The present study indicates a strong astrocytic response, including the presence of many less differentiated vimentin-positive astrocytes and gitter cells positive for RCA-1 in severe lesions in the CNS of cats with FIP.

Sharp-force injuries are injuries caused by a mechanical force using sharp objects against the skin. Sharp-force injuries are mainly classified as stab, incised, chop, and therapeutic wounds and are less frequent than blunt-force injuries in animals. The analysis of the edges of the wound is crucial, especially if more than one type of lesion is involved. It may be difficult to differentiate between sharp trauma and blunt trauma, because lacerations can resemble incised wounds. The accurate documentation and examination of these injuries may indicate the instrument involved, the relationship between the animal and the perpetrator, and the force of the stab. Situations in which this type of trauma occurs may involve social violence, accidents, hunting, veterinary medical management, and religious rituals. The causes of death related to this type of trauma include hypovolemic shock, pneumothorax, or asphyxiation due to aspiration of blood. Necropsy findings should provide objective and unbiased information about the cause and manner of death to aid the investigation and further judgment of a possible crime.

Dexamethasone (DEX) is a corticoid hormone that is experimentally used to mimic the effects of increased levels of endogenous corticosterone observed during the stress response. Currently, stress is considered one of the major predisposing factors for diseases in the poultry industry. The aim of this study was to analyze the effects of DEX and/or of a 20-fold coccidial vaccine dose on leukocyte phenotypes in the spleen and cecal tonsils of chickens. Twenty specific-pathogen-free (SPF) Leghorn chickens were divided into four groups: a non-treated group (NT), a DEX-treated group (Dex), a vaccinated group (V) and a DEX-treated+vaccinated group (Dex+V). On experimental day (ED) 42, each bird in the vaccinated groups received a anti-coccidial vaccine. DEX was injected in the birds of the Dex and Dex+V groups (0.9 mg/kg) onED42 and ED45. + cells in the spleen of birds of the V group was higher than those measured in the other experimental groups. Our data suggest that CD4 + CD25 + cells and macrophages might be influenced by DEX treatment in spleen, but not in the cecal tonsils of chickens inoculated with Eimeria.

BackgroundTuberculosis is widely known as a progressive disease that affects endothermic animals, leading to death and/or economical losses, while mycobacterial infections in amphibians are commonly due to nontuberculous mycobacteria. To the authors’ knowledge, this report describes the first case of bovine tuberculosis in a poikilothermic animal.Case presentationAn adult female captive American bullfrog (Lithobates catesbeianus Shaw, 1802) died in a Brazilian aquarium. Multiple granulomas with acid-fast bacilli were observed in several organs. Identification of Mycobacterium bovis was accomplished by culture and PCR methods. The other animals from the same enclosure were euthanized, but no evidence of mycobacterial infection was observed.ConclusionsThe American bullfrog was introduced in several countries around the world as an alternative husbandry, and its production is purposed for zoological and aquarium collections, biomedical research, education, human consumption and pet market. The present report warns about an episode of bovine tuberculosis in an amphibian, therefore further studies are necessary to define this frog species’ role in the epidemiology of M. bovis.

Com o crescimento do mercado pet e suas inovações, proprietáriosde cães e gatos encontram cada vez mais alternativas paraa saúde e bem-estar de seus animais. Os estabelecimentos debanho e tosa vem ganhando espaço, uma vez que muitos proprietáriosnão dispõem de tempo e habilidade para a realizaçãoda higiene de seus animais. Porém, o que muitos proprietáriose até mesmo médicos veterinários desconhecem, é que cães egatos podem vir a óbito durante tais procedimentos aparentementeinofensivos, principalmente devido ao estresse. A mortedecorrente de estresse pode ocorrer tanto em animais debilitadosquanto saudáveis, independente da raça, idade ou sexo. Em umambiente de banho e tosa, a presença de agentes estressores éinevitável, mas algumas regras devem ser seguidas a fim de minimizaro estresse nestes animais. Este trabalho tem como objetivofornecer informações acerca da causa de morte nessas circunstânciase suas implicações legais.
