Biotechnological applications of occlusion bodies of Baculoviruses
(Springer, 2018-08)The ability of Baculoviruses to hyper-express very late genes as polyhedrin, the major component of occlusion bodies (OBs) or polyhedra, has allowed the evolution of a system of great utility for biotechnology. The main ... -
Biotechnological improvement of ornamental plants
(2017)The discovery of commercial transgenic varieties of orange petunias sold in Europe and the United States although they had never reached the approved status, and the consequent recommendation to destroy them, was the trigger ... -
La biotecnología como herramienta para la conservación y el cuidado de la biodiversidad de las especies aromático-medicinal nativas
(2018-04)En este capítulo se tomaron 11 especies diferentes de PAMs y se muestra una revisión de sus usos populares, sus potenciales aplicaciones, sus correspondientes estados de conservación, y el grado de aplicación de las ... -
BoLA-DRB3 exon2 polymorphisms among tuberculous cattle: Nucleotide and functional variability and their association with bovine tuberculosis pathology
(Elsevier, 2020-06)Bovine tuberculosis (bTB) is caused by Mycobacterium bovis and disseminated worldwide. In Argentina, the highest prevalence occurs in dairy areas. BoLA DRB3.2 is related to the adaptive immunity in mycobacterial infections. ... -
BOLA-DRB3 gene polymorphisms influence bovine leukaemia virus infection levels in Holstein and Holstein × Jersey crossbreed dairy cattle
(2017-05)Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of ... -
Bovine colostral cells : the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)Because bovine maternal and fetal blood supplies are kept separate in utero, calves are immunologically naïve immediately after birth, which puts them at high risk for disease. The acquisition of passive immunity, generally ... -
Bovine colostral cells—the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)At birth, neonatal calves have all the essential immune components they need as adult cattle; however, it takes at least 2 to 4 weeks for those components to become fully functional.1,2 The immune system does not become ... -
Bovine coronavirus in Uruguay: genetic diversity, risk factors and transboundary introductions from neighboring countries
(Springer, 2019-11)Bovine coronavirus (BCoV) is a recognized cause of severe neonatal calf diarrhea, with a negative impact on animal welfare, leading to economic losses to the livestock industry. Cattle production is one of the most important ... -
Bovine dendritic cell activation, T cell proliferation and antibody responses to foot-and-mouth disease, is similar with inactivated virus and virus like particles
(Frontiers Media, 2020-09)Foot-and-mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals that causes severe economic losses in the livestock industry. Currently available vaccines are based on the inactivated FMD virus (FMDV). ... -
Bovine interferon lambda Is a potent antiviral against SARS-CoV-2 infection in vitro
(Frontiers Media, 2020-11)Interferon lambda (IFN-λ) is an antiviral naturally produced in response to viral infections, with activity on cells of epithelial origin and located in the mucosal surfaces. This localized activity results in reduced ... -
Bovine leukemia virus becomes established in dairy herds before the first lactation
(2016)In this work, we studied seven groups of pregnant heifers from a consortium of dairy farms heavily infected with bovine leukemia virus (BLV). ELISA testing showed that the seroprevalence ranges of BLV in heifers between ... -
Bovine leukemia virus encoded blv-miR-b4-3p microRNA is associated with reduced expression of anti-oncogenic gene in vivo
(PLOS, 2023-02)Bovine leukemia virus (BLV) is a retrovirus that causes malignant B-cell lymphoma in up to ten-percent of infected cattle. To date, the mechanisms of BLV linked to malignant transformation remain elusive. Although BLV-encoded ... -
Bovine leukemia virus infection in neonatal calves. Risk factors and control measures
(Frontiers Media, 2018-10)Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis (EBL). Although efficient eradication programs have been successfully implemented in most European countries and Oceania, BLV infection rates ... -
Bovine leukemia virus small noncoding RNAs are functional elements that regulate replication and contribute to oncogenesis in vivo
(2016-04)Retroviruses are not expected to encode miRNAs because of the potential problem of self-cleavage of their genomic RNAs. This assumption has recently been challenged by experiments showing that bovine leukemia virus (BLV) ... -
Bovine macrophages responses to the infection with virulent and attenuated Leptospira interrogans serovar Pomona
(Elsevier, 2019-06)Leptospirosis is a zoonosis, caused by pathogenic spirochetes of the genus Leptospira. Although cattle are usually the maintenance hosts of serovar Hardjo, Pomona is the most frequent serovar circulating in Argentina. The ... -
Bovine respiratory syncytial virus seroprevalence and risk factors in feedlot cattle from Córdoba and Santa Fe, Argentina = Seroprevalencia del virus respiratorio sincicial bovino y factores de riesgo asociados en engordes a corral de Córdoba y Santa Fe, Argentina
(2018-09)Bovine respiratory syncytial virus (BRSV) is one of the causative agents of respiratory disease in cattle all over the world, leading to important economic losses. The aim of this work was to determine the seroprevalence ... -
Bovine rotavirus strains circulating in beef and dairy herds in Argentina from 2004 to 2010
(Elsevier, 2012-08-17)Bovine Group A Rotavirus (RVA) is one of the main causes of neonatal calf diarrhea worldwide. The present study reports the genotyping of bovine RVA strains circulating in Argentinean cattle from 2004 to 2010. Additionally, ... -
Bovine tuberculosis in domestic pigs: Genotyping and distribution of isolates in Argentina
(Elsevier, 2015-12)Bovine tuberculosis is caused by Mycobacterium bovis and affects primarily cattle, among many other mammal species. In this study, 250 isolates of M. bovis collected from pigs slaughtered in Argentina were typed by ... -
