Summary
Colonies of the bryozoan speciesHippodiplosia insculpta collected from Grandmother’s Cove (American Camp, San Juan Island, Washington, USA) were analyzed in view of pathologic growth patterns. The species produced giant buds that were filled with extracellular polymeric substances and a dense microbial biofilm consisting of bacteria and fungal hyphae. Fungi were isolated from the colonies and were identified asPenicillium expansum, Peniillium brevicompactum, Sclerotinia sclerotiorum, Acremonium breve, andCladosporium sphaerospermum. The results of this study indicate that the formation of giant buds in the bryozoan is a defense mechanism against fungal infection.
