Immunity of Foot-and-Mouth Disease Serotype Asia 1 by Sublingual Vaccination
نویسندگان
چکیده
Foot-and-mouth disease virus (FMDV) causes vesicular disease of cloven-hoofed animals, with severe agricultural and economic losses. Here we present study using a sublingual (SL) route with the killed serotype Asia 1 FMDV vaccine. Guinea pigs were vaccinated using a commercially available vaccine formulation at the manufacturer's recommended full, 1/4, and 1/16 antigen doses. Animals were challenged with homologous FMDV Asia1 strain at various times following vaccination. All control guinea pigs exhibited clinical disease, including fever, viremia, and lesions, specifically vesicle formation in feet. Animals vaccinated with the 1/16 and 1/4 doses were protected after challenge at days 7, 28, and 35 post vaccination. These data suggest that effective protection against foot-and-mouth disease can be achieved with 1/16 of the recommended vaccine dose using SL vaccination, indicating that the sublingual route is an attractive alternative for the administration of the FMDV vaccine.

Foot-and-mouth disease virus (FMDV) serotypes O, A and Asia1 are responsible for a significant number of disease outbreaks in Iraq. The current study can be considered as the first molecular characterization of serotype Asia1 in Iraq. The present investigation reports the detection of serotype FMDV Asia1 from local farms in Sulaimani districts in 2012 and 2014 outbreaks. Phylogenetic analysis o...

Foot and mouth disease (FMD) is a contagious animal disease that causes irreparable damage to the economy of countries, including Iran in which this disease is a native one. Among the ways to combat FMD are vaccination and slaughter. Due to the specific situation of Iran, it is not possible to kill infected animals. Therefore, vaccination is the most important way to fight this disease. S...

Regular vaccinations with potent vaccine, in endemic countries and vaccination to live in non-endemic countries are the methods available to control foot-and-mouth disease. Selection of candidate vaccine strain is not only cumbersome but the candidate should grow well for high potency vaccine preparation. Alternative strategy is to generate an infectious cDNA of a cell culture-adapted virus and...
متن کاملFoot and Mouth Disease
Foot and mouth disease (FMD) is the most contagious disease of mammals and has a great potential for causing severe economic loss in susceptible cloven-hoofed animals. There are seven serotypes of FMD virus (FMDV), namely, O, A, C, SAT 1, SAT 2, SAT 3 and Asia 1. Infection with one serotype does not confer immunity against another. FMD cannot be differentiated clinically from other vesicular di...
