BACKGROUND: BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is the main causative agents of neonatal calf diarrhea. Passive transfer of antibodies that is derived from the dams of the calves through their colostrum plays an important role in disease prevention. OBJECTIVES: To determine the presence of natural specific antibodies against K99 antigen in dam’s serum and colostrum as well as in...

Background: Immunopathological and inflammatory processes play important roles in the initiation and development of Ischemic Heart Disease (IHD). Objective: The aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (RF), anti-nuclear antibodies (ANA), anti-small nuclear ribonucleoprotein (anti-Sm), anti-phosphatidylserine (anti-PS) and anti-car...

the measurement of anti-streptokinase antibodies can distinguish the patients who may benefit from streptokinase and those who should be treated with some other thrombolytic regimen. neutralising titration test is a commonly used classical assay for measuring anti-streptokinase antibodies and in this assay the ability of anti-streptokinase antibodies in patients' sera in preventing the lytic ef...

Passively acquired antibodies through colostrum will protect calves against etiological agents of neonatal calf diarrhea. Among them enteric diseases due to strains of Enterotoxigenic Escherichia coli (ETEC) are the most commonly occurring form of colibacillosis in newborn calves. Specific antibodies against whole ETEC cells and total immunoglobulin G in dam serum, colostrum and calf serum were...

background: immunopathological and inflammatory processes play important roles in the initiation and development of ischemic heart disease (ihd). objective: the aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (rf), anti-nuclear antibodies (ana), anti-small nuclear ribonucleoprotein (anti-sm), anti-phosphatidylserine (anti-ps) and anti-car...

background: infertility is one of the common problems seen in couples of reproductive age. presence of antisperm antibodies in semen and serum are amongst the causes of immunoinfertility. this study was performed to determine antisperm antibodies in cervicovaginal secretions and serum of infertile women and also measure serum levels of immunoglobulins (igg, igm and iga). methods: the study cons...

objective: the purpose of the study was to evaluate the production of antibodies in serum as well as egg yolk raised against s. typhimurium and the cross-reactivity of this antibody with other enteric bacteria. materials and methods: white egg–laying hens were immunized with s. typhimurium, heat-killed whole cell, in freund's adjuvant. immunization was done with 107 conlony forming unit (cfu) o...

background: due to underlying autoimmune background of guillain-barré syndrome (gbs), the possible role of infectious agents cytomegalovirus  (cmv) and  epstein-barr virus (ebv) and also due to association  of anti-ganglioside antibodies with gbs, the present study aimed to investigate the  associations   between serum anti-ganglioside antibodies (aga) level,  type  of  infection  and electrodi...
