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 ... -
Combinación de vacunas vivas e inactivadas para el control de la Tifosis aviar en gallinas ponedoras
(Asociación Latinoamericana de Avicultura, 2024-11)Introducción: La Tifosis aviar (TA), producida por Salmonella Gallinarum (SG), es una enfermedad que genera alta mortalidad y se encuentra distribuida por la mayor parte de los países de Latinoamerica, Asia, África y también ... -
Comparative transcriptome analysis of geographically distinct virulent and attenuated Babesia bovis strains reveals similar gene expression changes through attenuation
(2013-11)Background: Loss of virulence is a phenotypic adaptation commonly seen in prokaryotic and eukaryotic pathogens. This mechanism is not well studied, especially in organisms with multiple host and life cycle stages such as ... -
Comparison of the application of the attenuated Salmonella Enteritidis or Salmonella Typhimurium vaccines by different routes in chicks
(Asociación Española de Ciencia Avícola, 2025-09)Introduction: Salmonella Enteritidis (SE) and S.Typhimurium (ST) are the two most important zoonotic Salmonella serovars and, together with biosecurity measures, the use of livevaccines isthemainstrategy to reduce the ... -
Cross-protection conferred by live-attenuated Salmonella Enteritidis vaccine against S. Heidelberg and S. Infantis
(American Association of Avian Pathologists, 2024-07)Salmonella infection is one of the main causes of foodborne illnesses worldwide historically associated with the consumption of eggs and chicken meat. While S. Enteritidis (SE) and S. Typhimurium are the most prevalent ... -
Diferenciación de una cepa vacunal de Salmonella Enteritidis de aislamientos de campo mediante un medio de cultivo con antibióticos
(Asociación Latinoamericana de Avicultura, 2024-11)La vacunación de las aves para el control de Salmonella es una de las estrategias más eficaces para reducir la excreción y la colonización del patógeno, disminuyendo de esta manera su transmisión a través de los alimentos. ... -
Eficacia de una vacuna viva atenuada de Salmonella frente a la infección por S. Enteritidis en aves de 15 y 30 días
(Asociación Latinoamericana de Avicultura, 2024-11)Salmonella es uno de los principales microorganismos responsables de infecciones alimentarias en los seres humanos, siendo los productos avícolas una de las principales fuentes de transmisión. La vacunación de las aves es ... -
Field trial with vaccine candidates against bovine tuberculosis among likely infected cattle in a natural transmission setting
(MDPI, 2024-10)Background/Objectives: Vaccines may improve the control and eradication of bovine tuberculosis. However, the evaluation of experimental candidates requires the assessment of the protection, excretion, transmission and ... -
Live attenuated Mycobacterium bovis strains combined with the encapsulated H65 antigen as a vaccine strategy against bovine tuberculosis in a mouse model
(Elsevier, 2024-04)Mycobacterium bovis is an etiological agent of bovine tuberculosis (bTB) that also infects other mammals, including humans. The lack of an effective vaccine for the control of bTB highlights the need for developing new ... -
Mycobacterium bovis Dmce2 double deletion mutant protects cattle against challenge with virulent M. bovis
(Elsevier, 2013-05)A Mycobacterium bovis strain deleted in mce2A and mce2B genes (M. bovis Δmce2) was tested as an experimental vaccine in cattle challenged with a virulent M. bovis strain. Three-and-a-half-month old calves (n = 5 to 6 per ... -
Mycobacterium bovis mutant in the virulence factors PhoP, ESAT-6 and CFP-10 persisted in mouse organs after a year post-vaccination
(Elsevier, 2024-12)A vaccine for bovine tuberculosis is urgently needed. The BCG vaccine (the Bacille Calmette-Guérin), currently the only licensed vaccine for tuberculosis in humans, offers variable protection in cattle. However, BCG is a ... -
Protección conferida por un inmunomodulador solo o en combinación con una vacuna viva atenuada frente al desafío con Salmonella Enteritidis
(Asociación Latinoamericana de Avicultura, 2024-11)La presencia de Salmonella en la cadena de producción avícola tiene impactos negativos tanto en la salud de las aves como en la de los consumidores, ya que este patógeno puede transmitirse a través de los alimentos. La ... -
Protection induced by a glycoprotein E-deleted bovine herpesvirus type 1 marker strain used either as an inactivated or live attenuated vaccine in cattle
(BMC, 2014-01)Background: Bovine herpesvirus type 1 (BoHV-1) is the causative agent of respiratory and genital tract infections; causing a high economic loss in all continents. Use of marker vaccines in IBR eradication programs is widely ... -
Vaccines against bovine babesiosis: where we are now and possible roads ahead
(Cambridge University Press, 2014-10)Bovine babesiosis caused by the tick-transmitted haemoprotozoans Babesia bovis, Babesia bigemina and Babesia divergens commonly results in substantial cattle morbidity and mortality in vast world areas. Although existing ...
