(Elsevier, 2021-09)Leptospirosis is an endemic disease caused by Leptospira spp., a bacterium that affects animals and humans. In recent years, the number of reports of leptospirosis in wild animals has increased, which highlights the need ... -
Occurrence of Cryptosporidium and other enteropathogens and their association with diarrhea in dairy calves of Buenos Aires province, Argentina
(Elsevier, 2021-04)Cryptosporidiosis of neonatal dairy calves causes diarrhea, resulting in important economic losses. In Argentina, prevalence values of Cryptosporidium spp. and other enteropathogens such as group A rotavirus (RVA), bovine ... -
Babesia bovis AMA-1, MSA-2c and RAP-1 contain conserved B and T-cell epitopes, which generate neutralizing antibodies and a long-lasting Th1 immune response in vaccinated cattle
(Elsevier, 2022-02)Vaccines against bovine babesiosis must, ideally, induce a humoral immune response characterized by neutralizing antibodies against conserved epitopes and a cellular Th1 immune response. In Babesia bovis, proteins such as ... -
Development of a loop-mediated isothermal amplification (LAMP) and a direct LAMP for the specific detection of Nosema ceranae, a parasite of honey bees
(Springer, 2020-10)Nosema ceranae is a ubiquitous microsporidian pathogen infecting the midgut of honey bees. The infection causes bee nosemosis, a disease associated with malnutrition, dysentery, and lethargic behavior, and results in ... -
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 ... -
Kinetic characterization of a novel cysteine peptidase from the protozoan Babesia bovis, a potential target for drug design
(Elsevier, 2020-12)C1A cysteine peptidases have been shown to play an important role during apicomplexan invasion and egress of host red blood cells (RBCs) and therefore have been exploited as targets for drug development, in which peptidase ... -
Use of Chelex-100 for the molecular diagnosisof five animal pathogens
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2021-06)Molecular tools have improved conventional veterinary diagnosis. Acid nucleic extraction is a key step for downstream applications. This work aimed to compare the DNA extraction method Chelex-100 resin (M1) ... -
Detección de Leptospira spp. (Spirochaetales: Leptospiraceae) en muestras ambientales de regiones habitadas por poblaciones vulnerables del norte argentino
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2021-12)La leptospirosis continúa siendo hoy en día un problema para la salud pública, principalmente en poblaciones de bajos recursos socioeconómicos. En este trabajo se presenta la detección de leptospiras patógenas en muestras ... -
Molecular characterization and antimicrobial resistance profiles of Salmonella Heidelberg isolates from poultry
(Wiley, 2021-02)In the last 10 years, Salmonella Heidelberg has been extensively isolated from poultry in several countries. In this context, molecular characterization is essential to understand whether the strains have entered the farms ... -
Molecular evidence of Leishmania spp. in spider monkeys (Ateles geoffroyi) from The Tuxtlas Biosphere Reserve, Veracruz, Mexico
