“…One more potential and effective method to prevent distribution of coronaviral infections is application of probiotic bacteria as they can inhibit viral replication activity and exert an antiviral effect by producing lactic acid, hydrogen peroxide, and bacteriocins (Sekar et al, 2016;Kanmani et al, 2018;Abdelhamid et al, 2019). In addition, the study of feline microbiota has shown that bacteria of the genus Lactobacillus can have an antagonistic effect on the feline intestinal CoV (Mingmongkolchai and Panbangred, 2018), suggesting the necessity of large-scale studies on possible modulation of animal health with probiotics.…”

— Coronaviruses have tremendous evolutionary potential, and three major outbreaks of new human coronavirus infections have occurred in the recent history of humankind. In this paper, the patterns of occurrence of new zoonotic coronavirus infections and the role of bioveterinary control in preventing their potential outbreaks in the future are determined. The possibility of SARS-CoV-2 infection in companion animals is considered. Diverse human activities may trigger various interactions between animal species and their viruses, sometimes causing the emergence of new viral pathogens. In addition, the possibility of using probiotics for the control of viral infections in animals is discussed.

“…In addition, the main functions of the enzymes are increase of digestion (infection time the shrimp not taking feeds) and the reduction of mortality rate. Previous research [14] has reported protease producing Bacillus sp. Mk22 which enhanced shrimp survivals and reduced osmotic stress during V. parahaemolyticus and WSSV infection.…”

A total of 173 bacterial strains were isolated from different sources at different regions such as fermented foods, shrimp guts, sea water, mangrove water, and sediments. These bacteria were screened against white spot syndrome virus (WSSV) infection in Palaemon paucidens . Based on mortality, white spot level, and healthiness, three bacterial strains were selected and identified using 16S rRNA gene sequencing. These bacterial strains were Bacillus subtilis KA1, B. licheniformis KA2, and B. subtilis KA3. WSSV challenge test in pilot scale was conducted using Litopenaeus vannamei with B. subtilis KA1 and B. subtilis KA3. The survival ratio of shrimp was 0% for WSSV control after 17th days, 84% for B. subtilis KA1 plus WSSV after 26th days, and 28% for B. subtilis KA3 with WSSV after 26th days. B. subtilis KA1 showed good growth at 18–37 °C in with and without 3% NaCl, and therefore can be applied to aquaculture at low to high temperatures. B. subtilis KA1 produced protease and lipase which can increase digestion to shrimp; exhibited antibacterial activity against Vibrio parahaemolyticus ; and significantly increased the survival of WSSV challenged shrimps.

“…White spot syndrome virus and infectious hypodermal and hematopoietic necrosis virus have been responsible for extensive economic losses ( Kuebutornye et al, 2020 ). A number of Bacillus species isolates have been used to enhance the antiviral immunity of crustaceans ( Sánchez-Ortiz et al, 2016 ; Sekar et al, 2016 ; Pham et al, 2017 ; Kuebutornye et al, 2020 ).…”

Probiotics at War Against Viruses: What Is Missing From the Picture?

Our world is now facing a multitude of novel infectious diseases. Bacterial infections are treated with antibiotics, albeit with increasing difficulty as many of the more common causes of infection have now developed broad spectrum antimicrobial resistance. However, there is now an even greater challenge from both old and new viruses capable of causing respiratory, enteric, and urogenital infections. Reports of viruses resistant to frontline therapeutic drugs are steadily increasing and there is an urgent need to develop novel antiviral agents. Although this all makes sense, it seems rather strange that relatively little attention has been given to the antiviral capabilities of probiotics. Over the years, beneficial strains of lactic acid bacteria (LAB) have been successfully used to treat gastrointestinal, oral, and vaginal infections, and some can also effect a reduction in serum cholesterol levels. Some probiotics prevent gastrointestinal dysbiosis and, by doing so, reduce the risk of developing secondary infections. Other probiotics exhibit anti-tumor and immunomodulating properties, and in some studies, antiviral activities have been reported for probiotic bacteria and/or their metabolites. Unfortunately, the mechanistic basis of the observed beneficial effects of probiotics in countering viral infections is sometimes unclear. Interestingly, in COVID-19 patients, a clear decrease has been observed in cell numbers of Lactobacillus and Bifidobacterium spp., both of which are common sources of intestinal probiotics. The present review, specifically motivated by the need to implement effective new counters to SARS-CoV-2, focusses attention on viruses capable of co-infecting humans and other animals and specifically explores the potential of probiotic bacteria and their metabolites to intervene with the process of virus infection. The goal is to help to provide a more informed background for the planning of future probiotic-based antiviral research.
