Serum and liver iron concentration in dogs with experimentally induced hepatopathy.

Background And Aim: Iron (Fe) status is altered in human and experimental animal hepatopathies. In dogs limited data are available. The aim of this study was to investigate serum iron (SI), total iron binding capacity (TIBC), percentage transferrin saturation (SAT) and Fe status in the liver of dogs with experimentally induced hepatopathy.

Cellular immunophenotyping of exfoliative dermatitis in canine leishmaniosis (Leishmania infantum).

Lymphocyte subsets, major histocompatibility complex (MHC)-II expressing cells and number of amastigotes in the epidermis and dermis were investigated immunohistochemically in 48 dogs with patent leishmaniosis, with or without exfoliative dermatitis (ED) to study the immunopathogenesis of this common cutaneous form of the disease. Skin biopsies were obtained and compared for ED sites (group A, n = 26), normal-appearing skin from the same animals (group B, n = 24), and leishmanial dogs not exhibiting ED (group C, n = 22), and normal controls (group D, n = 22). The CD3+, CD45RA+, CD4+, CD8+ (CD8a+), CD21+, and MHC-II+ cells and leishmania amastigotes were identified immunohistochemically and counted with the aid of an image analysis system.

Equine infectious anemia in mules: virus isolation and pathogenicity studies.

There appears to be a lack of information concerning responses of mules to natural infection or experimental inoculation with equine infectious anemia virus (EIAV). In the present study EIAV was isolated from mules, for the first time, and its pathogenicity in naturally infected and experimentally inoculated animals was investigated. Two naturally infected (A and B) and three EIAV free mules (C, D and E) were used for this purpose.

Field study on the efficacy of two different vaccination schedules with HYORESP in a Mycoplasma hyopneumoniae-infected commercial pig unit.

A trial was carried out with HYORESP a Mycoplasma hyopneumoniae (M. hyo) vaccine in order to confirm the benefit of vaccination under field conditions in a commercial industrial farrow-to-finish unit, contaminated with M. hyo.
