First glanders cases detected in Nepal underscore the need for surveillance and border controls

Abstract

Abstract Background Glanders is a transmissible zoonotic disease caused by Burkholderia mallei that infects equids and humans. No glanders cases in equids were reported so far in Nepal. Case presentation Following suspected glanders in animals with clinical signs in different regions in Nepal, serum samples were tested by CFT, ELISA and Luminex® tests. Two horses and a mule tested positive for glanders by all tests, while two other equids only tested positive by ELISA and Luminex®. Analysis of swabs and pus samples by a PCR system targeting B. mallei confirmed the presence of the bacterium in the samples collected from the 3 equids that yielded positive results in all serological tests. Genotyping of the three PCR positive samples with a SNP-based method identified a genotype closely related to the B. mallei strains circulating in India. Conclusion Confirmation of glanders cases underscores the need of implementing a surveillance program in Nepal and a strict control of the animal movement across the borders.
