2. Chicken eggs as a surveillance tool for malaria and leishmaniasis vector presence
Abstract INTRODUCTION: Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector’s saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis. METHODS: We used ELISA to quant

3. Effects of raw propolis or water and ethanol extracts of propolis on performance, immune system, and some blood parameters of broiler breeders
ABSTRACT The objective of this study was to determine the effects of raw bee propolis and water or ethanol extract of propolis on growth performance, some blood parameters, and immunoglobulins in 15-20-week-old Ross-308 broiler breeders. The birds in the control were fed a diet without propolis, whereas the birds in the treatment groups were fed diets with r

4. Gallus gallus domesticus: sistema imunológico e seu potencial para geração de imunobiológicos
RESUMO: O sistema imunológico deGallus gallus domesticus é uma ferramenta promissora para a geração de imunobiológico a partir de anticorpos. A imunoglobulina Y (IgY) é extraída da gema do ovo e apresenta funções equivalentes ao anticorpo IgG dos mamíferos. O sistema imune aviário pode ser estimulado para produzir um repertório de anticorpos de a

5. Frequência de anticorpos anti-Toxocara em frangos de corte no Sul do Brasil
Resumo A finalidade do presente estudo foi avaliar a presença de anticorpos anti- Toxocara, em frangos de corte naturalmente infectados (n = 189), no Norte do Paraná, Sul do Brasil. Os frangos foram criados em sistema semi-intensivo, em pequenas propriedades rurais (n = 7). Os testes sorológicos foram realizados pela técnica de ELISA, para detecção de

6. Preparation and neutralization efficacy of IgY antibodies raised against Deinagkistrodon acutus venom
Abstract Background The five-paced pit viper (Deinagkistrodon acutus), endemic to China and northern Vietnam, is responsible for most snakebites in the Chinese territory. Antivenom produced from horses is the main treatment for snakebites, but it may cause numerous clinical side effects and have other disadvantages involved in their production such as the

8. Influence of eggshell colour on egg yolk antibody level, incubation results, and growth in broiler breeders
ABSTRACT This study was performed to determine the effect of shell colour in eggs acquired from Ross-308 broiler breeders on the interior and exterior quality of the egg, the antibody content of the egg yolk, and growth performance. The shell colours of a total of 1350 eggs were classified, using a colorimeter, into three groups: dark (E<64), medium (E:64.00

9. Anti-Trimeresurus albolabris venom IgY antibodies: preparation, purification and neutralization efficacy
Abstract Background Snakebite incidence in southwestern China is mainly attributed to one of the several venomous snakes found in the country, the white-lipped green pit viper Trimeresurus albolabris. Since antivenom produced from horses may cause numerous clinical side effects, the present study was conducted aiming to develop an alternative antivenom ant

10. Effects of Arginine Supplementation on Organ Development, Egg Quality, Serum Biochemical parameters, and Immune Status of Laying Hens
Abstract This experiment was conducted to study the effects of arginine supplementation on organ development, egg quality, blood parameters, and immune status of laying hens. A total of 360 25-week-old brown Leghorn laying hens were randomly divided into three groups with six replicates of 20 birds each and fed diets supplemented with 0, 8.5, or 17 mg of L-a

11. Using immunoglobulin Y as an alternative antibody for the detection of hepatitis A virus in frozen liver sections
An increasing amount of research has been conducted on immunoglobulin Y (IgY) because the use of IgY offers several advantages with respect to diagnostic testing, including its easy accessibility, low cost and translatability to large-scale production, in addition to the fact that it can be ethically produced. In a previous work, immunoglobulin was produced

12. Production and Characterization of IgY against Canine IgG: Prospect of a New Tool for the Immunodiagnostic of Canine Diseases
This study describes the production of a new avian polyclonal antibody (IgY) against canine IgG, as another tool for the immunodiagnostic using IgY technology. The immunization protocol caused neither deaths nor pathologies, and no decline in egg laying capacity was detected. The total concentration of isolated IgY was constant, without significant differenc
