The roles of IgG and secretory IgA in the protection of the respiratory tract (RT) against influenza infection remain unclear. Passive immunization with Ab doses resulting in serum IgG anti-influenza virus Ab titers far in excess of those observed in immune mice has compounded the problem. We compared the effects of i.v. anti-influenza virus IgG and i.v. anti-influenza virus polymeric IgA (pIgA...
Pasteurella multocida subsp. is responsible for different diseases that generate great economic losses in farm animal. The effectiveness of immunization against those bacteria are variable and the use antibiotics questioned; reason, we investigated potential inhibitory effect carbohydrates on adherence vivo P. to rabbit respiratory epithelium as an alternative prevention infections. Rabbits wer...
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...
Vaccination with peptide antigens is an effective strategy against mucosal viral infections. We tested a two-codon mutant of cholera toxin (CT-2*) lacking ADP-ribosylating activity and toxicity as a mucosal adjuvant for T cell epitope peptides for intranasal immunization of mice. Efficient induction of helper and cytotoxic T lymphocyte responses associated with TH1 cytokine production were obse...
The currently available commercial human anthrax vaccine requires multiple injections for efficacy and has side effects due to its alum adjuvant. These factors limit its utility when immunizing exposed populations in emergent situations. We evaluated a novel mucosal adjuvant that consists of a nontoxic, water-in-oil nanoemulsion (NE). This material does not contain a proinflammatory component b...
Studies of immunity to Pseudomonas aeruginosa have indicated that a variety of potential immunogens can elicit protection in animal models, utilizing both antibody- and cell-mediated immune effectors for protection. To attempt to optimize delivery of multiple protective antigens and elicit a broad range of immune effectors, we produced an aroA deletion mutant of the P. aeruginosa serogroup O2/O...
introduction: septal deviation is the chief cause of chronic nasal obstruction. in order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. this study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery. ...
