Etiology of canine otitis media and antimicrobial susceptibility of coagulase-positive Staphylococci in Fortaleza city, Brazil

O presente trabalho avaliou a microbiota do ouvido medio e os perfis de susceptibilidade a antimicrobianos de cepas isoladas de caes com otite media. Um total de 62 caes obtidos no Centro de Controle de Zoonoses de Fortaleza Ceara / Brasil foram estudados no periodo de 10 meses (agosto/2003 a junho/2004). Do total de animais, 46.8% (n=30) foram positivos para otite media e a infeccao envolvida era monomicrobiana em 76,6% dos casos. Os agentes isolados com maior frequencia foram Staphylococcus coagulase-positiva (CPS-55%) e Pseudomonas sp (10%). Considerando-se S. intermedius (n=13) e S. aureus subsp aureus (n=9), respectivamente, as mais elevadas taxas resistencia foram observadas frente a: penicilina G (30,76% e 44,44%), ampicilina (7,69% e 44,44%), eritromicina (23,07% e 44,44%), clindamicina (23,07% e 44,44%) e trimetropim/sulfametoxazol (15,38% e 33,33%).

Avaliações ultrassonográfica e radiográfica dos efeitos da suplementação com dois tipos de probióticos sobre o intestino de cães filhotes

The effects of supplementation with types of probiotics for beagle puppies that received high and low quality diets on the findings of imaging techniques were evaluaded. Eighteen animals were distributed in three randomized treatments: 1, control (diet), 2, diet with a probiotic (Bifidobacterium), and 3, diet with another probiotic (Lactobacillus). The experiment was divided into two phases each characterized by a change of diet. By ultrasonography, the thickness of the gastrointestinal wall was evaluated as well the presence of gas in the bowel and thickening of the wall by radiography. There was an increase in the thickness of the intestinal wall (P 0.05) were observed among treatments for scores of intestinal gas. The quantitative analysis allowed the determination of a score of intestinal gas, noninvasively, using the software Image J ®. It was concluded that the imaging technique supports the recommendation of this method as an auxiliary tool in nutritional assessment of diets for dogs.

Doença renal medular cística em uma cadela Yorkshire Terrier: relato de caso

A Yorkshire Terrier bitch presented hematemesis, abdominal distention, poliuria, and polidipsia. After clinical examination, it was established a clinical suspect of nephropathy. The complementary exams showed normochromic and normocytic anemia and serum concentrations of ureia (306mg/dl) and creatinine (3.6mg/dl) above the references values. At two-dimensional ultrasound hipoechoic and anechoic cystic areas were observed, as well as hiperechogenic renal pattern and corticomedullary ratio loss. At necropsy, the medullary region presented many small cysts in a fibrous connective tissue. Cortical tubulointesticial lesion was responsible to the resulting renal failure. It was established a tubulointersticial nephritis diagnosis.

Avaliação ultrassonográfica da anomalia vascular portossistêmica em cão: relato de caso

It was reported the ultrasonographic evaluation, assisted to Doppler color, of the portosystemic vascular anomaly in a Poodle Toy dog. The dog was referred with lung edema and gastrointestinal alterations. At ultrasonographic exam, portal vessels were extended and tortuous. These findings associated to clinical and laboratorial findings, allowed to identify the vascular portosystemic anomaly in the patient.

Efeitos da parede de levedura em dieta úmida na microbiota fecal, na produção de gás e na morfologia intestinal de gatos adultos

The aim of this study is to evaluate the effects of yeast extract (EPL) in the moist diet on the fecal microbiotal, gas production and intestinal morphology of adult cats. Twenty adult cats from both sexes were randomly assigned to four treatments: 1) moist commercial diet (control); 2) control + 0,2% yeast extract dry matter; 3) control + 0,4%; and 4) control + 0,6%. Fecal microbiology and intestinal morphology were performed by radiographic, ultrasound, colonoscopy and intestinal biopsy exams for histology. There were no significant differences (P>0,05) for lactic acid bacteria counts and clostridium-reductor, gas area in the bowel (radiographic), wall thickness of the colon (ultrasound) and colonocytes count/globet cells (histology). Through colonoscopy, changes in characteristics of the intestinal mucosa in animals receiving treatment 4 were noticed. It is concluded that the addition of up to 0.6% EPL had no effect on the parameters evaluated, but further studies are needed to understand the action mechanisms and additive effects for domestic cats.

Efeitos colaterais da ranitidina aplicada em dose terapêutica em cães saudáveis

The purpose of this study was to verify if the ranitidine dosage of 2mg kg-1 by intravenous path causes emesis or hypotension in healthy dogs. They were selected 10 Labrador Retriever, 10 Beagles and 10 mongrel dogs, five animals of each sex. The animals were submitted to clinical examination and blood pressure evaluation before ranitidine administration and also 10 minutes and 4 hours after administration of it. After administration was observed that 13.3% of the animals presented normal; 6.7% of the dogs presented apathy; 50% of the animals presented salivation and 30% presented apathy, salivation, emesis mimic or emesis. There was no significative arterial blood pressure decrease after ranitidine administration. It was concluded that ranitidine useful in therapeutic dosage by intravenous path may provoke apathy, salivation, emesis mimic and emesis.

Radiografia intraoral e convencional da hemiarcada superior direita de gatos domésticos

ABSTRACT The aim of this research was to evaluate the right maxilla hemiarcade of cats through parallel dental radiographic techniques, applying Han Shin intraoral film positioner. Images obtained with this method were correlated with conventional radiographic techniques (extraoral). The goal was to establish the advantages and disadvantages to detect possible dental and periodontal diseases. Thirty mixed breed cats were evaluated, 17 males and 13 females, ages one to three years old, confined in catteries in the Department of Zootecnia of the Federal University of Lavras/MG. Radiographies of the right maxilla were taken with the animals under general anesthesia, and three incisors, one canine, three premolars and one molar teeth were included in the intraoral and extraoral images. The radiographic images were analyzed and a qualitative comparison of pairs of intraoral and conventional images from the same animals was achieved. To establish the dental image procedures that were better adapted for cats, the McNemar Test (Modified Qui-Square) was used for statistical

Aspectos radiográficos de condrodistrofia felina

ABSTRACT Congenital, hereditary, and developmental diseases are common in small animals radiology. Chondrodystrophy is characterized to osteoarticular angular deformities. The aim of this study is to relate a case of feline chondrodystrophy, alteration uncommon in this species. The animal presented bone alterations in limbs, without healthy commitment at clinical examination. At radiographic evaluation, bone angulation was altered in long bones with articulation enlargement. It was concluded that, even uncommon in felines, chondrodystrophy may be an incidental radiographic finding, but with importance to epidemiologic aspect of this disease.
