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 ... -
Morbilidad y mortalidad en terneras de rodeos lecheros con manejo intensivo del calostrado
(Asosiación Argentina de Veterinarios de Laboratorios de Díagnóstico, 2021-11)La producción lechera en Argentina ha registrado durante los últimos años una reducción en el número de tambos y del número de vacas a una tasa del 3,4% y 1.4% anual, respectivamente (OCLA, 2018). La ineficiencia reproductiva ... -
N-Glycosylation in piroplasmids : Diversity within simplicity
(MDPI, 2021-01)N-glycosylation has remained mostly unexplored in Piroplasmida, an order of tick-transmitted pathogens of veterinary and medical relevance. Analysis of 11 piroplasmid genomes revealed three distinct scenarios regarding ... -
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 ... -
New enzyme-linked immunoassay for the detection of specific antibodies against multiple Leptospira serogroups in bovine sera
(Elsevier, 2021-04)Leptospirosis is a zoonotic disease with worldwide endemicity in Argentina, it is a significant public health problem in low-income populations. Bovine leptospirosis is a serious economic problem for cattle production, ... -
New scenarios for brucella suis and brucella melitensis
(Springer, 2017-03)Purpose of Review: We pretend to highlight the most important advances reached in the last few years in the biology of Brucella suis and Brucella melitensis and focus attention on new tools for the comprehension, prevention ... -
Next-generation technologies and systems biology for the design of novel vaccines against apicomplexan parasites
(Frontiers Media, 2022-01)Parasites of the phylum Apicomplexa are the causative agents of important diseases such as malaria, toxoplasmosis or cryptosporidiosis in humans, and babesiosis and coccidiosis in animals. Whereas the first human recombinant ... -
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 ... -
On the use of the SF6 gas tracer technique in Latin America for measuring methane emissions in ruminants : a review and analysis
(Taylor and Francis, 2024)The SF6 gas tracer technique is extensively used to measure enteric CH4 emissions for scientific research in Latin-American countries. Although guidelines on how to properly implement this technique have been published, ... -
Optimization and comparative analysis of LAMP and PCR techniques for the detection of leptospiral DNA in Golden Syrian hamsters
