BACKGROUND BCG, the only licensed vaccine against tuberculosis, provides some protection against disseminated disease in infants but has little effect on prevention of adult pulmonary disease. Newer parenteral immunization prime boost regimes may provide improved protection in experimental animal models but are unproven in man so that there remains a need for new and improved immunization strat...
Pediatric tuberculosis (TB) is an underappreciated problem and accounts for 10 % of all TB deaths worldwide. Children are highly susceptible to infection with Mycobacterium tuberculosis and interrupting TB spread would require the development of effective strategies to control TB transmission in pediatric populations. The current vaccine for TB, M. bovis Bacille Calmette-Guérin (BCG), can affor...
The lack of validated immunological correlates of protection makes tuberculosis vaccine development difficult and expensive. Using intradermal bacille Calmette-Guréin (BCG) as a surrogate for aerosol Mycobacterium tuberculosis (M.tb) in a controlled human infection model could facilitate vaccine development, but such a model requires preclinical validation. Non-human primates (NHPs) may provide...
Background: Salmonella, a bacterial genus of more than 2500 serotypes is considered as the most significant foodborne pathogen causing infections in humans and animals. Increased antimicrobial resistance and persistence of antimicrobial residues in food matrices warrants the need for alternative infection management strategies. Aims: The present study aimed to isolate and evaluate the lytic act...
Immunogenicity of a low-virulence vaccinal strain against Salmonella abortus-ovis infection in mice.
Strain Rv6, a streptomycin-independent reverse mutant of Salmonella abortus-ovis, multiplied and disseminated in vivo to a lesser extent than the virulent parental strain 15/5, as determined by subcutaneous inoculation of two outbred strains of mice with different susceptibilities to salmonella infection. This lower virulence of strain Rv6 was not modified by 10 passages in susceptible mice. Va...
PURPOSE Bacillus Calmette-Guérin (BCG) vaccine has widely been used to immunize against tuberculosis, but its protective efficacy is variable in adult pulmonary tuberculosis, while it is not efficiently protective against progressive infection of virulent Mycobacterium tuberculosis strains. In this study, the protective effects of plasmid DNA vaccine constructs encoding IL-12 or IL-18 with the ...
Bacille Calmette-Guérin (BCG), an attenuated strain of Mycobacterium bovis, is the only vaccine available for tuberculosis (TB) control. However, BCG is not an ideal vaccine and has two major limitations: BCG exhibits highly variable effectiveness against the development of TB both in pediatric and adult populations and can cause disseminated BCG disease in immunocompromised individuals. BCG co...
Acute disseminated encephalomyelitis (ADEM) is a monophasic clinical syndrome, characterized by immune-mediated demyelination of central nervous system neurons, which yield extensive damage in the brain and spinal cord.It usually affects children and young adults following infections or immunization. Here we describe a 9- year-old Fars female presented with acute onset of psychotic disorder, o...
