Evaluation of a bi-epitope of glyceraldehyde 3-phosphate dehydrogenase and Disorganized Muscle in the protection of sheep against Haemonchus contortus
Descripción del Articulo
The aim of this study was to evaluate the protection capacity in sheep against Haemonchus contortus using a peptide that mimics epitopes of glyceraldehyde 3- phosphate dehydrogenase (GAPDH) and the Disorganized Muscle (DIM-1) of H. contortus. A genotypic phage library (7 aa-GGG) was evaluated with t...

Evaluation of a bi-epitope of glyceraldehyde 3-phosphate dehydrogenase and Disorganized Muscle in the protection of sheep against Haemonchus contortusEvaluación de un bi-epítopo de gliceraldehídmo 3-fosfato deshidrogenasa y de Desorganización Muscular en la protección de ovinos contra Haemonchus contortusDíaz, ArnielisGarcía, YipsiSánchez, YulietBuzatti, AndreiaRodríguez, YanexisInfante, MaritzaTorres, UbaldoArenal, AmilcarMolento, MarceloDIM-1GAPDHphage librarypeptidesmultiepitopesDIM-1GAPDHbiblioteca de fagospéptidosmultiepítoposThe aim of this study was to evaluate the protection capacity in sheep against Haemonchus contortus using a peptide that mimics epitopes of glyceraldehyde 3- phosphate dehydrogenase (GAPDH) and the Disorganized Muscle (DIM-1) of H. contortus. A genotypic phage library (7 aa-GGG) was evaluated with the use of a polyclonal anti-H. contortus antibody IgG. After three rounds of selection, 120 clones were sequenced and the amino acid sequences were aligned. Peptide sequences similar to DIM-1 and GAPDH were selected, and a peptide with these two epitopes was synthesized. A group of four rams with the bi-epitope and another similar group with the adjuvant were immunized on days 0, 7, 14 and 28. One week after the last vaccination all the animals were challenged with 1250 L3 larvae of H. contortus. The average number of eggs per gram of feces (hpg) and the parasitic load in the abomasum of the group vaccinated 70 days after the infestation were reduced by 57.9 and 52.7%, respectively. Serum IgG levels were significantly higher in the vaccinated group; it also increased the number of eosinophils and increased the hemoglobin.El objetivo del estudio fue evaluar la capacidad de protección en ovinos contra Haemonchus contortus de un péptido que mimifica epítopos de gliceraldehído 3-fosfato deshidrogenasa (GAPDH) y Desorganización Muscular (DIM-1) de H. contortus. Se hizo una búsqueda en una biblioteca de fagos (7 aa-GGG) con el empleo de un anticuerpo policlonal (IgG) anti-H. contortus. Después de tres rondas de selección se secuenciaron 120 clones y se hizo el análisis de secuencia de cada clon. Se seleccionaron clones cuya secuencia de péptidos fue similar a la proteína de DIM-1 y a la GAPDH, y se sintetizó un péptido con estos dos epítopos. Los animales se inmunizaron los días 0, 7, 14 y 28. Una semana después de la última vacunación todos los animales se desafiaron con 1250 L3 de H. contortus. La media de huevos por gramo de heces (hpg) y la carga parasitaria en el abomaso del grupo vacunado a los 70 días de la infestación se redujeron en 57.9 y 52.7%, respectivamente. Los niveles de IgG en suero fueron significativamente más altos en el grupo vacunado; además aumentó el número de eosinófilos y subió el valor de la hemoglobina.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2018-11-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/1530410.15381/rivep.v29i4.15304Revista de Investigaciones Veterinarias del Perú; Vol 29 No 4 (2018); 1391-1402Revista de Investigaciones Veterinarias del Perú; Vol. 29 Núm. 4 (2018); 1391-14021682-34191609-9117reponame:Revista UNMSM - Revista de Investigaciones Veterinarias del Perúinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/15304/13311https://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/15304/13834Derechos de autor 2018 Arnielis Díaz, Yipsi García, Yuliet Sánchez, Andreia Buzatti, Yanexis Rodríguez, Maritza Infante, Ubaldo Torres, Amilcar Arenal, Marcelo Molentohttp://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2021-06-01T18:09:34Zmail@mail.com - |
