The role of lytic bacteriophages in preventing cross contamination of produce has not been evaluated. A cocktail of three lytic phages specific for E. coli O157:H7 (EcoShield™) or a control (phosphate buffered saline, PBS) was applied to lettuce by either; (1) immersion of lettuce in 500 ml of EcoShield™ 8.3 log PFU/ml or 9.8 log PFU/ml for up to 2 min before inoculation with E. coli O157:H7; (...
A library of metal oxide-conjugated polymer composites was prepared, encompassing WO3 -polyaniline (PANI), -poly(N-methylaniline) (PMANI), -poly(2-fluoroaniline) (PFANI), -polythiophene (PTh), -polyfuran (PFu) and -poly(3,4-ethylenedioxythiophene) (PEDOT) which were used as hole selective layers for perovskite solar cells (PSCs) fabrication. We adopted machine learning approaches to predict com...
Field evaluation of various biopesticides viz., Beauveria bassiana, Isaria fumosorosea NBAIR pfu-5, Metarhizium anisopliae, Lecanicillium lecanii, azadirachtin and soapnut powder were carried out against coconut invasive Rugose Spiraling Whitefly (RSW), Aleurodicus rugioperculetus Martin at Ramachandrapuram Ambajipeta (Dr BR Ambedkar Konaseema district, AP) during 2020-21 2021-22. Pooled data a...
Abstract The use of bacteriophages to control the development different bacterioses, including those caused by bacterium Xanthomonas campestris is one most promising areas in field plant protection. At same time, selection active and determination parameters their remains urgent tasks this direction. phage preparations with low initial concentration particles may not only prevent bacterial dise...
BACKGROUND The rVSVΔG-ZEBOV-GP vaccine prevented Ebola virus disease when used at 2 × 107 plaque-forming units (PFU) in a trial in Guinea. This study provides further safety and immunogenicity data. METHODS AND FINDINGS A randomised, open-label phase I trial in Lambaréné, Gabon, studied 5 single intramuscular vaccine doses of 3 × 103, 3 × 104, 3 × 105, 3 × 106, or 2 × 107 PFU in 115 adults an...
The amplification efficiencies of several polymerase chain reaction (PCR) enzymes were compared using real-time quantitative PCR with SYBR Green I detection. Amplification data collected during the exponential phase of PCR are highly reproducible, and PCR enzyme performance comparisons based upon efficiency measurements are considerably more accurate than those based on endpoint analysis. DNA p...
In all organisms, a ribonucleoprotein called the signal recognition particle (SRP) and its receptor (SR) target nascent proteins from the ribosome to the translocon for secretion or membrane insertion. We present the first X-ray structures of an archeal FtsY, the receptor from the hyper-thermophile Pyrococcus furiosus (Pfu), in its free and GDP*magnesium-bound forms. The highly charged N-termin...
