Poultry-associated salmonellosis results in significant costs to poultry producers and consumers. Given the vertically integrated nature of United States industry, a better understanding Salmonella ecology throughout all levels production is essential. One nexus point hatchery, where eggs from multiple broiler breeder farms are incubated hatched, with chicks being sent numerous farms; therefore, hatchery represents an ideal area understand preharvest flow. To achieve this, commercial was biomapped, focusing on prevalence serotype diversity among four major sample type categories (Air, Egg, Water, Facility) across five different places prehatch, hatch, posthatch areas. Following two sets over days, overall 26% (48/184). Of positive samples, highest observed swabs taken floor drains facility transport truck (56%), as well hatch areas (50%). Kentucky (n = 17), Gaminara 12), Alachua 11) were dominant serotypes, serotypes greatest outbreak concern chickens (Enteritidis) representing only 6.25% (3/48) recovered isolates. The area, including underfloor reservoirs trucks, not harbored Enteritidis but also enrichment broths these Salmonella-positive samples possessed sequences matching live-attenuated vaccine Typhimurium strain according CRISPR SeroSeq analyses. These findings highlight complex populations, identifying trucks potentially important critical control points for managers focus their mitigation efforts reduce loads entering live farms.

Biofilms are a critical factor for food safety, causing important economic losses. Among the novel strategies controlling biofilms, essential oils (EOs) can represent an environmentally friendly approach, able to act both on early and mature stages of biofilm formation. This review reports anti-biofilm mechanisms action EOs against five pathogenic bacterial species known their biofilm-forming ability. These include disturbing expression genes related quorum sensing (QS), motility, adhesion, virulence. QS interconnected processes, interfere with communication system (e.g. regulating agrBDCA, luxR, luxS, pqsA genes), thus influencing In addition, is mechanism that regulates gene survival, virulence, pathogenicity. Similarly, also influence many virulence genes. Moreover, exert effects modulating associated adhesion example those involved in curli (csg), fimbriae (fim, lpf), flagella (fla, fli, flh, mot) production, as well ica responsible synthetizing polysaccharide intercellular adhesin. provides comprehensive framework topic better understanding action.

Introduction The emergence of foodborne multidrug-resistant (MDR) Salmonella has attracted considerable global attention. Given that food is the primary transmission route, our study focuses on Bellamya quadrata , a freshwater snail commonly consumed as specialty in Guangxi, China. Methods Eight MDR strains were isolated from samples collected across various markets. Previous animal experiments have confirmed their lethality mice. We determined minimum inhibitory concentrations (MICs) and fractional concentration (FIC) indices cinnamon essential oil (CEO) star anise (SAEO) using microdilution plate checkerboard methods. time-kill curve method was employed to assess antibacterial activity cinnamon-star (SCEO) against planktonic . alkaline phosphatase assay fluorescence microscopy demonstrated SCEO causes damage bacterial cell walls membranes. Crystal violet staining scanning electron (SEM) used observe changes biofilms after treatment. Quantitative real-time PCR utilized analyze expression genes related biofilm formation following Results MIC SAEO be 25 mg/mL, whereas CEO significantly lower at 0.62 mg/mL. FIC index calculated 0.375, which suggests synergistic interaction between two. When combination specific ratios, it enhanced anti-biofilm capabilities compared individual effects or SAEO, potentially through disruption membranes walls. However, treated with SCEO, an upregulation biofilm-associated observed, including csgA, adrA, bcsA csgD This increase may attributed stress-induced transcriptional responses within bacteria. Discussion impacts wall integrity, suggesting its crucial role reducing formation. These findings indicate holds potential alternative traditional antibiotics merits further scientific investigation development.
