Bako Diagnostics developed a BakoDx Web Space PCR (polymerase chain reaction) test to identify the infectious agents involved in web space dermatitis. This highly sensitive, highly specific test provides podiatric clinicians with ease of use, rapid results, and accurate diagnostics, allowing for the best patient care. The test utilizes real-time PCR (RT-PCR) technology to detect the causative agent within the web space keratin when present, resulting in the clinically identified dermatitis. The BakoDx Web Space panel tests for fungi (dermatophytes, Candida spp) and bacteria (Corynebacterium minutissimum, gram-negative bacteria, and staphylococcus aureus, which, if positive, a reflex test is performed for the mecA gene of methicillin-resistant staphylococcus aureus [MRSA]). Interdigital infectious dermatitis may be due to a variety of organisms that may look similar, but their treatment differs. Differential diagnosis may include Corynebacterium minutissimum in erythrasma, tinea pedis, candidal intertrigo, and/or primary or secondary bacterial infections.
