Struggling to control Streptococcus suis disease in the context of antibiotic reduction
Published: August 4, 2021
Summary
Introduction Streptococcus suis (S. suis) is a major porcine pathogen responsible for important economic losses to the swine industry. In fact, it is one of the main causes of bacterial death in post-weaned piglets, from 5 to 10 weeks of age. According to the Canadian Swine Health Information Network, S. suis-related diseases are the most common infectious problem reported i...

In weaning, after a first phase where innate immunity through phospholipase2A is activated, the inflammatory process follows after 5-7 days through type 2 microfold (M2) an immunorepression of inflammatory cytokinins and activation of Treg cells with an increase of Il 10, then a decrease of neutrophil granulocytes and phagocytosis. At the same time at the microbiome level there is a decrease in bacterioides and an increase in firmicutes (lactobacilli and clostridiacae). Since the clinical manifestations of Streptococcus suis infection often occur after the first post weaning week, is a link possible?

I would be interested to see the results of a comparative analysis of the microbiome of piglets given antibiotics, versus controls and the incidence of S. suis in these two groups.
