Long COVID (LC), manifests in 10-30% of non-hospitalized individuals post-SARS-CoV-2 infection leading to significant morbidity. The predictive role of gut microbiome composition during acute infection in the development of LC is not well understood, partly due to the heterogeneous nature of disease. We conducted a longitudinal study of 799 outpatients tested for SARS-CoV-2 (380 positive, 419 negative) and found that individuals who later developed LC harbored distinct gut microbiome compositions during acute infection, compared with both SARS-CoV-2-positive individuals who did not develop LC and negative controls with similar symptomatology.

In this report, we describe a case of septic arthritis caused by the newly described (formerly complex). The patient's only significant exposure was home gardening. To our knowledge, this represents the first documented case of infection in the United States and first septic arthritis.

Objectives: To describe our experience with men admitted to a tertiary care hospital with genital injury.

Methods: Adult men with injuries of the genitals, admitted to our institution between January 2013 and June 2018, were identified from our institutional trauma registry. Patient charts were queried to extract mechanism, management, follow-up, and complications.

Nucleoside diphosphate kinases (NDKs) are implicated in a wide variety of cellular functions owing to their enzymatic conversion of NDP to NTP. NDK from Borrelia burgdorferi (BbNDK) was selected for functional and structural analysis to determine whether its activity is required for infection and to assess its potential for therapeutic inhibition. The Seattle Structural Genomics Center for Infectious Diseases (SSGCID) expressed recombinant BbNDK protein.

Background: A large gap for the support of point-of-care testing is the availability of reagents to support quality control (QC) of diagnostic assays along the supply chain from the manufacturer to the end user. While reagents and systems exist to support QC of laboratory screening tests for glucose-6-phosphate dehydrogenase (G6PD) deficiency, they are not configured appropriately to support point-of-care testing. The feasibility of using lyophilized recombinant human G6PD as a QC reagent in novel point-of-care tests for G6PD deficiency is demonstrated.

Article Synopsis
  • Researchers identified prolyl-tRNA synthetase (ProRS) in the malaria-causing parasite Plasmodium falciparum (Pf) as a promising drug target, but selective inhibitors for this target were previously unreported.
  • By screening around 40,000 compounds, the study discovered two new allosteric inhibitors that specifically target PfProRS with over 100 times more selectivity than the human version (HsProRS).
  • The findings, supported by X-ray crystallography, pave the way for further medicinal chemistry efforts to optimize these inhibitors for potential malaria treatments without the toxicity associated with existing drugs.
