Microbiology – The revolution continues

Microbiology has proved to be an important aspect of diagnostics, and continues be so. The next decade should prove intriguing as we strive to further impact clinical decision making for infectious diseases by advances in clinical microbiology.

Clinical microbiology has possessed a marvelous past, an important present, and has a bright future. With the advent of new technologies as AI, rapid evolution of antimicrobial resistance, and discovery of new pathogens, microbiology remains an important pillar of diagnostics.

Revolutionary changes, such as polymerase chain reaction (PCR) to increase cost effectiveness and improve clinical outcomes, use of NGS and mNGS technologies due to their sensitivity to detect low-frequency variants, and comprehensive genomic coverage to replace traditional diagnostic techniques, growing demand for gene therapy, personalized medicine, and increase usage of rapid microbiological test kits are on the way.

To make a diagnosis and track the development of microbial illnesses, clinical microbiology uses standard techniques like Gram stain morphology, in vitro culture, antigen and antibody assays, and molecular infections. As seen during the Covid-19 pandemic, clinical microbiology has been crucial in the identification and characterization of pathogens for new infectious illnesses.

Recent advances in clinical microbiology. The traditional microbiological techniques have been considerably replaced by new instruments launched in the market. Due to the potential advantages of quick identification for patient care, antimicrobial stewardship, and healthcare costs, direct detection of microbes from patient specimens is a topic of increasing interest. Clearly, quick organism identification affects treatment.

Antimicrobial therapy optimization may lessen the pressures that lead to resistance selection. The identification of bacteria and other microorganisms in the clinical microbiology laboratory has recently seen widespread use of electrospray ionization (ESI)-MS, matrix aided laser desorption ionization-time of flight (MALDI-TOF) MS, and ion trap-based identification technologies. The turn-around time will be impacted by the ability to identify organisms, using mass spectrometry technology straight from specimens as well as antibiotic susceptibility (MBT-ASTRA).

Automated specimen handlers can be used for slide preparation, manual plating of different types of specimens, and automated inoculation of liquid specimens. Platforms for organism identification and testing of an antibiotic’s susceptibility are provided by semi-automated technologies.

Usage of automation can be seen in the closed-system platforms and open-system platforms to carry out results in no time. The assays that have received regulatory approval are used for diagnostic purpose. Under the open-system, real-time and quantitative analysis are performed.

MALDI typing is a simple, cost-effective, and time-saving method in contrast to gold standard method, PFGE.

The microbiology market is rapidly growing with the development of new and innovative microbiological technologies like targeted polymerase chain reactions (PCRs) to increase the cost effectiveness, and improved clinical outcomes, growing popularity of broad range of molecular diagnosis to surge the sensitivity of diagnosis while promoting time effectiveness is significantly contributing to the market growth. Pyrosequencing techniques are being used to identify pathogens in blood culture bottles.

The development of patient-management methods is driving the expansion of the clinical microbiology sector. Additionally, the need for quick diagnostic methods is growing since infectious diseases, caused by viruses, bacteria, and parasites, among others, are becoming more common. This reduces the danger of lethal and hazardous side effects. The market expansion is anticipated to be aided by rising research and development (R&D) efforts to create novel antigen detection methods and sequencing tools that enable precise and affordable microbe identification.

Increased healthcare expenditure, rapid technological advances, increase in aging population, and the emergence of novel pathogenic infestation were the reasons observed for market growth in the past. Going forward, an increase in healthcare access and a rapid rise in various bacterial and viral epidemics drive the growth of the microbiology industry.

The other factors that are contributing to the growth of microbiology market are increasing funding of public and private investments in medical devices. Increasing investments indicate the rising confidence of various private and public players on microbiology diagnostic devices, thereby indicating a progressive increase and stimulating growth.

Factors that could hinder the growth of the microbiology diagnostic devices and equipment market include lack of skilled/trained microbiologists, regulatory challenges, political uncertainties, reduction in free trade, and low healthcare reimbursements.

Unfavorable regulatory scenarios are major restraints in the microbiology diagnosis devices market. In light of the rapidly advancing medical technologies and practices, laws and regulations cannot remain static. In the medical industry, patient’s safety and wellbeing must be guaranteed with the utmost care. The US is very strict in this aspect, section 510(k) of the Food, Drug, and Cosmetic Act states that every device manufacturer must register with FDA, and notify their intent to market a medical device at least 90 days in advance.

Outlook
There is a constant need for more rapid diagnoses, increased standardization of testing and greater adaptability to cope with new threats from emerging microbial pathogens. As early as 2004, Didier Raoult, the renowned French medical and clinical microbiologist, jointly with his team, proposed a bipolarization of future clinical microbiology services.

On the one hand, clinical microbiology practice will adhere to the overall trend in the life sciences toward big, centralized labs with the ability to analyze a lot of samples and perform a lot of different procedures. For bacterial culture, identification, and antibiotic susceptibility testing, complete automation has gradually been attained.

Future clinical microbiology practices will be polarized, utilizing both batched, high volumes of testing performed at a central laboratory and quick, random access tests performed at the point of care.

Clinical microbiology is a vibrant field today, despite its troubled background. The industry is prepared to embrace the future. Over the past ten years, the function of clinical microbiology laboratories has undergone significant modification. Research, diagnostic, and treatment techniques have undergone fast change as a result of the continuous technology revolution. Clinical microbiology practice will soon be able to assist physicians in implementing evidence-based therapies in real time, or considerably speed up the transition from empirical to evidence-based therapies.

Clinical microbiology seems set to improve its scientific standing while gaining a more distinct, profound, and ambitious medical landscape, social worth, and managerial relevance. New-age technologies and a variety of testing procedures, such as genome testing and mapping for genetic disorders, and multi-cancer early detection testing are prepping to join the market.

The next decade should prove intriguing as we strive to further impact decision making for infectious diseases by advances in clinical microbiology.
