Antibiotic resistance is frequently described as one of the most serious public health threats of our time — and for good reason. Yet for many residents of Southwest Florida, it remains an abstract concept rather than a concrete, daily concern. The reality is that antibiotic resistance in Southwest Florida is not a distant or hypothetical problem. It is here, it is growing, and it affects real patients in Fort Myers and throughout Lee County every year.
At Florida Infectious Disease Care, our board-certified specialists are at the front line of diagnosing and treating drug-resistant infections. Understanding what antibiotic resistance is, how it develops, and what you can do about it is not just good medical knowledge — it is a community responsibility.
What Is Antibiotic Resistance?
Antibiotic resistance occurs when bacteria evolve mechanisms that allow them to survive exposure to antibiotics that would normally kill them or stop their growth. This is a natural evolutionary process, but human behavior — particularly the overuse and misuse of antibiotics — has dramatically accelerated it.
When an antibiotic is used, it kills most susceptible bacteria. However, if any resistant bacteria are present, they survive and reproduce. Over time and with repeated antibiotic exposure, resistant strains come to dominate, making standard treatments ineffective. As the WHO notes, antibiotic resistance is now causing at least 1.27 million deaths globally each year — a number expected to rise dramatically if current trends continue.
How Does Antibiotic Resistance Develop?
Overuse in Human Medicine
When antibiotics are prescribed for viral infections — which they cannot treat — or when patients take antibiotics without a clear bacterial diagnosis, resistant bacteria are selected for without any therapeutic benefit. According to the CDC, at least 28% of antibiotics prescribed in the United States are unnecessary.
Incomplete Antibiotic Courses
When patients stop taking antibiotics early because they feel better — before the full course is completed — a portion of the bacterial population may survive. These surviving bacteria are the most resistant ones, and they multiply, creating a more resistant infection that is harder to treat on the second attempt.
Agricultural Antibiotic Use
Antibiotics are widely used in food animal production to promote growth and prevent disease in crowded farming conditions. This creates reservoir populations of resistant bacteria that can reach humans through the food supply or environmental exposure. Florida’s large agricultural sector makes this a locally relevant concern.
Global Travel
Resistant bacteria do not respect geographic borders. Travelers to regions with high antibiotic use and limited healthcare infrastructure can acquire resistant organisms and bring them back to Southwest Florida. Fort Myers — as a major travel hub — is not insulated from this global phenomenon.
The Most Concerning Resistant Organisms in Southwest Florida
MRSA
Methicillin-resistant Staphylococcus aureus remains the most commonly encountered drug-resistant organism in both community and healthcare settings across Florida. MRSA causes severe skin infections, bloodstream infections, and pneumonia that require specific antibiotics — vancomycin, daptomycin, or linezolid — that are not used in standard first-line prescribing.
Carbapenem-Resistant Organisms (CROs)
Carbapenem antibiotics are considered last-resort drugs for serious infections. The emergence of carbapenem-resistant Enterobacterales (CRE) — bacteria resistant even to these powerful agents — represents one of the most alarming developments in infectious disease. Treatment options for CRE infections are extremely limited and mortality rates are high.
Drug-Resistant Gonorrhea
Gonorrhea — already a common STI in Lee County — has progressively developed resistance to nearly every antibiotic class previously used to treat it. The CDC has declared drug-resistant gonorrhea an urgent public health threat. Currently, gonorrhea treatment requires a specific injectable antibiotic (ceftriaxone), and the pipeline for alternative treatments is thin.
C. difficile
Clostridioides difficile — commonly called C. diff — causes severe intestinal infection that typically develops after antibiotic use disrupts the normal gut bacteria. While not antibiotic-resistant itself, C. diff is a consequence of antibiotic overuse and is increasingly common in both healthcare and community settings in Florida.
What Can You Do as a Southwest Florida Resident?
Individual actions matter significantly in the fight against antibiotic resistance. Here is what you can do:
- Never take antibiotics without a prescription from a licensed provider
- Always complete the full prescribed antibiotic course, even if you feel better before finishing
- Never share antibiotics with another person or save leftover antibiotics for future use
- Ask your provider whether an antibiotic is truly necessary — and accept the answer if it is not
- Prevent infections through hand hygiene, vaccination, safe food handling, and safe sex practices
- If you develop an infection that is not responding to initial treatment, see a specialist rather than requesting a different antibiotic without testing
How Florida Infectious Disease Care Fights Antibiotic Resistance
Our specialists practice rigorous antimicrobial stewardship — a commitment to prescribing the most targeted, narrowest-spectrum antibiotic for the shortest effective duration, guided by culture and sensitivity results rather than assumption. We never prescribe antibiotics for viral illnesses and we use advanced diagnostic testing to identify resistant organisms quickly and precisely.
For patients with resistant infections, our general infectious disease team has access to the full range of specialized antibiotics and the expertise to use them correctly. We also offer comprehensive follow-up testing to confirm that treatment has been successful and resistance has not re-emerged.
Frequently Asked Questions
Q: How do I know if I have an antibiotic-resistant infection?
The clearest sign is an infection that fails to improve — or worsens — after a standard course of antibiotics. Cultures and sensitivity testing ordered by an infectious disease specialist can identify the specific organism and determine which antibiotics it remains sensitive to. This testing is essential for guiding appropriate treatment.
Q: Can antibiotic-resistant bacteria spread from person to person?
Yes. Resistant bacteria spread the same ways that non-resistant bacteria do — through direct contact, contaminated surfaces, droplets, and in some cases, through the food supply or environment. Good hand hygiene, wound care, and safe healthcare practices significantly reduce the risk of spread.
Q: If I have a resistant infection, does that mean I cannot be treated?
Not necessarily. While antibiotic-resistant infections are more challenging to treat, most have at least some remaining treatment options. The key is accurate identification of the organism and its resistance pattern, followed by targeted treatment with an antibiotic the organism remains sensitive to. This is exactly where infectious disease specialist expertise is critical.
Q: Is antibiotic resistance permanent?
Resistance can diminish in a population over time if antibiotic use is reduced — essentially allowing non-resistant strains to outcompete resistant ones. However, on an individual patient level, once you are infected with a resistant organism, it requires targeted antibiotic therapy to clear. Prevention and stewardship remain far more effective than trying to reverse resistance once it has developed.
