Mechanism
+
Physalia Utriculus
Physalia physalis vs Physalia utriculus
Float and Tail
Nematocysts remain active
+
Local effects
Immediate pain and erythema
Progressive pain to draining lymph nodes
Long term scarring unlikely but occurs
+
Local Effects
+
Systemic Effects
Venom
Pore forming in plasma membrane, Ca influx/swelling/lysis2,3
Neuro/cardio toxicity2,4
Potential deaths with Physalia physalis 5,6
Immune Response – immediate and delayed
Hypersensitivity reaction
Previous exposure
Cross reactivity
