Isolation Of Actinobacillus Pleuropneumoniae Serotype 15-Like Strain From A Porcine Tonsil In Thailand: A Case Report, Walaiporn Tonpitak
The Thai Journal of Veterinary Medicine
An isolate of Actinobacillus (A.) pleuropneumoniae from porcine tonsil samples was identified as serotype 15-like strain, which was previously isolated in Australia, North America and Japan. It was characterized by biochemical testing performed for Actinobacillus sp. and confirmed as A. pleuropneumoniae by PCR and nucleotide sequencing of 16s rDNA. The isolate contains apxIBD, apxIICA, apxIIIBD, apxIIICA and apxIVA gene. The result of PCR-REA of apxIVA method was identical as A. pleuropneumoniae serotype 15 strain HS143 reference strain. Therefore this isolate is proposed as A. pleuropneumoniae serotype 15- like strain and the first report of A. pleuropneumoniae serotype 15-like strain in …

This experiment was performed to study gross and microscopic lung lesions after endotracheal inoculation with Actinobacillus pleuropneumoniae (A. pleuropneumoniae) serotype 1 in twenty-four guinea pigs. Four-six hours post inoculation, clinical signs of respiratory distress and epistasis were observed. Most of the infected animals suddenly died during this time. The differences between the pulmonary lesions were evaluated. In this experiment, the lesions of peracute infection by A. pleuropneumoniae were induced within 4-6 hours and the lesions of subacute infection, characterized by fibrinopurulent pleuritis were observed in surviving animals 18-20 hours post inoculation. The results suggested that guinea pigs could be used …
