The poultry industry in Vietnam is vulnerable to many viral diseases. Since antibiotics and vaccination provide inadequate protection, it will be beneficial to have alternative immunostimulants to boost non-specific immunity in poultry. Chicken interferon-alpha (ChIFNα) has been described previously with antiviral activity against many pathogens.

The exopolymer (EPSp) produced by the strain B. licheniformis IDN-EC was isolated and characterized using different techniques (MALDI-TOF, NMR, ATR-FTIR, TGA, DSC, SEM). The results showed that the low molecular weight EPSp contained a long polyglutamic acid and an extracellular teichoic acid polysaccharide.

Pseudorabies virus (PRV), a member of the Alphaherpesviruses, is one of the most important pathogens that harm the global pig industry. Accumulated evidence indicated that PRV could infect humans under certain circumstances, inducing severe clinical symptoms such as acute human encephalitis.

MTT assay was implemented in order to calculate the sample toxicity levels on cell culture. Our data suggest that Greek bee bread and bee collected pollen exhibit potent antiviral activity against EV-D68 with IC50 values ranging from 0.048 to 5.45 mg/ml. Greek bee bread and bee collected pollen are promising sources of antiviral compounds and should be further studied against diverse viruses in order to explore their full antiviral potential.

Cryptocaryon irritans is an obligate parasitic ciliate protozoan that can infect various commercially important mariculture fish species and cause high lethality and economic loss. Current methods of controlling this parasite with chemicals or antibiotics are widely considered to be environmentally harmful. Piscidins with broad spectrum antibacterial, antifungal and antiviral activities were found to have potent activity against C. irritans. Little, however, has been understood about the killing mechanisms of piscidins in parasites.

The selectivity index of these compounds is similar to that of cidofovir. Although antiviral activity was evident in secondary assays, significant virus inhibition occurred at or near the cytotoxic concentration (SI90=1).

Viral diseases are one of the major factors threatening crop production worldwide. It is estimated that about 15 percent of global crop production is lost due to various plant diseases, and phytopathogenic viruses are thought to cause more than one third of plant diseases. Viruses such as TYLCV, PRSV, CMV, BBTV are some major virus epidemics which cause heavy losses in horticultural crops. Management of plant virus diseases have acquired great importance in the realm of Plant Pathology and call for effective management against them.

Mushroom fungi secrete antifungal, antibacterial and antiviral bioactive compounds of therapeutic and pharmacological value. Very limited work has been done on the exploration of antimicrobial principles from macrobasidiomycetes against plant pathogens. In this view, a study was proposed to screen eight mushroom fungi viz.

Mastitis is one of the major factors obstructing the progress of the dairy industry. The use of antibiotics has been related with antibiotic-resistant pathogens. Consequently, several studies have been done in order to find natural alternatives. One of these alternatives is propolis which has been identified as an appropriate option according to recent studies of antibacterial, antiviral, antifungal, and antiprotozoal activity.

Egypt has the highest prevalence of hepatitis C virus (HCV) worldwide. Currently, combined pegylated interferon and ribavirin therapy are the standard treatment. The biological activity of interferon (IFN) is mediated by the induction of intracellular antiviral proteins, such as 20 –50 oligoadenylate synthetase, and dsRNA-activated protein kinase. IFN-inducible doublestranded RNA-activated protein kinase (PKR) is thought to play a key antiviral role against HCV. Some studies observed that PKR expression was higher in sustained viral responders compared with the non-responders.

Extracts from respective parts and cell cultures of some Turkish medicinal plants have been assessed for their antiviral and cytotoxic properties. None of the extracts tested showed notable activity against herpes simplex viruses (HSV-I and II), but a slight antiretroviral activity against HIV-I was determined in an extract from Hypericum capitatum cell cultures.

The present study evaluated the in vitro antimicrobial, antioxidant, and antiviral activities of the essential oil and various extracts of Salvia limbata C.A.Mey. and Salvia sclarea L., as well as the content of its essential oil. The activities of essential oils were tested against a wide range of human-, plant-, and food-borne microorganisms.

In the current study, the oils obtained from the nuts of Corylus avellana L. (hazelnut), Arachis hypogea L. (peanut, groundnut), Pinus pinea L. (umbrella nut), and Juglans regia L. (walnut) were tested for their antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and antimicrobial activity against the standard and isolated strains of Escherichia coli, Pseudomonas aeruginosa.

Lactoferrin (Lf), a multifunctional molecule present in mammalian secretions and blood, plays important roles in host defense and cancer. Indeed, Lf has been reported to inhibit the proliferation of cancerous mammary gland epi-thelial cells and manifest a potent antiviral activity against human immunodeficiency virus and human cytomegalo-virus. The Lf-binding sites on the cell surface appear to be proteoglycans and other as yet undefined protein(s).

In a previous study, severe acute respiratory syndrome coronavirus (SARS-CoV) was cultured in the presence of bananin, an effective adamantane-related molecule with antiviral activity. In the present study, we show that all bananin-resistant variants exhibit mutations in helicase and membrane protein, although no evidence of bananin interference on their mutual interaction has been found.

Economic conditions, frustration with high cost levels and limited success in encouraging employees to adopt healthier lifestyles have been persistent challenges for companies. Against the backdrop of health care reform, companies have never been more uncertain about the future of their health care programs over the long term. For nearly a decade, Towers Watson has been tracking employers’ coni dence in their ability to sponsor health care benei ts for active employees 10 years into the future.
