background and aims. despite available evidence for the role of herpes viruses in destructive periodontal diseases, no cause-and-effect relationship has been found to date. this study compared the titer of immunoglobulin g (igg), immunoglobulin m (igm) against human cytomegalovirus (hcmv) in gingival crevicular fluid between individuals with periodontitis and with healthy periodontium. material...

BACKGROUND Newcastle disease (ND) is a highly infectious disease causing considerable economic losses to poultry farmers worldwide. Conventional vaccine delivery methods are not suitable for smallholder and rural poultry producers, and thus appropriate vaccination methods need to be sought. This study was carried out with the main objective of evaluating the efficacy of ND I2 vaccine delivered ...

the serious influenza-associated complications among immunodeficient individuals such as those who are infected with human immunodeficiency virus (hiv), highlights the importance of influenza vaccination in these people. therefore, the current study aimed to investigate the antibody responses to influenza vaccine in this group. two hundred subjects were recruited, during autumn 2010 and 2011, t...

toxoplasmosis is a wide distributed opportunistic infection caused by toxoplasma gondii. this was a cross-sectional study of t. gondii antibody titer, which was conducted from june 2003 to august 2004 on renal transplant recipients in iran. a total of 551 serum samples were obtained from randomly selected population referred from different areas all over the country to shafa central clinic in t...

objective: this study aimed to assess the value of chlamydia trachomatis (c.trachomatis) antibodytiter test in prediction of  tubal damage. materials and methods : in this case-control study we enrolled50 women with tubal factor infertility (proven by laparoscopy after hysterosalpingography) and 110 women without infertility history. elisa was performed for all participants, seeking c.trachomat...

Of 20 strains of virus recovered from 40 patients with poliomyelitis only 9 possessed a titer of 10(-3) or more, permitting significant quantitative neutralization tests in monkeys. Seven of the 9 high titer strains were derived from patients whose illness was ultimately paralytic, and tests with their undiluted sera indicated that the acute phase as well as the 3 month convalescent specimens n...

background: systemic lupus erythematosus (sle) is a chronic autoimmune disease which is characterized by b-cell abnormality and auto-antibody generation. since bacterial infections are the most important causes of mortality in these patients, pneumococcal vaccination is recommended for children with sle. objective: to investigate humoral immunity and specific-antibody formation in response to a...

Influenza virus hemagglutinin (HA) surface glycoprotein is currently the primary target of licensed influenza vaccines. Recently, broadly reactive antibodies that target the stalk region of the HA have become a major focus of current novel vaccine development. These antibodies have been observed in humans after natural infection with influenza A virus, but the data are limited. Using samples an...
