“…NE can increase MDA concentrations in the body [20,21] and decrease the activities of antioxidant enzymes such as catalase [22]. In the present study, we observed that NE reduced the antioxidant capacity of the body by decreasing T-AOC and increasing MDA concentrations; these results are consistent with those of previous studies [23,24]. Oxidative damage is caused by an imbalance between antioxidant defense and free radical generation systems [25].…”

Clostridium perfringens causes necrotic enteritis (NE) after proliferation in the intestine of poultry, resulting in considerable losses to the poultry industry. This study aimed to investigate the impact of tannic acid on the antioxidant, immunity, and gut health of broilers with NE. In the experiment, 630 one-day-old Cobb500 male chicks were randomly divided into six treatment groups, with seven replicate cages and with fifteen birds in each cage. The treatment groups were as follows: control group (NC), challenged group (PC), and challenged NE chickens treated with 250, 500, 750, and 1000 mg/kg tannic acid (PTA1, PTA2, PTA3, and PTA4, respectively). To induce NE, coccidia vaccine and Clostridium perfringens were administered on day 19 and days 22–28, respectively. Indexes related to antioxidant, immune, and intestinal health were measured on days 28 and 35. During the infection period, we observed significant increases in fecal water content, D-LA, TNF-α, and malondialdehyde concentrations (p < 0.05). Conversely, significant decreases were noted in chyme pH and in T-AOC, IL-4, and IL-10 concentrations (p < 0.05). The addition of tannic acid exhibited a linear decrease in fecal water content and TNF-α concentration (p < 0.05). Furthermore, tannic acid supplementation resulted in a quadratic curve decrease in D-LA concentration and linear increases in T-AOC, IL-4, and IL-10 (p < 0.05). Cecal microbiological analysis revealed that Ruminococcaceae and Butyricimona were dominant in PTA3. In conclusion, the dietary addition of tannic acid may reduce the negative effects of NE by increasing antioxidant and anti-inflammatory capacity, improving the intestinal barrier, and regulating the intestinal flora.

“…Hemoglobin binding protein-encoding gene ( hgbA ), neuraminidase gene ( nanH ), iron acquisition protein ( exhB ), and superoxide dismutase ( sodA, sodC ) were detected with 66.6, 50, 70, 100, and 93% prevalence, respectively. Differences in virulence profiles between investigations revealed that various P. multocida isolates may have diverse pathogenic mechanisms (Li et al 2018 ; Abd El-Hamid et al 2019 ; El-Demerdash et al 2023b ).…”

The present study aimed to isolate Pasteurella multocida (P. multocida) from pulmonary cases in several avian species and then investigate the histopathological features, antimicrobial resistance determinants, virulence characteristics, and risk factors analysis of the isolates in each species in correlation with epidemiological mapping of pasteurellosis in Sharkia Governorate, Egypt. The obtained data revealed a total occurrence of 9.4% (30/317) of P. multocida among the examined birds (chickens, ducks, quails, and turkeys). The incidence rate was influenced by avian species, climate, breed, age, clinical signs, and sample type. Antimicrobial susceptibility testing revealed that all isolates were sensitive to florfenicol and enrofloxacin, while 86.6 and 73.3% of the isolates displayed resistance to amoxicillin-clavulanic acid and erythromycin, respectively. All of the P. multocida isolates showed a multiple-drug resistant pattern with an average index of 0.43. Molecular characterization revealed that the oma87, sodA, and ptfA virulence genes were detected in the all examined P. multocida isolates. The ermX (erythromycin), blaROB-1 (β-lactam), and mcr-1(colistin) resistance genes were present in 60, 46.6, and 40% of the isolates, respectively. Ducks and quails were the most virulent and harbored species of antimicrobial-resistant genes. These results were in parallel with postmortem and histopathological examinations which detected more severe interstitial pneumonia lesions in the trachea and lung, congestion, and cellular infiltration especially in ducks. Epidemiological mapping revealed that the Fakous district was the most susceptible to pasteurellosis infection. Thus, farmers are recommended to monitor their flocks for signs of respiratory disease, seek veterinary care promptly if any birds are sick, and avoid the random usage of antibiotics. In conclusion, this study presents a comprehensive picture of the risk factors in correlation to the pathognomonic characteristics of P. multocida infection in poultry sectors to help in developing more effective strategies for prevention and control.

“…This is because it has a high moisture content, minerals, nitrogenous substances, and a trace amount of fermentable carbohydrates, such as glycogen. In addition, meat’s pH encourages the majority of bacteria to grow and reproduce ( Alahakoon et al ., 2015 ; El-Demerdash et al ., 2023b ). Raw meat and minced meat can contain Escherichia coli ( E. coli ), Listeria monocytogenes ( L. monocytogenes ), and Staphylococcus aureus ( S. aureus ), which pose significant health risks to individuals who consume contaminated food.…”

Background: Minced meat is a valuable source of nutrients, but it is vulnerable to contamination by microorganisms commonly present in the environment. Additionally, there is a risk of adulteration with cheaper meat sources, which can be harmful to consumers. Aim: It is crucial to identify meat adulteration with distinct microbiological analysis for legal, economic, religious, and public health purposes. Methods: A total of 100 minced meat samples were collected from several markets in Sharkia Governorate, Egypt. These samples were then subjected to bacteriological testing and an advanced multiplex PCR method. This method enables the detection of bovine, equine, porcine, and dog species in meat samples with just one step. Results: The adulterated samples had a higher total bacterial count and pH values compared to pure bovine meat. These differences in bacterial count and pH values were statistically significant, with p-values of 0.843 (log10) and 0.233, respectively. The frequency of E. coli occurrence was 13%, and the O111 serotype was predominant in the adulterated samples. Listeria monocytogenes and S. aureus were isolated with prevalence rates of 3% and 29%, respectively. Besides, the SYBR-green multiplex real-time PCR assay used in this study detected adulteration with dog, equine, and porcine meats in the examined samples at rates of 9%, 5%, and 4%, respectively. Conclusion: This method provides a sensitive and specific approach to detect issues related to well-being and safety.
