Membranoproliferative glomerulonephritis was observed in a seven-month-old male cocker spaniel dog. The clinical, microbiological, biochemical, radiographic and ultrasonographic examinations ruled out neoplasia, congenital disease and infectious disease. The anamnesis revealed that the owner had ...

The aim of this study was to determine if mice exposed to Aspergillus (A.) fumigatus spores develop airway inflammation in a similar manner to Recurrent Airway Obstruction (RAO) in horses. Different groups of 2-, 5-, 6- and 8-month-old Rockefeller (RK) mice were used throughout the experiment. Th...
El objetivo de este estudio fue determinar si ratones expuestos a esporas de Aspergillus fumigatus desarrollan una inflamación alérgica de las vías respiratorias similar a la observada en equinos con Obstrucción Recurrente de las Vías Aéreas (ORVA). Para esto se utilizaron ratones Rockefeller (RK...

In this study, the presence and characteristics of the recurrent airway obstruction (RAO), in Chilote horses were investigated. The Chilote horse is a breed of small and very rustic horses, descendent from, the horses that were brought by the Spaniards during the colony and remained isolated in. ...
El objetivo de este estudio fue analizar las características citológicas del lavado bronquealveolar (LBA) y la respuesta inmune humoral en caballos Chilote con obstrucción recurrente de las vías aéreas (ORVA) contra Aspergillus fumigatus y su rol en la inducción de este cuadro alérgico. Para esto...

Neutrophils are the predominant inflammatory cells that infiltrate airways during acute exacerbation of asthma. The importance of A. fumigatus sensitization, and IgE response in the airways in patients with acute asthma is unclear. Rockefeller (RK) mice were sensitized with A. fumigatus extract p...

We report on 2 cases of recurrent airway obstruction (RAO) observed in Chilean Criollo horses aged 13 and 15 years. Both animals were classified as having severe RAO. The analysis of the recovered cells of bronchoalveolar lavage fl uid (BALF) showed high percentages of eosinophils (82% and 80% in...

Macrophages and neutrophils are important cellular components in the process of acute inflammation and its subsequent resolution, and evidence increasingly suggests that they play important functions during the resolution of chronic, adaptive inflammatory processes. Exacerbated neutrophil activit...
