What is Botryomycosis? The Rare Bacterial Infection That Mimics Fungus
Published: Nov 28, 2023
Botryomycosis is an uncommon bacterial infection that creates grape-like clusters in the body. Despite its name suggesting a fungal origin, it's actually caused by bacteria and can affect both the skin and internal organs.
Signs and Symptoms: From Skin to Organs
Botryomycosis primarily affects the skin, causing slow-growing nodules, wartlike growths, or non-healing ulcers. These lesions may drain pus containing small yellow grains. In rarer cases, it can affect internal organs like the lungs, liver, or brain, leading to symptoms like cough, abdominal pain, or neurological issues.
Who's at Risk?
While anyone can develop botryomycosis, it's more common in people with weakened immune systems. Risk factors include conditions like HIV, diabetes, and cystic fibrosis. Trauma or surgery can also increase the risk by allowing bacteria to enter the body.
Diagnosis: Peeling Back the Layers
Diagnosing botryomycosis can be tricky as it mimics other conditions. Doctors typically examine pus or tissue samples under a microscope and perform cultures to identify the bacteria. They may also use imaging tests like X-rays or CT scans to assess internal infections.
Treatment: A Two-Pronged Approach
Treatment usually involves a combination of antibiotics and surgery. The type and duration of antibiotics depend on the specific bacteria causing the infection. For skin infections, treatment may last a few weeks, while internal infections might require months of therapy. Surgical removal of infected tissue is often necessary, especially for deep or stubborn infections.
