We report on the presence of lobomycosis-like disease (LLD) and nodular skin disease (NSD) in a community of Guiana dolphins (Sotalia guianensis) inhabiting the biologically and chemically contaminated Paranaguá estuary (Brazil) and on their absence in the community living in the cleaner Cananéia estuary. Prevalence rates of LLD and NSD were 3.9% and 12.6%,(More)
