Phylogenetic study on Microcotyle sp. (Monogenea) from common dentex (Dentex dentex) in the Mediterranean Sea, Greece

The monogenean Microcotyle sp. was isolated from common dentex in the Sea of Crete, the part of the Mediterranean Sea. The 28S rRNA gene of Microcotyle sp. was amplified by polymerase chain reaction (PCR). The PCR product was sequenced and compared with other 28S rRNA sequences of Monogenea. Phylogenetic analyses were performed with neighbour-joining (NJ), minimum evolution (ME), maximum likelihood (ML) and maximum...

Status of cassava mosaic disease and whitefly population in Zambia

Cassava mosaic disease is the most important disease affecting cassava in Zambia. A study was conducted through a survey to determine the status of cassava mosaic disease incidence, severity and whitefly abundance in farmers’ fields in six provinces: Lusaka, Northern, North-Western, Luapula, Eastern and Western between March and May 2014. The study reveals that cassava mosaic disease incidence was highest in...

Polymers selection for a liquid inoculant of Azospirillum brasilense based on the Arrhenius thermodynamic model

Plant growth promoting bacteria (PGPB) enhances the growth of their hosts and can protect them from biotic and abiotic stresses. Bacterial inoculants contain one or more of these beneficial strains in a carrier material, which must be able to maintain the viability of the cells during the time of storage, and also guarantee the biological activity of the strains once applied in the soil. These inoculants can be solid,...

Biosynthesis of silver nanoparticles by plants crude extracts and their characterization using UV, XRD, TEM and EDX

Plant extracts are very cost effective and eco-friendly, thus, can be an economic and efficient alternative for the large-scale synthesis of nanoparticles. The preparation of stable, uniform silver nanoparticles by reduction of silver ions with Emblica officinalis, Terminalia catappa and Eucalyptus hybrida extract is reported in the present paper. It is a simple process of global research interest for obtaining silver...

Biochemical profile of cuttings used for in vitro organogenesis of Prunus africana: An endangered species in Cameroon

Prunus africana (Kanda stick) is a valuable medicinal tree classified as priority species for domestication in Cameroon. To measure the ability for developing axillary buds and multiple shoots in relation with the origin and state of explants, some biochemical parameters were assessed in eight types of single-node cuttings. These cuttings were treated with different concentrations of kinetin (kin) indole butyric acid...

Liver histopathology in bovine Fascioliasis

The livers of slaughtered cattle were examined by visualization, palpation and incision. Macroscopically, some of the infected livers appeared to be slightly swollen with pale color at the round edges, while some appeared greatly swollen, with a few small irregular whitish areas indicating fibrosis over the parietal surface. In some cases, the capsule was thick and rough with whitish or reddish discoloration and...
