Development and Validation of a Novel Anaerobic Carbapenem Inactivation Method (Ana-CIM) for the Detection of Carbapenemase Production in Bacteroides fragilis.

Antibiotic resistance, particularly to carbapenems, is of increasing concern in Bacteroides fragilis. Carbapenem resistance in B. fragilis is most often mediated by the activation of chromosomally encoded metallo-β-lactamase by the presence of an upstream insertion sequence (IS).

Clinical utility of anaerobic culture of cerebrospinal fluid.

Anaerobic meningitis is a rare serious clinical condition which mainly affects vulnerable populations and patients with predisposing factors such as head trauma, prior neurosurgical procedures or implantable medical devices such as ventriculoperitoneal shunts or ventricular drains. In this study we retrieved data from aerobic and anaerobic cultures of cerebrospinal (CSF) or ventricular fluid ordered over a 5 year period at our institution. A total of 8868 aerobic and 594 anaerobic cultures were performed from 2013 to 2017.

Clostridioides difficile Whole-genome Sequencing Differentiates Relapse With the Same Strain From Reinfection With a New Strain.

Background: Current approaches in tracking Clostridioides difficile infection (CDI) and individualizing patient management are incompletely defined.

Methods: We recruited 468 subjects with CDI at Mayo Clinic Rochester between May and December 2016 and performed whole-genome sequencing (WGS) on C. difficile isolates from 397.

Routine use of MALDI-TOF MS for anaerobic bacterial identification in clinical microbiology.

In 2013, we adopted MALDI-TOF MS using the Bruker Biotyper system for identification of anaerobic bacteria into our routine clinical practice. Here, we describe our experience with the use of MALDI-TOF MS for anaerobic bacterial identification, highlighting its value in replacing the more costly and time-consuming 16S ribosomal RNA gene PCR plus sequencing-based approach as the primary method of anaerobic bacterial identification. We also describe our more recent experience with the use of early/rapid MALDI-TOF MS for identification of anaerobic bacteria performed on short incubation (4-6 h) plated aerobic media from anaerobic blood culture bottles positive for Gram-negative bacilli.

Laboratory Workflow Analysis of Culture of Periprosthetic Tissues in Blood Culture Bottles.

Culture of periprosthetic tissue specimens in blood culture bottles is more sensitive than conventional techniques, but the impact on laboratory workflow has yet to be addressed. Herein, we examined the impact of culture of periprosthetic tissues in blood culture bottles on laboratory workflow and cost. The workflow was process mapped, decision tree models were constructed using probabilities of positive and negative cultures drawn from our published study (T.

Blame it on patriarchy: more sexist attitudes are associated with stronger consideration of cosmetic surgery for oneself and one's partner.

In the present work, we examined associations between oppressive, sexist beliefs and consideration of cosmetic surgery for oneself and also endorsement of cosmetic surgery for one's romantic partner. A total of 554 German-speaking volunteers from the community, mainly in Austria, completed measures of consideration of cosmetic surgery and three measures of sexist attitudes, while a subset of participants in romantic relationships completed a measure of endorsement of cosmetic surgery for their partners along with the measures of sexism. Preliminary analyses showed that women and single respondents were more likely to consider having cosmetic surgery than men and committed respondents, respectively.
