Reports of invasive disease due to Streptococcus pneumoniae have declined since the introduction of pneumococcal conjugate vaccines (PCV7 and PCV13). The incidence of invasive diseases due to S. pneumoniae that are not addressed by the vaccines, however, has increased in children and adults, creating a global public health problem. Previously, we established the loop-mediated isothermal amplification (LAMP) method for a PCV13 serotype-specific assay. In the current study, we developed a rapid, simple, and cost-effective assay to detect serotypes in the 23-valent pneumococcal polysaccharide vaccine (PPSV23) using the LAMP method. In this study, LAMP primer sets for serotypes 2, 8, 9N, …

Development Of A Novel Loop-Mediated Isothermal Amplification Method To Detect Guiana Extended-Spectrum (Ges) Β-Lactamase Genes In Pseudomonas Aeruginosa, Chika Takano, Mitsuko Seki, Dong Wook Kim, Humphrey Gardner, Robert E. Mclaughlin, Paul E. Kilgore, Kazunari Kumasaka, Satoshi Hayakawa

Infections caused by multidrug-resistant Pseudomonas aeruginosa in hospitalized patients are often fatal, and nosocomial infections caused by Guiana extended-spectrum (GES) β-lactamase-producing strains are of growing concern. Several genotypes of the GES β-lactamase gene (bla_GES) include a single missense mutation, a change from G to A at nucleotide position 493 (G_493A) that changes glycine to serine; the mutant enzyme exhibits carbapenemase activity. Rapid and reliable identification of drug-resistance is important in clinical settings; however, culture methods remain the gold standard. Conventional and real-time PCR cannot identify carbapenemase-producing genotypes, and direct DNA sequencing is essential. We established …

Epidemiology Of Diabetic Foot Infection In The Metro-Detroit Area With A Focus On Independent Predictors For Pathogens Resistant To Recommended Empiric Antimicrobial Therapy, Oryan Henig, Jason M.

Background. The polymicrobial nature of diabetic foot infection (DFI) and the emergence of antimicrobial resistance have complicated DFI treatment. Current treatment guidelines for deep DFI recommend coverage of methicillin-resistant Staphylococcus aureus (MRSA) and susceptible Enterobacteriaceae. This study aimed to describe the epidemiology of DFI and to identify predictors for DFI associated with multidrug-resistant organisms (MDROs) and pathogens resistant to recommended treatment (PRRT).

Methods. Adult patients admitted to Detroit Medical Center from January 2012 to December 2015 with DFI and positive cultures were included. Demographics, comorbidities, microbiological history, sepsis severity, and antimicrobial use within 3 months before DFI were obtained …

Loop-Mediated Isothermal Amplification Methods For Diagnosis Of Bacterial Meningitis, Mitsuko Seki, Paul E. Kilgore, Eun Jin Kim, Makoto Ohnishi, Satoshi Hayakawa, Dong Wook Kim

Department of Pharmacy Practice

The rapid, accurate, and efficient identification of an infectious disease is critical to ensure timely clinical treatment and prevention in public health settings. In 2015, meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis was responsible for 379,200 (range: 322,700–444,700) deaths. Clinical features alone cannot determine whether bacterial meningitis is present; an analysis of cerebrospinal fluid (CSF) is essential. Loop-mediated isothermal amplification (LAMP) is a nucleic acid amplification method offering an alternative to polymerase chain reaction (PCR). LAMP-based assays for detection of three leading bacteria in CSF for diagnosis of meningitis have been established. The typing assays …

Molecular Serotype-Specific Identification Of Streptococcus Pneumoniae Using Loop-Mediated Isothermal Amplification, Chika Takano, Mitsuko Seki, Dong Wook Kim, Paul E. Kilgore, Kazumasa Fuwa, Koji Takahashi, Toshiaki Inazaki, Satoshi Hayakawa

Over the past four decades, the incidence of meningitis caused by Haemophilus influenzae in children has decreased due to widespread vaccination against H. influenzae type b (Hib). The incidence of invasive diseases due to H. influenzae types not included in the vaccines, however, has increased. At present, there are a limited number of diagnostics available to detect non-type b H. influenzae. To address this issue, we developed a rapid, simple, and cost-effective method for detecting serotypes of H. influenzae. We designed LAMP primer sets based on published sequences for H. influenzae capsular types a, c, d, e, and …

A Novel Loop-Mediated Isothermal Amplification Assay For Serogroup Identification Of Neisseria Meningitidis In Cerebrospinal Fluid, Dokyung Lee, Eun Jin Kim, Paul E. Kilgore, Hideyuki Takahashi, Jun Tomono, Shigehiko Miyamoto, Daisuke Omagari, Dong Wook Kim, Mitsuko Seki

We have developed a novel Neisseria meningitidis serogroup-specific loop-mediated isothermal amplification (LAMP) assay for six of the most common meningococcal serogroups (A, B, C, W, X, and Y). The assay was evaluated using a set of 31 meningococcal LAMP assay positive cerebrospinal fluid (CSF) specimens from 1574 children with suspected meningitis identified in prospective surveillance between 1998 and 2002 in Vietnam, China, and Korea. Primer specificity was validated using 15 N. meningitidis strains (including serogroups A, B, C, E, W, X, Y, and Z) and 19 non-N. meningitidis species. The N. meningitidis serogroup LAMP detected down to ten copies …
