RESUMO
Cross-infection with Pseudomonas aeruginosa among cystic fibrosis (CF) patients is a rare occurrence. However, the emergence of transmissible strains has been reported between unrelated individuals. We analyzed the genetic relationship among P. aeruginosa isolates from Brazilian CF patients and transmissible clones which are worldwide spread. The data does not indicate the presence of closely related variant clones.
RESUMO
Mucoid Burkholderia cepacia morphotype emerged within a nine year follow-up of a cystic fibrosis patient. Clinical data suggested a linkage between the mucoid phenotype isolation and the deterioration of the patient's condition. Despite of the phenotypic variation, molecular typing showed that the patient was chronically infected with B. cepacia complex isolates belonging to a same genetic clone.
O presente trabalho descreve a emergência de cepas mucoides do complexo B. cepacia em um paciente com Fibrose Cística dentro de um acompanhamento bacteriológico prospectivo de nove anos. Os dados clínicos sugerem a associação entre o isolamento do morfotipo mucoide e a deterioração clínica do paciente. Apesar da variação fenotípica, os testes moleculares mostraram que o paciente manteve-se cronicamente infectado por cepas de mesma origem clonal.
