El comportamiento de acicalamiento de Apis mellifera hacia el ácaro Varroa destructor : Bases fenotípicas y genéticas e implicancia sobre la resistencia a la varroosis
(Facultad de Agronomía, Universidad de Buenos Aires, 2023-08)Apis mellifera es un insecto polinizador clave y constituye el mayor productor de miel para consumo humano. Uno de los principales patógenos de las abejas melíferas es el ácaro Varroa destructor. Este ectoparásito generalmente ... -
Enhanced infectivity of bovine viral diarrhoea virus (BVDV) in arginase-producing bovine monocyte-derived macrophages
(Taylor & Francis, 2024)Macrophages are important cells of the innate immunity that play a major role in Bovine Viral Diarrhoea Virus (BVDV) pathogenesis. Macrophages are not a homogenous population; they exist in different phenotypes, typically ... -
Stimulus-specific gene expression profiles associated with grooming behavior and Varroa destructor resistance in honey bees
(Frontiers Media, 2024-07)Grooming behavior is one of the mechanisms of social immunity in Apis mellifera. This behavior has been proposed as an active strategy of honey bees to restrain the population growth of the ectoparasitic mite Varroa ... -
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 ... -
Temporal host–symbiont dynamics in community contexts : Impacts of host fitness and vertical transmission efficiency on symbiosis prevalence
(Wiley, 2024-12)Symbiotic associations play a role in plant ecology and evolution, but the outcome of the interaction depends on the life-history traits of the partners and the environmental context. Although symbiosis with vertically ... -
Dietary supplementation improves animal performance and reduces methane emission intensity in young llamas grazing natural forages
(Elsevier, 2025-04)The aim of this study was to evaluate the effects of concentrate supplementation on animal performance, enteric methane (CH4) emissions, and forestomach (C1-C2 and C3) fermentative parameters of young llamas grazing on ... -
Evaluation of LigB polymerase chain reaction as a complementary tool to microscopic agglutination test for the detection of bovine leptospirosis in serum samples
(Elsevier, 2025-05)Leptospirosis is a significant infectious disease affecting livestock. Microscopic agglutination test (MAT) is used as the gold standard; however, the inclusion of molecular tools (PCR) could improve the accuracy of ... -
Molecular markers for analyses of genetic diversity within the Anastrepha fraterculus complex with emphasis on Argentine populations
(MDPI, 2024-10)The South American fruit fly Anastrepha fraterculus (Wiedmann) has a vast range extending from northern Mexico, through Central America, to South America where it is an extremely polyphagous pest of wild and cultivated ... -
Exploring the molecular differentiation of sex chromosomes in Anastrepha fraterculus sp. 1 using comparative genomic hybridization (CGH)
(Springer, 2025-02)Background: The South American fruit fly Anastrepha fraterculus sp. 1 belongs to a cryptic species complex with only a single morphotype present in Argentina, which possess polymorphisms in the sex chromosomes, identified ... -
Arabidopsis research in 2030: Translating the computable plant
(Wiley, 2025-03)Plants are essential for human survival. Over the past three decades, work with the reference plant Arabidopsis thaliana has significantly advanced plant biology research. One key event was the sequencing of its genome ... -
Shedding light on risk: Seroprevalence of Q fever among farm animals and workers in Ecuador
(Elsevier, 2024-12)Q fever, caused by the bacterium Coxiella burnetii, is a zoonotic disease that has been largely overlooked despite presenting significant risks to both animal and public health. Although well studied in some countries, in ... -
Ecophysiological and Molecular Analysis of Contrasting Genotypes for Leaf Senescence in Sunflower (Helianthus annuus L.) Under Differential Doses of N in Soil
(MDPI, 2024-12)Leaf senescence in plants is the last stage of leaf development and is characterized by a decline in photosynthetic activity, an active degeneration of cellular structures, and the recycling of accumulated nutrients to ... -
FhaA plays a key role in mycobacterial polar elongation and asymmetric growth
(American Society for Microbiology, 2025-03)Mycobacteria, including pathogens like Mycobacterium tuberculosis, exhibit unique growth patterns and cell envelope structures that challenge our understanding of bacterial physiology. This study sheds light on FhaA, a ... -
