{"pk":41247,"title":"Variability of direction of tree-to-tree spread of HLB over time","subtitle":null,"abstract":"Candidatus\n Liberibacter americanus and \nCandidatus \nLiberibacter asiaticus are two bacterial species that cause huanglongbing (HLB) disease in citrus-growing regions of Brazil. A concentrated sampling plan of a grove in Matao, Brazil was initiated to evaluate the spatial and temporal spread of these bacteria. The exact location of each of 8697 trees was recorded, and each symptomatic tree was assessed by PCR for the presence of \nCa\n. L. americanus and \nCa\n. L. asiaticus during 17 different months from April 2006 to May 2008 (Fig. 1). In the first month, only five trees were confirmed to have \nCa\n. L. asiaticus. The first trees with confirmed cases of \nCa\n. L. americanus were not found until February 2007. By the end of the study, 43 trees were confirmed to have \nCa\n. L. americanus, 1164 trees were confirmed to have \nCa\n. L. asiaticus, and three trees were coinfected.","language":"en","license":{"name":"Creative Commons Attribution 4.0","short_name":"CC BY 4.0","text":"Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.
