The dermis of cetaceans is in constant contact with microbial species. Although the skin of the bottlenose dolphin provides adequate defense against most disease-causing microbes, it also provides an environment for microbial community development. Microbial community uniqueness and richness associated with bottlenose dolphin skin is a function of varying habitats and changing environmental conditions. The current study uses ribosomal DNA as a marker to identify bacteria found on the skin of coastal and offshore bottlenose dolphins off of Southern California. The unique microbial communities recovered from these dolphins suggest a greater microbial diversity on the skin of offshore ecotype bottlenose dolphins, while microbial populations associated with the coastal ecotype include species that are more closely related to each other and that suggest exposure to communities that are likely to be associated with terrestrial runoff.
鲸类动物的真皮层与微生物物种不断接触。虽然宽吻海豚的皮肤足以抵御大多数致病微生物，但它也为微生物群落的发展提供了环境。与宽吻海豚皮肤相关的微生物群落的独特性和丰富性是由不同的栖息地和不断变化的环境条件决定的。本研究使用核糖体 DNA 作为标记物，以鉴定在加利福尼亚南部沿海和近海宽吻海豚皮肤中发现的细菌。从这些海豚身上回收的独特微生物群落表明，近海生态型宽吻海豚皮肤的微生物多样性更大，而与沿海生态型相关的微生物种群包括彼此之间关系更密切的物种，这表明它们接触到的群落可能与陆地径流有关。
