Perfil de sensibilidade e multirresistência em linhagens de Escherichia coli isoladas de infecção do trato urinário, de piometra e de fezes de cães

Susceptibility profile and multiple drug resistance in 158 E. coli strains isolated from urinary tract infection (UTI), pyometra, and feces of dogs were studied. Norfloxacin, ciprofloxacin, and enrofloxacin were the most-effective drugs (>60%) for E. coli strains. High rates of resistance to antimicrobials were observed in 60% or more of the isolated strains using sulfametoxazole/trimetoprim. Multiple drug resistance for three or more antimicrobials was observed in two (47.1%) strains isolated from UTI, seven (13.5%) from pyometra, and four (7.3%) from feces. From these, 17 (33.3%), one (1.9%), and three (5.5%), respectively, showed multiple resistance to five or more drugs.

Estudo retrospectivo de ovariossalpingo-histerectomia em cadelas e gatas atendidas em Hospital Veterinário Escola no período de um ano

Realizou-se um estudo retrospectivo das indicações de ovariossalpingo-histerectomia - eletiva e terapêutica - no período de um ano. Foram analisados 193 prontuários de cadelas e gatas atendidas em Hospital Veterinário Escola, entre março de 2010 e março de 2011, levando em consideração a espécie, a idade e o uso ou não de anticoncepcional. Constatou-se que a demanda de OSH com caráter terapêutico (78,8%) é consideravelmente mais alta que a eletiva (21,2%). Observou-se que as anormalidades reprodutivas detectadas com maior frequência foram piometra (53,36%) e complicações obstétricas (25,38%) e que o uso de anticoncepcional foi o fator relevante para o delineamento desses quadros.

Ultrassonografia Doppler na avaliação renal de cadelas diagnosticadas com piometra antes e após tratamento com ovariosalpingohisterectomia

The aim of this study was evaluate the renal hemodynamics of bitches with pyometra by means of laboratory tests, ultrasound B mode and Doppler, before and after treatment with ovariohysterectomy (OSH). This study evaluated 30 bitches with pyometra, all were subjected to OSH (moment 1) and 20 were evaluated after 7 days (moment 2). The renal perfusion, the resistivity index (RI) of the main renal artery and the interlobar arteries (cranial, middle and caudal) were statistically different between times 1 and 2 (p<0,05). There was no statistical difference for renal perfusion between the left and the right kidney at the time 1 and 2. The correlations between the IR of the main artery and the variables used to determine renal function were stablished at the time 1. For the correlated variables: urea, creatinine, proteinuria, ratio GGT/creatinine and protein/creatinine were curvilinear and positive associations with the resistivity index of the main renal artery (p<0,05), however these correlations were considered medium and weak. Comparing the RI of the main renal artery with different scores of dehydration and renal perfusion, there was statistical difference, and show increased of resistance renal in bitches with moderate reduction in renal perfusion as well as in dehydrated bitches. Were evaluated several features of renal morphology in ultrasound B mode, however, only the presence of pelvic dilatation, medullary signal and other changes as infarcts areas and diffuse hyperechoic spots in the renal cortical and medullary were statistically different from one moment to the other, most frequently at the time 2. The results of this study show that the Doppler ultrasound can identify changes of reduction in renal perfusion by color Doppler and the increasing of the resistivity index of the renal arteries in some bitches with pyometra. As well as, the ultrasound B mode, although has non-specific changes, can detect progressive renal disorders in bitches with pyometra.

Exames laboratoriais importantes no diagnóstico da Piometra canina

Canine Pyometra is a uterine disease that occurs in sexually mature bitches, with higher incidence in nulliparous and animals over 4 years and is characterized by presenting an accumulation of pus in the uterine lumen, usually occurring in diestrus. Laboratory tests are important tools for the detection of metabolic abnormalities associated with sepsis and renal function, which are serious consequences of pyometra. In blood the main findings are normochromic non-regenerative anemia, presence of dehydration, and sometimes thrombocytopenia. The WBC count may be normal but most often occurs a neutrophilic leukocytosis with a left shift, monocytosis and the presence of toxic neutrophils. In less than 1 / 3 of the animals the presence of azotemia is present and a density lower than 1035 is detected in the urine of almost 90% of bitches which may be in normal range at the onset of the desease. Urinary protein loss is rare but the protein may be elevated in the reagent strip due to urinary contamination by uterine secretion. The increase of gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) and creatine kinase (CK) may be present, indicating disorders in the liver. Currently, additional laboratory tests are being studied for the diagnosis of pyometra and its prognosis, such as the measurement of C-reactive protein and fibrinogen for monitoring the recovery of the inflammatory process and the urine electrophoresis to characterize the origin of proteinuria in these animals . The aim of this work is to review the literature on the main laboratory tests that aid the diagnosis of Pyometra

Sanidade Uterina Pós Parto: Aspectos Imunológicos e Terapêuticos

Function of the uterus is often compromised in cattle by bacterial contamination of the uterine lumen after parturition. Pathogenic bacteria often persist, causing uterine disease, a major cause of infertility in cattle. Knowledge of the immunological aspects of the uterus involved in maintaining reproductive healthiness is fundamental to the study of uterine infections that affect the uterus postpartum. Polymorphonuclear leukocytes have an important role because they are the first line of defense against colonization of bacteria in utero (Hammon and Goff, 2006). The establishment of uterine infection depends in parts of endocrine environment, particularly progesterone, which suppresses the immune system (Lewis, 2003). In the puerperium may occur uterine disorders, such as retained placenta, puerperal metritis, clinical and subclinical endometritis and pyometra, this review was proposed a study of the immunology involved in uterine health and a better understanding of uterine disorders, using the model of Sheldon et al. al, (2006) for classification of diseases, and a study of best treatment options and discussion about its functionality, because a lot of controversy among authors about choosing a treatment and another and between treated and untreated

Piometra canina

Pyometra occurs when bacteria colonize the uterus that is under the progesterone dominance. The diagnosis can be carried out based on anamnesis, clinical signals, physical examination and laboratory findings. The prognostic of this desease is relative when the medical therapy is used as an option. The best prevention is the surgery. The present report has an objective accomplishes a literature revision it informs on the pathology in subject gathering the available information regarding the several etiologies of that desease, diagnosis, differential diagnosis, complemental exams and treatment
