A phase 2 clinical trial was conducted to evaluate the antibody responses to bovine parainfluenza virus type 3 (bPIV3) vaccination in young infants. Three groups were tested as follows: placebo (n=66) and 10(5) (n=64) or 10(6) (n=62) TCID(50) of bPIV3. The vaccine or placebo was administered intranasally at ages 2, 4, 6, and 12-15 months, and serum specimens were collected at ages 2, 6, 7, 12-1...

Diagnosis of coeliac disease (CD) relies on a combination of clinical, genetic, serological and duodenal morphological findings. The ESPGHAN suggested that biopsy may not be necessary in all cases. New guidelines include omission of biopsy if the concentration of CD-specific antibodies exceeds 10 times the upper limit of normal (10 ULN) and other criteria are met. We analysed the 10 ULN criteri...

Immunoglobulin class-specific antibodies were measured by a solid-phase radioimmunoassay in serum, bronchoalveolar washings (BAW), lung cell lysates, and spleen cell lysates in germfree mice after intranasal (i.n.) and intraperitoneal (i.p.) primary and secondary 10(5), 10(4), and 10(3) mean tissue culture infective doses (TCID(50)) of live parainfluenza 1 (Sendai) virus. The earliest antibody ...

Sera obtained from 34 men with Chlamydia trachomatis positive non-gonococcal urethritis, 34 men with C trachomatis negative non-gonococcal urethritis, 42 women with acute salpingitis, 38 healthy women, and 34 healthy men were studied for the presence of specific serum C trachomatis IgA and IgG antibodies. Serological results were correlated with C trachomatis isolation in cell culture. An enzym...

Formalinized Mycoplasma pulmonis, along with aluminum hydroxide as an adjuvant, was used to subcutaneously immunize rats in the vicinity of the salivary gland to examine the characteristics of the secretory immune response to this pathogen. The induction of specific antibody to this microorganism was detected in serum and the exocrine fluids, namely, saliva and lung lavage fluid. Both immunoglo...

OBJECTIVES To investigate the effect of Chlamydia pneumoniae infection on future development of ischaemic heart disease and mortality. DESIGN Prospective longitudinal study. SETTING Caerphilly, South Wales. SUBJECTS Plasma specimens were collected during 1979-83 from 1773 men aged 45-59 years. These were tested for IgG and IgA antibodies to C pneumoniae (TW183) by microimmunofluorescence....

Aim: To determine the prevalence of celiac disease related autoantibodies in patients with type 1 and 2 diabetes mellitus (DM), and to compare these results with the general population. Methods: In total, 137 consecutive patients with type 1 DM, 172 with type 2 DM and 113 age-sex matched control subjects were included into the study. Antigliadin-autoantibodies (AGA) IgG and IgA, and endomysial-...

OBJECTIVE Increased prevalence of celiac disease (CD) and autoimmune thyroid disorders (ATD) in patients with Type 1 diabetes mellitus (T1D) has been widely reported. Such an association may lead to adverse effects on the growth, bone metabolism and fertility, and response to therapy may become difficult. The aim of this study was to evaluate the clinical findings and HLA typing results in pati...

In the present study, we investigated antibody productions of IgA and other classes, such as IgE and IgG1, in mice as possible evidence of the protective effects of Spirulina toward food allergy and microbial infection. An increase of IgE antibody level in the serum was observed in the mice that were orally immunized with crude shrimp extract as an antigen (Ag group). The antibody level, howeve...

Hypersensitivity to ribitol teichoic acid (RTA), the major antigenic determinant of Staphylococcus aureus, may be important in a rabbit model of corneal phlyctenules and catarrhal infiltrates. Over a 5-month period, an enzyme-linked immunosorbent assay was used to measure immunoglobulin (Ig) G and IgA antibody levels to RTA in sera, tears, and corneas from rabbits immunized using the following ...
