Salmonella in poultry is one of the most critical zoonotic diseases worldwide, posing serious risks to food safety, public health, and poultry production. In the EU, over 65,000 human Salmonellosis cases were reported in 2022, with actual infections likely much higher. The most common serovars—Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST)—are often linked to eggs and poultry meat, making Salmonella control in poultry farms essential. Transmission occurs both horizontally (via contaminated
feed, water, and equipment) and vertically (through infected eggs), creating challenges for breeders and hatcheries. Effective Salmonella prevention requires strict biosecurity measures, routine environmental monitoring, and vaccination programs to reduce infection rates and protect consumer health. As part of the One Health approach, controlling non-typhoidal Salmonella in poultry is vital to safeguard flocks, maintain compliance with EU Salmonella regulations, and protect poultry brands from costly outbreaks.

Newcastle disease is caused by a virus belonging to the family of Paramyxoviridae; it is an avian paramyxovirus of serotype 1 (APMV-1). It affects wild birds and
domestic poultry and usually presents as a respiratory disease. Depression, nervous manifestations, or diarrhea may also be the predominant clinical symptoms and mortality.

Gumboro disease, also known as infectious bursal disease (IBD), is a highly contagious disease of young chickens. Today, the very virulent
form is predominant in most countries, and variant strains of IBD are present in several countries, leading to sub-clinical forms of the disease.

Avian Infectious Bronchitis (IB) is a highly contagious viral disease of chickens, caused by a gamma-coronavirus. It affects respiratory, urinary and reproductive systems, and
can result in respiratory distress, reduced growth, poor feed conversion, and in layers, serious damage to the oviduct ; leading to lower egg production and degraded egg quality.

Coccidiosis is a parasitic disease of poultry caused by protozoans of the genus Eimeria, affecting mainly chickens and turkeys. It impacts the intestinal tract, leading to poor feed conversion, slowed growth, higher mortality, and substantial economic losses worldwide.
While anticoccidial drugs (ionophores, chemicals) have long been standard for prevention, vaccination is increasingly adopted as a more sustainable and effective control method.
