In line with the substantial increase in broiler industry worldwide, Clostridium perfringens-induced necrotic enteritis (NE) became a continuous challenge leading to high economic losses, especially after banning antimicrobial growth promoters feeds by many countries. The disease is distributed worldwide either clinical or subclinical form, causing reduction body weight gain and feed conversion ratio, impairing European Broiler Index Production Efficiency Factor. There are several predisposing factors development of NE. Clinical signs varied from inapparent case infection (clostridiosis) obvious enteric (morbidity), followed an mortality level (clostridiosis infection). laboratory diagnoses based on history, signs, gross histopathological lesions, pathogenic agent identification, serological testing, molecular identification. Drinking water treatment most common route for administration antibiotics, such as penicillin, bacitracin, lincomycin. Strict hygienic management practices farm, careful selection ingredients ration formulation, use alternative antibiotic additives all important maintaining efficiency help profitability production. current review highlights NE caused C. perfringens explains advances understanding virulence involved pathogenesis special emphasis available alternatives herbal extracts essential oils well vaccines control prevention chickens.

Salmonellosis is a severe problem that threatens the poultry sector worldwide right now. Salmonella gallinarium and pullorum (Fowl typhoid) are most pathogenic serovars in avian species leading to systemic infection resulting economic losses industry. Nontyphoidal serotypes of (Paratyphoid disease) constitute public health hazard for their involvement food poisoning problems addition zoonotic importance. Also, distribution particularly extensive. They resisted environmental conditions made it difficult control spread long time. Therefore, current review aimed through light on with particular references its pathogenesis, importance, immune response Salmonella, antibiotics resistance, possible methods prevention such using promising alternatives including probiotics, prebiotics, symbiotics, organic acids, essential oils, cinnamaldehyde, chitosan, nanoparticles, vaccines.

Plant extract-based green synthesis of nanoparticles is an emerging class nanotechnology that has revolutionized the entire field biological sciences. Green synthesized are used as super-growth promoters and antifungal agents. In this study, selenium (SeNPs) were using Melia azedarach leaves extract main reducing stabilizing agent characterized by UV-visible spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive (EDX), fourier transform infrared spectrometer (FTIR). The SeNPs exogenously applied on Mangifera indica infected with mango malformation disease. at a concentration 30 μg/mL found to be best which enhanced physiological (chlorophyll membrane stability index), biochemical (proline soluble sugar) parameters. antioxidant defense system was also explored, it reported significantly reduced biotic stress enhancing enzymatic non-enzymatic activities. vitro activity 300 inhibited Fusarium mangiferae most. This study considered first biocompatible approach evaluate potential improve health malformation-infected plants effective management strategy inhibit growth F. mangifera.

BMC Microbiology, Год журнала: 2024, Номер 24(1)

Опубликована: Янв. 12, 2024

Abstract Background As antibiotics and chemotherapeutics are no longer as efficient they once were, multidrug resistant (MDR) pathogens cancer presently considered two of the most dangerous threats to human life. In this study, Selenium nanoparticles (SeNPs) biosynthesized by Streptomyces parvulus MAR4, nano-chitosan (NCh), their nanoconjugate (Se/Ch-nanoconjugate) were suggested be efficacious antimicrobial anticancer agents. Results SeNPs MAR4 NCh successfully achieved conjugated. The spherical with a mean diameter 94.2 nm high stability. Yet, Se/Ch-nanoconjugate was semispherical 74.9 much higher SeNPs, NCh, showed significant activity against various microbial strong inhibitory effect on tested metabolic key enzymes [phosphoglucose isomerase (PGI), pyruvate dehydrogenase (PDH), glucose-6-phosphate (G6PDH) nitrate reductase (NR)]; powerful agent. Furthermore, revealed cytotoxicity HepG2 (IC 50 = 13.04 μg/ml) moderate toxicity Caki-1 (HTB-46) tumor cell lines 21.35 but low WI-38 normal line 85.69 μg/ml). Nevertheless, displayed substantial IC values 11.82 7.83 μg/ml, respectively. Consequently, may more easily absorbed both lines. However, it exhibited very 153.3 μg/ml. Therefore, presented activity. Conclusion convincingly recommended used in biomedical applications versatile potent agents ensuring notable levels biosafety, environmental compatibility, efficacy.
