“…They can withstand stomach acid, increase antigen-presenting cell uptake, stimulate the immune system continuously and act as adjuvants [143]. Silver nanoparticles act as carriers of plant extracts, antibiotics, or vaccines which are delivered on attachment to the cell membrane of Salmonella leading to microbial dysfunction [144].…”

Salmonella - Current Trends and Perspectives in Detection and Control

Salmonella belonging to the Enterobacteriaceae family is commonly divided into Typhoidal and non-typhoidal group. Clinical manifestations can range from gastroenteritis, bacteremia or septicemia without gastrointestinal (GI) upset, enteric fever, chronic carriage to focal infections like osteomyelitis, meningitis, endocarditis etc. Conventional diagnostic tests like blood, stool, food sample culture have a long turnaround time. Chromogenic media modification reduces identification time. Apart from Widal test and ELISA, rapid point of care serological tests like Tubex TF, Typhidot are advantageous in basic set up but limited by modest accuracy in high burden settings. Apart from immunological assays, other diagnostic modalities include PCR, mass spectrophotometry, spectroscopy, optical phenotyping, biosensors etc. Rising drug resistance of Salmonella to first line Ampicillin, Chloramphenicol and Cotrimoxazole with increasing nonsusceptibility to fluoroquinolones and 3rd generation cephalosporin for past few decades is a public threat. Prevention and control measures include basic sanitation, safe water access, safe food handling, public education, physical, chemical, biocontrol methods, vaccination etc. Targeting the menace of antimicrobial resistance in Salmonella species needs a collaborative effort like One Health approach which optimizes the public health, animal and environmental health and reduce the dependency on antibiotics.

“…In fighting against diseases, NPs are used as a carrier of plant extracts, antibiotics, or vaccines and enhance mobilization to the target area of infection inside the host. The study by [ 275 ] observed that AgNP mediated by Ferula ovina Boiss extract was more effective against Gram-negative S. Typhimurium and E. coli in vitro using the disk diffusion method. The more bactericidal effect of AgNPs is enhanced by their small size, which provides a larger surface area for interacting with the bacterial cell membrane.…”

Salmonella is a foodborne zoonotic pathogen causing diarrhoeal disease to humans after consuming contaminated water, animal, and plant products. The bacterium is the third leading cause of human death among diarrhoeal diseases worldwide. Therefore, human salmonellosis is of public health concern demanding integrated interventions against the causative agent, Salmonella enterica. The prevention of salmonellosis in humans is intricate due to several factors, including an immune-stable individual infected with S. enterica continuing to shed live bacteria without showing any clinical signs. Similarly, the asymptomatic Salmonella animals are the source of salmonellosis in humans after consuming contaminated food products. Furthermore, the contaminated products of plant and animal origin are a menace in food industries due to Salmonella biofilms, which enhance colonization, persistence, and survival of bacteria on equipment. The contaminated food products resulting from bacteria on equipment offset the economic competition of food industries and partner institutions in international business. The most worldwide prevalent broad-range Salmonella serovars affecting humans are Salmonella Typhimurium and Salmonella Enteritidis, and poultry products, among others, are the primary source of infection. The broader range of Salmonella serovars creates concern over multiple strategies for preventing and controlling Salmonella contamination in foods to enhance food safety for humans. Among the strategies for preventing and controlling Salmonella spread in animal and plant products include biosecurity measures, isolation and quarantine, epidemiological surveillance, farming systems, herbs and spices, and vaccination. Other measures are the application of phages, probiotics, prebiotics, and nanoparticles reduced and capped with antimicrobial agents. Therefore, Salmonella-free products, such as beef, pork, poultry meat, eggs, milk, and plant foods, such as vegetables and fruits, will prevent humans from Salmonella infection. This review explains Salmonella infection in humans caused by consuming contaminated foods and the interventions against Salmonella contamination in foods to enhance food safety and quality for humans.

“…Rancing) [3], and Ferula ovina Boiss. [7] have been explored to produce AgNPs with excellent antibacterial activity and extremely small nanoparticle sizes below 17 nm. Although many plants are already exploited for the green synthesis of AgNPs, there are plenty of unexplored plants that might offer unique characteristics.…”

Silver nanoparticles (AgNPs) are fascinating materials for biomedical applications thanks to their strong antibacterial activity and biocompatibility. This study applied the green synthesis method using 0.5 wt.% Seminyak leaf extract and assisted with one min microwave irradiation to enhance AgNPs formation. Extremely small sizes AgNPs with an average particle size of 9.1 ± 4.1 nm and spherical shapes were obtained. The synthesized AgNPs displayed potent antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria with a zone of inhibition of 12.3 ± 0.1 and 13.7 ± 0.7 mm, respectively. The MTT assay results demonstrated that the cells’ viability of the obtained AgNPs was 88.5 ± 7.0 %, implying biocompatibility for biomedical applications.
