Rapid diagnostic testing method to detect ROB β-lactamase gene in Neisseria meningitidis.

bla is the only widely found β-lactamase in Neisseria meningitidis, and its presence is on the rise. To enhance our bacterial meningitis testing procedure, we clinically validated a real-time PCR assay to rapidly detect the bla gene and predict drug resistance in Neisseria meningitidis. A screen of 101 clinical isolates and 37 clinical specimens of blood and cerebrospinal fluid received between January 2018 and June 2024 found 8 isolates and 2 cerebrospinal fluid specimens that were positive for bla.

Implementation of a high-throughput whole genome sequencing approach with the goal of maximizing efficiency and cost effectiveness to improve public health.

Unlabelled: This manuscript describes the development of a streamlined, cost-effective laboratory workflow to meet the demands of increased whole genome sequence (WGS) capacity while achieving mandated quality metrics. From 2020 to 2021, the Wadsworth Center Bacteriology Laboratory (WCBL) used a streamlined workflow to sequence 5,743 genomes that contributed sequence data to nine different projects. The combined use of the QIAcube HT, Illumina DNA Prep using quarter volume reactions, and the NextSeq allowed the WCBL to process all samples that required WGS while also achieving a median turn-around time of 7 days (range 4 to 10 days) and meeting minimum sequence quality requirements.

Comparative analysis of multiplexed PCR and short- and long-read whole genome sequencing to investigate a large Klebsiella pneumoniae outbreak in New York State.

In 2017, the New York State Department of Health investigated a large Klebsiella pneumoniae outbreak in a health care facility. A retrospective analysis was conducted to compare the use of multiple molecular typing methods for characterizing the outbreak. Forty-four isolates were characterized using the rapid real-time PCR OpGen Acuitas® AMR Gene Panel.

Laboratory diagnosis of bacterial meningitis by direct detection, serotyping and Next Generation Sequencing: How 10 years of testing in New York State has evolved to improve laboratory diagnosis and public health.

Since 2005, the Wadsworth Center (WC) has provided molecular testing on cerebrospinal fluid (CSF) and whole blood specimens in close collaboration with epidemiologists in New York State and New York City. In this study, we analyzed 10 years of data to demonstrate the significant value of utilizing molecular methods to assess patient specimens for etiologic agents of bacterial meningitis. A comprehensive molecular testing algorithm to detect and serotype/serogroup bacterial agents known to cause bacterial meningitis (Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae and Streptococcus agalactiae) has evolved, and retrospective specimen testing has been essential for each improvement.

Legionnaires' Disease Outbreaks and Cooling Towers, New York City, New York, USA.

The incidence of Legionnaires' disease in the United States has been increasing since 2000. Outbreaks and clusters are associated with decorative, recreational, domestic, and industrial water systems, with the largest outbreaks being caused by cooling towers. Since 2006, 6 community-associated Legionnaires' disease outbreaks have occurred in New York City, resulting in 213 cases and 18 deaths.
