Abstract

Background: are the principal causative factor in the etiological factors of chronic, active, or type B gastritis; peptic and duodenal ulcers; stomach carcinoma; and epithelial tissue lymphoid malignancies. It infects more than half of the population worldwide. To reduce production, pharmacological therapy of diseases typically involves using threefold treatment methods. However, as a result of such therapy, antimicrobial resistance is commonly developed. Alternative therapeutics for diseases are thus of particular interest.

Methods: Thyme essential oils (EOs) obtained from Jalas plants in Iran were tested for antibacterial activity against obtained from 320 poultry specimens in this investigation. Antibacterial activity was measured using inhibition zones, minimum inhibitory concentrations (MICs), and minimum bactericidal concentrations (MBCs). The impact of Jalas essential oils on isolate , , and gene expression was evaluated using a quantitative real-time PCR method ( < 0.05).

Results: The chemical content of these EOs varied significantly according to chromatographic examination. Thymol, carvacrol, and terpinene-4-ol are the most abundant components in these EOs. was recognized as a species with a 175-bp PCR product of 16S rRNA in 20/20 (100%). According to PCR results, all 20 (100%) isolates belonged to . The EOs inhibited in a dose-dependent manner, with Jalas being the most effective, followed by pterygium EOs in decreasing order. At 8 mg/mL of Jalas EOs, IZs against were 27.4 ± 0.42 mm, and at 8 mg/mL of pterygium, IZs against were 1 ± 0.02. Jalas essential oils were used to treat all bacteria, and the findings showed that Jalas had a substantial inhibitory impact on the expression of , , and virulence-related genes ( < 0.05).

Conclusions: In a dose-dependent manner, the EOs of Jalas EO demonstrated a high degree of antimicrobial property against bacteria. The most efficient EOs were those from Jalas with relative concentrations of thymol and carvacrol, followed by the coumarin-dominated pterygium EO with reduced antibacterial activity.
