ブロイラー鶏におけるブドウ球菌属の疫学、病原性、ゲノム適応性、および同時感染

Staphylococcus species are saprophytic, opportunistic, and nosocomial pathogens that frequently co-infect with other microorganisms, causing severe infections in birds. Some of the notable examples include bacterial chondronecrosis with osteomyelitis (BCO), cellulitis, dermatitis, and systemic infections. Understanding of how Staphylococcus spp. cause infections evading the host immune system is crucial for helping farmers and veterinarians develop long-term solutions for poultry production system management. The aim of this review is to broaden the understanding of Staphylococcus spp. epidemiology, virulence, genomic adaptability and coinfection patterns. The peer-reviewed articles were obtained from various databases, including Google Scholar, Web of Science, and PubMed. The review primarily focused on papers published between 1999 and 2025. The review presents an opportunity to identify research gaps and apply this knowledge to develop innovative approaches to address staphylococcal infections in broiler chickens. Additionally, BCO is often attributed to coinfection with Staphylococcus species and other pathogens.
