| Abstract | The present study was planned to investigate the prevalence of Sarcocystis spp. among slaughtered water buffaloes (Bubalus bubalis) at Alexandria province, Egypt. Three hundred blood samples were collected from slaughtered buffaloes (5-7 years old). Two techniques were used to evaluate the seroprevalence of Sarcocystis spp., enzyme-linked immunosorbent assay (ELISA) and indirect haemagglutination assay (IHA). It was revealed that 203 (67.6 %) and 191 (63.6 %) of the tested serum samples were seropositive to Sarcocystis spp. by ELISA and IHA, respectively. The results of sensitivity and specificity of IHA relative to ELISA were 94 and 100 %, respectively. For molecular characterization of inter- and intra-species genetic polymorphism within Egyptian isolates of Sarcocystis spp. of water buffaloes, polymerase chain reaction (PCR) and polymerase chain reaction-restriction length polymorphisms (PCR-RFLPs) were performed on four macroscopic isolates. The isolates represented two different geographical regions of Egypt, Alexandria and Assuit provinces. Alexandria isolates (large and small-sized cyst of the same host) and Assuit isolates (large and small-sized cyst of the same host) were used. The 18S rDNA of the macroscopic cysts were characterized, in tandem, by four restriction endonucleases, RsaI, MboI, SspI and DraI. RsaI and MboI enzymes did not show any restriction sites for all isolates, leaving the amplified fragments without cutting. SspI showed two fragments in Alexandria and Assuit small-sized isolates cut by the enzyme at 600-700-bp fragments, while Alexandria and Assuit large-sized cysts amplicons were not digested by this enzyme. The fourth enzyme, DraI, cut the PCR product of Alexandria large-sized cysts into two fragments (420-780 bp), while Assuit large-sized amplicon was not cut. It could be concluded that there was a far distance between the two local isolates (small and large sized), but there were no differences between the large-sized isolates. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
