Molecular characterization of Pasteurella multocida isolates from swine lungs by Randomly Amplified Polymorphic DNA
ABSTRACT: Swine respiratory diseases such as atrophic rhinitis and bronchopneumonia caused by Pasteurella (P.) multocida cause important economic losses to the modern swine industry. The purpose of this study was to characterize P. multocida strains isolated from swine lungs by RAPD (Randomly Amplified Polymorphic DNA) to demonstrate their genetic diversity. Ninety-four samples of fragments from lungs with pneumonia and sixty one samples without pneumonia were collected in slaughterhouses in Mato Grosso during the period from December 2009 to March 2010. Clinical cases in 2012 and 2013 were also included in this study. Among the lung fragments with macroscopic lesions, without macroscopic lesions and clinical samples, 40.42%, 4.49% and 100% were positive for P. multocida, respectively. Bacterial identification culturing was confirmed by PCR (polymerase chain reaction) by means of the amplification of the gene kmt1. RAPD technique was performed for 46 isolates, and in every isolate, a total of 7 to 11 amplification bands were detected, composed of 8 clusters based on genetic similarity. Thus, treatment, control and preventive measures should consider the genetic diversity of P. multocida populations in swine herds in order to improve the development of new protocols to produce antimicrobials and vaccines.
