Since 2008, when the US Environmental Protection Agency (EPA) registered copper and its alloys as an antimicrobial agent for contact surfaces, research has demonstrated their antimicrobial activity. The aim of this study was to evaluate the efficacy of antimicrobial copper against bacteria and fungi isolated from commercial poultry hatcheries in order to develop a microbiological control alternative in these environments. Samples were collected from the surfaces of hatcher baskets from two hatcheries. Mesophilic microorganisms and fungi/ yeasts were isolated and standardized in concentration of 105 cells/ mL. Four copper plates and four stainless steel plates were completely immersed for one minute in bacteria and fungi/yeasts solutions and left to dry for a day at room temperature. Subsequently, samples were collected from the metal plates with the aid of sterile swab and delimiter. These samples were planted onto Plate Count Agar (for mesophilic culture) and Sabouraud Dextrose Agar (for fungi and yeast culture) and incubated at 36°C for 48 hours and at 25°C for 5-7 days, respectively. After incubation, the colonies recovered from the plates were counted according to IN 62 of the Brazilian Ministry of Agriculture. Almost all contamination was eliminated from the surface of copper plates in a single day, while the stainless steel plates proved to be innocuous to the screened microorganisms. Copper, as a contact surface, proved to have important antimicrobial action on bacteria, fungi and yeasts common to hatcheries. © 2016, Fundacao APINCO de Ciencia e Tecnologia Avicolas.

The objective of this study was to verify the stage of sexual maturity, occurrence of the testicular format and the relationship among reproductive characteristics. Data were used from 5903 Nellore bulls averaging 21 months submitted to the soundness evaluation from 1999 to 2003. At the time of the evaluation, the following characteristics were recorded: scrotal circumference at soundness evaluation (31.99 ± 2.23 cm), left testicular length (11.21 ± 0.98 cm) and right testicular length (11.26 ± 0.97 cm), left testicular width (5.92 ± 0.44 cm) and right testicular width (5.97 ± 0.46 cm), testicular format (1.72 ± 0.46), testicular volume (632.21 ± 132.72 cm 3), individual motility (69.56 ± 12.31%), vigor (2.87 ± 0.61), as well as total defects (22.19 ± 11.13%) and major defects (15.86 ± 10.45%) of the spermatozoa. The frequencies of the testicular formats were long (30.80%), long-moderate (66.19%), long-oval (2.49%), oval-spherical (0.02%) and spherical (0.04%). Correlations between the scrotal circumference and the reproductive traits were positive. Scrotal circumference is a good trait for selection of young Nellore bulls. More than 70% of the animals studied are sexually mature at 21 months old. © 2010 Sociedade Brasileira de Zootecnia.

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.

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.

Many families use wagon pulled by traction horses as their means of work or supplemental income. In Pelotas, there has been a Veterinary Clinic since 2006, which provides free weekly clinical care to these horses, due to concern about their health. The objectives of this study were to evaluate and record the biometric patterns of traction horses in Pelotas. We evaluated 219 horses, 129 females and 90 males. We measured chest width (ChW), leg perimeter (LP), thoracic perimeter (TP), croup width (CrW), height (H) and weight (W) of the animal. Through these values, we calculated the compactness index 1 (CCI1=(W/WH)/100), compactness index 2 (CCI2 = (W/[WH-1]/100) and conformation index (CFI=TP2/WH). The animals of both sexes showed the following averages: H -1.38 ± 0.07 m; LP -0.19 ± 0.02 cm; TP -1.56 ± 0.10 m; ChW -0.26 ± 0.05 cm; CrW -0.22 ± 0.05 cm; weight -308 ± 60 kg. Regarding the ICC1, ICC2 and ICF indices, the averages for both sexes were, respectively: 2.30; 8.39; 1.82. Accordingly, the indices obtained showed that most of the evaluated horses were inadequate to pull heavy loads and had greater ability to pull light loads or to be used as riding horses.

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.

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.

The syndrome of gastric dilatation volvulus (GDV) is a severe condition of acute character, which gives a high rate of death in small animals. The etiology is not fully established, however, several treatment options have been described. The DVG causes severe reduction in tissue perfusion, affecting many organs, including the respiratory and cardiovascular systems. This study aims to conduct a comprehensive literature review of the pathogenesis of this syndrome as well as its treatment.

The aim of this study was to characterize the orthopedic diseases of the hind limbs in dogs examined at the Veterinary Hospital of the School of Veterinary Medicine and Animal Science, Univ Estadual Paulista (UNESP) - Botucatu (São Paulo - Brasil), during a period of 7-years. A total of 889 dogs were evaluated: 31.9% had fractures of the long bones, 15.1% hip dysplasia, 13% medial patellar luxation, 11.7% cranial cruciate rupture, 11.5% multiple pelvic fractures, and 7.9% hip dislocation. The low-prevalence disorders (4.4%, n=39) were tibiotarsal and tarsometatarsal luxations, avascular necrosis of the femoral head, osteomyelitis and bone tumors, among others. Fractures of the tibia/fibula (14.5%) were more common than femoral fractures (14.2%), and males (54.2%) were more affected than females (45.8%). Considering the dogs with hip dysplasia, 67.9% were aged between 2 and 12 years, and the most common breed was the German shepherd (21.6%) followed by Rottweiler (17.2%) and Labrador (11.2%), while the mixed-breed dogs were 15.7% of total. Of the dogs with patellar luxation, 89.6% had medial luxation, and 36.2% were Poodle, 16.4% were mixed-breed and 12.9% were Pinscher. Cranial cruciate rupture was observed especially in Pit Bull (14.4%), Boxer (11.5%), Poodle (10.6%) and Rottweiler (10.6%) dogs, and mixed-breed dogs constituted 29.8% of the total. According to the age, 62.5% of them had less than 7 years. The most important cause for pelvic fractures was motor vehicle accidents (89.2%), being 52% of the dogs less than 3 years old and 45.1% of them were males. In 86.3% of the cases there were multiple fractures of the pelvis. Considering the dogs with hip dislocation, 57.1% of the cases were associated with motor vehicle accidents. The age ranged from 2 to 18 years, with high prevalence in mixed-breed dogs (44.3%), followed by Poodles (32.9%). In conclusion, the most often orthopedic diseases in decreasing order of occurrence were fractures of the long bones, automobile-induced; hip dysplasia, medial patellar luxation, cranial cruciate rupture, multiple pelvic fractures, and traumatic hip dislocation.
