gene therapy as a modern therapeutic approach has not yet advanced to a globally-approved therapeutic approach. lack of adequate reliable gene delivery system seems to be one of the major reasons from the pharmaceutical biotechnology point of view. main obstacles delaying successful application of human gene therapy are presented in this review. the unique advantages of non-biological gene carr...
The role of foot-and-mouth disease virus (FMDV) carrier cattle in causing new outbreaks is still a matter of debate and it is important to find out these carrier animals by post-outbreak serosurveillance to declare freedom from FMDV infection. In this study we explore the differences in viral shedding between carrier and non-carrier animals, quantify the transmission rate of FMDV infection from...
Although replication-competent oncolytic viral vectors have been developed to improve antitumor activity, the generation of high titers of neutralizing antibodies inhibits repetitive viral infection. Many studies have reported that oncolytic virus-infected carrier cells can overcome this viral induced immunogenicity. However, the effects of oncolytic virus-infected carrier cells in human oral s...
Crowell, Richard L. (Hahnemann Medical College, Philadelphia, Pa.). Specific viral interference in HeLa cell cultures chronically infected with Coxsackie B5 virus. J. Bacteriol. 86:517-526. 1963.-The presence of large amounts of Coxsackie B5 virus in culture fluids of a HeLa subline, serially propagated over a 3-year period, provided evidence for attainment of a viral carrier state. Human serum...
Although outbreaks are uncommon, equine viral arteritis is an important disease because of the potential risk of abortion in mares and establishment of the carrier state in a relatively high percentage of infected stallions. Equine arteritis virus carrier stallions constitute an important reservoir of infection, and appropriate precautions have to be taken when nonimmunized mares are inseminate...
Several foot-and-mouth disease virus (FMDV) carrier cattle were identified in Vietnam by the recovery of infectious virus from oropharyngeal fluid. This report contains the first near-complete genome sequences of seven viruses from sequential samples from one carrier animal collected over the course of 1 year. The characterization of within-host viral evolution has implications for FMDV control...
Introduction: Water can be a carrier environment for pathogens or provide the conditions for the spread of a disease or various infectious cases. Covid-19 outbreak was declared a pandemic by the World Health Organization on 12 March 2020. The main routes of transmission of the virus are through drapelet and individual transmission, although recent research confirms the presence of viral RNA in ...
