|
Source name |
tracheal carina
|
Organism |
Sus scrofa |
Characteristics |
genotype: CFTR-/- infection: Non infected Sex: M tissue: tracheal carina
|
Treatment protocol |
Infection protocol: CFTR-/- and CFTR+/+ weighing 1 ± 0.2 kg were anesthetized with isoflurane (Vetflurane®). The trachea of each pig was then intubated and ventilated mechanically with a Fabius® Tiro® Ventilator (Dräger, Telford, USA). The ventilator settings were: volume controlled mode, tidal volume = 8-10 mL.kg-1, positive end-expiratory pressure = 5 cmH2O, respiratory rate = 15 breath.min-1, and inspiratory/expiratory ratio = 0.5, 50% oxygen in air. Piglets were inoculated with 2 mL of a suspension of luminescent P. aeruginosa strain PAKlux (5 x 10^6 cfu/mL) into the carina of trachea using an esophageal probe. Piglets were ventilated mechanically and monitored during the whole procedure and sacrificed 6 hours after infection.

Growth protocol |
All experiments were conducted in accordance with the guidelines of the Institutional Animal Care and Use Committee at INRA. The protocol was approved by the French “Ministère de l’éducation nationale, de l’enseignement supérieur et de la recherche” (n° 1166-2015071615392426). Male and female CFTR+/- transgenic pigs were provided by the LMU Munich, Germany (Klymiuk, Mundhenk et al., 2012), transferred to INRA, Nouzilly (France) and mated to generate CFTR+/+, CFTR+/- and CFTR-/- (CF) piglets. Piglets were allowed to suckle colostrum and genotype was confirmed by multiplex PCR as described below. All experiments were performed within 12 hours of birth. Non-infected newborn piglets were sacrificed by electronarcosis followed by exsanguination in the experimental slaughterhouse. Newborn piglets infected by P. aeruginosa were sacrificed by an i.v. overdose of pentobarbital (Dolethal, Vétoquinol, France) and exsanguinated before collection of post-mortem samples.

Data processing |
Mapping with STAR_2.4.0a versus Sscrofa10.2 and Pseudomonas_aeruginosa_PAK_518 genome Read counting with featureCounts (subread-1.4.6-p1-Linux-x86_64) with "--primary -g gene_name -p -s 1 -M " options Statistical analysis performed on Sus scrofa genes only. Genes which did not have at least 5 counts in at least 2 samples were filtered out. Normalization performed with DESeq2 Genome_build: Scrofa10.2 Supplementary_files_format_and_content: Matrix of normalized counts with genes as rows and sample as columns.
