Waccnes Containing Bovine Herpe Svirus 1 Attenuated By Mutation In Latency-Related Gene, Clinton J. Jones
Waccnes Containing Bovine Herpe Svirus 1 Attenuated By Mutation In Latency-Related Gene, Clinton J. Jones
School of Veterinary and Biomedical Sciences: Faculty Publications
Vaccines for pathogenic Strains of bovine herpesvirus 1 (BHV-1) which are based on attenuated BHV-1 having a mutation in the latency-related gene are provided. Live, attenuated vaccines are also provided which express anti gens from other viral or bacterial pathogens and thus form the basis of a variety of vaccines.

Porphyromonas gingivalis, an important periodontal pathogen, infects primary gingival epithelial cells (GECs). Despite the large number of bacteria that replicate inside the GECs, the host cell remains viable. We demonstrate that P. gingivalis triggers rapid and reversible surface phosphatidylserine exposure through a mechanism requiring caspase activation. However, after 1 day of infection, the bacteria no longer induce phosphatidylserine externalization and instead protect infected cells against apoptosis. Infection exerts its effect at the level of mitochondria, as P. gingivalis also blocks depolarization of the mitochondrial transmembrane potential and cytochrome c release. Interestingly, protein kinase B/Akt is phosphorylated during infection, which can …

Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko
Pr. Mamoudou H. DICKO, PhD
The latest estimates of the FAO demonstrate the problems of the fight against hunger. These problems are manifested by the ever-increasing number of chronically undernourished people worldwide. Their numbers during the 1999-2001 period were estimated at about 840 million of which 798 million live in developing countries. Sub-Saharan Africa alone represented 198 million of those. In this part of Africa the prevalence of undernourishment ranges from 5-34%, causing growth retardation and insufficient weight gain among one third of the children under five years of age and resulting in a mortality of 5-15% among these children. Malnutrition resulting from undernourishment is …
Phosphorylation Of Vesicular Stomatitis Virus Phosphoprotein P Is Indispensable For Virus Growth†, Subash C. Das, Asit K. Pattnaik

The phosphoprotein (P) of vesicular stomatitis virus (VSV) is an essential subunit of the viral RNAdependent RNA polymerase (RdRp) complex. It is phosphorylated at two different domains. Using defective interfering (DI) RNA or minigenomic RNA templates, we previously demonstrated that phosphorylation within the amino-terminal domain I is essential for transcription, whereas phosphorylation within the carboxyterminal domain II is necessary for replication. For the present study, we examined the role of the phosphorylation of residues in these domains in the life cycle of VSV. Various mutant P coding sequences were inserted into a full-length cDNA clone of VSV, and the virus …
