Abstract
Background: African swine fever (ASF) is an important disease affecting swine and has a significant economic loss on both the developed and developing world. Previous studies have indicated the mitigation of African swine fever virus (ASFV) in feed, suggesting that the risk of ASFV transmissibility via the oral exposure.
Aim: We evaluated the potential effects of MCFAs in both individual and synergistic forms, to prevent and/or reduce ASFV infection using in vitro feed model.
Methods: The cytotoxicity of MCFAs on PAM cells were evaluated by using the MTT assay. The potential effects of MCFAs, including C8, C6-C8-C10 (1:1:1 ratio) and C8-C10-C12 (1:1:1 ratio) against a field ASFV strain isolated in the Capital Hanoi of Vietnam were further examined by real-time PCR and HAD assays in in vitro feed model.
Results: Our results indicated that all products do not induce the cytotoxicity at the dose of 100 µg/ml and are suitable for further in vitro examination. All tested products have shown a strong antiviral effect against ASFV infectivity at doses of 0.375% and 0.5%. Interestingly, the synergistic MCFAs have shown clearly their potential activities against ASFV in which at lower dose of 0.25%, pre-treatment with product 2 and 3 induced significant increases at the level of Cq value when compared to positive control and/or product 1 (P<0.05). However, the viral titre was not changed after 24h post-inoculation when compared to positive control by HAD assay.
Conclusion: Our findings suggested that all tested products, both individual and synergistic forms of MCFAs, have possessed a strong anti-ASFV effect and this effect is dose- dependence in in vitro feed model. Additionally, synergistic effects of MCFAs are more effective against ASFV when compared to individual form. The further studies focusing on in vivo anti-ASFV effects of MCFAs are important to bring new insight into the mode of ASFV-reduced action by these compounds in swine feed.
