| Popis: | ABSTRAT Arthritis implies inflammation of the intra-articular structures and is one of the causes of condemnation in broilers. The disease is associated with infectious agents such as Staphylococcus aureus, which may pose a potential public health risk. This work was conducted with the objective to determine the occurrence of arthritis in broiler chickens, predominantly of bacterial staphylococcal origin and if there is a difference between the degrees of injury regarding the presence of the bacterium and the histological lesion. Sixty samples of chickens diagnosed with arthritis by Federal Inspection Service from commercial slaughterhouse were collected according to their severity (of mild and severe degree) and submitted to bacteriological and histopathological analysis. There was bacterial growth of Staphylococcus aureus in 3.3% of the samples classified as mild degree in 10% of the samples classified as severe grade of lesion (p=0,29). For histopathological evaluation, 16.67% and 70% of the samples presented inflammatory infiltrate in mild and severe degrees, respectively (p=0,0001). Mild degree arthritis is related to non-infectious lesions in their higher prevalence while severe-grade arthritis has infectious causes. The condemnation criteria were efficient since S. aureus could be present regardless of the degree of the lesion diagnosed in arthritis. |
