JC Virus Replication at the First Symptoms of Multiple Sclerosis: A Case Report
Multiple sclerosis (MS) is an autoimmune, demyelinating disorder of unknown etiology, in which viruses have been suggested as etiological/triggering agents. The attention to the association between viruses and MS has been rekindled by the development of progressive multifocal leukoencephalopathy in natalizumab-treated MS patients. Here we report the case of a woman with JC virus (JCV) replication in the cerebrospinal fluid, blood and urine collected at the first symptoms of MS and during several follow-up visits. This observation shows that JCV can be associated with MS without a relation with natalizumab treatment, althou...

Immune Reactivity of Synthetic Peptides Originated from Hypervariable Region 1 of Hepatitis C Synthetic Consensuses with Egyptian Sera Infected with Hepatitis C Virus Type 4
We have studied the immune reactivity of hypervariable region 1 (HVR1) of hepatitis C virus (HCV) against HCV immune positive and negative sera. Two published HVR1 consensus nucleotide sequences (Italian and Chinese) were synthesized, and with both of them, a splicing by overlap extension polymerase chain reaction, cloning and sequencing were performed. From the corresponding amino acid sequences, 3 Italian and 1 Chinese HVR1 peptides were selected for synthesis. The 4 peptides (MB1-MB4; GenBank No.: HQ846888-HQ846891) were used to screen 47 and 31 HCV (type 4) immune positive and negative sera, respectively, by enzyme-lin...

Isolation and Characterization of Lytic Phage vB_EcoM_JS09 against Clinically Isolated Antibiotic-Resistant Avian Pathogenic Escherichia coli and Enterotoxigenic Escherichia coli
Conclusions: A novel lytic coliphage named JS09 was isolated from sewage samples of a swine farm in Jiangsu Province, China. It could infect antibiotic-resistant APEC and ETEC. The morphological, genomic, and growth characteristics of JS09 were studied, and this will be helpful for phage therapy in controlling diseases caused by APEC and ETEC.Intervirology 2015;58:218-231 (Source: Intervirology)

4EBP1 Is Dephosphorylated by Respiratory Syncytial Virus Infection
Respiratory syncytial virus (RSV) requires protein biosynthesis machinery to generate progeny. There is evidence that RSV might alter some translation components since stress granules are formed in their host cells. Consistent with these observations, we found that RSV induces dephosphorylation of 4EBP1 (eIF4E-binding protein), an important cellular translation factor. Our results show no correlation between the 4EBP1 dephosphorylation time and the decrease in the global rate of protein synthesis. Interestingly, treatment with rapamycin stimulates virus generation. The results suggest that RSV is a virus that still contain...

One of the Mechanisms to Increase HSV-1 Uptake in HSV-1-Infected, Activated T Lymphocytes Is the Formation of Filopodia
Conclusions: High expressions of viral receptor protein and filopodia formations are the key factors that enhance the HSV-1 entry into activated T lymphocytes, resulting in an increased production of the virus.Intervirology 2015;58:209-217 (Source: Intervirology)

Partial Sequence of a Novel Virus Isolated from Pelodiscus sinensis Hemorrhagic Disease
Outbreaks of hemorrhagic syndrome-like disease with high mortality rates have frequently occurred in Pelodiscus sinensis farms. The purpose of this study was to investigate the pathogen through challenge infection assays and partial sequencing of the genome of the pathogen. A 453-bp amplicon was obtained by random PCR using the nucleic acid extracted from the tissue homogenate filtrate and showed 32% identity at the amino acid level with the replicase polyprotein of the porcine reproductive and respiratory syndrome virus by Blastx. Multiple alignments indicated the putative protein sequence has some similarities to the rep...
