The goal of this study was to investigate anti-Rickettsia spp. antibodies in sera of domestic chickens (Gallus gallus domesticus) of extensive breeding in Cerro Largo county, considered an endemic area for spotted fever in the State of Rio Grande do Sul, Brazil. Three hundred blood samples were collected and anti-Rickettsia spp. antibodies were evaluated by indirect immunofluorescence assay (IFA) in the sera obtained. The occurrence of anti-Rickettsia spp. antibodies detected in this study was 1.33% (4/300), with endpoint titers ranging from 64 to 256 for Rickettsia rickettsiii, R. parkeri and/or R. bellii. The results suggest these domestic chickens do not participate as a reservoir and/or amplifying host in the epidemiology of spotted fever in that...

Mello,Josiane Medeiros de; Orsi,Antonio Marcos; Padovani,Carlos Roberto; Matheus,Selma Maria Michelin; Torrejais,Márcia Miranda; Ribeiro,Antonio Augusto Coppi Maciel.
The segmental structure of the aortic wall at the thoracic and abdominal levels were studied in domestic chicken by light microscopy (LM) and scanning electron microscopy (SEM). Selected histological sections were submitted to histomorphometric studies using image analysis methods. The variables studied were the thickness of the aortic layers in the three segments investigated: ascendant thoracic, descendant thoracic and abdominal parts as well as the tubular diameters and the mean number of elastic lamellae in the medial layer of each analyzed segment. The aortic wall of the chicken had a predominately elastic structure in the thoracic portions, that decrease gradually in relative number of elastic lamellae towards the abdominal aorta in which smooth...
