Sir,

We read the article, “Myroides odoratus central nervous infection in a postneurosurgery patient” on the esteemed “Indian Journal of Medical and Paediatric Oncology” with great interest. Bhat et al. reported a case of meningitis secondary to M. odoratus followed by supratentorial craniotomy due to a recurrent right frontal malignant brain tumor that arises from astrocytes.[1]

M. odoratus and Myroides odoratimimus are two important species of the Flavobacteriales order that cause infections in humans.[2] In this context, pericardial effusion, pericarditis, pneumonia, soft tissue infection, septic shock, and urinary tract infection were already associated with these microorganisms. However, neurological infections were rarely reported in literature.[3]

Here, we would like to provide a comparison between the two causes already published in the literature [Table 1].[1],[4] An interesting fact to be highlighted is that even though Myroides species infections are one of more resistant organisms in literature, in majority of the reports the individuals had full recovery.[3]

A recent article by Hu et al. revealed that the comparative analysis of some Myroides strains is phylogenetically related with similar genomes. Furthermore, their study showed that clustered regularly interspaced short palindromic repeats were found in two of the organisms. Thus, these results substantially contribute to a better understanding of the bacterial pathogenicity and antibiotic resistance mechanisms of this genus.[5]
