It’s been almost 10 years since I left the laboratory world behind…
… it’s funny how the grossly putrid scents of stool samples, bacterial growth, and my co-workers’ poor hygiene (just kidding!… no, really!!) that repelled me in my early lab days are now a strangely missed part of my everyday world… go figure!
Today I’ve put together a fictional, yet realistic amalgamated storyline of a couple of cases I encountered in my years in the Microbiology “trenches”… scary, almost helpless episodes where a life teetered on the edge from a typical, “average” kind of infection… but not this time…
The Routine Request
The sterile hum of lab equipment and studious calmness, along with the malodorous but “normal” smell of agar and bacterial scents filled the air as Diane sifted through the daily microbiology requests.
Emily Turner’s name stood out in bold red, marked “URGENT.”
As a microbiology technologist at St. Mary’s General Hospital, she was accustomed to the urgency of swift diagnoses, but little did she know that the seemingly innocuous small cut below Emily’s knee would catapult her into a race against time.
Emily, a vibrant 32-year-old woman, had sought medical attention for what appeared to be an unexceptional, but bothersome injury.
Just a small cut from bumping around the edge of a tabletop, barely noticeable, had become the entry point for a lurking menace – Staphylococcus aureus. This bacterium, an occasional inhabitant of the skin and mucous membranes, had found an opportunity to turn a routine scratch into a life-threatening situation.
The culture swab arrived in the lab – encased in a long clear container half-filled with a non-nutritive gel – just like any other. Diane carefully prepared the culture plates and smears on glass slides, and began the routine tests.
Everything seemed ordinary until her eyes caught an unexpected menace under the microscope, using a standard test called a gram stain – large clusters of purple grape-like organisms typical of a Staphylococcus species, accompanied by a plethora of pinkish white blood cells (yes, pus!), a strong indicator of real infection.
.
The bacteria had found its way into the small cut below Emily’s knee, and after contacting the patient’s physician, it became clear to Diane that the consequences were dire – gangrene had already set in, spreading rapidly.
The microscopic world revealed a battlefield of bacterial warfare, and Emily’s leg was the battleground. The trauma of that seemingly insignificant cut had triggered a chain reaction, inviting the ruthless Staphylococcus aureus to invade deeper into her tissues.
The bacterium had turned into a formidable adversary, transforming a minor injury into a medical emergency.
As Diane delved deeper into the research, seeking answers to the unfolding medical drama, she uncovered the insidious nature of necrotizing fasciitis.
This rare and severe infection occurs when bacteria infiltrate the fascial layers (fascia are like the thin, fibrous film you peel off the back of pork ribs before cooking) beneath the skin, rapidly causing tissue death. A highly resistant Methicillin-resistant Staphylococcus aureus (MRSA) was orchestrating a devastating attack, leaving destruction in its wake.
Necrotizing fasciitis, aptly referred to as “flesh-eating disease,” thrives on the breakdown of soft tissue.

The infection spreads relentlessly and rapidly, navigating through the body’s intricate network of fascial planes, leaving behind a trail of devastation.
In Emily’s case, the trauma of that initial small cut had set the stage for a medical emergency that would test the limits of modern medicine.
The urgency of the situation became palpable as the Microbiology tech studied the laboratory results, both the culture tests and other chemistry assays that indicated a rising level of inflammation in Emily’s body. Clearly, there was a spiralling danger that was heading towards a cliff.
Gangrene, a consequence of the unchecked bacterial invasion where the blood supply to the affected tissue is compromised, had silently set in, claiming territory within Emily’s leg. The tissue, once healthy and vibrant, now faced a relentless assault, turning black and lifeless. Amputation of the leg was a real possibility.
The small cut below Emily’s knee, initially dismissed as trivial, had become the epicentre of a battle against time. Gangrene had set the stage for a cascade of events that threatened not only Emily’s leg but her very existence.
As the microscopic battle within Emily’s leg unfolded, it wasn’t just a clash between bacteria and antibiotics.
It evolved into a war that triggered a cytokine storm (IL-2, IL-6, TNF (alpha)), an internal inflammatory response that further threatened her life. The Staphylococcus aureus had not only invaded her tissues but had incited an immune system overreaction, releasing a torrent of cytokines that led to widespread inflammation.
This cytokine storm, a double-edged sword in the fight against infection, had become an unwelcome complication.
Instead of aiding in the eradication of the bacteria, as is the usual case, the exaggerated immune response was causing collateral damage, intensifying the urgency of medical actions.
Emily’s body, caught in the crossfire of the microscopic battlefield, faced not only the bacterial invasion but also the turmoil of its own immune system which could send her into septic shock and multi-organ failure.
Every test result felt like a desperate call for action.
Diane had quickly uncovered the identity of the merciless bacteria – a highly resistant strain of Staphylococcus aureus. She also carried out tests to determine the best antibiotics with a fighting chance to take out the intruder.
Armed with this data, including the short list of antibiotics that would hopefully be effective, she communicated with Dr. Thompson, the attending physician determined to prevent the bacteria from claiming Emily’s leg and life.
The drama unfolded like a medical thriller, with the urgency reaching its peak.
Emily underwent tissue debridement, a surgical procedure to remove the infected and necrotic tissue, accompanied by the heavy use of targeted antibiotics and supportive therapy.
Against all odds, she emerged victorious.
The once-threatening Staphylococcus aureus was conquered, despite statistics showing that upwards of 30% of patients may succumb to the frightening scourge of necrotizing fasciitis.
The lab report, often a routine task, transformed into a saga of determination, skill, and triumph over the bacterial foe. Maybe even a touch of luck.
Emily’s leg, and her life, were saved by the collaborative efforts of physicians, lab techs, and nursing staff in a furious battle.
Gaining insights into necrotizing fasciitis and the cytokine storm proved pivotal in confronting the microscopic opponent.
The trauma of a small cut, magnified by a tenacious and resilient bacterium, had unmasked the fragility of the human body as well as the shortcomings of medical knowledge that still has so much to learn.
