Detection of genomic Bordetella DNA by PCR. (a) A PCR product of 318 bp was amplified with B. pseudohinzii-specific primers from DNA of faeces (upper panel) and larynx (lower panel) from infected (lanes 1–4) and non-infected (lanes 5–8) mice, as classified by MALDI-TOF MS. DNA isolated from cultured B. pseudohinzii (strain 3227) served as a positive control (lane 9). Control runs without template were negative (lane 10). M: 100 bp molecular weight marker. (b) Trachea and lung taken were taken from 6 animals which were positive for B. pseudohinzii by PCR of faecal pellets, homogenized, and plated on selective agar plates. Number of colony forming units (CFU) is given per 100 mg of tissue. Individual data points shown; horizontal bar and whiskers indicate mean and standard error of the mean. Weight of tissue samples and CFU/organ are provided in Supplementary Table 1.
