The isolation and serotyping of foot-and-mouth disease virus in Iran during 2019-2022.
Foot-and-mouth disease (FMD) is a significant transboundary animal disease that has a considerable economic impact on livestock systems worldwide. In order to determine the presence and type of FMD virus in Iran, a total of 90 samples of vesicular fluid and epithelial tissue were collected from the tongues, tooth pads, and hooves of clinically suspect cattle on 40 vaccinated farms in 9 provinces of Iran. These samples were collected during four years, from January 2019 to December 2022, and the vaccine was a locally produced polyvalent inactivated vaccine. The collected samples were analyzed using ELISA and isolation methods to identify and characterize the FMD virus. The results of the ELISA tests revealed that 66.66% of the samples were positive for FMD, and the serotypes of the virus were determined. Considering ELISA reslut, 62% of the samples were assigned to serotype O, 33% to serotype A, and 5% to serotype Asia-1. Furthermore, 90% of the positive samples were inoculated onto monolayer cultures of pig kidneys (IB-RS2) for isolation and antigen detection by serotype-specific ELISA kit. The great majority of detected serotype O viruses were from Esfahan province, while the most detected serotype A and serotype Asia-1 viruses were from Qom and Tehran provinces, respectively. These findings indicate that the ELISA and isolation methods are suitable for identifying and typing FMD viruses. The vaccination program in Iran, which includes three serotypes (O, A, and Asia-1), appears to be effective in controlling the spread of the disease. However, the continued circulation of these serotypes in most provinces suggests that ongoing surveillance and vaccination efforts are necessary.
期刊介绍:
Viruses are convenient models for the elucidation of life processes. The study of viruses is again on the cutting edge of biological sciences: systems biology, genomics, proteomics, metagenomics, using the newest most powerful tools.
Huge amounts of new details on virus interactions with the cell, other pathogens and the hosts – animal (including human), insect, fungal, plant, bacterial, and archaeal - and their role in infection and disease are forthcoming in perplexing details requiring analysis and comments.
Virus Genes is dedicated to the publication of studies on the structure and function of viruses and their genes, the molecular and systems interactions with the host and all applications derived thereof, providing a forum for the analysis of data and discussion of its implications, and the development of new hypotheses.
