Most sequenced bacteria possess mechanisms to import choline and glycine betaine (GB) into the cytoplasm. The primary role of choline in bacteria appears to be as the precursor to GB, and GB is thought to primarily act as a potent osmoprotectant. Choline and GB may play accessory roles in shaping microbial communities, based on their limited availability and ability to enhance survival under st...

AIM Bacteria associated with harmful algal blooms can play a crucial role in regulating algal blooms in the environment. This study aimed at isolating and identifying algicidal bacteria in Dinoflagellate culture and to determine the optimum growth requirement of the algicidal bacteria, Loktanella sp. Gb-03. MATERIALS AND METHODS The Dinoflagellate culture used in this study was supplied by Pr...

The reniform nematode (Rotylenchulus reniformis Linford & Oliveira) is an important problem in U.S. cotton, and all cultivars support high R. reniformis populations. The objectives of this research were to find better sources of resistance to R. reniformis than are known within G. hirsutum L. and G. barbadense L. and to determine if any of these sources are also resistant to the root-knot nemat...

ABSTRACT Human cytomegalovirus (HCMV) glycoproteins gB and gH/gL are both necessary and sufficient for cell-cell fusion. However, it is not clear what roles these glycoproteins play in virus entry, whether acting directly in membrane fusion or in binding receptors. With other herpesviruses, it appears that gB is the fusion protein and is triggered by gH/gL, which, in some cases, binds receptors...

On the basis of sequence variation in the UL55 gene that encodes glycoprotein B (gB), human cytomegalovirus (CMV) can be classified into 4 gB genotypes. The goal of the present study was to determine the distribution of CMV gB genotypes and the effect of gB type on clinical outcomes in a cohort of immunocompromised patients, including both transplant recipients and nonrecipients. The distributi...

Following herpes simplex virus type 1 (HSV-1) ocular infection of C57BL/6 mice, activated CD8(+) T cells specific for an immunodominant epitope on HSV-1 glycoprotein B (gB-CD8 cells) establish a stable memory population in HSV-1 latently infected trigeminal ganglia (TG), whereas non-HSV-specific CD8(+) T cells are lost over time. The retention and activation of gB-CD8 cells appear to be influen...

Received 18 May 2004 Revised 3 September 2004 Accepted 7 September 2004 Using an established spotted cDNAmicroarray platform, the nature of changes in the transcriptional profiles of 2200 unique genes from the chestnut blight fungusCryphonectria parasitica in response to the absence of either the Ga subunit CPG-1 or the Gb subunit CPGB-1 has been explored. It is reported that 216 transcripts we...

UNLABELLED Infectious laryngotracheitis (ILT) is a highly contagious acute respiratory disease of chickens caused by infectious laryngotracheitis virus (ILTV). The disease is controlled mainly through biosecurity and vaccination with live attenuated strains of ILTV and vectored vaccines based on turkey herpesvirus (HVT) and fowlpox virus (FPV). The current live attenuated vaccines (chicken embr...
