(2014-11)The aim of this work was to describe for the first time the presence of Borrelia burgdorferi sensu lato infecting ticks in Argentina. Unfed specimens of Ixodes pararicinus collected from vegetation in Jujuy Province were ... -
Caracterización diagnóstica de las causas infecciosas del aborto bovino
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2010)El objetivo del presente estudio fue el desarrollo y la aplicación de técnicas diagnósticas mejoradas para aumentar la eficiencia del diagnóstico del aborto bovino. Para ello, se realizó la necropsia de 150 fetos bovinos, ... -
Characterization of immune response in Staphylococcus aureus chronically infected bovine mammary glands during active involution
(2017-10)The aim of this study was to characterize the immune response in Staphylococcus aureus chronically infected bovine mammary glands during active involution. Twenty-one Holstein non-pregnant cows in late lactation either ... -
Evaluación de la virosis del achaparramiento de la alfalfa (Medicago sativa L.) en dos ambientes contrastantes de Argentina = Alfalfa dwarf disease evaluation (Medicago sativa L.) in two contrasting environments in Argentina
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2017)En los últimos años se vienen observando daños crecientes de una enfermedad viral que afecta la producción y la persistencia del cultivo de alfalfa en Argentina. El objetivo de este trabajo fue comparar la incidencia y ... -
Evaluation of Tritrichomonas foetus infection clearance in heifers immunized with a single intravaginal dose of formaldehyde fixed strain B1 cells
(Elsevier, 2018-05-15)Vaccines against Tritrichomonas foetus have been shown to reduce the time of infection after natural or experimental exposure. The object of this study was to assess the protection against T. foetus infection conferred by ... -
In vitro plants of Vitis vinifera respond to infection with the fungus Phaeoacremonium parasiticum by synthesizing the phytoalexin nerolidol
(Springer, 2019-09)This study investigated terpene biosynthesis in basal and apical tissues of in vitro-grown plants of Vitis vinifera cv. Chardonnay infected or not (control) with Phaeoacremonium parasiticum. This pathogen is one of the ... -
Infection with different Neospora caninum strains causes differences in the glycosylation pattern in the uteri and placentae of Neospora caninum-infected heifers
(Elsevier, 2024-04)Neospora caninum is an obligate intracellular parasite that causes abortion in ruminants. Different strains produce differences in the severity of disease outcomes. These differences may cause physiological or pathological ... -
Lectin binding patterns and immunohistochemical antigen detection in placenta and lungs of Brucella abortus-bovine infected fetuses
(2018)Lectin binding relies on the affinity of these substances for specific terminal sugars. The method facilitates the identification of complex structures to which the terminal sugar attaches and may reveal physiological or ... -
Liolaemus lizards (Squamata: Liolaemidae) as hosts for the nymph of Amblyomma parvitarsum (Acari: Ixodidae), with notes on Rickettsia infection
(2016)Adults of Amblyomma parvitarsum are common ectoparasites of South American camelids of the genera Lama and Vicugna, occuring in highlands of Argentina, Bolivia, Chile, Peru and also in Argentinean Patagonia. Whereas larval ... -
Microscopic lesions and modulation of gene expression in cervical medulla during BoAHV-1and BoAHV-5 infection: A mini-review
(Elsevier, 2023-03)Bovine herpesvirus (BoAHV) types 1 and 5 are closely-related neurotropic alpha-herpesviruses. BoAHV-1 generally causes respiratory and genital disease but can occasionally cause encephalitis. BoAHV-5 is the causative agent ... -
Modulation of Apoptosis by Bovine Gammaherpesvirus 4 Infection in Bovine Endometrial Cells and the Possible Role of LPS in This Process
(MDPI, 2024-04-08)The prevalent pathogens associated with bovine uterine infections are bacteria that appear to increase the host’s susceptibility to secondary infections with other bacteria or viruses, among which BoGHV4 is the most ... -
Relationship of Salmonella infection and inflammatory intestinal response with hematological and serum biochemical values in laying hens
(2015-06)There are few studies about the blood serum of laying hens infected with Salmonella. The differential leukocyte count and blood chemistry values are an important aid in the diagnosis of human diseases, but blood parameters ... -
