“…In the Pacific, Acropora muricata and A. pulchra had rates of disease progression of 2 ± 0.3 mm/day and 5 mm/day, respectively (Haapkylä et al 2009). These mortality rates were three to seven-fold higher than rates obtained in Caribbean species so far: a) this study (Acropora cervicornis: 0.7±0.2 mm/day), b) previous studies of Acropora (Acropora palmata: 0.51 ± 0.20 mm/day and Acropora cervicornis: 0.33 ± 0.18 mm/day, Rodríguez 2008), and c) nearly ten-fold higher than that of Agaricia tenuifolia (0.26 ± 0.08 mm/day, Rodríguez et al 2009). These results support that Halofolliculina infection represents an important threat to the survivorship of coral reefs in the Caribbean and in the Indo-Pacific.…”

Caribbean ciliate infection (CCI) and white band disease (WBD) are diseases that affect a multitude of coral hosts and are associated with rapid rates of tissue losses, thus contributing to declining coral cover in Caribbean reefs. In this study we compared tissue mortality rates associated to CCI in three species of corals with different growth forms: Orbicella faveolata (massive-boulder), O. annularis (massive-columnar) and Acropora cervicornis (branching). We also compared mortality rates in colonies of A. cervicornis bearing WBD and CCI. The study was conducted at two locations in Los Roques Archipelago National Park between April 2012 and March 2013. In A. cervicornis, the rate of tissue loss was similar between WBD (0.8±1 mm/day, mean ± SD) and CCI (0.7±0.9 mm/day). However, mortality rate by CCI in A. cervicornis was faster than in the massive species O. faveolata (0.5±0.6 mm/day) and O. annularis (0.3±0.3 mm/day). Tissue regeneration was at least fifteen times slower than the mortality rates for both diseases regardless of coral species. This is the first study providing coral tissue mortality and regeneration rates associated to CCI in colonies with massive morphologies, and it highlights the risks of further cover losses of the three most important reef-building species in the Caribbean.

“…Another ciliate of the genus Halofolliculina was found from the Caribbean (Cróquer et al 2006a), although it appears to be a different species to the one found in the Indo-Pacific (Cróquer et al 2006b). Therefore SEB is considered an Indo-Pacific disease and its Caribbean variation is called Caribbean ciliate infection (Rodríguez et al 2009). …”

In the present study we investigated inter-annual coral disease dynamics, in situ disease progression rates, and disease-associated coral tissue mortality in the Wakatobi Marine National Park (WMNP) situated in the coral triangle in South-East Sulawesi, Indonesia. In 2005, only 2 known syndromes were recorded within the sampling area transect surveys: white syndrome (WS; 0.42% prevalence) and growth anomalies (GA; 0.15% prevalence), whilst 4 diseases were recorded in 2007: WS (0.19%), Porites ulcerative white spot disease (PUWS; 0.08%), GA (0.05%) and black band disease (BBD; 0.02%). Total disease prevalence decreased from 0.57% in 2005 to 0.33% in 2007. In addition to prevalence surveys, in situ progression rates of 4 diseases were investigated in 2007: BBD on Pachyseris foliosa, P. rugosa and Diploastrea heliopora, WS on Acropora clathrata, and brown band (BrB) and skeletal eroding band (SEB) diseases on Acropora pulchra. BrB and WS had the highest progression rates, 1.2 ± 0.36 and 1.1 ± 0.07 cm d -1 , respectively, indicating that diseases may have a significant impact on local Acropora populations. BBD had the lowest progression rate (0.39 ± 0.14 cm d -1). WS caused the most severe recorded total tissue mortality: 53 923 cm 2 over a period of 36 d. Sedimentation and coral cover were studied and a highly significant drop in coral cover was observed. This study provides the first documentation of spatio-temporal coral disease dynamics from Indonesia. Despite low total disease prevalence, progression rates comparable to the ones observed in the Caribbean and Australia indicate that diseases may threaten the reef framework in some locations and add to the degradation of coral reefs in a region already at high risk from anthropogenic impacts.

“…Overall, high variability in disease prevalence was found at all spatial scales for each of the 6 major reefbuilding genera considered, with significant interaction between sites (nested in country) and habitat (depth interval) (F = 1.4, df = 12, p = 0.004) ( Rodríguez et al 2009]) which explained the spatial patterns (Table 2).…”

Geographic assessments of coral/octocoral diseases affecting major reef-building genera and abundant reef species are important to understand their local and geographic spatial-temporal variability and their impact. The status and spatial variability of major Caribbean coral/octocoral diseases affecting important reef-building coral (Montastraea, Diploria, Siderastrea, Stephanocoenia, Porites, and Agaricia) and common, widespread octocoral genera (Gorgonia and Pseudopterogorgia) was assessed along 4 permanent 10 × 2 m band-transects in each of 3 depth habitats (< 4, 5-12 and >15 m) on 2 reefs in 6 countries across the wider Caribbean during the summer and fall of 2005. A permutational multivariate analysis of variance was used to test the spatial variability (countries, reef sites and depth habitats) in prevalence of major diseases in these genera. We found a significant interaction of disease prevalence in the different coral and octocoral genera between reef sites and habitats (depth intervals). Montastraea was primarily affected by both white plague (WP-II) and yellow band disease in deep (16.9 ± SE 16% and 16.9 ± SE 2.3%) and intermediate (8.1 ± SE 1.6% and 15.5 ± SE 2.3%) depth habitats of Culebrita (Puerto Rico) and Chub Cut (Bermuda), respectively. Prevalence of multiple diseases simultaneously and other compromised-health problems affecting Montastraea colonies varied between 0.2 to 2% and 0.2 to 1.8%, respectively. Agaricia and Diploria were mostly affected by WP-II (0.5 to 16%), black band disease (0.4 to 5%) and Caribbean ciliate infections (0.2 to 12%). Siderastrea and Stephanocoenia were mainly affected by dark spots disease in Curaçao, with higher prevalence in intermediate (40.5 ± SE 6.2%) and deep (26.6 ± SE 4.2%) habitats. Aspergillosis and other compromised-health conditions affected Gorgonia ventalina (0.2 to 8%) and other common and widespread octocoral genera (1 to 14%), respectively.
