Received: Revised: Accepted: Published online: October 20, 2014 August 18, 2015 September 01, 2015 December 31, 2015 To inactivate locally isolated Mycoplasma gallisepticum (MG), phenol, formaldehyde and binary ethylenimine were optimized for their concentrations and exposure time. Their effect on immunoprophylaxis induction was then assessed by using different levels of immunogen/PCV and diffe...

Newcastle disease (ND) is one of the most important diseases that affect birds; the epizootic nature of the disease has caused severe economic losses in the poultry industry worldwide. In this experiment ND virus (NDV) was inactivated by two different chemicals binary ethylenimine (BEI) and formaldehyde. Formaldehyde was used at 0.1%, while BEI was used at concentrations of 1 to 4 mM. NDV inact...

Abstract There are several vaccines developed against COVID-19 infection. Inactivated viral usually well tolerated. We aimed to present a relapsing immune thrombocytopenia case following inactive vaccine. Here we report of inactivated vaccine in 60-year-old woman with history thrombocytopenia. The patient responded dexamethasone treatment and was discharged from the hospital full recovery. sugg...

We have measured the short-time and long-time elastic responses to compression of various types of surfactant layers adsorbed at oil-water interfaces. We prepared reasonably monodisperse oil-in-water emulsions with the same surfactants and monitored the time evolution of the emulsion droplets' diameter. We used a broad variety of surfactants (cationic, nonionic, and small polymers) and alkanes ...

Water-in-oil emulsions are commonly used to provide persistent release of antigens necessary for sustained stimulation of the immune system. Optimal response of an animal's immune system is dependent upon repeated, maintained exposure to the antigen. The sustained release of antigen, which delays catab-olism, is thought to be one of the major methods by which adjuvants enhance the immune respon...

The resistance of cattle with varying serum-antitoxin titres was determined by per os challenge. The results proved that a solid immunity can be produced against C. botulinum toxins C1 and D. The immune response of cattle to various quantities of C. botulinum C1 and D toxoids, aluminium-phosphate-adsorbed and in water-in-oil emulsion was investigated. The response to antigen in water-in-oil emu...

Microencapsulation of flavors is the technology of converting liquid flavor materials into easy-to-handle solids. It also provides protection against degradation reactions and prevents the loss of volatiles compounds. The capsule wall material along with the emulsion properties (i.e. viscosity and droplets size) and the drying process conditions are some of the responsible factors for the flavo...

the oil refining industries are using a number of demulsifiers for dewatering and desalination of crude oil but experience has shown that universal demulsifiers can not be produced. each kind of water in oil (w/o) emulsion requires specific by composition demulsifier. in practice, synergetic effect of the interaction between different types of demulsifiers is often sought. for dewatering the w...

foot and mouth disease (fmd) is the most contagious disease of cloven-hoofed animals, causingsignificant economical losses in livestock animals. in this study fmd virus type a87/irn was cultured andmultiplied on bhk21 cells. the fmd virus was titrated by the tissue culture infection dose50 method(tcid50 /ml), the virus titration was 107.5.. the fmd virus samples were irradiated and inactivated ...

an adjuvant is a substance that is added to a vaccine to increase the body's immune response to the vaccine. vaccines containing adjuvants are tested for safety in clinical trials before they are licensed for used. the basic action of adjuvants is stimulating adaptive immune responses. adjuvants, recently licensed for human utlization, involve alum squalane oil or water emulsion, influenza viro...
