Ca. Liberibacter americanus
Symptoms of huanglongbing (HLB) were reported in São Paulo State (SPS), Brazil, in March 2004. In Asia, HLB is caused by ‘Candidatus Liberibacter asiaticus' and in Africa by ‘Candidatus Liberibacter africanus’. Detection of the liberibacters is based on PCR amplification of their 16S rRNA gene with specific primers. Leaves with blotchy mottle symptoms characteristic of HLB were sampled in several farms of SPS and tested for the presence of liberibacters. ‘Ca. L. asiaticus' was detected in a smal
