestinal mucosa of broiler chickens challenged with Clostridium perfringens (C. perfringens). A total of 360 one-day-old broiler chicks were randomly distributed into 5 groups for a negative control (NC, without C. perfringens challenge), a positive control (PC, with C. perfringens challenge), and PC plus CSH at 100, 150, or 200 mg/kg of diet. The results showed that average daily gain, gain:feed, cecal population and enterotoxin of C. perfringens were negatively affected (P < 0.05) by the C. perfringens challenge, but were conversely affected (P < 0.05) by the CSH supplementation, and G:F reached to the level of NC group. The PC group increased (P < 0.05) serum diamine oxidase, malondialdehyde, protein carbonyl, interleukin-6, interleukin-1β, and tumor necrosis factor-α, whereas the supplementation of CSH decreased (P < 0.05) these parameters. Moreover, the C. perfringens challenge worsened the disruption of intestinal mucosal cytoskeleton and tight junction by downregulating (P < 0.05) the mRNA levels of actin protein of muscle Z-line alpha, syncoilin, synemin, tubulin, claudin-1, and zona occludens protein-2, while these parameters were partially compensated (P < 0.05) by CSH supplementation. For the dose trends of CSH, there were linear and quadratic (P < 0.05) effects on gain:feed, enterotoxins, tumor necrosis factor-α, tubulin alpha 1c, syncoilin, and synemin. In conclusion, the CSH can be an alternative against C. perfringens infection by beneficially regulating gut pathogenic bacteria and enterotoxins, oxidation, inflammation, cytoskeleton, and tight junction in broiler chickens.

Necrotizing fasciitis is a potentially life-threatening infection that can lead to rapid muscular and fascial necrosis, often resulting in sepsis. In addition to the rapid disease progression, diagnosing this disease in children can be challenging as they cannot accurately communicate their symptoms. Spontaneous necrotizing fasciitis secondary to Clostridial infection has rarely been described in the literature but occurs in neutropenic patients with significant morbidity and mortality from myonecrosis and gas gangrene.

This experiment aimed to compare the efficacy of an antimicrobial peptide (AMP) with a conventional antibiotic growth promoter (AGP) during necrotic enteritis (NE) challenge in broilers. In total, 720 1-day-old exclusively male broiler chicks (Ross-308) were allocated to five treatments, each with six replicates of 24 birds (n = 144/treatment), for 35 days. The treatments were as follows: (1) uninfected control (UC) with basal diet, (2) infected control (IC) with C.

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 .

Bacterial infections causing necrotic enteritis and diarrhea pose a considerable economic loss to the animal industry. Using mannose oligosaccharides as competitive exclusion agents is an alternative method to antibiotic growth promoters; however, these materials are rapidly metabolized by gut microbiota, posing a challenge in sustaining their efficacy. The aim of this study was to identify an agglutination material that is effective against pathogens.

It is urgent to develop effective antibiotic alternatives for the control of subclinical necrotic enteritis (NE) in chickens after in-feed antibiotics have been banned. The current study investigated the efficacy of drinking water supplemented with essential oils and organic acids mixtures (EOA) on growth performance and intestinal health of broilers challenged with necrotic enteritis (NE). A total of 360 one-day-old Arbor Acres male broilers were randomly divided into 5 treatment groups, including non-challenged control group (T0), challenged NE group (T1), and challenged NE chickens treated with 0.
