 In this episode we dive into the resurgence of Mycoplasma pneumoniae—an atypical bacterial cause of community-acquired pneumonia that’s making waves in pediatric emergency medicine. We’ll cover its clinical presentation, epidemiology, diagnostic approach, and management, including why standard beta-lactam antibiotics won’t work. Plus, we’ll discuss whether M. pneumoniae even needs to be treated in the first place! Learning Objectives Describe the clinical presentation, epidemiology, and complications of Mycoplasma pneumoniae infections in pediatric patients, including its atypical manifestations.Differentiate Mycoplasma pneumoniae pneumonia from typical bacterial and viral pneumonia based on history, physical exam findings, and diagnostic testing.Assess the current evidence for antibiotic treatment of Mycoplasma pneumoniae and justify treatment decisions based on patient presentation, severity, and potential complications.

As always, I’m your host, Brad Sobolewski, and today we’re focusing on a pathogen that has been making waves in pediatric emergency departments across the country. Mycoplasma pneumoniae. Whether you know it or not, you’ve likely seen a surge where you work. Patients are presenting with community acquired pneumonia that isn’t responding to standard beta lactam antibiotics, or with parents who are just concerned that their child has walking pneumonia. That’s because mycoplasma pneumonia is just a little bit different than most of the pathogens that we deal with in children. So let’s dive in. So, what is it? Microbiology lecture. Warning, med school trigger. Uh, so Mycoplasma pneumoniae is a small, obligate intracellular bacterium and it lacks a cell wall. So that’s why it doesn’t respond to beta lactam antibiotics like penicillin and amoxicillin and cephalosporins. Instead, it requires macrolides, tetracyclines, or fluoroquinolones for treatment. It’s spread via respiratory droplets and thrives in crowded environments such as schools and daycare centers. It binds to the epithelial cells in the upper and lower respiratory tract, triggering an immune response that leads to mucosal damage, increased mucus production, and impaired gas exchange. So mycoplasma pneumonia infections have been on the rise, especially in children. After a lull during the COVID 19 pandemic, cases reemerged in 2023 and continued to climb into 2024. Historically, mycoplasma pneumonia has been most common in children aged 5 to 17 years and young adults. But what’s new is that we’ve seen a striking increase in infections among children aged 2 to 4. Per the CDC, diagnosed mycoplasma infections increased steadily through the summer of 2024, peaking in August for 2 to 4 year olds and 5 to 17 year old age groups. There’s also been an increase in diagnosis in those under 12 months of age. This is all notable because these infections have historically been thought to affect school aged children much, much more than younger children. All right, let’s talk about clinical features. So the incubation period for mycoplasma pneumonia can be around two to three weeks. Symptoms often start gradually, with fever, headache, malaise, and sore throat, preceding the onset of a persistent dry cough. Unlike classic or typical bacterial pneumonia, which has abrupt onset in focal lung findings, mycoplasma pneumonia patients often present with a prolonged worsening cough that can persist for weeks to months. The name walking ...
