Streptococcus suis avian expansion suggests shared antibiotic use drives host jumps.

ABSTRACT:

Background

The interconnectedness of human, animal, and environmental health drives emerging threats, such as antimicrobial-resistant pathogens. The widespread use of the same antimicrobials in both human and livestock may play a role in interspecies bacterial transmission by disrupting natural microbial communities and creating an environment favouring resistant bacteria. Pigs and poultry receive high levels of antimicrobials and are reservoirs of multidrug-resistant bacteria, including Streptococcus suis, a zoonotic pig pathogen. S. suis detection in non-porcine hosts, particularly poultry, raises a critical question: is this due to transient spillover or does it represent sustained host jumps and adaptation?
