Abstract The objective of the study was to determine genotypic profiles of Bordetella bronchiseptica (Bbr) strains, based on the occurrence of genes encoding virulence factors, such as flagella (fla), dermonecrotoxin (dnt), and exogenous ferric siderophore receptor (bfrZ), using PCR. 209 tested Bbr strains were obtained from Polish swine herds with different health status (with progressive atrophic rhinitis - PAR, suspected for PAR, and unknown). In total, seven different Bbr genotypes were determined. In 39.2% of Bbr isolates all three genes were present. In 41.1% of the isolates only two genes were detected. The most common genotype dnt+bfrZ-fla+ was present in 60 (28.5%) Bbr strains, 65% of them were obtained from farms with PAR. Twenty five (12%) Bbr isolates were identified as dnt-bfrZ+fla+ genotype and, as above, they were more frequently isolated from clinical cases of disease (84%). Among 31 (14.8%) strains only fla gene was evident, and in nine (4.3%) only dnt gene was present. There were no Bbr strains with bfrZ gene only. These results confirm the heterogenicity among Bbr strains.

Ninety-six nasal isolates of Pasteurella multocida from swine herds with progressive atrophic rhinitis were characterized by restriction endonuclease analysis (REA) of whole-cell DNA, ribotyping, and plasmid analysis. For REA, bacterial DNA was digested with SmaI and electrophoresed in 0.7% agarose, and fragments were visualized with UV light. For ribotyping, EcoRI-digested and electrophoresed restriction fragments of whole-cell DNA were transferred to nitrocellulose membranes, hybridized with γ-32P-labeled Escherichia coli ribosomal RNA, and visualized by autoradiography. Phenotypes of isolates were toxigenic capsular type D ( n = 51), nontoxigenic type D ( n = 28), nontoxigenic type A ( n = 16), and toxigenic type A ( n = 1). Plasmids of various sizes were evident in 92.2% and 17.9% of toxigenic and nontoxigenic D strains, respectively, but were absent from all type A strains. Among the 4 phenotypes, there were 17 REA profiles and 6 ribotypes. For 3 of 17 REA patterns, multiple ribotypes were evident, and several REA types were evident in 5 of 6 ribotypes. Thirty-seven isolates of toxigenic capsular type D from Australian herds were either SmaI type B or C and ribotype 2, whereas 14 toxigenic D isolates from the USA and other countries were more heterogeneous (7 REA types and 6 ribotypes). The fingerprinting results provided evidence in support of the hypothesis of a single source infection in Australia associated with the introduction of breeding pigs from overseas.

Susceptibility Profiles

Background: Pasteurella multocida (Pm) is the causative agent of progressive atrophic rhinitis (PAR) and pneumonic pasteurellosis (PN) in pigs. Pm is a member of the porcine respiratory complex responsible for important economic loss in the pig industry. Aim: This study aimed to characterize the Pm strains recovered from clinical cases of PN and PAR and to elucidate the antibiotic susceptibility profiles of the strains. Materials and Methods: Sixty strains were characterized molecularly by polymerase chain reaction to determine species-specific gene, capsular type (A or D), and toxin A production. The agar diffusion method was employed to evaluate antibiotic resistance profiles. Results: We found that 65% of strains belonged to capsular type A or D, and 15% of those were positive to toxA gene. The antibiotic susceptibility profiles found were sensitive in decreasing order to: Enrofloxacin, ceftiofur (CTF), ampicillin, tilmicosin (TIL), florfenicol (FFN), spectinomycin (SPC), gentamicin, oxytetracycline (OTC), and trimethoprim-sulfamethoxazole (TMS). Strains were resistant in decreasing order to: Lincomycin (LIN), tylosin (TYL), erythromycin (ERY), TMS, SPC, OTC, FFN, TIL, and CTF. Conclusion: The toxA gene was detected in many Pm isolates from pneumonic lungs. Capsule type A or D was the most frequently found among the collected isolates. LIN, TYL, and ERY are the drugs which showed higher percentages of resistant isolates.
