Lactococcosis disease incident caused by Lactococcus garvieae has been increased with increasing aquaculture productions and outbreaks of the disease have become a threat on farmed species. To prevent lactococcosis, inactivated vaccine has been used, however, it only provides protection when given by injection. Other than inactivated vaccine, various vaccines such as subunit vaccines c...

Objective(s): Despite treatment with antibiotics and vaccination with BCG, tuberculosis (TB) is still considered as one of the most important public health problems in the world. Therefore, designing and producing a more effective vaccine against TB seems urgently. In this study, immunogenicity of a fusion protein which consisting or comprising CFP-10 from Mycobacterium tuberculosis and the Fc-...

Bovine theileriosis is a tick-borne disease caused by obligate intracellular parasites related to the genus Theileria. Cellular immune responses protect cattle against pathogens through the activation of immune cells. Nowadays, live, attenuated vaccine of Theileria annulata (T. annulata) is being produced in Iran and is recommended for active cattle immunization. Detection of the immunogenic  a...

background: herpes simplex virus type 2 (hsv-2) is highly prevalent and major cause of genital herpes in humans. the life-long nature of infection and the increasing prevalence of genital herpes imply that vaccination is the best strategy for controlling the spread of infection and limiting hsv disease. hsv glycoprotein d (gd) is one of the most important viral immunogen which has an essential ...

objectives: enterotoxigenic escherichia coli (etec) is one of the most common agents of diarrhea among other bacterial agents. designing and producing vaccine against these bacteria is one of the major purposes of world health organization (who). due to presence of diverse clones of etec strains in the world, the use of global vaccines for etec infection is controversial. b subunit of heat labi...

Recent studies have demonstrated the effectiveness of vaccine delivery to the skin by vaccine-coated microneedles; however there is little information on the effects of adjuvants using this approach for vaccination. Here we investigate the use of TLR ligands as adjuvants with skin-based delivery of influenza subunit vaccine. BALB/c mice received 1 µg of monovalent H1N1 subunit vaccine alone or ...

Subunit influenza vaccines have the advantage of purity and a broad dosage range. Clinical studies were done with a new subunit vaccine produced by detergent fractionation with tri-(n-butyl) phosphate (TNBP). Acceptability by the recipients was compared in volunteers given 400 CCA units of A2 and 300 of B Influenza vaccine as either Sharples, zonal centrifuged, ether subunit, or TNBP subunit bi...

vaccination has greatly improved human health. despite of all improvements in this field, there is not an efficient vaccine for many diseases, and of the available ones, some could not produce a long-term immunity. recently, there have been many researches on the applicability of nanostructures as an efficient system for vaccine delivery, and the initial results have been promising. their poten...

Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...
