| Abstract | Ceratomyxa sparusaurati infection was studied in gilthead sea bream from different mariculture systems of Spain. Culture conditions were found to influence the infection dynamics. Total prevalences ranged from 0 in a closed system to 59.9% in a Mediterranean semi-intensive farm. Prevalence was significantly lower in summer in a restricted group from the latter system, but no clear seasonal pattern was observed in the remaining fish groups in any system. A statistically significant dependence between infection prevalence and host weight was observed in some fish groups. Different degrees of histopathological damage were noted in the infected gallbladders, mainly involving swelling, vacuolization, and sloughing of the epithelial cells. Transmission electron microscope observations of the infected tissues demonstrated a characteristic protrusion of the epithelial cell surface and mitochondrial alterations. In fish from stocks showing external disease signs and trickling mortalities, parasite stages invaded other organs and were responsible for cell-mediated host reaction and important tissue injuries. Therefore, C. sparusaurati can be considered a potential threat for some Sparus aurata-growing systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
