It is crucial to understand the microbial community associated with the host when attempting to discern the pathogen responsible for disease outbreaks in scleractinian corals. This study determines changes in the bacterial community associated with Montipora sp. in response to black band disease in Indonesian waters. Healthy, diseased, and dead Montipora sp. (n = 3 for each sample type per location) were collected from three different locations (Pari Island, Pramuka Island, and Peteloran Island). DGGE (Denaturing Gradient Gel Electrophoresis) was carried out to identify the bacterial community associated with each sample type and histological analysis was conducted to identify pathogens associated with specific tissues. Various Desulfovibrio species were found as novelty to be associated with infection samples, including Desulfovibrio desulfuricans, Desulfovibrio magneticus, and Desulfovibrio gigas, Bacillus benzoevorans, Bacillus farraginis in genus which previously associated with pathogenicity in corals. Various bacterial species associated with uninfected corals were lost in diseased and dead samples. Unlike healthy samples, coral tissues such as the epidermis, endodermis, zooxanthellae were not present on dead samples under histological observation. Liberated zooxanthellae and cyanobacteria were found in black band diseased Montipora sp. samples.

This paper analyses the buildings, spaces and interiors of Bangour Village public asylum for the insane, near Edinburgh, and compares these with an English asylum, Whalley, near Preston, of similar early-twentieth-century date. The village asylum, which developed from a European tradition of rendering the poor productive through ‘colonisation’, was more enthusiastically and completely adopted in Scotland than in England, perhaps due to differences in asylum culture within the two jurisdictions. ‘Liberty’ and ‘individuality’, in particular, were highly valued within Scottish asylum discourses, arguably shaping material provision for the insane poor from the scale of the buildings to the quality of the furnishings. The English example shows, by contrast, a greater concern with security and hygiene. These two differing interpretations show a degree of flexibility within the internationalized asylum model which is seldom recognized in the literature.
