Identificación de factores de riesgo de tuberculosis bovina en rodeos lecheros
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2009-09)La tuberculosis bovina (TBB), producida por el Mycobacterium bovis (M. bovis), es una enfermedad zoonótica endémica en los rodeos bovinos de la Argentina. La información sobre la asociación entre el manejo y la ocurrencia ... -
Necrotic Enteritis in Young Calves
(Sage Publishing, 2011-03)Non–enterotoxin (CPE)–producing Clostridium perfringens type A has been associated with enteritis in calves. Recent evidence has suggested that a novel toxin, named beta2 (CPB2), is implicated in the pathogenesis of this ... -
Foot‐and‐Mouth Disease in pigs: current epidemiological situation and control methods
(Wiley, 2012-03)Foot‐and‐mouth disease (FMD) is the paradigm of a transboundary animal disease. Beyond any doubt, it is the most serious challenge for livestock’s health. Official Veterinary Services from free countries invest considerable ... -
Genetic analysis of the 3′ untranslated region of the bovine SLC11A1 gene reveals novel polymorphisms
(Springer, 2013-01)Polymorphisms in microsatellites at the 3′ untranslated region (3′UTR) of the SLC11A1 (solute carrier family 11 member A1) gene have been associated with natural resistance to Brucella abortus and Mycobacterium bovis ... -
Serological Analysis by Enzyme-Linked Immunosorbent Assay Using Recombinant Antigen LipL32 for the Diagnosis of Swine Leptospirosis
(Springer, 2013-02)Leptospirosis is an important global zoonotic disease caused by pathogenic Leptospira spp. species. Swine leptospirosis has a major economic impact because pigs are sources of animal protein and by-products. The signs of ... -
In vitro diagnosis of the first case of amitraz resistance in Rhipicephalus microplus in Santo Tomé (Corrientes), Argentina
(Elsevier, 2013-02)In Argentina, the cattle tick Rhipicephalus microplus has already developed resistance to organophospates and synthetic pyrethroids. However, no cases of amitraz resistance have ever been recorded in this country despite ... -
Presencia de zearalenona en pasturas del este de Chaco
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-04)Se estudió la presencia de zearalenona en pasturas y alimentos que son utilizados para la producción de bovinos de carne de la zona este de la provincia del Chaco. Asimismo, se realizó el aislamiento e identificación de ... -
Identificación morfológica y molecular de Cysticercus fasciolaris aislado de un roedor (Rattus norvegicus) de la provincia de Buenos Aires (Argentina) = Morphological and molecular identification of Cysticercus fasciolaris isolated from rodent hosts (Rattus norvegicus) in Buenos Aires province (Argentina)
(Elsevier, 2013-07)En un estudio exploratorio de roedores de la especie Rattus norvegicus de la provincia de Buenos Aires, se observó que ciertos metacestodos de tenias se encontraban enquistados en el hígado del hospedador. Nuestro objetivo ... -
Isolation of Pseudobutyrivibrio ruminis and Pseudobutyrivibrio xylanivorans from rumen of Creole goats fed native forage diet
(Springer, 2013-09)We isolated and identified functional groups of bacteria in the rumen of Creole goats involved in ruminal fermentation of native forage shrubs. The functional bacterial groups were evaluated by comparing the total viable, ... -
Mutation in the RmβAOR gene is associated with amitraz resistance in the cattle tick Rhipicephalus microplus
(National Academy of Sciences, 2013-10)We aimed to describe the evolution of resistance to amitraz in Rhipicephalus microplus in the field and to test the association between amitraz resistance and the frequency of a mutation in the β-adrenergic octopamine ... -
Evidence for extensive genetic diversity and substructuring of the Babesia bovis metapopulation
(2013-11)Babesia bovis is a tick-transmitted haemoprotozoan and a causative agent of bovine babesiosis, a cattle disease that causes significant economic loss in tropical and subtropical regions. A panel of nineteen micro- and ... -
Manejo de Llamas extra-andinas. Observaciones que contribuyen a su bienestar en un contexto no originario
(Asociación Argentina de Producción Animal, 2013-12)El uso de camélidos sudamericanos (CSA) se remonta a 12000 años atrás, cuando los primeras poblaciones humanas comenzaron a cazar guanacos (Lama guanicoe) y vicuñas (Vicugna vicugna), CSA silvestres, para alimentarse. ... -
Molecular characterization of Cryptosporidium isolates from calves in Argentina
(2013-12)Cryptosporidiosis is responsible for significant fatalities of neonatal calves, resulting in substantial economic loss in dairy farming in several countries. Additionally, the high shedding of environmentally resistant ... -
Molecular identification of Sarcocystis aucheniae as the macrocyst-forming parasite of llamas
(2013-12)The domestic South American camelids (SACs), llama (Lama glama) and alpaca (Lama paco), are frequently found to be infected with Sarcocystis parasites. Infections give rise in skeletal muscle to macroscopic cysts (1–5 mm ... -
