Fasciolid flukes are among the largest and best known digenetic trematodes and have considerable historical and veterinary significance. Fasciola hepatica is commonly implicated in causing disease in humans. The origins, patterns of diversification, and biogeography of fasciolids are all poorly known. We have undertaken a molecular phylogenetic study using 28S, internal transcribed spacer 1 and...

Four goats bred in Central Italy (province of Rieti) revealed, in the liver, metacestodes of Echinococcus granulosus. The cysts, unilocular and fertile, were examined by microscopy and molecular diagnostics. Morphological data on the rostellar hooks are in agreement with the original description of the strain found in buffaloes and are largely compatible with those reported in Europe for cattle...

The prevalence of different H. pylori genotypes in various geographical regions indicates region-specific adaptations during the course of evolution. Complete genomes of H. pylori from countries with high infection burdens, such as India, have not yet been described. Herein we present genome sequences of two H. pylori strains, NAB47 and NAD1, from India. In this report, we briefly mention the s...

Little is known on the diversity and public health significance of Echinococcus species in livestock in Egypt. In this study, 37 individual hydatid cysts were collected from dromedary camels (n=28), sheep (n=7) and buffalos (n=2). DNA was extracted from protoscoleces/germinal layer of individual cysts and amplified by PCR targeting nuclear (actin II) and mitochondrial (COX1 and NAD1) genes. Dir...

Echinococcus granulosus sensu lato (s.l.) is a causative agent of cystic echinococcosis or cystic hydatid disease in humans and domestic and wild animals. The disease is a serious health problem in countries associated with poverty and poor hygiene practices, particularly in livestock raising. We introduced a practical algorism for genotyping the parasite, which may be useful to many developing...

The systematics of the poriferan Order Haplosclerida (Class Demospongiae) has been under scrutiny for a number of years without resolution. Molecular data suggests that the order needs revision at all taxonomic levels. Here, we provide a comprehensive view of the phylogenetic relationships of the marine Haplosclerida using many species from across the order, and three gene regions. Gene trees g...

Plant defensins are small, cysteine-rich peptides that possess biological activity towards a broad range of organisms. Their activity is primarily directed against fungi, but bactericidal and insecticidal actions have also been reported. The mode of action of various antifungal plant defensins has been studied extensively during the last decades and several of their fungal targets have been ide...

An epidemiological and molecular survey on the occurrence of Echinococcus hydatid cysts in livestock was conducted in Greece. In total 898 sheep, 483 goats, 38 buffaloes, 273 wild boars and 15 deer were examined and 30.2% (6.45% cyst fertility), 7.86% (3.2% cyst fertility), 42% (7.9% cyst fertility), 1.1% (0% cyst fertility), 0% of them were found infected, respectively. Infection rate in diffe...

The mitochondrial NADH:ubiquinone oxidoreductase complex (Complex I) is a large protein complex formed from both nuclearly and mitochondrially encoded subunits. Subunit ND1 is encoded by a mitochondrial gene comprising five exons, and the mature transcript requires four RNA splicing events, two of which involve trans-splicing independently transcribed RNAs. We have identified a nuclear gene (OT...

Cancer is the second leading cause of mortality worldwide preceded by cardiovascular diseases. The therapeutic approaches for drug developmentinclude use small molecules, antibodies, peptidesor short nucleic acid sequences. peptide-based drugs have been developed to treat many diseases like diseases, cancer, metabolic disorders, immunological and viral infections. More than 80 peptide are alrea...
