Summary
Cutaneous leishmaniasis, a skin infection, can be difficult to diagnose in non-endemic areas. Polymerase chain reaction (PCR) testing identified Leishmania braziliensis in a patient with a non-healing ulcer, leading to effective treatment.
Area of Science:
- Dermatology
- Infectious Diseases
- Parasitology
Background:
- Cutaneous leishmaniasis is a parasitic skin infection transmitted by sandflies.
- Diagnosis can be challenging in individuals outside endemic regions.
- Non-healing skin ulcers require consideration of leishmaniasis.

Overview
01:25Rapid Identification of Pathogens
MALDI-TOF MS has transformed clinical microbiology by offering a rapid and reliable method for pathogen identification. The traditional approach to microbial identification typically involves time-consuming culture techniques and biochemical tests, which can delay the initiation of appropriate antimicrobial therapy. MALDI-TOF MS avoids these delays by using characteristic ribosomal protein mass patterns of microbial cells, enabling accurate species-level identification within minutes.Principle...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
