The purpose of the present study was to compare serum and mucosal immune responses following either aerosol (Aer) or subcutaneous (SQ) measles immunization of Mexican school children. A cohort of 49 children from 6 to 7 years of age received either Aer ( n = 22) or SQ ( n = 27) Edmonston-Zagreb (EZ) measles vaccine. Serum and nasal secretions were collected(More)
A distinct age-dependent susceptibility to group B streptococcus type III (GBS) was demonstrated, utilizing a neonatal rat model. The most dramatic changes in susceptibility occurred within the first 7 days of postnatal life. To further investigate this susceptibility, experiments were performed utilizing two age groups of rats: (i) animals within the first(More)
We developed a new experimental model of accelerated diabetes mellitus in the genetically susceptible diabetes-prone BB rat with the administration of the IFN-alpha inducer poly I:C. With this model, there was both an increased incidence and accelerated onset of insulin-dependent-diabetes in poly I:C-treated animals compared with saline-treated controls.(More)
Rabbit alveolar macrophages (AM's) were collected by tracheobronchial lavege at sequential times during animal development. The total number of cells recovered by this technique was found to increase markedly shortly before birth (Fig. 4). This apparent influx of macrophages into the alveoli continued during the first postnatal week, and, at a reduced rate,(More)
The association of in vitro human leukocytes with pilated, type 2 Neisseria gonorrhoeae exceeds that for nonpilated, type 4 organisms but is less than that for nonpilated, type 4(*) gonococci. The two nonpilated forms of gonococci (types 4 and 4(*)) attach to tissue culture cells to a much lesser extent than do pilated, type 2 organisms of the same strain.(More)
The changes in pulmonary cell population in response to aerosols containing either Pseudomonas aeruginosa or Staphylococcus aureus were studied in a murine model. The lungs of inbred DBA/2J mice received an inoculum of 2 X 10(5) colony-forming units of the microorganism and lung lavages were performed at various time intervals thereafter. P. aeruginosa(More)
Although the administration of a fixed dose of the alpha-interferon (alpha-IFN) inducer, polyinosinic polycytidilic acid (poly I:C), accelerates the development of diabetes in DP-BB rats, no reports have characterized the dose-response relationship of poly I:C with serum alpha-IFN levels and the development of diabetes. This study examines the dose-response(More)
Diagnosis of tuberculosis (TB) in children by the tuberculin skin test (TST) poses a diagnostic challenge for physicians due to its low specificity and cross-reactivity with nontuberculous mycobacteria and bacille Calmette-Guerin (BCG). Although interferon-gamma release assays (IGRAs) have been shown as novel TST alternatives for diagnosis of latent TB(More)
