Tuberculosis (TB) remains a global pandemic despite the use of Bacillus Calmette-Guérin (BCG) vaccine, partly because BCG fails to effectively control adult pulmonary TB. The introduction of novel boost vaccines such as the human Adenovirus 5-vectored AdHu5Ag85A could improve and prolong the protective immunity of BCG immunization. Age at which BCG immunization is implemented varies greatly wor...

introduction: antifertility effects of naturally occuring antisperm antibody (asa) in infertile couples and studies on experimental immunization of various animals with sperm antigens represent asa as an immunocontraceptive target. the effects of different factors on sperm immunogenecity and asa production have been studied and different results have been reported. in this study, whole sperm im...

Three outcomes pertinent to contact sensitivity (CS) follow immunization with various forms of trinitrophenylated (TNP) substrates: (a) specific immunological unresponsiveness for CS is induced when immunization favors activation of splenic suppressor cells. This state is achieved by intravenous injection of trinitrophenyl-conjugated to various types of cells, such as peritoneal exudate cells (...

The feasibility of inducing rheumatic myocarditis lesions in Lewis rats by immunization with formalin-killed group A Streptococcus was evaluated. The rats were divided into three groups. Group A was immunized by injecting formalin-killed group A Streptococcus suspended in complete Freund's adjuvant (CFA) into the hind-foot pads and repeat immunization was given 1 week later by subcutaneous inje...

Experimental Autoimmune Encephalomyelitis (EAE) can be induced in mice of the C57BL/6 strain by subcutaneous immunization with myelin/oligodendrocyte glycoprotein (MOG) peptide p35-55 in CFA, administered twice at an interval of one week and supplemented with Bordetella pertussis toxin given IV. Here, we studied the effect on the induction of EAE of depleting antibodies to CD4, CD8, or CD25 adm...

A multi-dose injector to facilitate the immunization of horse by the ‘low dose, low volume multi-site’ protocol in antivenom/antitoxin production is described. With the device, 20 subcutaneous injections of about 0.1 ml of CFA emulsified immunogen around the horse’s neck could be easily accomplished within 3 minutes without any stress to the animal. Also described is an apron to prevent blister...

1. Intravenous injection into mice of phase I Bordetella pertussis vaccine resulted in a striking hyperleucocytosis with a predominating lymphocytosis. Intraperitoneal inoculation was less effective, and subcutaneous administration was inactive. 2. Active immunization prevented the hyperleucocytosis; passive immunization was less effective. 3. Reticuloendothelial blockage reduced the effect of ...

The antibody response patterns of cattle after subcutaneous and intranasal immunizations with adhesin Tf190 of Tritrichomonas foetus were investigated. Reactions of antibody from cattle parenterally immunized with Tf190 revealed antigen specificity and Tf190 sensitization in the majority of the animals, as determined by Western blotting. The results also demonstrated strong preimmune immunoglob...

This study examined the role of intranasal vaccination with Mycobacterium tuberculosis antigen85 complex proteins formulated in dimethyldioctadecylammonium bromide against airway Mycobacterium tuberculosis challenge in mice. Intranasal vaccination with antigen85A and antigen85B induced a significantly higher level of interferon-gamma, interleukin-12 and interleukin-4 in cervical lymph nodes tog...
