The aim of this study was to evaluate the effect of Dexamethasone (DXM) on clinical parameters, absolute and differential leukocyte count, specific IgG titers, IFN-γ production and parasitemia in beef calves seropositive to Neospora caninum. Fifteen calves were assigned to four experimental groups as follow: group A: 4 sero- positive calves treated with DXM; group B: 4 seropositive calves without DXM; group C: 3 seronegative calves treated with DXM, and group D: 4 seronegative calves without DXM treatment. The absolute leukocyte count was higher in both groups A and C in the 3rd day after the first dose of DXM mainly due to a significant neutrophilia (p0.05). Similarly, IFN-γ levels did not change among experimental groups (p>0.05). DNA was de- tected in calves from groups A and B at 7 Days Post Administra- tion (dpa) and from group A at 14 dpa. Even when DXM adminis- tration induced hemotological parameter changes, no reactivation of Neospora-infection was observed according to specific IgG titers and presence of the parasite on leukocytes in naturally seropositive beef male calves.

La infección por el virus orf, también conocida como ectima contagioso, es reconocida una zoonosis ocupacional. Se diagnostica por lesiones cutáneas que evolu cionan rápidamente desde máculas a pápulas, vesículas y pústulas. Se presenta el caso clínico de una estudiante de medicina veterinaria que había tenido contacto con caprinos, clínicamente sanos y sin lesiones aparentes, hacía 19 días. Presentó dos lesiones vesiculares que coalescieron hasta formar una lesión de mayor tamaño rodeada por un halo eritematoso. Las lesiones fueron compatibles con la presentación clásica de las producidas por el virus orf en humanos. Se confirmó la presencia del virus orf mediante una RPC anidada del tejido de biopsia. Es uno de los primeros casos confirmados mediante técnicas moleculares en seres humanos en Chile. Infection with the orf virus, also known as contagious ecthyma, is recognized as an occupational zoonosis worldwide. It is diagnosed by cutaneous lesions that progress rapidly from macules to papules, vesicles and pustules. The clinical case of a student of veterinary medicine who had had contact with goats, clinically healthy and without apparent lesions, which occured 19 days ago, is reported. She presented two vesicular lesions that coalesced to form a larger lesion surrounded by an erythematous halo. The lesions were compatible with the classical presentation of those produced by the orf virus in humans. The presence of the orf virus was confirmed by a nested PCR from biopsy tissue. It is one of the first cases confirmed by molecular techniques in humans in Chile. Fil: Flores, Carlos. Facultad de Ciencias Universidad Mayor; Chile Fil: Gonzalez Altamiranda, Erika Analia.

Bovine herpesvirus type 4 (BoHV-4) is a gamma-herpesvirus that has been isolated from apparently asymptomatic animals and from cattle with a variety of clinical signs. The pathogenic role of BoHV-4 remains unclear and it is unknown whether the virus acts as a primary pathogen or whether it facilitates secondary infections After natural or experimental infections, BoHV-4 can establish latency, mainly in cells of the monocyte/macrophage linage. Latent virus can be reactivated after glucocorticoid treatment or by stress factors. In 2007, BoHV-4 was isolated for the first time in Argentina, from samples of bovine abortions. In the present study, we used viral isolation, nested PCR and restriction endonuclease analysis (REA) to investigate the presence of BoHV-4 in bovine leukocytes from a single herd of dairy cattle with reproductive problems. In this work, we demonstrated that BoHV-4 genome is present in the leukocytes of a high proportion (63.4%) of animals, probably in a latent or persistent state. BoHV-4 was isolated from one out of eleven peripheral blood leukocyte (PBL) samples. By REA we demonstrated the existence of genomic variation among the strains circulating in this particular herd. Furthermore, all PBL samples evaluated in this study differed from the American prototype strain, DN 599. Overall, this work demonstrated that BoHV-4 is present in the leukocyte fraction of dairy cattle and that viral strains present in this herd are genetically divergent. Although BoHV-4 was detected in a herd with a background of reproductive disorders, it is not possible to conclude that the virus is the primary responsible for these conditions. O herpesvírus bovino tipo 4 (BoHV-4) é um gama-herpesvírus que foi isolado de animais aparentemente saudáveis e de gado com uma variedade de sinais clínicos. O papel patogênico do BoHV-4 ainda não está claro e não se sabe se o vírus age como um patógeno primário ou se facilita infecções secundárias. Depois de infecções naturais ou experimentais, BoHV-4 pode estabelecer latência, principalmente nas células dos linhagens de monócitos/macrófagos. O vírus latente pode ser reativado após o uso de glicocorticóides ou por fatores de estresse. Em 2007, o BoHV-4 foi isolado pela primeira vez na Argentina, a partir de amostras de abortos bovinos. No presente estudo, utilizou-se o isolamento viral, nested PCR e análise com endonucleases de restrição (REA) para investigar a presença de BoHV4 em leucócitos de bovinos provenientes de um único rebanho de gado leiteiro com problemas reprodutivos. Neste trabalho, demonstramos que o genoma do BoHV-4 está presente nos leucócitos em uma elevada proporção (63,4%) dos animais, provavelmente em um estado latente ou persistente. BoHV-4 foi isolado de uma de cada onze amostras de leucócitos no sangue periférico (PBL). Por REA nós demonstramos a existência de variações genômicas entre as estirpes circulantes deste rebanho particular. Além disso, todas as amostras de PBL avaliados neste estudo diferiram da estirpe protótipo Americano, DN 599. Em geral, este estudo demonstrou que o BoHV-4 está presente na fração leucocitária do gado leiteiro e que as estirpes virais presentes neste rebanho são geneticamente divergentes. Embora que BoHV-4 foi detectado em um rebanho com história de distúrbios reprodutivos, não é possível concluir que o vírus é o principal responsável por estas condições. Fil: Perez, Sandra.
