Maximum-likelihood tree, generated based on cgSNPs called by Snippy. Strains from Pakistan are printed in bold with the district of isolation given after the name (LHR—Lahore; FSD—Faisalabad; AZK—Azad Jammu and Kashmir; ISB—Islamabad; SGI—Sargodha) and the year of isolation indicated by color. For non-Pakistani strains, the country of isolation is given. The bar indicates base substitutions per site. Clusters formed by Pakistani strains are denoted by Roman numerals. Numbers in red represent bootstrap support values.
