Previous studies on a limited number of birds suggested that the IgD-encoding gene was absent in birds. However, one of our recent studies showed that the gene was definitely expressed in the ostrich and emu. Interestingly, we also identified subclass diversification of IgM and IgY in these two birds. To better understand immunoglobulin genes in birds, in this study, we analyzed the immunoglobu...

Sentul chicken is one of Indonesia’s native chickens that has high potential for meat and egg production performance. The breeds with body resistance the solutions to fulfill this potential. This research aimed ascertain impact various IgY concentrations (high, medium, low) on 90 Debu Kelabu chickens. Parameters observed included pre-laying laying Six replications a completely randomized design...
Rheumatoid factor (RF) is a major source of interference in many immunoassays. Most immunoassays use mammalian polyclonal or monoclonal antibodies, and RF can react with IgG from mammalian species, thus causing false-positive results. In this work we have studied RF interference in a sandwich ELISA, where RF in the sample may react with both the capture antibody and the detection antibody to gi...
The rapid outbreak of the highly pathogenic H5N1 avian influenza virus and its transmission to humans have induced world-wide fears of a new influenza pandemic. The most effective method for the reduction of the impact of such a pandemic would be prophylaxis with a safe and effective vaccine, as well as anti-viral materials. In this study, we generated the specific antibodies 'immunoglobulin yo...
Mammalian IgG and IgE are thought to have evolved from IgY of nonmammalian tetrapods; however, no diversification of IgY subclasses has been reported in reptiles or birds, which are phylogenetically close to mammals. To our knowledge, we report the first evidence of the presence of multiple IgY-encoding (υ) genes in snakes. Two υ genes were identified in the snake Elaphe taeniura, and three υ g...
In this study, a method for expressing Cryptosporidium hominis GP60 glycoprotein in Escherichia coli for production of polyclonal anti-GP60 IgY in chickens was developed aiming future studies concerning the diagnosis, prevention and treatment of cryptosporidiosis. The full-length nucleotide sequence of the C. hominis gp60 gene was codon-optimized for expression in E. coli and was synthesized in...
In order to improve the sensitivity of proteomic analysis, our group has developed a chicken antibody based column that has successfully depleted high abundance proteins (HAPs) from human plasma prior to mass spectrometry analysis. The use of chicken as a host for polyclonal antibodies production conveys many advantages, including but not limited to, the capabilities of producing large quantiti...
هلیکوباکتر پیلوری یک باکتری گرم منفی اسپیرال و میکروآئروفیل است که در لایه مخاطی معده انسان تکثیر یافته و ایجاد عفونت می نماید. عفونت ایجاد شده توسط این باکتری که با تخریب بافت پوششی معده همراه است، منجر به التهاب مزمن معده می گردد که می تواند سبب ایجاد زخم های معده و دوازدهه گردد. مشکلات ناشی از درمان با آنتی بیوتیک ها باعث شده است که محققین رویکردهای جدیدی برای درمان عفونت های ناشی از h.pylor...
Alternatives to antibiotics for the treatment and prevention of infections are badly needed. Passive immune therapy with avian antibodies (immune globulin, IgY) from eggs of hens, that have been vaccinated with a specific microbe, is a real alternative.
