Tristeza Parasitária em bovinos na região de Botucatu – SP: estudo retrospectivo de 1986 – 2007

A retrospective study of Cattle Tick Fever was made with animals up to one year old, which occurred from 1986-2007 in Botucatu-SP in the influence area of the Veterinary Hospital of the School of Veterinary Medicine and Animal Science - UNESP. There were 232 cases and 57 deaths. The main etiological agent causing the disease on this region is Anaplasma marginale identified as a single agent in 31.5% of the cases. Most of the cases occurred on autumn in mixed-blood animals two to six months old. Predominant clinical signs included apathy, hyporexia or anorexia, dehydration, weight loss and pale mucosa. The high incidence and mortality observed justify prophylactic actions to have the balance between host, agent, vector, and environment, thus avoiding the clinical form of disease and death of livestock herds in the region.

O leucograma como indicador de estresse no desmame e no transporte rodoviário de bovinos da raça Nelore

Stress can cause economic losses due to lower weight gain and increased susceptibility of animal diseases. Among the events that cause stress in calves, stand out weaning and road transport, which can result in increased serum concentrations of adrenaline and / or cortisol. This study evaluated the influence of weaning and road transport on the leukogram of Nelore calves. With this purpose, 30 calves with seven to eight months of age, divided into three groups, the first being composed of lactating animals (GL), the second by weaning animals (GD) and the third by weaning animals subjected to road transport for four hours (GDT). The first day of weaning, but not in subsequent days, there were changes in GD and GDT leukogram compatible with the action of adrenaline, as significant increases counts of WBC and neutrophils (p < 0.05), without changing in the neutrophil lymphocytes ratio (NL). In the GDT, immediately after transport, but not in subsequent days, leukogram changes were (p < 0.05) compatible with the action of cortisol, as higher N: L ratio and decreased eosinophil count. It was concluded that, under the conditions of this experiment, there are changes in leukocytes on weaning and road transport related to the action of adrenaline and road transport, respectively, and that the WBC can be used as an indicator of stress in this species.

Facial paralysis associated to hypothyroidism in a dog

The hypothyroidism is the most commonly endocrinopathy in dogs, that occurs preferentially in middle-aged pure breed. The clinical signs associated with hypothyroidism are variable, many times non-specific, including metabolical, dermatological or cardiovascular. The main laboratorial findings are non-regenerative anemia and hypercholesterolemia. Hyponatremia, increase on alanine transferase and alkaline phosphatase activity also can be observed in a lower frequency. There are some reports of peripheral neuropathies caused by hypothyroidism, but the pathophysiology of this process is still unknown. There are specific diagnostic tests that can be used to help diagnose hypothyroidism, and those should be aligned together with the animal's clinical symptoms. The thyroxine stimulating hormone, and free and total thyroxine concentrations are the most used tests. A Pit Bull dog, female, over weighted, was treated presenting left facial paralysis. Thyroid function tests confirmed hypothyroidism. The animal was treated with hormonal replacement and there was improvement in clinical signs in 40 days, confirming that hypothyroidism was facial paralysis' cause.

Prostatic abscess in dogs: report of 15 cases

Fifteen cases of dogs with prostatic abscesses are reported. The animals were underwent to physical examination prioritizing the digital rectal exam with transabdominal palpation of the prostate gland followed by blood cell count, measurement of serum urea, creatinine, alanine aminotransferase and alkaline phosphatase levels, abdominal's radiographic and ultrasound exams, and culture of the prostate. The animals were underwent to different treatments being related to the animal's general state, location, size and quantity of prostatic abscesses. This description reiterates the importance of prostatic disease in canine medicine once the detailed physical examination associated with specific complementary tests, particularly x-ray and ultrasound, are valuable for the detection of dog's prostatic diseases. Surgical procedures used here are effective to the treatment of prostatic abscesses with low mortality rate.

Detecção de anticorpos anti-Toxoplasma gondii em animais de uma comunidade rural do Mato Grosso do Sul, Brasil

The rate of anti-Toxoplasma gondii antibodies was evaluated in equines, cats, dogs, poultry, pigs, cattle and sheep of farms in Eldorado, southern Mato Grosso do Sul. Blood samples were collected and sera were examined by the modified agglutination test (MAT), considering positives samples reactants with titers >= 25. Rates of reactor animals in the antibody detection test were: 22.89% (46/201) in poultry, 5.15% (20/388) in cattle, 47.61% (20/42) in dogs, 60.87% (14/23) in equines, 57.14% (8/14) in cats, 14.7% (5/34) in pigs. None of the sheep (0/14) were positive. High antibody rates were found in several species, a fact that raise concerns due to the possibility of risk to humans, once these animal species either share the same source of infection with humans or are food sources for them.

Correlação dos achados clínicos e hematológicos com diagnóstico definitivo de erliquiose canina por meio de PCR

The Ehrlichiosis is a worldwide diseases of great importance in a veterinary medicine is an important infectious diseases whose prevalence has increased significant in the last year in the Brazilian states. Due to the fact that this study was designed to correlate the findings hematological clinical signs and PCR, being the most sensitive. This study evaluated twenty dogs seen at veterinary hospital UNESP - Botucatu campus during the 03 from august to September 28 2009. Animal cited 65% were positive in the PCR test. Among the most prominent clinical findings 76.92% (10/13) with anorexia, 53.84% (7/13) with hepatoesplenomegaly, 46.15% (6/13) with apathy and 38.46% (5/13) epistaxis. The thirteen animals positive PCR 92.30% (12/13) showed thrombocytopenia (<150.000 platelets) e 61.53 (8/13) anemic (<5.50 x10). Thus, we conclude that the PCR was a good method for detection differential canine ehrlichiosis may be adopted together with the clinical and hematological findings for the accurate diagnosis of the disease.

Influência de um nutracêutico no sêmen, testosterona, cortisol, eritrograma e peso corpóreo em touros jovens Bos taurus indicus

The purpose of this study was to investigate the nutraceutic (Promater (R)) influence on semen, body weight, eritrogram and hormones testosterone and cortisol in Nelore young bulls. Twenty Nelore bulls were utilized, aging between 30 and 36 months, divided in group 1 (G1)= 10 (control) and group 2 (G2)= 10 (nutraceutic group - Promater (R): 20 mL/animal/day, during 70 days). Corporal weight, blood samples to eritrogram, testosterone and cortisol were obtained in days zero (D0), 35 (D35) and 70 (D70) in two groups. There was difference (P<0.01) among days collected (0, 35 and 70) with means of 424.30 kg, 480.70 kg and 502.60 kg, respectively, but there was not difference between groups. There was not difference among groups to semen, eritrogram, cortisol (G1 = 3,19 mu g/dL; G2 = 2,91 mu g/dL) and testosterone (G1 = 274,48 ng/dL; G2 = 509,65 ng/dL). The results exposed allow concluding that were not observed significative effect of the nutraceutic upon evaluated parameters: body weight, semen, hormonal profile and eritrogram.

Produção, propriedades e aplicações de oligossacarídeos

Oligosaccharides participate in the formation of dietary fiber and are mainly used as prebiotic agents. This review presents ways of obtaining these sugars, which can be produced by synthesis (chemical or enzymatic), or through depolymerization of polysaccharides (physical, chemical or enzymatic). Oligosaccharides have also been used commercially as an ingredient in cosmetics, pharmaceuticals, agricultural products and especially in the food industry because of their physical properties. The potential applications of oligosaccharides in several areas such as food, animal feed, pharmaceuticals and cosmetics have contributed to the increase in scientific research on these carbohydrates. The use of oligosaccharides as immuno-modulatory agents and biological response modifiers has been recently described, and their effects as anti-inflammatory and in reducing cholesterol. An overview of the various nutraceutical and biological functions of these carbohydrates in order to benefit human health is also reported.

Síndrome vestibular em tamanduá-bandeira (Myrmecophaga tridactyla)

The vestibular syndrome is a well-defined disease in domestic animals but little known in wild ones. Here this affection of central origin is described in a caquetic adult female giant anteater (Myrmecophaga tridactyla), which presented circling behavior, extensor hypermetry in thoracic limbs, head tilt and spontaneous horizontal and positional vertical nystagmus. The animal received tube feeding twice daily and dexamethasone was given subcutaneous once daily at the dosis of 6mg/kg, with a progressive improvement of health after the second day of treatment. Dose was reduced to a half from fourth to sixth day, and to a quarter on seventh day, when the animal died. on the fifth day, however, circle deambulation had ceased and hypermetry, head tilt and nystagmus were reduced. Treating vestibular syndrome is a challenge in wild animal practice. Treatment is affected by hyporexia and anorexia, making difficult the animals' health improvement, which generally present muscle atrophy.

Níveis de proteína bruta e de energia metabolizável para frangas de postura semipesadas de 1 a 18 semanas de idade

The aim of this experiment was to evaluate the performance of commercial layers between 1 and 18 weeks of age submitted to different crude protein (CP) and metabolizable energy (ME) levels. The trial was carried out at the poultry sector of the Department of Animal Science, of the Centro de Ciencias Agrarias, Universidade Federal of Paraiba, Areia-PB, Brazil. Four hundred and thirty-two Lohmann Brown chicks were used at 3 days of age according to a completely randomized design in a 3 x 3 factorial scheme, with three CP levels and three ME levels. In the first phase (1-6 wk), the birds were fed with diets containing three levels of CP: 21, 22 or 23% CP and three levels of ME: 2,900, 3,000 and 3,100 kcal/kg diet. In the second phase (7-12 wk) and in the third phases (13-18 wk), CP levels of feeding were 18, 19 or 20%, and 16, 17 or 18%, respectively, and three ME levels being 2,700, 2,800 or 2,900 kcal ME/kg diet in these two phases. It was not found interaction between CP and ME levels. Based on the results obtained one recommends for the phases from 1 to 6, 7 to 12 and 13 to 18 weeks of age the levels of 21 % of CP and 2900 kcal of ME/kg diets, 20% of CP and 2700 kcal of ME/kg diets and 16% of CP and 2700 kcal of ME/kg diets respectively.
