The organization of flash electroretinography unit in Veterinary Medicine Ciência Rural
Honsho,Cristiane dos Santos; Oriá,Arianne Pontes; Lazaro Júnior,Luiz Paulo da Veiga Monteiro; Dorea Neto,Francisco; Laus,José Luiz.
Electroretinography is the technique that allows the evaluation of changes in electrical potential that occur when the eye is stimulated by light. Such changes reflect the response of several retinal cells including photoreceptors (cones and rods). Thus it evaluates the retinal functionality and can diagnose abnormalities in retinas seem to be normal by ophthalmoscopy. Due to the constant evolution in veterinary ophthalmology, new centers of retinal electrophysiology have been introduced around the world either for early diagnosis of retinopathies or for preoperative evaluation of animals with cataracts and glaucoma, as well as for continuing research. The Ophthalmology Unit of the "Governador Laudo Natel" Veterinary Teaching Hospital, in the Faculty of...

Anatomo-pathological and epidemiological analysis of urinary tract lesions in dogs Ciência Rural
Sapin,Carolina da Fonseca; Silva-Mariano,Luisa Cerqueira; Bassi,Jordana Nunes; Grecco,Fabiane Borelli.
ABSTRACT: In dogs, diseases of the urinary tract are common and can be caused by disorders of varied etiology. The objective of this study was to classify qualitatively and quantitatively urinary tract lesions of 363 dogs, which were classified according to its anatomical distribution and etiology. The data was obtained from the revision of 36 years of protocols from the Regional Laboratory of Diagnosis (LRD/UFPel) and it represents 4.0% of diagnoses from a total of 8980 for that period and species. Renal injury accounted for 93.1% of cases, with 309 being primary kidney lesions; from which the main lesions were the tubulointerstitial nephritis (142 cases) often associated with Leptospirosis (47). Injuries of lower urinary tract accounted for 6.9% of the...

Botulism in non-ruminants in Brazil Ciência Rural
Oliveira Júnior,Carlos Augusto de; Silva,Rodrigo Otávio Silveira; Olinda,Roberio Gomes; Lobato,Francisco Carlos Faria.
ABSTRACT: Botulism is an intoxication caused by the ingestion of neurotoxins secreted by Clostridium botulinum and characterized by progressive flaccid symmetrical paralysis. Among non-ruminant animals, avian species and dogs are the most commonly affected by botulism, while horses and pigs are less-commonly diagnosed with the disease. Despite the importance of this disease in animals, the Brazilian literature only includes case studies and outbreak descriptions. The aim of this study was to review the main features and to provide recent data on the occurrence of botulism in non-ruminants in Brazil.

Physical-chemical analysis of the cerebrospinal fluid of healthy dogs submitted to different storage periods and temperatures Ciência Rural
Rosato,Paula Nunes; Gama,Fernanda Gomes Velasque; Santana,Aureo Evangelista.
Disorders involving the nervous system have a great importance in veterinary medicine because they have a high incidence and few auxiliary tools for their diagnostic, prognostic and evaluation of the employed therapy. Today, the diagnostic is based, mainly, on the patient history and neurologic examination. Hence, evaluation of the cerebrospinal fluid elements is one of the few alternatives to clinically access the central nervous system (CNS). Even with the great usefullness of the physical-chemical and cytoscopy exams of the CSF in veterinary neurology, there are few studies concerning the stability of its elements under freezing storage. The present study was aimed at verifing the influence of temperature and period of conservation on physical-chemical...

Hemodynamic gestational adaptation in bitches Ciência Rural
Almeida,Vívian Tavares de; Uscategui,Ricardo Andres Ramirez; Silva,Priscila Del Aguila da; Avante,Michele Lopes; Simões,Ana Paula Rodrigues; Vicente,Wilter Ricardo Russiano.
ABSTRACT: Throughout pregnancy, maternal hemodynamic adaptation is needed to ensure proper uterine perfusion and fetal development. When the uteroplacental vascular system is formed, starting with reduced resistance to uterine arterial flow, this results in decreased total vascular resistance, an activation of neuroendocrine vasoactive peptides, an increase in circulating blood and changes in the cardiovascular system morphophysiology to respond to the increasing demands of uterine perfusion. There has been considerable study of hemodynamic adaptation in pregnant women and this assessment has become a diagnostic tool for fatal obstetric disorders. However, in bitches the available information in this regard is limited; therefore a parallel was drawn...

Carciofi,Aulus Cavalieri; Gonçalves,Karina Nogueira Venturelli; Vasconcellos,Ricardo Souza; Bazolli,Rodrigo Sousa; Brunetto,Márcio Antonio; Prada,Flávio.
The success of a weight loss program for pets depends on the owners collaboration. Their compliance is fundamental in establishing the correct food management. The objective of this study was to compare the effectiveness of a weight loss program in two groups of dogs, one maintained under experimental conditions and the other with their owners. The same hypocaloric food was used to feed all animals, the amount being restricted to 60% of the estimated maintenance energy requirement for a 15% reduction of the present body weight of the dog. The animals were followed during 90 days. A standard questionnaire was used to study the owners' perception of obesity and its treatment. The protocol and the diet were found to be effective. The control dogs had an...

Transmission routes of visceral leishmaniasis in mammals Ciência Rural
Oliveira,Vinícius Vasconcelos Gomes de; Alves,Leucio Câmara; Silva Junior,Valdemiro Amaro da.
Visceral leishmaniasis (VL) is a chronic disease caused by Leishmania infantum. The major sites of parasite localization in infected animals are the secondary lymphoid organs, bone marrow and cutaneous tissue. However, reports exist on the detection of the parasite in the organs of the male and female genital system. The main route of transmission is related to the hematophagous sandfly vectors of the genus Lutzomyia(New World) and Phlebotomus(Old World). However, other routes of transmission may be mentioned, such as sexual, vertical, hematogenic without vector and others involved in VL epidemiology. Thus, the current article reviews the main forms of transmission of visceral leishmaniasis in mammals

Development and evaluation of mosapride citrate orally disintegrating tablets for dogs Ciência Rural
Yi,Tingting.
ABSTRACT: The purpose of the study was to prepare orally disintegrating tablets (ODTs) of mosapride citrate for dogs with fast disintegration and low cost. The ODTs were developed by varying the components and the ratio of excipients. A direct compression method was used. The properties of the ODTs, including hardness, friability, active ingredient content, and in vitro disintegration time, were investigated, and an economic analysis of the formulations was performed. For all formulations, friability was less than 1%, and the hardness varied from 37.69±4.08 to 48.73±5.62 N, which indicated that the tablets had sufficient mechanical integrity to withstand packaging and carrying. Results showed that Formulation (F) 2, containing 5% sodium carboxymethyl...

Clostridium difficile infection: main features and occurrence in domestic species in Brazil Ciência Rural
Silva,Rodrigo Otávio Silveira; Guedes,Roberto Maurício de Carvalho; Lobato,Francisco Carlos Faria.
Clostridium difficile is an emerging enteropathogen of humans and domestic animals. The bacterium was recently confirmed to be present in foals and dogs in Brazil, with some recent studies suggesting that C. difficile is one of the most important causes of piglet diarrhea in the country. Moreover, some reports also suggest the transmission of this microorganism between animals and humans, raising the possibility that C. difficile is a zoonotic disease. Therefore, the aim of the present review is to describe the main features of C. difficile infection in domestic animals and outline the occurrence of the disease in horses, dogs and pigs in Brazil.

Coura,Fernanda Morcatti; Diniz,Amanda Nadia; Oliveira Junior,Carlos Augusto; Lage,Andrey Pereira; Lobato,Francisco Carlos Faria; Heinemann,Marcos Bryan; Silva,Rodrigo Otávio Silveira.
ABSTRACT: This study identified the virulence genes, pathovars, and phylogenetic groups of Escherichia coli strains obtained from the feces of dogs with and without diarrhea. Virulence genes and phylogenetic group identification were studied using polymerase chain reaction. Thirty-seven E. coli isolates were positive for at least one virulence factor gene. Twenty-one (57.8%) of the positive isolates were isolated from diarrheal feces and sixteen (43.2%) were from the feces of non-diarrheic dogs. Enteropathogenic E. coli (EPEC) were the most frequently (62.2%) detected pathovar in dog feces and were mainly from phylogroup B1 and E. Necrotoxigenic E. coli were detected in 16.2% of the virulence-positive isolates and these contained the cytotoxic necrotizing...

Effects of meloxicam administered by different routes to control experimental uveitis in dogs Ciência Rural
Ribeiro,Alexandre Pinto; Escobar,André; Motheo,Tathiana Fergunson; Godoy,Guilherme Selera; Laus,José Luiz.
Efficacy of meloxicam, administered by different routes was studied in experimental uveitis in dogs. Anterior chamber paracenteses was accomplished at two different moments (M0 and M1), with a five hour interval among them. At M0 and M1, 0.2mL of aqueous humor was collected and total protein and prostaglandin E2 (PGE2) quantitation was determined. Four groups were formed (n=5), which received meloxicam at the end of M0. by the following routes: subcutaneous (GIm), subconjunctival (GII), and topical (GIII). A fourth group that received no treatment was instituted (Control). Conjunctival histopathology of the GII was performed. Results were evaluated statistically (P≤0.05). In all groups, protein and PGE2 values enhanced significantly in M1. Protein and PGE2...
