Special Issue Information

Dear Colleagues,

Staphylococci are the main inhabitants of skin and mucosa of both animals and humans, in which these opportunistic Gram-positive bacteria can be responsible for a great variety of infections, including pyoderma, otitis, abscesses, mastitis, urinary tract infections, and wound infections. 

Over the last decade, both coagulase-positive Staphylococci (CoPS) and coagulase-negative Staphylococci (CoNS) have become critically opportunistic animal pathogens, frequently being the primary etiological agents of infections such as otitis and pyoderma in small animals. Furthermore, the potential zoonotic transmission of these pathogens should not be underestimated, with animals acting as reservoirs for humans.

The recent emergence and rapid dissemination of multidrug-resistant staphylococcal strains, particularly methicillin-resistant S. aureus and S. pseudintermedius, showing increasingly frequent resistance to the antibiotic agents licensed for use in small and farm animal practice, represent a relevant threat to animal and public health. In the last decade, the antibiotic resistance issue has become increasingly relevant, underlining the need of a continuous surveillance of both methicillin-resistant and methicillin-susceptible Staphylococci, as well as the development of new and alternative therapeutic options. 

This Special Issue aims at establishing a collection of papers exploring the occurrence of Staphylococcus spp. in small animals, livestock, wildlife, and humans, the pathogenic mechanisms involved in the onset of the infection, the mechanisms of antibiotic resistance, the diagnostic tools, and the new alternative treatment approaches to prevent and limit the dissemination of multidrug-resistant strains. 

We look forward to receiving research articles, review articles, and short communications on these topics that warrant further exploration.

Sternal bursitis, a common inflammatory condition in poultry, poses significant challenges to both animal welfare and public health. This study aimed to investigate the prevalence, antimicrobial resistance, and genetic characteristics of Staphylococcus aureus isolates associated with sternal bursitis in chickens. Ninety-eight samples were collected from affected chickens, and 24 S. aureus isolates were identified. Antimicrobial susceptibility testing revealed resistance to multiple agents, with a notable prevalence of aminoglycoside resistance genes. Whole genome sequencing elucidated the genetic diversity and virulence profiles of the isolates, highlighting the predominance of clonal complex 5 (CC5) strains. Additionally, biofilm formation assays demonstrated moderate biofilm production capacity among the isolates. These findings underscore the importance of vigilant monitoring and targeted interventions to mitigate the impact of sternal bursitis in poultry production systems. Full article

A novel coagulase-negative Staphylococcus strain (H164T) was isolated from soymilk in Taiwan. Comparative sequence analysis of the 16S rRNA gene revealed that the H164T strain is a member of the genus Staphylococcus. We used multilocus sequence analysis (MLSA) and phylogenomic analyses to demonstrate that the novel strain was closely related to Staphylococcus gallinarum, Staphylococcus nepalensis, Staphylococcus cohnii, and Staphylococcus urealyuticus. The average nucleotide identity and digital DNA-DNA hybridization values between H164T and its closest relatives were <95% and <70%, respectively. The H164T strain could also be distinguished from its closest relatives by the fermentation of d-fructose, d-maltose, d-trehalose, and d-mannitol, as well as by the activities of α-glucosidase and alkaline phosphatase. The major cellular fatty acids were C15:0 iso and C15:0 anteiso, and the predominant menaquinones were MK-7 and MK-8, respectively. The major cellular fatty acids and predominant menaquinones were C15:0 iso and C15:0 anteiso and MK-7 and MK-8, respectively. In conclusion, this strain represents a novel species, named Staphylococcus hsinchuensis sp. nov., with the type strain H164T (=BCRC 81404T = NBRC 116174T). Full article
