ABSTRACT The maintenance of wild animals in captivity can be a source for transmission of infectious and zoonotic diseases. In February 2016, blue-fronted amazon parrots that were kept at the Centro de Reabilitação de Animais Silvestres (CRAS) of Campo Grande - MS died suddenly. The specimens were sent to the Universidade Federal de Mato Grosso do Sul (UFMS), Faculdade de Medicina Veterinária e Zootecnia (FAMEZ) to be necropsied. Anatomopathological exams were performed and organ fragments from all systems were collected for histopathological exams. Liver and spleen fragments were also collected for bacteriological exams. Histopathological exam revealed bacterial aggregates distributed through the organs. Bacteriological exam isolated Salmonella spp. from the fragments of liver and spleen. The confirmation of the genus was made by serum agglutination on slide and by the polymerase chain reaction (PCR). The genetic sequencing identified the sample as Salmonella Typhimurium.

Ourinhos is situated in one of the major sugar cane producing regions in the State of São Paulo, where the manual harvesting is generally preceded by burning the foliage, resulting in large quantities of aerosols being emitted into the atmosphere. A one- month pilot study was executed during August 2010, to characterize the effects of those emissions on the atmosphere, considering the local circulation and the consequences for the region. The plumes were tracked by IPMet´s two S-band Doppler radars, also deploying a large range of meteorological, physical and chemistry instrumentation: a mobile Lidar with Raman channel to observe elevated layers and the type of aerosols, a medium-sized Sodar, as well as 6 Automatic Weather Stations spread through town. Various gases and particulates were also sampled, providing the atmospheric chemistry data base and thus documenting the impact on the region. This paper highlights a case study on 26 August, when a plume was tracked by TITAN Radar Software from the start of the fire, moving southwards at 14-17 km.h-1 with the winds at about 3,5 km above ground level, until it reached Ourinhos 2h15min later, where it was observed by the Raman Lidar and also detected by the aerosol and gas samplers. The high aerosol load of the atmosphere was confirmed by hourly mean values of AOD varying between 0,265 and 0,288 until 07:00 LT, after which they increased to 0,433 by 09:00 LT, as well as hourly mean backscatter profiles. Hourly values of the Lidar Ratio identified the aerosols as biomass burning products, also confirmed through the analysis of gas and aerosol samples simultaneously collected at the Lidar site.
