Primary study on Melioidosis due to Burkholderia pseudomallei in pig in Nghe An province

Abstract

Melioidosis (or Whitmore disease) is a serious, acute disease, infecting not only in animals such as: goat, sheep, pig, horse, mice, dog, buffalo, cow, bear… but also in human; This disease is caused by the Burkholderia pseudomallei bacterium. To investigate the Burkholderia pseudomallei infection in pigs, 219 samples, including blood, lung tissues, urine samples from the slaughterhouses, pharyngeal swab, urine, abscess samples from the commercial pig farms and household pig farms in 4 districts and 10 communes of Nghe An province were collected in August and October 2016. The result  of culturing, isolation and bacteria strain identification  in the laboratory showed that there was 1 pharyngeal swab sample (out of 219 samples) from the 2nd batch in October  detected to be positive with Burkholderia pseudomallei (accounting for 0.46%). The result of antibiotic sensitivity test showed that this bacterium was highly susceptible with amo+a.clavulanic, ciprofloxacin, chloramfenicol, tetracylin, mildly susceptible with  kanamycin, completely resistant  to gentamycin, colistin and meet the resistant standards to ceftazidim
