Abstract:
Lactobacillus species have been widely used in both human and animals to prevent or treat gastrointestinal disorders. Recently, it was reported that Lactobacillus spp. inhibited infections by respiratory and gastroenteric viruses; however, its mechanism is not clear. Lactobacillus spp. play direct and indirect roles in the inhibitory effects of viral replication. 1) In vitro study: Highest protection effects were showed with the known probiotics L. rhamnosus GG (LGG) and L. casei Shirota against both rotavirus (RV) and transmissible gastroenteritis virus (TGEV). 2) In vivo study: L. acidophilus had significant immunopotentiating effects, and was therefore recommended for use as a safe oral adjuvant for rotavirus vaccines in pigs. Oral administration of lactobacilli, such as LGG and L. gasseri, might protect a host animal from influenza virus (IFV) infection. Polysaccharides are regarded to be potentially useful and biologically active as an ingredient for pharmaceutical uses due to a variety of biological activities. Especially, sulphated polysaccharides exhibit broad-spectrum antiviral activity against enveloped viruses in vitro. With respect to human immunodeficiency virus type 1 (HIV-1), its in vitro antiviral activity is, specifically, the inhibition of virus-cell attachment, the first step in the infection process. Recently, it was reported that sulphated polysaccharides exhibited antiviral activity against HBV, HCMV, HSV and IFV. In conclusion, Lactobacillus spp. and polysaccharides with antiviral activity against diverse viruses are potential candidates as ingredients for probiotics and medicine candidate for the prevention and treatment of viral infections in animals and humans.
