introduction chicken is the only avian species in which polyclonal antibodies, like igg is transported from the hen to the egg yolk in a similar manner as the transport of mammalian igg from the mother to the fetus. immunoglobulin y in the chicken is transported to the egg and accumulates in the egg yolk in large quantities. igy is an egg yolk antibody that has been used widely for treatment an...

In this study, 90 internal organ samples of poultry with symptoms of colibacillosis were obtained from Maragheh poultry farms in East Azerbaijan, Iran. In total, 70 bacterial isolates were confirmed as Escherichia coli (E. coli) strains using standard biochemical tests, and antibiotic sensitivity was determined by the disk diffusion method. Antibiotics used in this study included ampicillin, pe...

E-Government services operate, by definition, across the Internet: citizens use their own desktops or mobile devices to access, via the Internet, government services hosted on servers physically located in some government agency, or even on a private or public cloud. Attacks on e-government can such be broadly divided into three categories: server-side attacks (i.e. on the government servers), ...

Since 2004, many nations have started issuing “e-passports” containing an RFID tag that, when powered, broadcasts information. It is claimed that these passports are more secure and that our data will be protected from any possible unauthorised attempts to read it. In this paper we show that there is a flaw in one of the passport’s protocols that makes it possible to trace the movements of a pa...

Man in the middle attacks involve the interception and retransmission of electronic messages in a way that the original parties will presume that their communication is secure. Such an attack could be a threat to any electronic voting scenario. This paper proposes a novel method for preventing this kind of attacks by including in the transaction a challenge-response test. The human end-user is ...

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...

Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transfor...
