A simple and economic three-step process for producing highly purified Fab’ fragments directly from the egg yolk water-soluble fraction
(Elsevier, 2022-11)Although mammals are still the main source of polyclonal antibodies production, the use of egg yolk immunoglobulins (IgY) is increasing, and thus improvement of its safety to reduce undesired reactions is needed. Removal ... -
Brucella spp. Lumazine synthase as a novel immunomodulator to produce egg yolk antibodies
(Scientific Research, 2012-02)Lumazine synthase from Brucella spp. (BLS) is a highly immunogenic decameric protein. It has been previously described as a carrier of peptides or proteins to increase their immunogenicity in different animal species, but ... -
Chicken egg yolk antibodies against bovine respiratory syncytial virus neutralize the virus in vitro
(Elsevier, 2012)Bovine respiratory syncytial virus (BRSV) and its counterpart in humans (HRSV) are two closely related virus, which are the leading cause of severe respiratory syndrome in calves and young children, respectively. Passive ... -
Effect of maternal environment on yolk immunoreactive corticosterone and its influence on adrenocortical and behavioral activity in chicks of Greater Rhea (Rhea americana)
(Elsevier, 2019-08)Maternal corticosterone in avian eggs may modify offspring phenotype in order to increase survival in poor environments. In the Greater Rhea (Rhea americana), we previously found that yolk immunoreactive corticosterone is ... -
IgY against enterotoxigenic Escherichia coli administered by hydrogel-carbon nanotubes composites to prevent neonatal diarrhoea in experimentally challenged piglets
(2016-06-14)In previous studies, the applicability of polymeric hydrogels for the protection of egg yolk immunoglobulin (IgY) against simulated gastric conditions was established. Thereafter, the performance of the hydrogels was ... -
IgY-based antivenom against Bothrops alternatus: Production and neutralization efficacy
(Elsevier, 2019-05)Antivenom for the treatment of bothropic snakebite is a priority for public health institutions from Latin America. An alternative to the conventional antivenom production is based on the use of egg yolk antibodies – ... -
IgY-technology (egg yolk antibodies) in human medicine: a review of patents and clinical trials
(Elsevier, 2020-04)IgY-technology (the production and extraction of specific IgY antibodies from egg yolk) is an innovative method to produce antibodies for therapy and prophylaxis. Advantages of IgY over other antibodies comprise its ... -
In vitro inhibitory activity of IgY antibodies against Salmonella ser. newport isolated from horses
(Elsevier, 2021-08)Equine salmonellosis is caused by several Salmonella serotypes, including Salmonella Newport, which cause enterocolitis and diarrhea. Treatment usually includes the administration of antibiotics. However, since multidrug-resistant ... -
In vivo neutralization of bee venom lethality by IgY antibodies
(Elsevier, 2021-07)Bee venom is a complex mixture of molecules, among which melittin and phospholipase A2 (PLA2) are the toxic components involved in envenoming accidents with multiple honeybee stings. Traditionally, the treatment of envenomings ... -
Relación yema: albumen en huevos de tres genotipos de gallinas ponedoras destinadas a sistemas semi intensivos
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2022-08-06)Se estudió el comportamiento dinámico de la relación yema:albumen en huevos del cruzamiento de tres vías Campero Casilda en comparación con Negra INTA y Rhode Island Red. Se trabajó con muestras aleatorias de 15 huevos de ... -
Use of adjuvant ISA VG 71 to produce neutralizing egg yolk antibodies against bothropic venom
(Springer, 2023-02)The use of egg yolk antibodies—IgY technology—represents an alternative to the production of mammalian immunoglobulins and has several advantages regarding animal welfare and lower costs of production. The use of adjuvants ... -
Yolk corticosterone and progesterone levels in Greater Rhea (Rhea americana) eggs vary in a changing social environment
(Wiley, 2022-07)Maternal hormones in avian egg yolks may signal and prepare offspring for the prevailing conditions. However, this adjustment requires some degree of flexibility in regulating yolk hormone deposition. The Greater Rhea (Rhea ...
