The present experiment was conducted to study the effect of ethanolic extract of Egyptian propolis given alone or in combination with inactivated Pasteurella multocida vaccine on rabbits challenged with a virulent strain of Pasteurella multocida. Fifty-six New-Zealand rabbits, 6-8 weeks old and non-vaccinated against pasteurellosis, were randomly divided into eight equal groups. The first group...

A therapeutic technology that combines the phototoxic and immune-stimulating ability of photodynamic therapy (PDT) with the widespread effectiveness of the immune system can be very promising to treat metastatic breast cancer. We speculated that the knowledge of molecular mechanisms of existing multi-component therapies could provide clues to aid the discovery of new combinations of an immunost...

Immunostimulants are often use as dietary supplements these can improve the innate defense of animals providing resistance to pathogens during periods high stress, such grading, reproduction, sea transfer and vaccination. The study was conducted determine performance a commonly used immunostimulant, “Betamune” from ACI animal Health Limited on growth Nile Tilapia Oreochromis niloticus. experime...

The control of infectious diseases is a major current challenge in intensive aquaculture. Most commercial vaccines are based on live attenuated or inactivated pathogens that are usually combined with adjuvants, oil emulsions being as the most widely used for vaccination in aquaculture. Although effective, the use of these oil emulsions is plagued with important side effects. Thus, the developme...

The stimulating effect of levamisole on immunity to Corynebacterium pseudotuberculosis in mice was marginal, while no enhancement of immunity could be detected in sheep. The conclusion was reached that, as levamisole has no potentiating effect on immunity to C. pseudotuberculosis in normal sheep, it is of no practical value as an immunostimulant in this instance.

Antigen-specific immunotherapy may offer a unique approach to fight cancer. We have demonstrated that specific immunotherapeutic regimens involving recombinant melanoma antigen family A3 (MAGE-A3) and different immunostimulants exert clinical anticancer activity. In particular, the combination of recombinant MAGE-A3 and AS15, a multicomponent immunostimulant, was found to elicit robust antigen-...
