(1) Background: The emergence of H5N1 Influenza A viruses clade 2.3.3.4b since 2020, have caused the mortality thousands birds/mammals worldwide, through evolu-tionary changes been associated with acquired mutations and posttranslational modifications. (2) Methods: This study aimed to compare mutational profile avian virus isolated from a Peruvian natural reserve, recent data other related international studies made in human different species domestic wild birds mammals. Briefly, near...
En el presente trabajo se reporta la presencia de Plesiomonas shigelloides causando un cuadro patológico entérico en tilapia Oreochromis niloticus una piscigranja región Lima, Perú. Las bacterias fueron aisladas e identificadas por técnicas bioquímicas convencionales y confirmadas sistema API 20NE (perfil numérico 7162744 que ratifica a P. al 99.3%). cepas evaluadas (n=4) presentaron metabolismo fermentativo glucosa, positividad las pruebas citocromo oxidasa, indol, Voges-Proskauer rojo...
Abstract Background Newcastle disease (ND) is a major threat to the poultry industry, leading significant economic losses. The current ND vaccines, usually based on active or attenuated strains, are only partially effective and can cause adverse effects post-vaccination. Therefore, development of safer more efficient vaccines necessary. Epitopes represent antigenic portion pathogen their identification use for immunization could lead vaccines. However, prediction protective epitopes...
In the present research, nineteen advanced potato clones with pigmented-fleshed were analyzed in two potato-producing localities Cajamarca, Peru, during agricultural seasons, by means of combined analysis variance, model additive main effects and multiplicative interaction (AMMI) Biplot analysis, to analyze genotype-environment (GEI), order select high stability marketable yield quality. Multivariate showed differences for genotypes, environments GEI. Which states that genetic makeup each...
ABSTRACT The panzootic caused by H5N1 avian influenza viruses is a high concern for wild birds’ conservation and the study of spillover events into mammals. near coding-complete genome clade 2.3.3.4b sequencing in Miseq Illumina platform was performed from bird located Pantanos Villa National Wildlife Refuge.
El objetivo del estudio fue aislar, caracterizar e identificar la bacteria Shewanella algae a partir de muestras órganos internos tilapias (Oreochromis niloticus) enfermas, las cuales estuvieron cultivadas con tecnología biofloc en Lima, Perú; además, se describieron los cambios histopatológicos provocados por el patógeno. Se muestrearon 85 que presentaron signos clínicos enfermedad como exoftalmia, melanosis y nado errático. aislaron siete cepas bacterianas fueron caracterizadas través...
Objetivo: extraer y evaluar la actividad antiviral de los compuestos Chondracanthus chamissoi Chlorella peruviana contra DENV-2 en células Vero-76. Materiales métodos: se extrajeron el carragenano chamissoi, carbohidratos solubles realizó prueba toxicidad VERO-76 evaluación antiviral. Resultados: obtuvieron carragenanos fase esporofito gametofito mismos que fueron identificados, mediante infrarrojo, como k-carragenano. Por cromatografía identificaron nueve azúcares (ribosa, xilosa,...
III. Abstract The Zika virus (ZIKV) of the Flaviviridae family is an emerging that caused, between 2016 and 2018, serious public health problems in Latin America, affecting neonates with greater severity. clinical spectrum includes Guillain-Barré syndrome, microcephaly others neurodegenerative diseases. There no antiviral treatment or vaccine against this virus, for reason properties various plants are being studied. Lippia alba , locally known as “Prontoalivio”, aromatic shrub Verbenaceae a...
El objetivo del estudio fue evaluar cinco niveles de salinidad sobre el crecimiento y productividad Chlorella peruviana Chacon, cepa nativa la laguna salina Mellisera, Chilca, Perú. Se utilizaron tratamientos acuerdo al nivel salinidad: T1, 38‰; T2, 44‰; T3, 59‰; T4, 88‰; T5, 176‰, con una temperatura 27±2 °C intensidad luz 1250±10 lx. Cada tratamiento se realizó por triplicado en matraces 250, 500 1000 ml. Los cultivos realizaron medio f/2 (Guillard), aireación constante fotoperiodo 24:00...
To compare different methods of DNA extraction from cysts and trophozoites Giardia spp. using the conventional polymerase chain reaction (PCR) technique.Cysts were isolated 65 coprological samples national reference hospitals, obtaining an average load 5x104 parasites. In addition, intestinalis (ATCC® 30957™) cultured a 5x106 parasitic load. Eleven for six compared. The concentration purity extracted determined by spectrophotometry yield was assessed amplification ß-giardin (bg) glutamate...
Objetivo: Estandarizar la prueba de microneutralización (MNT) para detección anticuerpos neutralizantes contra el virus dengue serotipo 2 (DENV-2) en línea celular Vero-76. Materiales y métodos: Se evaluaron diferentes concentraciones celulares (0,6 x105 cel/mL, 0,9 1,2 cel/mL), porcentajes 2%, 3% 4% suero bovino fetal (SBF), número pasajes del stock los días incubación. La semilla viral se confirmó por RT-qPCR. El DENV-2 propagó realizando 5 células Vero-76, seguidamente tituló placas 96...
