Molecular Identification of Some Schistosoma mansoni Isolates in Saudi Arabia

چکیده
In this paper, nine geographical isolates of Schistosoma mansoni (three from Egypt, three from Saudi Arabia and 3 from Puerto Rico) were studied at the genotype level by RAPD analysis with two arbitrary primers. The genetic distance was measured by the percentage of unshared bands. The RAPD results showed that the Egyptian strains were closely related to Saudi strains but Puerto Rico strains clustered in different group. These results demonstrated the usefulness of RAPD for displaying the differences of interand intra-species of Schistosoma. It also suggested that genetic diversity among different geographical strains of Schistosoma mansoni from different localities had occurred.

Review of Using Plants as Molluscicidal, Larvicidal and Schistosomicidal in Saudi Arabia
Schistosomiasis, generally identified as Bilharzia, is an earliest human disease, Schistosoma mansoni is transmitted by the aquatic pulmonate snails of the genus Biomphalaria. Intestinal schistosomiasis due to infection with Schistosoma mansoni have been known in Saudi Arabia. Also, the urinary schistosomiasis has been reported in Saudi Arabia since 1887, absolutely certain members of the genus...

The identification of snails of the genus Biomphalaria can be done using morphological characteristics which depends on the size of the snails and skill and knowledge of researcher. These methods sometimes are not adequate for identification of species. The PCR-RFLP, using the ITS region of the rDNA, has been used to identify Brazilian species of the genus Biomphalaria. Nevertheless, there is a...
متن کاملFirst morphogenetic identification of the fungal pathogen Colletotrichum musae (Phyllachoraceae) from imported bananas in Saudi Arabia.
Colletotrichum musae is the causal agent of anthracnose in banana fruits; infection by this fungal pathogen results in severe post-harvest losses. Eleven C. musae isolates were obtained from infected imported banana fruit samples with anthracnose lesions collected from different markets in Riyadh, Saudi Arabia. The pathogenic, morphological, cultural, and molecular characteristics of these C. m...
