translate English to French: Once the fungus had breached the cuticle, it formed protoplasts that failed to elicit an obvious immune response and multiplied rapidly in the haemocoel and in tissues.
Dès que le champignon franchit la cuticle, il forme des protoplastes, sans engendrer une réaction immunitaire, et se multiplie rapidement dans l'hémolymphe et d'autres tissus.
