Tarnished gold—the “standard” urine culture: reassessing the characteristics of a criterion standard for detecting urinary microbes

Despite the high incidence of UTI diagnoses, the high cost of UTI treatment, and increasing concerns associated with antimicrobial resistance, the development of novel and more accurate UTI tests has not been considered a priority, in part due to the general perception that current UTI care is already sufficient. In this review, we discuss the importance of improving UTI diagnostic testing to improve treatment outcomes.

Introduction to Urobiome Metadata Standards

This video provides an overview of the National Microbiome Data Collaborative’s mission. Following this introduction, Dr. Lisa Karstens (Oregon Health & Science University) describes the data life cycle and what metadata is and how metadata standards can be adapted for urobiome research.

Forming Consensus To Advance Urobiome Research

Urobiome research has the potential to advance the understanding of a wide range of diseases, including lower urinary tract symptoms and kidney disease. Many scientific areas have benefited from early research method consensus to facilitate the greater, common good. This consensus document, developed by a group of expert investigators currently engaged in urobiome research (UROBIOME 2020 conference participants), aims to promote standardization and advances in this field by the adoption of common core research practices.

Standardization of microbiome studies for urolithiasis: an international consensus agreement

Numerous metagenome-wide association studies (MWAS) for urolithiasis have been published, leading to the discovery of potential interactions between the microbiome and urolithiasis. However, questions remain about the reproducibility, applicability and physiological relevance of these data owing to discrepancies in experimental technique and a lack of standardization in the field.

The human urobiome

Little is known concerning the relationship between the urobiome and host genetics; so far, only a single paper has reported such a study. However, major efforts have gone into understanding the genomics of the urobiome itself, a process facilitated by the fact that many urobiome studies have used metaculturomic methods to detect and identify microbes. In this narrative review, we will introduce the urobiome with separate sections on the female and male urobiomes, discuss challenges specific to the urobiome, describe newly discovered associations between the urobiome and lower urinary tract symptoms, and highlight the one study that has attempted to relate host genetics and the urobiome.

“Urinary Tract Infection”—Requiem for a Heavyweight

Mindful decisions about antibiotic use will require a far better understanding of how pathogenicity arises within microbial communities. It is likely that public education and meaningful informed-consent discussions about antibiotic treatment of bacteriuria, emphasizing potential harms and uncertain benefits, would reduce overtreatment. Emphasizing the microbiome’s significance and using the term “urinary tract dysbiosis” instead of “UTI” might also help and might encourage mindful study of the relationships among host, aging, microbiome, disease, and antibiotic treatment.

The Kidney: A Filter for Bacteria I. The Presence of Bacteria in the Blood, Kidney, and Urine After Varying Intervals Following Intravenous Injection

The role of the kidney as an excretory organ for formed particles has been investigated by numerous observers, the experimentation of whose technic has varied greatly and whose conclusions have been diametrically opposed. In these studies, the particles more immediately concerned are bacteria coursing in the circulation.
