San Diego University Researchers Believe Bacteriophages May Be the Future of Eradicating Multi-Drug Resistant Superbugs

Clinical laboratories and microbiologists may soon have new powerful tools for fighting antimicrobial resistant bacteria that saves lives

Superbugs—microbes that have developed multidrug resistance—continue to cause problems for clinical laboratories and hospital antibiotic stewardship programs around the world. Now, scientists at San Diego State University (SDSU) believe that bacteriophages (phages) could provide a solution for dealing with multi-drug resistant superbugs.

Phages are miniscule, tripod-looking viruses that are genetically programmed to locate, attack, and eradicate a specific kind of pathogen. These microscopic creatures have saved lives and are being touted as a potential solution to superbugs, which are strains of bacteria, viruses, parasites, and fungi that are resistant to most antibiotics and other treatments utilized to counteract infections.

“These multi-drug-resistant superbugs can cause chronic infections in individuals for months to years to sometimes decades,” Dwayne Roach, PhD, Assistant Professor of Bacteriophages, Infectious Disease, and Immunology at SDSU told CNN. “It’s ridiculous just how virulent some of these bacteria get over time.”

Labs across the country are conducting research on phages in eradicating superbugs. Roach’s lab is currently probing the body’s immune response to phages and developing purification techniques to prepare phage samples for intravenous use in patients.

“There are a lot of approaches right now that are happening in parallel,” said Dwayne Roach, PhD (above), Assistant Professor of Bacteriophages, Infectious Disease, and Immunology at San Diego State University (SDSU), in a CNN interview. “Do we engineer phages? Do we make a phage cocktail, and then how big is the cocktail? Is it two phages or 12 phages? Should phages be inhaled, applied topically, or injected intravenously? There’s a lot of work underway on exactly how to best do this.” Clinical laboratories that test for bacterial infections may play a key role in diagnosis and treatment involving bacteriophages.

Building Libraries of Phages

When certain a bacterial species or its genotypes needs to be annihilated, a collection of phages can be created to attack it via methods that enter and weaken the bacterial cell. The bacteria will attempt to counter the intrusion by employing evasive actions, such as shedding outer skins to eliminate the docking ports utilized by the phages. These maneuvers can cause the bacteria to lose their antibiotic resistance, making them vulnerable to destruction. 

Some research labs are developing libraries of phages, accumulating strains found in nature in prime breeding grounds for bacteria to locate the correct phage for a particular infection. Other labs, however, are speeding up the process by producing phages in the lab.

“Rather than just sourcing new phages from the environment, we have a bioreactor that in real time creates billions upon billions of phages,” Anthony Maresso, PhD, Associate Professor at Baylor College of Medicine in Houston told CNN. “Most of those phages won’t be active against the drug-resistant bacteria, but at some point, there will be a rare variant that has been trained, so to speak, to attack the resistant bacteria, and we’ll add that to our arsenal. It’s a next-generation approach on phage libraries.”

Maresso and his team published their findings in the journal Clinical Infectious Diseases titled, “A Retrospective, Observational Study of 12 Cases of Expanded-Access Customized Phage Therapy: Production, Characteristics, and Clinical Outcomes.”

For the Baylor study, 12 patients were treated with phages customized to each individual’s unique bacterial profile. The antibiotic-resistant bacteria were exterminated in five of the patients, while several others showed improvement.

Clinical trials are currently being executed to test the effectiveness of phages against a variety of chronic health conditions, including:

Using a phage cocktail could be used to treat a superbug outbreak in real time, while preventing a patient from a future infection of the same superbug. 

“The issue is that when patients have infections with these drug-resistant bacteria, they can still carry that organism in or on their bodies even after treatment,” Maroya Walters, PhD, epidemiologist at the federal Centers for Disease Control and Prevention (CDC) told CNN.

“They don’t show any signs or symptoms of illness, but they can get infections again, and they can also transmit the bacteria to other people,” she added.

More Studies are Needed

According to CDC data, more than 2.8 million antimicrobial-resistant (AMR) infections occur annually in the United States. More than 35,000 people in the country will die as a result of these infections.

In addition, AMR infections are a huge global threat, associated with nearly five million deaths worldwide in 2019. Resistant infections can be extremely difficult and sometimes impossible to treat.

“It’s estimated that by 2050, 10 million people per year—that’s one person every three seconds—is going to be dying from a superbug infection,” epidemiologist Steffanie Strathdee, PhD, Associate Dean of Global Health Services and co-director at the Center for Innovative Phage Applications and Therapeutics (IPATH) at the UC San Diego School of Medicine, told CNN.

The CDC’s 2019 report on bacteria and fungi antimicrobial resistant threats named five pathogens as urgent threats:

More research is needed before phages can be used clinically to treat superbugs. But if phages prove to be useful in fighting antibiotic-resistant bacteria, microbiologists and their clinical laboratories may soon have new tools to help protect patients from these deadly pathogens.

Understanding Gen Z’s Approach to Healthcare Helps Clinical Laboratories Learn How to Better Meet Their Needs

Healthcare providers of all types will benefit from acknowledging Gen Z’s preference for digital interactions, self-testing, and over-the-counter medications

Each generation has its own unique connection to how it manages its health, and the latest studies into the healthcare habits of Generation Z (aka, Gen Z or Zoomers) are providing valuable insight that savvy clinical laboratory managers and pathologists—in fact all healthcare providers—can use to better serve their Gen Z patients.

According to McKinsey and Company, Gen Z’s “identity has been shaped by the digital age, climate anxiety, a shifting financial landscape, and COVID-19.” And Pew Research states that Zoomers “are also digital natives who have little or no memory of the world as it existed before smartphones.”

As the largest demographic, “Gen Z stands 2.6 billion members strong. … Globally, they hold purchasing power of more than $500 billion and mobile buying power of $143 billion,” wrote Stacy Rapacon, Managing Editor at Senior Executive Media, in an article she penned for HP’s The Garage.

Meeting Gen Zers’ healthcare needs on their terms would seem to be a judicious choice.

“Gen-Z’s buying power may exceed $3 trillion,” wrote Bernhard Schroeder (above), a clinical lecturer on integrated/online marketing at San Diego State University, in Forbes. “Their spending ability exceeds the gross domestic product of all but about 25 of the world’s countries.” Thus, it behooves healthcare leaders, including clinical laboratory managers and pathologists, to consider how best to approach treating Gen Z patients.

Gen Z Leads in Digital Healthcare Use, Self-testing, OTC Drugs

“Gen Z engages in every type of digital healthcare activity more than other generations,” a recent study by PYMNTS noted. A total of 2,735 consumers were surveyed, and though all reported using digital healthcare to some degree, Gen Z stood out.

Patient portal access was the highest digital method accessed by Zoomers (62%), followed by telemedicine appointment usage (55%), the PYMNTS report found.

Knowing the direction Gen Z is trending may lead clinical laboratory leaders to expect self-testing to be on the rise, and that hunch would be correct. “There are two converging trends; the rise of women’s health technology and increased use of at-home sample collection for diagnosis tests,” Clinical Lab Products reported.

“Ongoing innovation in these areas could significantly improve the accessibility of women’s health testing. It will also have repercussions for labs, potentially changing the way samples are received and processed, and the way results are distributed. The quantity and quality of samples may be impacted, too. It’s important for labs to be aware of likely developments so they can prepare, and potentially collaborate with the health technology companies driving change,” CLP noted.

Another area feeling the impact of Gen Z’s healthcare spending is the over-the-counter (OTC) drug market.

“Since the pandemic began, more Americans are paying closer attention to their symptoms and looking for easily accessible information about over-the-counter medications, especially for allergies, coughs, and headaches,” said Kim Castro, Editor and Chief Content Officer for US News and World Report, in a press release.

Zoomers Want Healthcare on Their Own Terms

Gen Z grew up with the internet, Amazon, Netflix, Google, and social media since birth.

“The ‘norm’ they experienced as children was a world that operated at speed, scale, and scope. They developed an early facility with powerful digital tools that allowed them to be self-reliant as well as collaborative,” anthropologist Roberta Katz, PhD, a senior research scholar at Stanford’s Center for Advanced Study in the Behavioral Sciences (CASBS) told Stanford News.

As digital natives, Gen Z can be more science and data driven and yet still expect to find health advice on YouTube or TikTok. According to an article published by Harvard Pilgrim Healthcare, “Gen Z is the first generation to grow up surrounded by digital devices, and they expect their health benefits to be digital, too. From choosing a benefits package to finding a provider, Gen Z wants to take care of their health on their own terms. And that may just include video chatting with a doctor from the back of an Uber.”

In its 2022 US Digital Health Survey, research firm Insider Intelligence found that “Half of Gen Z adults turn to social media platforms for health-related purposes, either all the time or often.”

“Gen-Z will make up 31% of the world’s population by 2021 and they have deeply formed perceptions and beliefs … This has led to an amazing change in the way Gen-Z is disrupting several industries simultaneously,” wrote Bernhard Schroeder (above), a clinical lecturer on integrated/online marketing at San Diego State University, in Forbes.

What Can Clinical Laboratories Learn from These Findings

Gen Z seeks accuracy and trustworthy information. “Gen-Zers’ natural penchant for skepticism and frugality—coupled with low levels of confidence in the US healthcare system—makes them less likely to trust providers, more likely to research prices before seeking care, and more apt to worry that their health insurance won’t cover their treatment,” Insider Intelligence noted.

According to Contract Pharma, “Gen Z is concerned with holistic health and self-care, rather than a one size fits all pharmaceutical approach. They share a hesitancy for traditional healthcare models but with very interesting differences. By understanding these differences, the consumer healthcare industry can focus on agile and distinctive brands to harness Gen Z’s tremendous purchasing power.”

Savvy clinical laboratory leaders can better serve their Gen-Z client physicians and patients by better understanding why Zoomers are more inclined to order their own lab tests (without a physician), collect their own specimens to send into labs, and/or collect their own specimens to do home testing (think COVID-19 self-test kits). Zoomers may need an entirely new business model from their healthcare providers, including clinical laboratories.

Hawaii Poised to Become the First State to Adopt a State Microbe, Possibly Elevating Awareness of Clinical and Microbiology Laboratories

Distinction of “official state microbe” could raise awareness of microbiology among students

Not many pathologists or clinical laboratory managers know that a race is on to become the first state to adopt a specific bacterium as the official state microbe. Wisconsin tried and failed. Now Hawaii is in the race for the distinction.

Just weeks ago, on March 6, 2012, Hawaii’s House of Representatives passed House Bill HB2079. This is a bill that would recognize the bacterium Nesiotobacter exalbescens as the state’s official microbe. This puts Hawaii in the running to be first to officially recognize a state microbe.
