Summary
Toxic strains of Microcolus Lyngbyaceus, a seaweed, cause stinging dermatitis and swimmer's itch in Hawaii. This organism can also lead to lymphadenopathy and skin infections in affected individuals.
Area of Science:
- Marine Biology
- Dermatology
- Toxicology
Background:
- Microcolus Lyngbyaceus (formerly Lyngbya majuscula) is a filamentous alga known for its toxic properties.
- Since the 1950s, this alga has been implicated as the cause of "stinging seaweed" dermatitis in Hawaii.
- This condition is one of several forms of "swimmer's itch" affecting beachgoers.
Purpose of the Study:
- To review the historical recognition and etiological role of Microcolus Lyngbyaceus in stinging seaweed dermatitis.
- To summarize the clinical manifestations associated with exposure to toxic Microcolus Lyngbyaceus strains.
Main Methods:
- Literature review of historical records and scientific publications regarding Microcolus Lyngbyaceus and associated dermatitis.
- Clinical case reporting and analysis of symptoms associated with exposure.
Main Results:
- Toxic strains of Microcolus Lyngbyaceus are confirmed as the causative agent of stinging seaweed dermatitis.
- Clinical presentations include dermatitis, lymphadenopathy, pustular folliculitis, and localized infections.
Conclusions:
- Microcolus Lyngbyaceus is a significant etiological agent of swimmer's itch in Hawaii.
- The alga poses a public health risk, necessitating awareness and potential preventative measures.
