Environmental infestation and rickettsial infection in ticks in an area endemic for Brazilian spotted fever Infestação ambiental e infecção por rickéttsias em carrapatos de área endêmica para Febre Maculosa Brasileira
Brazilian spotted fever (BSF), caused by Rickettsia rickettsii, is endemic in the municipality of Americana, southeastern Brazil, where the disease is transmitted by the tick Amblyomma cajennense. This study evaluated the tick fauna and rickettsial infection in free-living ticks that were captured monthly using dry ice traps in areas endemic for BSF in Americana, from July 2009 to June 2010. Tw...

The mechanisms for intraseasonal variability of the southern hemisphere (SH) winter are studied using a nonlinear non-divergent barotropic potential vorticity model on the sphere. The possibility of low frequency unstable modes induced by topography is examined to compare with the northern hemisphere (NH) case. According to this simple model for the SH winter the most important mechanism in cre...
