Oral vaccination in pigs, previously limited to enteric pathogens, is emerging as an innovative strategy against respiratory diseases. By building on the potential of the Common Mucosal Immune System (CMIS), new formulations can trigger immune responses in distant mucosal sites starting from the gut.

By exploring the mechanisms of the Common Mucosal Immune System (CMIS), orally administered vaccines are capable of activating coordinated immune responses across different mucosal sites in the body. In this content, we explain how local activation in the GALT triggers protective effects in distant mucosal tissues, such as the respiratory tract, thereby expanding the reach of immune protection.

In the fourth installment of the manual, we address examining the thoracic cavity organs.

One percentage of affected lung volume was associated with a 0.24% reduction in lean meat content.

How do turbinate atrophy and the effect on cilia caused by B. bronchiseptica affect the incidence of S. suis and porcine respiratory disease complex?

Detection of lung lesions in slaughtered pigs also allows estimation of economic losses.

What laboratory diagnostic methods can I use to APP? Which one should I choose according to the situation? How do I interpret the results?

Side effects of perinatal medications on the microbiota can be detrimental to animal health.

Collecting data at the slaughterhouse is a common method to obtain information on health and productive parameters, mainly from the last weeks of a pig’s life.

This PRRSV strain is affecting the U.S. Understanding where these viruses come from can help us stop this cycle.

The influenza virus promotes colonization by secondary bacterial agents in the lung, facilitating their passage into the bloodstream.

In this article we summarize further discussions that we had with Dr. Nauwynck about his research findings on PRRS virus-host evolution.

Dr. Hans Nauwynck, a well-known professor at the University of Ghent, reviews with us the most important findings that he has made in PRRS virus research since it was first discovered 30 years ago.

What is the actual effect of pneumonia on the farm's economic performance? What similarity is there between pneumonia and heat stress?

M. hyopneumoniae is involved in most of the co-infections of the porcine respiratory system. How does it act and what effects does it have?

Respiratory pathogens produce different coughs. Any coughing by pigs in a grow-out barn can vary according to the infection present, so it is worthwhile to listen carefully.
