Genomic insight into Myroides oncorhynchi sp. nov., a new member of the Myroides genus, isolated from the internal organ of rainbow trout (Oncorhynchus mykiss)

The strain M-43^T was isolated from the Oncorhynchus mykiss from a fish farm in Mugla, Turkey. Pairwise 16S rRNA gene sequence analysis was used to identify strain M-43^T. The strain was a member of the genus Myroides sharing the highest 16S rRNA gene sequence identity levels of 98.7%, 98.3%, and 98.3% with the type strains of M. profundi D25^T, M. odoratimimus subsp. odoratimimus CCUG 39352^T and M. odoratimimus subsp. xuanwuensis DSM27251^T, respectively. A polyphasic taxonomic approach including whole genome-based analyses was employed to confirm the taxonomic provenance of strain M-43^T within the genus Myroides. The overall genome relatedness indices (OGRI) for strain M-43^T compared with its most closely related type strains M. odoratimimus subsp. xuanwuensis DSM 27251^T, M. profundi D25^T, and M. odoratimimus subsp. odoratimimus ATCC BAA-634^T, were calculated as 25.3%, 25.1%, and 25% for digital DNA-DNA hybridization (dDDH), 83.3%, 83.6%, and 83.4% for average nucleotide identity (ANI) analyses, respectively. The OGRI values between strain M-43^T and its close neighbors confirmed that the strain represents a novel species in the genus Myroides. The DNA G + C content of the strain is 33.7%. The major fatty acids are iso-C_15:0 and summed feature 9 (iso-C_17:1 ω9c and/or 10-methyl C_16:0). The predominant polar lipids are phosphatidylethanolamine, an amino-lipid and five unidentified lipids. The major respiratory quinone is MK-6. Chemotaxonomic and phylogenomic analyses of this isolate confirmed that the strain represents a novel species for which the name Myroides oncorhynchi sp. nov. is proposed, with M-43^T as the type strain (JCM 34205^T = KCTC 82265^T).

Rubinstein Taybi syndrome with hepatic hemangioma

OBJECTIVE

It was the aim of our study to present a case of Rubinstein Taybi syndome (RTS) associated with hepatic hemangioma.

CLINICAL PRESENTATION AND INTERVENTION

A 6.5-year-old boy was diagnosed with RTS. He had large areas of cutaneous capillary hemangiomas. Radiological examination revealed a hepatic hemangioma. A multidisciplinary follow-up program was commenced and hepatic ultrasound examinations were performed periodically. No progression and complication have since occurred.

CONCLUSION

This case shows an association between RTS and hepatic hemangioma, and hence, we recommend regular hepatic ultrasound examination when RTS is suspected or diagnosed.
