Porcine Campylobacteriosis

Campylobacter hyointestinalis is a Gram-negative bacterium recognized as a significant pathogen in swine production. It is important to clarify that this organism is an animal health concern rather than a plant disease, causing intestinal infections that impact the performance of livestock.

The bacterium is primarily associated with proliferative enteropathy in pigs. It infects the lining of the small and large intestines, triggering excessive cell proliferation that disrupts the normal digestive process and severely hinders the absorption of nutrients essential for growth.

The symptoms of the infection often manifest as chronic diarrhea, gradual weight loss, and stunted growth. Infected animals may also exhibit general lethargy and a rough hair coat, which are indicators of chronic systemic stress caused by the malfunctioning gastrointestinal tract.

The development and spread of Campylobacter hyointestinalis are heavily influenced by housing conditions and biosecurity protocols. The disease spreads primarily through the fecal-oral route, with contaminated feed, water sources, and improper cleaning of animal housing acting as the main vectors for transmission.

Effective control strategies require a rigorous approach to farm biosecurity and animal husbandry. Key measures include:

• Implementing strict sanitation and disinfection schedules.
• Managing stocking density to reduce stress.
• Providing access to clean water and balanced nutrition.
• Isolating infected animals to prevent herd-wide outbreaks.
