Detection of FMD Infection in Vaccinated Animals
The most direct method to detect FMD infection in vaccinated animals is to look for the FMD virus. However, the acute phase of virus replication may be transient and in the absence of clinical signs, the chance of detecting this is small. The proportion of vaccinated ruminants that go on to become persistently infected is variable as is the duration of virus carriage. Persistently infected anim...
متن کاملEffect of IL-2 co-expressed or co-inoculated with immuno-dominant epitopes from VP1 protein of FMD virus on immune responses in BALB/c mice
Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...
متن کاملHumoral immune response against two surface antigens of Chlamydia pecorum in vaccinated and naturally infected sheep
Chlamydia pecorum is a globally recognised livestock pathogen due to the significant clinical and economic impact it poses to livestock producers. Routine serological diagnosis is through a complement fixation test (CFT), which is often criticised for cross-reactivity, poor sensitivity and specificity. Although serology remains the preferred method in veterinary diagnostic laboratories, serolog...
متن کاملThe Epidemiology of Fmd
FMD virus is an aphtovirus within the picornaviridae family. The most important characteristics in the epidemiology of the disease include the rapid growth of the virus, its stability under a variety of conditions and the occurrence of serotypes (Donaldson, 1991). There are seven serotypes and several subtypes within each. The infections caused by different serotypes are clinically indistinguis...
متن کاملEvaluation of the efficacy of a new oil-based adjuvant ISA 61 VG FMD vaccine as a potential vaccine for cattle
Foot-and-mouth disease is an important viral disease of cloven-hoofed animals. Inactivated whole particle virus vaccines are still widely used in prophylactic vaccination campaigns. The choice of adjuvant is a very important factor in enhancing immune responses and the efficacy of inactivated vaccines. Montanide ISA 61 VG is a new ready-to-use mineral oil-based adjuvant developed by SEPPIC Inc....
