Abstract
Objectives: Serratia marcescens is a neglected opportunistic pathogen of public-health concern, especially due to its antimicrobial resistance features. Here we report the draft genome sequence of the first KPC-2 and SRT-2 co-producing S. marcescens strain (UCO-366) recovered from a catheter tip culture of a hospitalised patient in Santiago, Chile, in 2014. Methods: Whole genomic DNA of strain UCO-366 was extracted and was sequenced using an Illumina NextSeq platform. De novo genome assembly was performed using Unicycler v.0.4.0 and the genome was annotated by the NCBI Prokaryotic Genome Annotation Pipeline (PGAP) v.4.8. Genomic features were analysed using bioinformatic tools available at the Center for Genomic Epidemiology, the Comprehensive Antibiotic Resistance Database (CARD) and Pathosystems Resource Integration Center (PATRIC). Results: The genome size of strain UCO-366 was 5 267 357 bp, with a G+C content of 59.7% and comprising 5299 coding sequences (CDS), 42 tRNAs and 115 pseudogenes. The genome of UCO-366 also included an IncL/M plasmid. The resistome comprised various antimicrobial resistance genes (ARGs) conferring resistance to carbapenems, cephalosporins, aminoglycosides, sulfonamides, chloramphenicol, rifampicin and fluoroquinolones. Importantly, S. marcescens UCO-366 harboured bla KPC-2 and bla SRT-2 , representing the first description of these ?-lactamase genes in this species in Chile. Conclusion: Here we report the genome of the first KPC-positive multidrug-resistant S. marcescens strain identi fied in Chile, which co-harboured several ARGs. The genome sequence of S. marcescens UCO-366 provides an insight into the antimicrobial resistance characteristics of this species in this country and offers important data for further genomic studies on this critical priority pathogen.

Abstract
Brucellosis is one of the most common zoonosis worldwide. It is still endemic in many regions of the world. A 6-year-old female was admitted to the emergency department (ED) due to a sudden change in consciousness, urinary incontinence, vomiting, and difficulty in walking. Neurological examination demonstrated abducens nerve paralysis, mild-to-moderate motor deficit in hemiparesis in the left arm. Brain magnetic resonance imaging showed a hemorrhagic focus at the right frontal lobe and thrombosis in the superior sagittal sinus of the brain. The diagnosis of neurobrucellosis was confirmed by identifying Brucella spp. in the blood culture on the day 6 of pediatric intensive care unit admission; thus, trimethoprim-sulfamethoxazole and rifampicin, and ceftriaxone were promptly initiated. Despite neuroprotective management and acetazolamide, the patient's neurological problems and high intracranial pressure (ICP) persisted. An external ventricular drainage tube and a Codman ICP monitor were placed to be on the consent vigilance of the patient's neurological condition. The patient's ICP continued to increase despite the current treatment regimen; therefore, a decompressive bitemporal craniectomy was performed. The ICP level of the patient returned to its normal range immediately after the craniectomy. The patient did not have any notable neurologic sequelae at the first-year follow-up. Neurobrucellosis is a rare complication of systemic brucellosis and may present as meningitis, encephalitis, myelitis, radiculitis, and/or neuritis. Herein, we describe a six-year-old girl with brucellosis complicated with cerebral vein thrombosis. This case illustrates the need for close monitoring of patients with unexplained neurological signs or symptoms for brucellosis in endemic areas.
