Canine distemper is caused by the canine distemper virus (CDV), a paramyxovirus of the genus Morbillivirus, with a worldwide distribution. Canine distemper is a multisystem disease, potentially fatal. Affected organisms may develop clinical or subclinical infections, among them respiratory, gastrointestinal and of the nervous system. In the present work, we use a veterinary pharmaceutical composition of silver nanoparticles (AgNPs) for the treatment of distemper in dogs with neurological and nonneurological symptoms. AgNPs treatment of animals with non-neurological distemper provides a very high rate of recovery without sequelae. However, in dogs with neurological symptoms, AgNPs treatment was not able to reverse the disease. © 2016 Inderscience Enterprises Ltd. Source

The aim of this study was to evaluate the toxicity of Stryphnodendron fissuratum pods in Guinea pigs (Cavia porcellus) and test the hypothesis that this plant has teratogenic effects. Thus, sixteen Guinea pigs were randomly divided into four groups of four animals each. Groups 10, 20 and 40 consisted of Guinea pigs that received commercial food that contained crushed pods of S. fissuratum at concentrations of 10, 20 and 40 g/kg, respectively, during the period of organogenesis. Control group consisted of Guinea pigs under the same management conditions that did not receive crushed pods of S. fissuratum in their food. In all experimental groups, the main clinical signs of poisoning consisted of anorexia, prostration, absence of vocalizations, alopecia, diarrhea, and abortions within the adult Guinea pigs. Those that did not abort gave birth to weak, malnourished pups, some of which had fetal malformations. The main teratogenic changes consisted of eventration, arthrogryposis, amelia of the forelimbs, anophthalmia, microphthalmia, anotia and agnathia. The reductions in the number of offspring and the malformations observed in the experimental groups suggest that S. fissuratum affects fetal development and is teratogenic. © 2015 Elsevier Ltd.A all rights reserved.

Toxoplasma gondii, obligate intracellular parasite, like in other species, is very common in dogs. Its diagnosis is difficult because the clinical signs that can be confused with other illnesses. The use of PCR in diagnosis has been growing and has helped in the detection of the parasite at different stages of the disease. We collected blood samples from dogs in the city of Cuiabá and subjected to molecular analysis for the detection of DNA of T. gondii. These data were related to the intake of raw meat of these animals. The result showed that 17,5% had a diet associated with raw meat, but only 12,7% were positive by PCR. The intake of raw foods and undercooked is a route of infection that must be highlighted by having a zoonotic and highly relevant to public health. Source

It is reported the case of a dog with strangury, increased bladder volume and presence of a painless mass in the region of penis bone. The failure of urethral probing allowed the diagnosis of urinary obstruction. A regular contour mass, moving and obstructing the urethra, was observed in the radiographic examination. After surgical removal, the tissue was submitted to histopathologic analysis, which confirmed the diagnosis of aneurismal cyst of the penis - yet unreported disease in dogs. Source

The aim of this research was to identify the occurrence of pathogens causing subclinical mastitis in grade B milk farms of the Jaguapitã county, state of Paraná, Brazil. California Mastitis Test (CMT) were carried out in 400 milk samples from 100 animals and 157 teats from 55 animals (55%) were positive, showed score two or higher to CMT. When these 157 positive samples to CMT were transported for bacterial culture in blood agar, 25.48% (40/157) samples showed no bacterial growth or more than two types of bacterial colonies grew, 28.03% (44/157) were Coagulase-negative staphylococci (CNS), 8.28% (13/157) were Streptococcus uberis, 7.64% (12/157) were Staphylococcus aureus, 7.64% (12/157) were Corynebacterium spp, 7.01% (11/157) were Staphylococcus intermedius, 4.46% (7/157) were Staphylococcus hyicus, 3.82% (6/157) were Bacillus spp., 2.55% (4/157) were Streptococcus dysgalacteae, Enterobacteria and Yeasts. We conclude that CNS is the most relevant subclinical mastitis causative agent. Source
