Chicken could be a self-sustaining reservoir of Streptococcus suis (S. suis) to human and pigs in contact, according to a study recently been published in the Zoonoses and Public Health journal. This organism is well-known as a global pathogen of pigs as well as an emerging zoonotic pathogen that causes severe human diseases. The study, led by Ms. Nguyen Thi Nhung (PhD student, Open University, UK), investigated 59 healthy chicken flocks and 44 in-contact pigs between February and July 2018. Among those, S. suis was isolated from 33.9% chicken flocks and in all pigs. At genetic level, most chicken S. suis were different from human and pig isolates, as well as in terms of their antimicrobial resistance pattern. However, 10% of chicken isolates investigated were identical to pig isolates in the same area, confirming the capacity of chickens of hosting and potentially spreading the organism to humans and to pigs. Results from this study should help increase awareness of good farming practices to limit transmission of S. suis from animals to humans. Download here
