Salmonella remains a primary cause of zoonotic foodborne disease. This makes the search for effective Salmonella antibiotic alternatives a public health priority. Specifically, avian strains like S. Pullorum cause high mortality in chicks. Meanwhile, paratyphoid strains contaminate the human food chain. Consequently, overusing antibiotics in poultry has led to widespread multi-drug resistance. Therefore, clinicians must understand how non-drug interventions in farming impact human health.
Probiotics and phytobiotics represent promising tools to enhance immune responses. These additives successfully stabilize gut microbiota and reduce pathogen shedding. Additionally, bacteriophages are specific viruses that target pathogens while leaving beneficial flora intact. However, the efficacy of these treatments depends heavily on the timing and dosage. Notably, research indicates that combining multiple interventions creates a synergistic effect. Furthermore, nanoparticles and egg yolk immunoglobulins help manage persistent asymptomatic carriers. Such biocontrol measures effectively replace conventional antibiotics in therapeutic settings. Moreover, these strategies lower the risk of intestinal dysbiosis in the birds. Ultimately, these innovations support the global One Health initiative. In conclusion, adopting these alternatives ensures a safer food supply for everyone.
Probiotics enhance the immune response and help maintain a healthy gut microbiome, which prevents pathogenic Salmonella from colonizing the intestinal tract.
Yes, bacteriophages are highly specific to target bacteria and do not harm the bird's natural microflora or create the same resistance risks as antibiotics.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
