Characterization and optimization of abamectin-a powerful antiparasitic from a local Streptomyces avermitilis isolate.

Abamectin (ABA) constitutes a big commodity for pharmaceutical companies because it generates about one billion dollar annual sale. Avermectins (AVMs) and their naturally occurring analogues, milbemycins (MILs), meilingmycins (MEIs), ivermectin (IVE), abamectin (ABA), and nemadectin (NEM), represent one of the most developed antiparasitic agents. Abamectin is a mixture of avermectin B1a and avermectin B1b.

Whole-genome sequencing of human Pegivirus variant from an Egyptian patient co-infected with hepatitis C virus: a case report.

Background: Human pegivirus (HPgV) is structurally similar to hepatitis C virus (HCV) and was discovered 20 years ago. Its distribution, natural history and exact rule of this viral group in human hosts remain unclear. Our aim was to determine, by deep next-generation sequencing (NGS), the entire genome sequence of HPgV that was discovered in an Egyptian patient while analyzing HCV sequence from the same patient.

Isolation, characterization, cloning and bioinformatics analysis of a novel receptor from black cut worm () of vip 3Aa toxins.

Black cutworm (BCW) is an economically important lepidopteran insect. The control of this insect by a Bt toxin and the understanding of the interaction between the Bt toxin and its receptor molecule were the objectives of this research work. A gene coding for a Vip3A receptor molecule was identified, characterized, and cloned, from the brush border membrane vesicles (BBMV) of the BCW.

First report of detection of the putative receptor of toxin Vip3Aa from black cutworm ().

Black cutworm (BCW) , an economically important lepidopteran insect, has attracted a great attention. (Bt) is spore forming soil bacteria and is an excellent environment-friendly approach for the control of phytophagous and disease-transmitting insects. In fact, bio-pesticide formulations and insect resistant transgenic plants based on the bacterium Bt delta-endotoxin have attracted worldwide attention as a safer alternative to harmful chemical pesticides.
