Atypical actinobacillosis in bulls in Argentina : granulomatous dermatitis and lymphadenitis = Actinobacilose atípica em touros na Argentina: dermatite granulomatosa e linfadenite
Margineda, Carlos Augusto; Odriozola, Ernesto Raul; Moreira, Ana Rita; Canton, German Jose; Micheloud, Juan Francisco; Gardey, Pedro; Spetter, Lucas Maximiliano; Campero, Carlos Manuel (2013-01)Actinobacillosis is a common cause of sporadic infection in cattle. It was mostly characterized as a pyogranulomatous inflammation of the tongue, but also soft tissues as lymph nodes, other digestive tract localization and ... -
Characterization of the first bovine gammaherpesvirus 4 strain isolated from an aborted bovine fetus in Argentina
Romeo, Florencia; Manrique, Julieta; Perez, Sandra; Louge Uriarte, Enrique Leopoldo; Marin, Maia Solange; Canton, German Jose; Leunda, Maria Rosa; González Altamiranda, Erika; Pereyra, Susana Beatriz; Spetter, Lucas Maximiliano; Odeon, Anselmo Carlos; Jones, Leandro; Verna, Andrea Elizabeth (Springer Verlag, 2020-01-24)Bovine herpesvirus 4 (BoHV-4) is increasingly believed to be responsible for several disorders of the bovine reproductive tract. The first characterization of BoHV-4 in Argentina was from samples from an aborted fetus. ... -
Detection and prevalence of bovine viral diarrhea virus in ovarian follicular fluid: A potential risk for in vitro embryo production
Yavorsky, Marisol Solange; Norero, Natalia Sigrid; Spetter, Lucas Maximiliano; Pereyra, Susana Beatriz; Verna, Andrea Elizabeth; Urrutia Luna, Naiara; Rios, Glenda Laura; González Altamiranda, Erika (Elsevier, 2025-08)Bovine Viral Diarrhea Virus (BVDV) and anti-BVDV antibodies have been detected in ovarian follicular fluid of infected cows. The aim of this study was to assess both the frequency of BVDV detection and the prevalence of ... -
Detection methods and characterization of bovine viral diarrhea virus in aborted fetuses and neonatal calves over a 22-year period
Spetter, Lucas Maximiliano; Louge Uriarte, Enrique Leopoldo; Armendano, Joaquín Ignacio; Morrell, Eleonora Lidia; Canton, German Jose; Verna, Andrea Elizabeth; Dorsch, Matías; Pereyra, Susana Beatriz; Odeon, Anselmo Carlos; Saliki, Jeremiah; González Altamiranda, Erika (Springer, 2020-05-16)Detection of bovine viral diarrhea virus (BVDV) in aborted fetus samples is often difficult due to tissue autolysis and inappropriate sampling. Studies assessing different methods for BVDV identification in fetal specimens ... -
Estudio retrospectivo de multirresistencia antimicrobiana en aislamientos de Escherichia coli de terneros con diarrea neonatal = Retrospective study of multiple antimicrobial resistance in Escherichia coli isolates from neonatal calves with diarrhea
Spetter, Lucas Maximiliano; Louge Uriarte, Enrique Leopoldo; González Pasayo, Ramón A.; Malena, Rosana Claudia; Moreira, Ana Rita (2015)Escherichia coli es una de las principales etiologías de la diarrea neonatal de los terneros y el tratamiento de esta enfermedad incluye el uso de antimicrobianos. Se realizó un estudio retrospectivo durante un período de ... -
Frequency of bovine viral diarrhea virus (BVDV) in Argentinean bovine herds and comparison of diagnostic tests for BVDV detection in bovine serum samples: a preliminary study
Spetter, Lucas Maximiliano; Louge Uriarte, Enrique Leopoldo; Armendano, Joaquín Ignacio; Alvarez, Ignacio; Norero, Natalia Sigrid; Storani, Leonardo; Pereyra, Susana Beatriz; Verna, Andrea Elizabeth; Odeon, Anselmo Carlos; Gonzalez Altamiranda, Erika (Elsevier, 2020-11)Bovine viral diarrhea (BVD) is a major worldwide disease with negative economic impact on cattle production. Successful control programs of BVD require the identification and culling of persistently infected (PI) animals ... -
Genetic characterization of bovine herpesvirus 4 (BoHV-4) isolates from Argentine cattle suggests a complex evolutionary scenario
Perez, Sandra; Manrique, Julieta; Moran, Pedro; Romeo, Florencia; Angelini, Hernán Pablo; Leunda, Maria Rosa; Pereyra, Susana Beatriz; Spetter, Lucas Maximiliano; Gonzalez Altamiranda, Erika; Odeon, Anselmo Carlos; Jones, Leandro; Verna, Andrea Elizabeth (Springer Nature, 2020-04)Bovine herpevsirus 4 (BoHV-4) is a gammaherpesvirus that has been associated with different clinical conditions in cattle. In Argentina, BoHV-4 was detected in diverse bovine samples. The aim of this study was to analyze ... -
