This report describes a case of fatal aspergillosis caused by A. fumigatus during the recovery of an oiled Magallanic penguin. The possible role of aspergillosis as a possible complication responsible for the mortality of penguins surviving the first days of treatment for oil is emphasized.
African swine fever (ASF) is a viral hemorrhagic disease with different clinical and lesional changes depending of virulence of strains/isolates and immunological status of pigs. In acute and subacute forms of ASF, severe vascular changes are present, with hemorrhages in different organs (mainly melena, epistaxis, erythema, renal petechiaes and diffuse(More)
Duck virus enteritis is an acute contagious viral disease affecting birds of the order Anseriformes (ducks, geese and swans). The disease agent is a member of the Herpesviridae family (Anatidae herpes virus 1). A group of Anseriformes waterfowl from a Nature Reserve and Centre for the Recovery of Endangered Species in Spain suffered an outbreak of the(More)
Twenty-one pigs inoculated with a highly virulent isolate (E70) of African swine fever (ASF) virus were killed 1-7 days later; a further three animals served as uninfected controls. An early increase in TNF-alpha, IL-1alpha, IL-1beta and IL-6 expression was detected in lymphoid organs from infected animals, together with an increase in the serum(More)
To gain further insight into the pathogenesis of African swine fever (ASF), the cytokine expression by macrophages in spleen and lymph nodes were examined. Twenty-one piglets were inoculated with the highly virulent isolate Spain-70 of ASF virus and killed in groups at 1-7 post-inoculation days (pid). An increase in the immunohistochemical detection of(More)
OBJECTIVE To determine serum concentrations of the selected acute-phase proteins (APPs) haptoglobin, serum amyloid A (SAA), and C-reactive protein (CRP) in pigs experimentally inoculated with classical swine fever (CSF) and African swine fever (ASF) viruses. ANIMALS 8 crossbred (Large White x Landrace) 10-week-old pigs. PROCEDURES Pigs were allocated to(More)
This paper report on the lesions occurred in the thymus in experimental acute African swine fever (ASF). Twenty-one pigs were inoculated with the highly virulent ASF virus (ASFV) isolate Spain-70. Animals were slaughtered from 1 to 7 days post infection (dpi). Three animals with similar features were used as controls. Thymus samples were fixed in 10%(More)
Thirty-two Large White x Landrace pigs, 4 months old, were inoculated with the classical swine fever (CSF) or hog cholera virus strain "Alfort" in order to identify the mechanism responsible for the lymphopenia and thrombocytopenia observed in the spleen during the experimental induction of disease, by immunohistochemical and ultrastructural techniques.(More)
Atrophy of the thymic cortex and loss of thymocytes were studied in 32 pigs inoculated with the virulent strain "Alfort" of classical swine fever (CSF) virus and killed at intervals from 2 to 15 days after infection. Immunohistochemical, ultrastructural, ELISA and TUNEL methods were used. The results suggested that direct action of CSF virus on thymocytes(More)
The aim of this study was to report on the lesions occurring in the intestine during experimental classical swine fever (CSF) and to clarify the nature of infected cells and the distribution of viral antigen. Thirty-two pigs were inoculated with the virulent CSF virus (CSFV) isolate Alfort 187 and slaughtered from 2 to 15 postinoculation days; four animals(More)
