mobacter types in the marine animal floras is emphasized in 

 Table 2A where the representation of these groups in northern 

 and southern Pacific animals is summarized. Despite large differ- 

 ences in their relative abundance, indicating a habitat efi^ect, the 

 groups together make up 63 and 53 per cent of the total flora, 

 respectively. 



The situation v^ith regard to tlie major bacterial genera in 

 vertebrate and invertebrate animals is summarized in Table 2B. 

 Here there is little difference in numbers of Pseudomonas sp., 

 but a lesser representation of Achromobacter sp. in the flora of 

 invertebrate animals which is apparently compensated for by 

 increased occurrence of Flavohacterhun and Micrococcus species. 

 Thus, a minor effect of host (at the phylum level) is apparent. 



The authors found little difference between the bacterial
