Burkholderia vietnamiensis causing infections in noncystic fibrosis patients in a tertiary care hospital in Mexico.

Burkholderia cepacia complex (Bcc) species are opportunistic pathogens widely distributed in the environment and often infect people with cystic fibrosis (CF). This study aims to determine which genomovars of the Bcc can cause infections in non-CF patients from a tertiary care hospital in Mexico and if they carry virulence factors that could increase their pathogenicity. We identified 23 clinical isolates that carry the recA gene.

Fibrosis quística: patogenia bacteriana y moduladores del CFTR (regulador de conductancia transmembranal de la fibrosis quística).

Cystic fibrosis is an autosomal recessive inherited disease caused by mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR). CFTR is a protein that transports ions across the membrane of lung epithelial cells. Loss of its function leads to the production of thick sticky mucus, where various bacterial pathogens can establish and adapt, contributing to the gradual loss of lung function.

Bacterial Subversion of Autophagy in Cystic Fibrosis.

Cystic fibrosis (CF) is a genetic disease affecting more than 70,000 people worldwide. It is caused by a mutation in the gene, a chloride ion transporter localized in the plasma membrane of lung epithelial cells and other organs. The loss of CFTR function alters chloride, bicarbonate, and water transport through the plasma membrane, promoting the production of a thick and sticky mucus in which bacteria including and can produce chronic infections that eventually decrease the lung function and increase the risk of mortality.

Pseudomonas Aeruginosa: Genetic Adaptation, A Strategy for its Persistence in Cystic Fibrosis.

Cystic fibrosis (CF) is a progressive autosomal recessive genetic disease that principally affects the respiratory and digestive systems. It is a chronic disease that has no cure. Symptoms often include chronic cough, lung infections, and shortness of breath.
