Microbiology Time – November 2023

Microbiology Time

October was a fruitful month! Read here the best three papers we selected:

  • The first study conducted in the US compared the performance of Colibrí™ with standard manual spotting for identifying bacteria in colonies grown from over 400 different samples, including urine, wound, respiratory, and positive blood cultures. The results showed that the two methods agreed 99.54% of the time, indicating that the use of Colibrí™ can help save time for technologists and ensure complete traceability from plating to organism identification.
  • The vaginal microbiome plays a crucial role in maintaining reproductive and overall women’s health. In this paper, Sara Leeber and her colleagues analyzed the self-collected vaginal microbiome of 3,345 Belgian women performing 16S amplicon sequencing and conducting questionnaires. The researchers found that the microbiome composition was strongly associated with age, childbirth, and menstrual cycle, and Lactobacillus species were dominant in 78% of the vaginal samples. Moreover, a network correlation analysis revealed specific bacterial taxa that were linked to certain conditions such as estrogen levels, contraceptive use, menopause, and breastfeeding. This study provides a detailed map of the vaginal microbiome associated with various health, lifestyle, and dietary factors, which will help with follow-up clinical and mechanistic research.
  • In the last years, full laboratory automation has transformed the field of clinical microbiology; today, deep learning architectures are fundamentally changing how computers can assist with challenging visual interpretation tasks in various domains. Here, the paper by Signoroni and colleagues introduces a system able to tackle a core task in clinical microbiology, the interpretation of diagnostic bacterial culture plates, including presumptive pathogen identification. The researchers achieved this by decomposing the problem into a hierarchy of complex subtasks and addressing them with a multi-network architecture called DeepColony. By working with a large stream of clinical data and a complete set of 32 pathogens, the suggested system effectively aided plate interpretation with a surprising level of accuracy in the extensive and rigorous framework of urinary tract infections. In conclusion, thanks to the rich species-related information generated, DeepColony can be used to develop trustworthy clinical decision support services in laboratory automation ecosystems. Surprise: Deepcolony is at the base of what PhenoMATRIX currently is!

Microbiology Time – October 2023

Microbiology Time

Here are the three papers we selected as the best ones in the last month:

  • Getting infected by Tuberculosis is a concrete risk for healthcare professionals working with TB patients, collecting and handling sputum samples for TB diagnosis. This study evaluates the risk perceptions of an alternative, less dangerous method to diagnose TB, tongue swabbing, implemented during the COVID-19 pandemic. Eighteen South African Healthcare professionals with experience using tongue swabbing at the South African Tuberculosis Vaccine Initiative were interviewed and assessed by their attitude toward provider-collected and supervised self-collected tongue swabbing. Facilitators and barriers to the use of tongue swabbing were also evaluated. Perception, barriers, and motivators of the use of tongue swabbing varied by use case, highlighting specific educational resources to enhance the safety of and adherence to the self-collection method.
  • HPV -DNA testing with self-collected samples showed extreme diagnostic accuracy and reliability. Nevertheless, to implement self-sampling in cervical screening programs, the standardization of the pre-analytical phase and the understanding of the acceptability of women are necessary in every country. In this second study, Illari Sechi and colleagues assessed the stability of self-collected vaginal samples, and the acceptability of self-collection in almost 200 women. Most of the women found it easy to use self-collection devices, and approximately half of the enrolled women declared preferring self-sampling to clinician-collected methods. This, paired with the high reliability and accuracy of HPV-DNA tests on self-collected samples, supports the adoption of self-collection in screening programs, even though HPV tests on self-samples must be standardized and optimized, and educational campaigns are needed to adequately inform and increase responsiveness in a target population.
  • Covid-19 is mainly a respiratory syndrome that can affect multiple organ systems with various symptoms. Deficits in smell and taste are some of the most common COVID-19 symptoms, which may last for months after the infection and which mechanisms are not fully elucidated. To identify the determinants of olfactory symptom persistence, the Italian research group obtained olfactory mucosa from 21 subjects and grouped them by the severity/persistence of olfactory symptoms. By analyzing cells with transcriptome analyses, Lupi and colleagues discovered that the overall gene expression and micro-RNA expression profile are altered for a long time after infection. Patients with persistent olfactory deficits displayed increased expression levels of genes related to inflammation and zinc homeostasis, suggesting an association of this metal with the olfactory deficit.

UriSponge® is back in business!

UriSponge®

UriSponge® is our beloved device for urine specimen collection, transport, and preservation from the sampling site to the testing laboratory.   

The good old UriSponge® 

Copan developed this innovative device with a sponge that rapidly, easily, and safely adsorbs the correct amount of urine, making the sample collection step and subsequential processing in the lab much simpler. This unique design avoids cumbersome urine transfer to other tubes and has helped hundreds of laboratories in the procedures for the cultivation of uropathogenic bacteria and yeasts. UriSponge® compact and leak-proof tube ensured a cost-effective shipment of samples to the laboratory, where they can either be loaded directly on the WASP® for automated streaking or manually centrifuged for manual processing of urine with standard culture procedures. All this in full compliance with M40-A2 and IVDR standards

 

But we could do better. 

Today, the time has come to unveil a new, updated version of UriSponge®, which still offers the same convenience and easiness of use but with an advanced preservative formula free of boric acid. The reasons behind this choice are obvious: no dangerous chemicals for humans or the environment mean increased sustainability; no handling and logistic issues related to boric acid mean no availability disruptions and faster delivery times. Additionally, the new UriSponge®’s formula outperforms other devices based on boric acid, as urine collected in UriSponge® can be stored at room temperature for up to 48 hours controlling the risk of overgrowth or overkill during transport. 

UriSponge® is immediately available to be ordered*. Contact us for more info. 

*Currently available for countries that require CE marking and apply IVD regulation.
