Abstract Purpose To date, a total of 13 probiotic Bacillus species are considered as Generally Recognized Safe organism (GRAS) approved by the US Federal Food, Drug, and Cosmetic Act (FDCA), which used for food feed additives. However, velezensis is not candidate in swine farming due to lack genetic basis action-related traits. Therefore, present study was undertaken exploit underlying traits B...

BACKGROUND Helicobacter pylori has a reduced genome and lives in a tough environment for long-term persistence. It evolved with its particular characteristics for biological adaptation. Because several H. pylori genome sequences are available, comparative analysis could help to better understand genomic adaptation of this particular bacterium. PRINCIPAL FINDINGS We analyzed nine H. pylori gen...

To study the expression of the Autographa californica nuclear polyhedrosis virus (AcNPV) genome, intracellular virus-specific proteins and mRNAs were pulsed-labeled, extracted, and analyzed at 6-h intervals during the replicative cycle. Most RNAs were detected between 12 and 24 h postinfection (p.i.), but many continued to be synthesized until late in infection. Polyhedrin and p8 mRNAs were the...

objective: despite availability of an effective vaccine against hepatitis b virus (hbv), the global prevalence of this virus infection has not diminished significantly. contrary to numerous other human viruses, hbv does not have the ability to propagate in cell culture. however, infectious virus has been produced by transfection of human hepatoma cells with plasmids that contain full length hbv...

Boreal coniferous species with wide geographic distributions show substantial variation in autumn cold acclimation among populations. To determine how this variation is inherited across generations, we conducted a progeny test and examined the development of cold hardening in open-pollinated second-generation (F2) progeny of Abies sachalinensis. The F1 parents had different genetic backgrounds ...

introduction and aims: h. pylori has been implicated in peptic diseases, some with detrimental consequences such as ulcer or cancer. since considerable genetic heterogeneity has been observed within h. pylori population worldwide, it appears an ideal achievement to recruit pcr-based methods and design genetic markers which recognize isolates from normal and symptomatic individuals. in this stud...
