Indian Journal of Medical Microbiology ¦ Volume 35 ¦ Issue 2 ¦ April-June 2017 317 Dear Editor, We read with interest the article “noncatheter-related bacteraemia due to Chryseobacterium indologenes in an immunocompetent patient” by Baruah et al. in the current issue of the Indian Journal of Medical Microbiology.[1] The authors have done the antimicrobial susceptibility using disk diffusion testing. Similarly, in a case of isolation Chryseobacterium spp. from pyonephrosis and urinary tract infection, disk diffusion was done for antimicrobial susceptibility.[2,3] The disk diffusion method is not the reliable method for testing in Chryseobacterium spp.[4] Furthermore, there are no breakpoints mentioned for Chryseobacterium spp. in Clinical and Laboratory Standards Institute guidelines and it currently does not recommend the disk diffusion testing for these organisms.[5]
