Patients without human immunodeficiency virus (HIV) are increasingly recognized as being at risk for cryptococcosis. Knowledge of characteristics cryptococcosis in these patients remains incomplete.We conducted a retrospective study 46 Australian and New Zealand hospitals to compare its frequency with HIV describe HIV. between January 2015 December 2019 were included.Of 475 cryptococcosis, 90% (426 475) marked predominance both Cryptococcus neoformans (88.7%) gattii cases (94.3%). Most...
The resistance mechanisms of more than 2,000 aminoglycoside-resistant gram-negative aerobic bacteria were estimated by a method that assigned biochemical mechanism based on susceptibility to selected aminoglycosides. Strains from hospitals in Japan, Formosa, and Korea (the Far East) compared with strains Chile the United States. Of Chile, 90% had an aminoglycoside pattern indicative 3-N-acetyltransferase [AAC(3)-V] enzyme. East, 78% patterns suggesting presence AAC(6') enzymes. In contrast,...
In 2011 a novel methicillin resistance gene, mecC, was described in human and bovine Staphylococcus aureus isolates. mecC-positive S. is most commonly associated with livestock wildlife populations across Europe particularly prevalent hedgehogs, but only occasionally causes infections. this study we characterize investigate the origin of two isolates containing mecC genes from New Zealand. The were identified patients severe invasion infection as part bacteraemia study. Whole genome...
Staphylococcus argenteus (SARG) was discovered in 2009 as part of the aureus (SAUR) complex and has been documented from various locations worldwide. In this article we describe genomic features five strains SARG found Christchurch, New Zealand. Isolates were first detected 2019 using MALDI-ToF identification, their identities confirmed whole genome sequencing (WGS). Genomic features, including antimicrobial resistance markers virulence factors compared to other sequences NCBI GenBank. Four...

A negative sputum smear does not exclude substantial risk of infection from patients with pulmonary tuberculosis
In 2011, a novel methicillin resistance gene, mecC , was described in human and bovine Staphylococcus aureus isolates. mecC- positive S. is most commonly associated with livestock wildlife populations across Europe particularly prevalent hedgehogs, but only occasionally causes infections. this study, we characterize investigate the origin of two isolates containing genes from New Zealand. The were identified patients severe invasion infections as part an bacteraemia study. Whole-genome...
The objective of this study was to compare the performance an in-house CIM (iCIM) modification with and mCIM for detection carbapenemase production in 149 well characterised isolates (70 producers 79 non-carbapenemase producers). Isolates were tested using CIM, iCIM procedures. gold standard genotypic characterisation by PCR. For Acinetobacter baumannii, sensitivity low (10%) mCIM, 70% but 100% iCIM, a specificity all three. Enterobacterales, three tests Ambler class A B β-lactamases, while...
Abstract Xanthomonas axonopodis pv. vasculorum (Xav), the causative agent of sugarcane gumming disease, represents a significant threat to global production due its systemic and destructive nature. Despite economic implications, field-deployable, Xav-specific diagnostic tool has not been developed. This resulted in loop-mediated isothermal amplification (LAMP) assay targeting pelL gene, unique Xav strains, as rapid precise assay. The selection gene was informed by comprehensive silico...
Abstract Introduction The Serratia marcescens enzymes (SMEs) are chromosomally encoded Ambler Class A carbapenem-hydrolysing β-lactamases, which distinctively express resistance to carbapenems while remaining susceptible extended-spectrum cephalosporins. Global reports of SMEs infrequent. Here we describe the isolation an SME-2-producing S. from sputum a patient who was hospitalized at Christchurch Hospital, New Zealand. Methods An immunosuppressed asthmatic presented with shortness breath...
Staphylococcus aureus bacteraemia is associated with significant morbidity and mortality. There evidence that standardised care bundle implementation may improve the rates of appropriate investigations overall management. A S. was introduced at Christchurch Hospital, New Zealand in early 2014. We assessed impact intervention on management outcome bacteraemia.A cohort study cases conducted following introduction. Prospective enrolment post-intervention patients occurred from 1st January 2014...
We report a case of catheter-associated Elizabethkingia miricola bacteraemia in haemodialysis patient. The patient was 73-year-old home who presented with history recurrent falls and fevers. Blood cultures grew Gram-negative bacilli identified by MALDI-TOF MS (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry 6903 MSP Library) 16S rRNA gene sequencing as E. miricola. is an emerging human pathogen multidrug-resistant, making the choice antimicrobial therapy...
