High Prevalence of Livestock-Associated Methicillin-Resistant Staphylococcus aureus in Hungarian Pig Farms and Genomic Evidence for the Spillover of the Pathogen to Humans

Figure 1

Location of farms and geographical origin of human clinical livestock-associated methicillin-resistant Staphylococcus aureus isolates involved in the study. Farms (F, blue circle) and places of origin of human clinical isolates (N, red circle) are numbered as referred to in the text. Counties are shaded according to the number of sows in the year 2019: 20,000–32,000 (dark grey); 10,000–20,000 (medium grey); 5,000–10,000 (light grey); and 1,000–5,000 (white).
