A spatiotemporal analysis of bovine brucellosis cases in dairy herds from Argentina, from 2014 to 2023
Novoa, María Belén; Aguirre, Nerina; Ugarte, Estefanía; Foster, Camila Nayla; Molineri, Ana Ines; Signorini Porchiett, Marcelo Lisandro; Molina, Alberto Martín; Vanzini, Victor Rene (Springer, 2025-09)Brucellosis is a bacterial infection that causes abortion in cattle, poses a significant public health risk, and causes economic losses in livestock production. This study analyzed passive epidemiological surveillance data ... -
Development and Bayesian analysis of a competitive inhibition ELISA for caprine brucellosis
Foster, Camila Nayla; Monzon, Nolly María; Signorini Porchiett, Marcelo Lisandro; Aznar, Maria Natalia; Aguirre, Nerina Patricia; Valentini, Beatriz Susana; Vanzini, Víctor René; Novoa, María Belén (Elsevier, 2025-05)Caprine brucellosis, caused by Brucella melitensis, is a zoonotic disease responsible for abortions in goats and is endemic in several countries. Control measures include vaccination, serological assays, and culling of ... -
Development and Bayesian validation of a competitive inhibition ELISA for detection of antibodies against Brucella abortus in cattle
Novoa, María Belén; Aguirre, Nerina; Valentini, Beatriz Susana; Signorini Porchiett, Marcelo Lisandro; Aznar, Maria Natalia; Vanzini, Victor Rene; Torioni, Susana Marta (Elsevier, 2024-09)Bovine brucellosis is a zoonotic disease caused by Brucella abortus, responsible for abortions in cows. It is endemic in low- and middle-income countries, where the brucellosis control and eradication programs are based ... -
Development, validation and field evaluation of an indirect ELISA for the detection of antibodies against Brucella abortus in bulk and individual milk samples in dairy cattle
Novoa, María Belén; Aguirre, Nerina; Valentini, Beatriz Susana; Torioni, Susana Marta; Signorini Porchiett, Marcelo Lisandro; Primo, María Evangelina; Elena, Sebastián Alejandro; Vanzini, Victor Rene (Elsevier, 2022-11)Brucellosis is an abortigenic and zoonotic disease. In cattle, it is mainly caused by Brucella abortus. The disease is endemic in low- and middle-income countries, being considered a neglected zoonotic disease. In these ... -
Evaluation of frequency of antibodies against Neospora caninum, Toxoplasma gondii and Brucella melitensis, risk factors and spatial distribution of infection in goat and sheep flocks from Argentina
Novoa, María Belén; Aguirre, Nerina; Ormaechea, Nadia; Palmero, Sebastian; Valentini, Beatriz Susana; Vanzini, Victor Rene; Molineri, Ana Ines (Elsevier, 2023-11)Neospora caninum, Toxoplasma gondii and Brucella melitensis are pathogens that cause abortion in small ruminants. Besides, B. melitensis and T. gondii are zoonotic pathogens. The aim of this study was to describe the ... -
Validation and field evaluation of a competitive inhibition ELISA based on the recombinant protein tSAG1 to detect anti-Neospora caninum antibodies in sheep and goats
Novoa, María Belen; Aguirre, Nerina; Ormaechea, Nadia; Palmero, Sebastián; Rouzic, Lisandro; Valentini, Beatriz Susana; Sarli, Macarena; Orcellet, Viviana Mercedes; Marengo, Rafael; Vanzini, Victor Rene; Primo, María Evangelina (Elsevier, 2020-08)Neospora caninum is a protozoan parasite that causes abortion and reproductive failure in small ruminants. We validated and evaluated under field conditions a competitive inhibition ELISA based on the truncated SAG1 protein ...
