On 26 October 2012, veterinary medicine clinicians and researchers, members of Brasileish - Study Group about Animal Leishmaniasis - met at the Regional Council of Veterinary Medicine of Minas Gerais, in the city Belo Horizonte, in order to discuss many aspects of the situation of canine visceral leishmaniasis (CVL) in Brazil. In the face of recent national and international scientific evidence, we, the members of Brasileish, have elaborated some recommendations for the management and control of CVL in Brazil. © 2013 Ribeiro et al.; licensee BioMed Central Ltd.

Objective. To analyze the presence of yeast in the external ear canal of 116 dogs with and without a diagnosis of otitis from veterinary clinic in the Chapecó city, Santa Catarina, Brazil, and to examine the secretion of the proteinase in isolates. Materials and methods. Were collected cerumen of conduct hearing of dogs of 16 different races 71% with pendular ear type, 5% of semi-pendular and 24% of the erect type. All dogs were previously evaluated by otoscopy and grouped in dogs with and without otitis. Results. Yeasts were isolated in 44 samples (approximately 36%), where Malassezia pachydermatis was identified in 95% of samples where were observed growth of yeasts. On 20 samples the proteinase enzyme showed strong activity in 31% isolates, were 21% of the dogs with otitis tested showed high proteolytic activity. Conclusions. We observed a variation of strains of M. pachydermatis-producing enzymes. The variation in production of these enzymes is probably more associated with different response to the action of the immune system of the animal in the tissue injury. Source

This study presents qualitative and quantitative data on fish borne diseases in Brazil covering from 1983 to 2010. The article covers infectious diseases caused by bacteria, virus, and parasites, as well as intoxications caused by bacteria, biotoxins and chemical contaminants. Among the food borne diseases, the resulting information shows a serious lack of epidemiological data on fish borne diseases in Brazil. Limited available data indicates that, in contrast with other food borne diseases (transmitted by meat, poultry, dairy and other food); fish borne diseases would have a different etiological picture: intoxications would be more common than infectious diseases caused by pathogenic bacteria. Intoxications caused by biotoxins (DSP and tetradotoxin) and botulism followed by parasitic ictiozoonoses (diphyllobothriasis and fagicolosis) would be those fish borne diseases that deserve a higher prevention and control effort. © The Costume Society 2014.

Plants of genus Crotalaria have been reported as poisonous for many species of domestic animals. The aim of this work is to report, for the first time in Brazil, an outbreak of C. incana poisoning. The outbreak took place in Nova América da Colina County, Northern region of Paraná state, Brazil, causing death of 30 Nelore heifers in a herd of 223 animals, between 3 and 5 years old. The animals were grazing on pasture fully infested with C. incana. The main clinical signs were characteristic of hepatic encephalopathy and consisted of blindness, depression, aggressiveness, recumbency and death in 48 hours. Gama-glutamyltransferase, and alkaline phosphatase activities were increased. The main necropsy findings were liver congestion and evident lobular pattern, increased gall bladder volume and mesentery oedema near gall bladder. Histological exams showed hepatic hemorrhagic centrolobular necrosis, megalocitosis and spongiform degeneration in thalamus. Morbidity and lethality rates were, respectively, 13,45% and 100%. Epidemiological, clinical and pathological findings suggest that C. incana poisoning was the cause of illness. Source

Stomoxys calcitrans is known for its painful sting that causes stress in animals and also by transmitting several diseases, and attack man. Due to the outbreaks in sugarcane fields in Brazil, where the vinasse is used in fertigation of the sugarcane fields, this study was conducted, aiming to verify if the vinasse would improve posture and development of the immature stages of this insect. For this, eggs were deposited into diet of larval growth of Bailey (control), and also in diets with replacement of 5, 10, 20 and 30% of this water volume per vinasse. Part of the results was submitted to analysis of variance and means were compared by Tuket test, and the other, was assessed by Chi-square. The eggs viability was of 66%, 64%, 69%, 80% e 20%, the larvae was of 96.4%, 96.,9%, 95.1%, 99.3% e 97.2% and the pupae was of 90.2%, 94.7%, 93.5%, 91.5% and 86.1%, respectively to the control, 5, 10, 20, e 30%. The weight of the third stage larvae was 16.4; 16.9; 19.7; 15.8 and 18mg, and pupae was of 12.9; 13.9; 17.4; 14.5 e 21.9mg. The larval period was of 10.38, 11.81, 10.00, 10.86, 9.5 days, and the pupal was of 6.57, 6.19, 7.05, 7.00 and 6.00 days, respectively. The viability of the immature stages was higher in diet with replacement of vinasse. Some of vinasse concentrations used in diets affected the biology of immature stages of S. calcitrans. Source
