‘Candidatus Phytoplasma spp.’ are pathogenic bacteria that infect many plant species. ‘Candidatus Phytoplasma pyri’, one of the members of the 16SrX group causes pear decline disease that adversely affects pear crops. To describe the prevalence of ‘Ca. P. pyri’ genotypes in the Czech Republic, 143 pear samples were collected from 41 locations including commercial orchards as well as trees along roads. Phytoplasma was detected by PCR in 115 samples, and it was possible to determine imp gene genot
