Background/Objectives: Clostridium perfringens is a normal inhabitant of the intestinal tract poultry, and it has potential to induce cholangiohepatitis necrotic enteritis (NE). The poultry industry suffers significant financial losses because NE, treatment becomes more challenging due resistant C. strains. Methods: antimicrobial antibiofilm activities cellulose nanocrystals/zinc oxide nanocomposite (CNCs/ZnO) were assesses against pan drug-resistant (PDR) isolated from chickens turkeys using phenotypic molecular assays. Results: overall prevalence rate was 44.8% (43.75% in 58.33% turkeys). Interestingly, susceptibility testing isolates revealed alarming PDR (29.9%), extensively (XDR, 54.5%), multidrug-resistant (MDR, 15.6%) isolates, with multiple resistance (MAR) indices ranging 0.84 1. All could synthesize biofilms; among them, 21.7% strong biofilm producers. potentials CNCs/ZnO evaluated by agar well diffusion broth microdilution techniques, results showed activity green inhibition zones’ diameters 20–40 mm MIC value 0.125 µg/mL. Moreover, exhibited great effect pre-existent biofilms dose-dependent manner [MBIC50 up 83.43 ± 1.98 for MBC concentration (0.25 μg/mL)]. transcript levels agrB quorum sensing gene pilA2 type IV pili responsible formation determined quantitative real time-PCR technique, pre- post-treatment nanocomposite. expression both genes downregulated (0.099 0.012–0.454 0.031 0.104 0.006–0.403 0.035, respectively) when compared non-treated isolates. Conclusions: To best our knowledge, this first report nanocomposite’s turkeys.

Development of Antibacterial and Hydrophobic PVDF@ZnO coating on cotton fabrics by electrospinning method.

Results in Surfaces and Interfaces, Год журнала: 2024, Номер 16, С. 100273 - 100273

Опубликована: Авг. 1, 2024

Products with antimicrobial properties enhance personal comfort and hygiene by preventing bacterial infections. In this work, we developed an antibacterial hydrophobic coating combining zinc oxide (ZnO) nanoparticles poly (vinylidene fluoride) (PVDF) through the electrospinning method, aiming for enhanced cotton surface textile applications. Initially, ZnO were synthesized integrated uniformly within PVDF, characterized various analytical techniques. This study highlights coating's remarkable activity, evidenced a significant inhibition zone diameter of 18 mm against Staphylococcus aureus its hydrophobicity, contact angle 136°. Additionally, it was found that Higuchi model could describe diffusion release from PVDF coating. The obtained result allows us to conclude applying method fabric coatings opens new avenues in design functional textiles, particularly ones, as proved paper.
