“…In immunocompetent people, primary infections by Myroides sp. have been rarely reported, such as a case of M. odoratimimus cellulitis resulting from a pig bite in an immunocompetent child (Maraki et al, 2012). However, secondary infections can frequently arise when human immunity is impaired, such as post catheterization (Holmes et al, 1977;Spanik et al, 1998), in patients with cancer (Holmes et al, 1977;Spanik et al, 1998;Song, 2005) or diabetes mellitus (Yang and Wang, 2001), and in neonates (Wang and Su, 1992;Zhang and Zhang, 1996;Zhao, 2000).…”

Bacteria of the genus Myroides (Myroides spp.) are rare opportunistic pathogens. Myroides sp. infections have been reported mainly in China. Myroides sp. is highly resistant to most available antibiotics, but the resistance mechanisms are not fully elucidated. Current strain identification methods based on biochemical traits are unable to identify strains accurately at the species level. While 16S ribosomal RNA (rRNA) gene sequencing can accurately achieve this, it fails to give information on the status and mechanisms of antibiotic resistance, because the 16S rRNA sequence contains no information on resistance genes, resistance islands or enzymes. We hypothesized that obtaining the whole genome sequence of Myroides sp., using next generation sequencing methods, would help to clarify the mechanisms of pathogenesis and antibiotic resistance, and guide antibiotic selection to treat Myroides sp. infections. As Myroides sp. can survive in hospitals and the environment, there is a risk of nosocomial infections and pandemics. For better management of Myroides sp. infections, it is imperative to apply next generation sequencing technologies to clarify the antibiotic resistance mechanisms in these bacteria.

“…Although Myroides is commonly found is soil and water, the mode of acquisition in this case could not be ascertained. There was no history of animal bite, injuries or exposure to contaminated water bodies, which is often implicated as source of infection (Maraki, Sarchianaki et al, 2012). Myroides infection are rare in Indian setting and presently only few case reports are published till date (Deepa et al, 2014, Elantamilan et al, 2015, Prateek et al, 2015.…”

A 41 year old male; a known case of frontal astrocytoma was brought to this centre with history of headache, altered sensorium and an episode of seizure. He was diagnosed as a case of anaplastic astrocytoma six months back and underwent surgical resection followed by chemotherapy and radiotherapy. Clinical evaluation revealed bedridden but responsive patient with Glasgow coma scale of 6/15. Radiological investigations confirmed recurrence of lesion in right frontal lobe. He was admitted to the intensive care unit (ICU) and underwent emergent surgical resection of the tumor.The patient had a stormy post-operative course, requiring ventilatory as well as ionotropic support. Histopathological examination of the resected tumor specimen confirmed a grade III anaplastic astrocytoma. On third post-operative day, he developed continuous, moderate to high grade fever with features of hemodynamic instability. Total leucocytes count increased from 11500/cumm on first post-operative day to 16,200/cumm. Peripheral blood smear examination indicated neutrophilia with left shift and toxic granulation. Urine examination showed presence of traces of albumin, reducing substances and numerous pus cells. Blood, urine and surgical drain samples were sent to microbiology laboratory for culture and antibiotic sensitivity testing. International Journal of Current Microbiology and Applied Sciences

“…In immunocompromised patients, Myroides may be responsible for skin infections in patients with diabetes [6,7], urinary tract infections, lung infections [8][9][10], endocarditis [11], ventriculitis [12,13], bacteremia [14] or infections of the central nervous system. Rarely, there have been reported cases of infection in immunocompetent hosts [12,13]; the described cases were associated with hepatic, renal insufficiency, malignancies or co-infections with Oerskovia turbata in alithiasic cholecystitis [15].…”

“…The patient had multiple admissions, which explains antibiotic resistance of Pseudomonas aeruginosa and Proteus vulgaris isolates. However, isolated Myroides strain was sensitive to carbapenems, fluoroquinolones, minocycline and cefepime, compared to other cases cited in the literature, that generally recorded resistance to β-lactams through chromosomally encoded the subclass B1 of metallo-β-lactamases [16] or variable susceptibility to aminoglycosides or quinolones [8,12,[17][18][19][20]. Common susceptibility of isolated strains to meropenem allowed monotherapy in doses appropriate to renal impairment, recommending at discharge another 7 d of ciprofloxacin.…”
