Pathogenesis of Brucella suis biovar 1 in the armadillo (Chaetophractus villosus).

Brucella suis biovar 1 has the broadest animal host spectrum. Affects domestic animals and wildlife species. The aim of our study was to investigate the pathogenesis of B.

Study on the interference of vaccine antibodies with the serological diagnosis of leptospirosis in cattle.

A simple IgG-specific ELISA for Leptospira spp. was compared with the microscopic agglutination test (MAT) to detect IgG antibody responses to a commercial vaccine in cattle. We used an enzyme-linked immunosorbent assay (ELISA) with sonicated Leptospira interrogans serovar copenhageni M 20.

Comparison of ELISA using recombinant LipL32 and sonicated antigen of leptospira for detecting bovine leptospirosis.

Leptospirosis is one of the most widely distributed zoonosis in the world. Bovine leptospirosis is a serious problem in bovine production, causing reproductive losses. The aim of this work was to compare recombinant LipL32 with sonicated antigen for detecting anti-Leptospira IgG antibodies in bovine serum using ELISA.

New enzyme-linked immunoassay for the detection of specific antibodies against multiple Leptospira serogroups in bovine sera.

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, causing abortions, reduced milk yield, mortality in calves and decreased daily weight gain. We developed an enzyme-linked immunosorbent assay (ELISA) with sonicated Leptospira interrogans serogroup Icterohaemorrhagiae serovar Copenhageni M 20.

Ectoparasites from some Myocastor coypus (Molina, 1782) populations (Coypus or Nutria) in Argentina.

The occurrence of ectoparasites in wild nutria is poorly understood. Fifty-five livetrapped wild nutria (Myocastor coypus) from its indigenous region were examined for ectoparasites after capture from December 2013 to December 2014. The captures came from the Buenos Aires Province, by far the area of the country most densely populated by nutria, characterized as a temperate grassland, which are prime areas for sustained agriculture.
