Salmonella is an essential food-borne pathogenic microorganism. Humans could get infected by consuming of Salmonella-contaminated foods, especially contaminated meat. In this study, a total of 580 retail meat samples (280 pork, 240 chicken, and 60 goose) were collected from slaughterhouses in Hangzhou to determine the prevalence and antimicrobial susceptibility patterns of Salmonella. Isolates were characterized by serotyping, PFGE (Pulsed-field gel electrophoresis), Polymerase chain reaction (PCR), and antibiotic susceptibility testing. The rates of Salmonella-positive pork, chicken, and goose samples were 21.1% (n = 59), 10.4% (n = 25) and 10.0% (n = 6), respectively. The prevalence of Salmonella was 15.5% in slaughterhouses. Thirteen different Salmonella serovars were identified, and 6 isolates could not be identified. The most commonly prevalent serovars are Salmonella Rissen (S. Rissen) (n = 20, 22.2%), S. Derby (n = 16, 17.8%) and S. Typhimurium (n = 12, 13.3%). The detection rate of the remaining serovars ranged from 1.1%-11.11%. All Derby, Corvallis, and Kentucky strains were from pork. Seventy-two isolates (80.0%) showed drug resistance (DR) to at least one antibiotics, 19 (21.1%) were multi-drug resistant strains, 2 (2.2%) showed seven or more. The detection rate of Trimethoprim/Sulfamethoxazole-resistance (70.0%) was highest, followed by Ampicillin (55.6%). Salmonella resistance was found related to serovar and origin. The positive rates of DR gene sul1, sul2, sul3, class I integrons and bla were 92.2%, 95.6%, 86.7%, 83.3% and 62.2%, respectively. Fifty-seven different PFGE patterns and 7 main clusters were obtained. This study revealed the high positive rates of Salmonella resistance and related DR genes, especially for Sulfamethoxazole-resistance and its related gene.

Introduction: is an important foodborne pathogen that can induce severe diseases such as gastrointestinal disease and typhoid fever. Accumulating evidence revealed that 's resistance to antibiotics also seriously affects human health. Pathogenic serovar Goldcoast ( Goldcoast) was first detected in 2010 in China and was predicted to have an increasing tendency.

While salmonellosis is commonly thought to predominantly impact the gastrointestinal system, bacteremia and localized extraintestinal infections such as meningitis, empyema, and pericarditis can develop, particularly in immunocompromised individuals. Here, we present a case of a 69-year-old with multiple comorbidities, who presented to the emergency department with dyspnea and hemodynamics instability in the form of hypoxia and hypotension and was found to have moderate pericardial effusion without echocardiographic signs of tamponade. The ischemic workup was unrevealing, and further infectious workups, including pericardial tissue biopsy and pericardial fluid culture, showed growth in groups C and D.

Biosensors are innovative and cost-effective analytical devices that integrate biological recognition elements (bioreceptors) with transducers to detect specific substances (biomolecules), providing a high sensitivity and specificity for the rapid and accurate point-of-care (POC) quantitative detection of selected biomolecules. In the meat production chain, their application has gained attention due to the increasing demand for enhanced food safety, quality assurance, food fraud detection, and regulatory compliance. Biosensors can detect foodborne pathogens (, , Shiga-toxin-producing /STEC, , etc.

Seeds are a major source of contamination by foodborne pathogens such as , , and , significantly increasing the risk of foodborne diseases associated with fresh produce like sprouts. In this study, we described novel endolysins and the engineered variants that exhibited potent bactericidal activity against these pathogens. These endolysins demonstrated strong bactericidal effects independently of outer membrane permeabilizers, effectively killing , , and to undetectable levels (>4-log kill) at concentrations as low as 12.

Non-typhoidal salmonellosis (NTS) caused by multidrug-resistant (MDR) is a significant public health concern worldwide. Probiotics offer a potential alternative to antibiotics in many infectious diseases, including NTS. However, using living bacteria raises safety concerns in clinical settings, especially in the immunocompromised host.
