Malassezia pachydermatis: enzymes production in isolates from external ear canal of dogs with and without otitis Arq. Bras. Med. Vet. Zootec.
Coutinho,S.D.A..
The relationship between production of enzymes and pathogenicity of Malassezia pachydermatis strains was studied. Thirty strains of M. pachydermatis isolated from dogs were used: 15 originating from animals with external otitis and 15 obtained from ears of asymptomatic dogs. The samples, obtained by introduction of a sterile swab into the auditory canal after cleaning the auricle with alcohol-ether solution, were seeded onto Sabouraud dextrose agar with chloramphenicol (100mg/l) and were incubated at 37°C for up to two weeks. The colonies were identified according to their macro-and-micromorphology. All strains were investigated for the production of chondroitin-sulphatase, hyaluronidase, phospholipase and proteinase. Most of the strains showed a high...

Management of venomous snakebites in dogs and cats in Brazil J. Venom. Anim. Toxins incl. Trop. Dis.
Ferreira Júnior,R.S.; Barravieira,B..
Snake envenoming is a major problem both to veterinary and human medicine in tropical countries due to high incidence, severity, and sequelae. In Brazil, most envenomings involving animals are caused by Bothrops and Crotalus snakes; these are the highest risk to animals. This study reports on Bothrops and Crotalus envenomings in dogs, the main species responsible for epidemiology, pathogenesis, venom action, clinical signs, sequelae and complications, clinical pathology, necropsy findings, diagnosis, and treatment. Veterinarians must be capable of identifying the snake not only by observing its characteristics but also symptom evolution.

Brito,F.L.C.; Silva Júnior,V.A.; Maia,F.C.L.; Pereira Junior,J.R.; Laus,J.L..
Keratoconjunctivitis sicca is characterized by qualitative or quantitative abnormalities in the aqueous component of the tear film and is frequent in dogs with distemper. Twenty-eight third eyelid glands of end-stage dogs that died from distemper were analyzed by light microscopy. Keratoconjunctivitis sicca was diagnosed based on ophthalmic findings regarding alterations in the ocular surface and by the Schirmer tear test. The excised glands were fixed in 10% buffered formalin and processed for embedding in paraffin. The blocks were cut into 4µm sections and the sections were stained with hematoxylin-eosin and Masson's trichrome. Analysis revealed tubuloacinar gland atrophy, thickening of connective tissue, and mild to intense inflammatory exudation mainly...

MicroRNA and cancer: a focus on mammary tumors in female dogs Ciência Rural
Salvador-Bernabé,Rosana Lino; Tinucci-Costa,Mirela; Amorim,Renee Laufer.
ABSTRACT: Mammary tumors are the most frequent tumors reported in female dogs and have great relevance in veterinary oncology; however, little is known about the molecular mechanisms involved in the development of metastasis. An increasing number of human studies have suggested that epigenetic alterations, such as DNA methylation, miRNA, and histone modifications, are the predominant events leading to the metastatic phenotype in tumor cells and participate in regulating oncogenic signals associated with tumor spread. Among these epigenetic alterations, miRNAs have stood out in recent years, presenting a fundamental role in tumorigenesis. There are still few studies evaluating the role of miRNAs in canine mammary tissues. Thus, this paper aims to review...

Modified extracapsular extraction versus endocapsular phacoemulsification: intraoperative and immediate postoperative events Arq. Bras. Med. Vet. Zootec.
Honsho,C.S.; Oriá,A.P.; Pigatto,J.A.T.; Laus,J.L..
The clinical events and variations in intraocular pressure (IOP) that occur in endocapsular phacoemulsification technique were compared to the modified extracapsular extraction technique during the intraoperative and immediate postoperative periods. Phacoemulsification technique caused less corneal edema, less ocular discomfort and fewer postoperative complications than the modified extracapsular extraction technique. The observed increase in postoperative IOP, especially in the case of phacoemulsification, makes pressure monitoring mandatory, as well as the use of ocular hypotensive agents when the IOP exceeds acceptable limits.

Castilho,J.G.; Brandão,P.E.; Carnieli Jr,P.; Oliveira,R.N.; Macedo,C.I.; Peixoto,Z.M.P.; Carrieri,M.L.; Kotait,I..
Eleven central-nervous-system samples collected from stray dogs between 2000 and 2004 were found positive by RT-PCR, which amplified a 480bp fragment of the N gene of canine distemper virus (CDV). Phylogenetic analysis based on partial N-gene sequences showed four major clusters. All dog strains segregated into cluster I, with a mean nucleotide identity of 95.8% and 95.6% with the Onderstepoort and Lederle vaccine strains, respectively. Cluster II contained all the raccoon-related strains, cluster III Orient strains and Cluster IV the Onderstepoort and Lederle vaccine strains, with a mean nucleotide identity of 99.7% between them. This is the first report of phylogenetic analysis of CDV strains in Brazil.

Molecular evidence of early vertical transmission of Leishmania ( Leishmania ) infantum in a dog Ciência Rural
Oliveira,Vinícius Vasconcelos Gomes de; Ramos,Rafael Antonio Nascimento; Ramos,Carlos Alberto do Nascimento; Guerra,Neurisvan Ramos; Maia,Frederico Celso Lyra; Alves,Leucio Câmara; Silva Junior,Valdemiro Amaro da.
ABSTRACT: Visceral leishmaniasis (VL) is caused by the protozoon Leishmania infantum . Transmission of this parasite to hosts occurs mainly through the bite of infected sand flies. However, alternative infection routes have been hypothesized, especially in areas where the biological vector is absent. The exact time of infection and whether in utero transmission occurs have still not been fully elucidated. This report demonstrates molecular evidence of vertical transmission of L. infantum from a pregnant dog to the embryo. Samples (e.g. vulva, vagina, cervix, uterine body, uterine horn and ovaries) from a female naturally infected by L. infantum and from her embryo were molecularly analyzed by means of qPCR and cPCR followed by DNA sequencing. The...

Morphological Features of the Apical Region in the Principal Cells of Mongrel Dog Epididymis International Journal of Morphology
Schimming,Bruno Cesar; Vicentini,Carlos Alberto.
The epithelial principal cells are the predominant cell type of the epididymis. These cells have been shown to be both secretory and endocytic cells. The apical region of the cytoplasm of principal cells in the mongrel dog are located close to the cell apex and tubular lumen, and shown microvilli at the luminal border and present a endocytic apparatus, that consists of coated pits and vesicles, endosomes of varying size, multivesicular bodies, and lysosomes. The endosomes, multivesicular bodies and lysosomes contained the electron-dense patches. These results suggest that principal cells of the epididymis in the dog as possess a highly developed endocytic apparatus play a role in endocytosis. These cells function are similarly to the related in other...

Morphometric and quantitative characterization of atrial ganglion neurons from the intercaval region in dogs with dilated cardiomyopathy Arq. Bras. Med. Vet. Zootec.
Camacho,A.A.; Oliveira-Alves,R.; Klein,R.P.; Sousa,M.G..
The quantity, morphometry, and quality of atrial neurons from the intercaval region in dogs with dilated cardiomyopathy (DCM) were evaluated. Dogs with DCM had greater ganglion neurons than control dogs. The histologic evaluation of the ventricular myocardium and ganglion neurons confirmed DCM and showed the degeneration of ganglion neurons. Dogs with chronic DCM had a secondary cardioneuropathy owing to impaired parasympathetic neural control.

Non-contact specular microscopy in aphakic and pseudophakic dogs Ciência Rural
Nagatsuyu,Claudia Emi; Abreu,Priscila Barreto de; Kobashigawa,Karina Kamachi; Conceição,Luciano Fernandes da; Morales,Adriana; Andrade,Alexandre Lima de; Padua,Ivan Ricardo Martinez; Martins,Bianca da Costa; Laus,José Luiz.
Cataract is one of the most common ocular diseases in dogs, and phacoemulsification is considered its treatment of choice. Posterior capsular opacity (PCO) is a frequent complication and may occur weeks or months after the surgery. It is known that intraocular lenses (IOL) used for the correction of post-operative hypermetropia are an adjunctive aid in the prevention of PCOs, mainly the foldable acrylics designs with square and truncated edges. However, IOL placement may result in endothelial cell loss. This study evaluated the morphology and cellularity of the endothelium by non-contact specular microscopy in aphakic and pseudophakic dogs. Endothelial cell density, endothelial cell area, coefficient of variation and hexagonal cells percent were analyzed...
