| Resumo: |
ABSTRACT Fowl Cholera (FC) is a disease caused by Pasteurella multocida. The severity of this disease is partly caused by virulence factors. Genes encoding fimbriae, capsule, sialidases and proteins for iron metabolism may be related to P. multocida’s ability to infect the host. Besides to examining DNA for the presence of virulence genes, DNA is essential for the diagnostic and FTA cards are an alternative for genetic material transport. The study aims to evaluate the viability of P. multocida DNA transport using the cards and to detect 14 virulence genes in 27 strains isolated from FC cases in the United States by multiplex-PCR. No growth was observed in any of the FTA cards, which was essential to assess the security. Furthermore, DNA detection was possible in 100% of the samples, independent of the storage period (7 to 35 days) and temperature (4°C and 37°C). ptfA, exbd-tonB, hgbA, nanB, oma87, hyaD-hyaC, sodC, hgbB, sodA, nanH and pfhA genes were detected in more than 80% of the samples. FTA cards have proven to be a viable and safe tool for DNA transport of P. multocida. A majority of genes showed a high frequency, which was similar to strains isolated from FC cases.
