The Congenital heart diseases are characterized by morphological defects in the embryonic development and the most frequent in dogs are: pulmonary and aortic valve stenosis, ventricular septal defect and persistente ductus arteriosus.  They may occur asymptomatically or even evolve to congestive heart failure. The definitive diagnosis is made through the visualization of the alterations in the echocardiogram. In the present report, a French Bulldog, three month old, asymptomatic was presented to a private Veterinary practice in Rio de Janeiro, Brazil. Cardiac auscultation evidenced a systolic heart murmur in tricuspid focus and diastolic murmur in pulmonary focus. To better evaluate the dog  chest radiography, electrocardiogram and echocardiogram were perfomed and  allowed the diagnosis of pulmonary stenosis. The clinical treatment with beta-blocker was installed and the surgical procedure was performed with the ballon valvuloplasty. The aim of this study was to report a case of pulmonary artery stenosis in a puppy, treated clinically and surgically, emphasizing the importance of the physical and complementary cardiological exams.
先天性心脏病以胚胎发育过程中的形态学缺陷为特征,在犬中最常见的有:肺动脉瓣和主动脉瓣狭窄、室间隔缺损和持续性动脉导管。它们可能无症状发生,甚至演变为充血性心力衰竭。明确的诊断是通过超声心动图改变的可视化作出的。在本报告中,一只三个月大的法国斗牛犬,无症状,被送到巴西里约热内卢的一家私人兽医诊所。心脏听诊证实三尖瓣病灶有收缩期心脏杂音,肺病灶有舒张期杂音。为了更好地评价狗的胸片,进行了心电图和超声心动图检查,并允许诊断肺动脉狭窄。应用β受体阻滞剂进行临床治疗,并采用球囊瓣膜成形术进行手术。本研究的目的是报告一例幼犬肺动脉狭窄,临床和手术治疗,强调物理和辅助心脏病检查的重要性。

The objective of this work was to quantify the economic losses caused by a botulism outbreak among beef cattle in a semi-containment regime. The animals were fed corn silage and commercial feed and had access to a pasture of Guinea grass ( Panicum maximum ). Of the 150 steers in the herd, 22 (14.6% morbidity rate) presented clinical signs compatible with botulism and died (100% lethality rate). The 22 steers were clinically evaluated and eight were necropsied. The carcasses were evaluated macroscopically, and samples of the main organs were collected for laboratory testing. Ruminal and intestinal contents, and samples of the silage and animal feed provided were also collected. Botulinum toxin type C was identified in the ruminal contents of one steer and in the corn silage. Herein, the epidemiology, clinical signs, and laboratory findings regarding botulinum intoxication are emphasized for this outbreak. Our findings show the importance of keeping the silage well preserved because this represented a means of neurotoxin transmission that generated economic damage to the producer.
这项工作的目的是量化在半控制制度下肉牛肉毒中毒爆发造成的经济损失。饲喂玉米青贮饲料和商品饲料,并在几内亚草(Panicum maximum)牧场上放牧。在150头牛中,22头(发病率14.6%)出现与肉毒杆菌中毒相符的临床症状并死亡(死亡率100%)。对22头牛进行了临床评估,其中8头进行了尸检。对尸体进行了宏观评价,并收集了主要器官样本进行实验室检测。收集瘤胃和肠道内容物、青贮饲料和动物饲料样品。在1头牛的瘤胃内容物和玉米青贮中鉴定出C型肉毒杆菌毒素。在此,流行病学,临床症状和实验室结果有关肉毒杆菌中毒是强调这次爆发。我们的研究结果表明,保存好青贮饲料的重要性,因为这是神经毒素传播的一种方式,对生产者造成了经济损失。

The aim of present study was to evaluate the prevalence of gastrointestinal parasite infection and related factors that govern prevalence in pet dogs. Of 200 fecal samples screened, a prevalence of 39% was observed, in which Toxocara canis (37%) and coccidian (29%) were predominant. Factors that could be associated with an increase in the probability of parasite detection in fecal samples included time since the last deworming, sex, and breed. Pet dogs with > 6 months since the last deworming had a 1.5 times higher probability (P 6 months since last deworming, purebred, and male dogs exhibited a comparatively higher prevalence and probability of gastrointestinal parasite infection.

Trypanosoma vivax is the most pathogenic ruminant’s hemoparasite, causing huge economic losses to the producer when prevalent in the herd. This study aims to characterize the trypanosomiasis in naturally infected cattle in order to assess the clinical findings, epidemiological risk factors and diagnosis of this disease in outbreaks occurred in the states of Pernambuco and Alagoas, northeastern Brazil.  For this purpose, historical and clinical examinations, blood collection and clinical monitoring were performed in 109 animals presenting illness for a period of one year. The main clinical findings were fever, apathy, anorexia, diarrhea, progressive weight loss, lymphadenopathy, pale mucous, incoordination, aggressiveness, abortion, decrease in milk production and high mortality. Out of 109 animals, 94% (103/109) were seropositive to Trypanosoma vivax by ELISA, 92% (100/109) were seropositive for IFAT, 15% (17/109) were positive in conventional PCR assay based on cathepsine L gene, and 9% (10/109) were showed the presence of Trypanosoma vivax trypomastigotes in stained-blood smears. In 13 samples, blood counts revealed that 69.23% (9/13) showed normocytic normochromic anemia and 53.84% (7/13) had leukocytosis, in 46.15% (6/13) neutrophilia and shift left regenerative. In 72 samples also examined whether it hematocrit, plasma protein and fibrinogen. Hematocrit presented average 22% (10% to 37%) to plasma protein had a mean value of 7.55 g/dl (5.4 g/dl to 10.0 g/dl) and plasma fibrinogen had a mean value 700mg/dl (200mg/dl to 1600mg/dl). The sequencing of DNA samples revealed 100% identicalness to T. vivax by BLAST analysis. The main factors involved in the spread of the disease were: the ingress of animals without prior tests and quarantine in the properties, application of oxytocin with sharing needles contaminated by blood at the time of lactation and the restriction of the disease in the lactation herd. The transmission of T. vivax occurred with the sharing of needles among animal’s lactation during application of oxytocin after the entry of carrier animals in the herd. Serological tests demonstrated a high rate of seropositive animals, however, conventional PCR and blood smear revealed a low rate positive animal’s because the animals were already being treated with trypanocide drugs. It is concluded that trypanosomiasis is a disease to be considered in the cattle regions studied as the cause of outbreaks. Hygienic and security actions must be taken during the administration of oxytocin in lactating cows. In fact, this practice, when carried incorrectly and without hygienic criterions and sharing needles, may play a role as the main risk factor in the transmission of trypanosomiasis in dairy herds among regions where the disease is prevalent, increasing the challenge of reinfection of animals.
间日锥虫是反刍动物中致病性最强的血液寄生虫,在群体中流行时会给生产者造成巨大的经济损失。本研究旨在描述自然感染牛的锥虫病,以评估该疾病在巴西东北部伯南布哥州和阿拉戈斯州爆发的临床发现、流行病学风险因素和诊断。为此,对109只患病动物进行了为期一年的历史和临床检查、血液采集和临床监测。主要临床表现为发热、冷漠、厌食、腹泻、进行性体重减轻、淋巴结病、粘液苍白、不协调、攻击性、流产、产奶量减少和高死亡率。在109只动物中,94%(103/109)的动物通过ELISA对间日锥虫呈血清阳性,92%(100/109)的动物对IFAT呈血清阳性。在13个样本中,血液计数显示69.23%(9/13)表现为正常细胞性常铬性贫血,53.84%(7/13)有白细胞增多症,46.15%(6/13)有中性粒细胞增多症并向左再生。在72个样本中还检查了是否为红细胞压积、血浆蛋白和纤维蛋白原。血细胞比容平均22%(10%至37%),血浆蛋白平均值为7.55g/dl(5.4g/dl至10.0g/dl),血浆纤维蛋白原平均值为700mg/dl(200mg/dl至1600mg/dl)。通过BLAST分析,DNA样品的测序显示与间日疟原虫100%相同。该疾病传播的主要因素是:未经事先测试和检疫的动物进入动物体内,在哺乳时使用被血液污染的共用针头应用催产素,以及该疾病在哺乳群中的限制。间日疟原虫的传播发生在携带动物进入牛群后应用催产素期间,动物泌乳期间共用针头。血清学测试显示,动物血清阳性率很高,然而,常规PCR和血液涂片显示,动物的血清阳性率较低,因为这些动物已经在接受锥虫类药物治疗。得出的结论是,锥虫病是一种在所研究的牛区被视为疫情爆发原因的疾病。哺乳期奶牛使用催产素期间必须采取卫生和安全措施。事实上,如果这种做法不正确,没有卫生标准和共用针头,可能会成为锥虫病在奶牛群中传播的主要风险因素,从而增加动物再次感染的挑战。

The autonomic nervous system (ANS) plays a role in the regulation of the cardiovascular system through sympathetic and parasympathetic modulations, which act in an associated way in the regulation of homeostasis. This regulation exercised by the ANS is determined by numerous factors including breathing, stress, temperature, blood pressure and physical activity. Cardiac nerve regulation is influenced by obesity, but the autonomic response present in this disorder has not yet been elucidated. It is known that a 10% increase in body fat is able to lead to a decrease in parasympathetic action and an increase in heart rate. Heart Rate Variability (HRV) allows the evaluation of autonomic heart modulation through the ventricular depolarization intervals to the electrocardiogram (ECG), and provides information on the relationship and contribution of the ANS to the neural influence of heart rate control. The objective of the present study was to evaluate the HRV by means of an electrocardiographic examination in obese dogs with Body Condition Score (BCS) 8/9 and 9/9, comparing with HRV of the same animals, after therapy with therapeutic ration in the period of 6 months, as well as the comparison with control group with lean animals. With the results obtained in the present study, it can be inferred that probably the imbalance in the autonomic activity due to obesity in dogs is not the same as in humans and that a greater understanding of this regulation in these animals is necessary, especially considering their vagotonia. The diet program based on low-calorie ration reached approximately 10% and 20% of weight reduction after two and six months, respectively. Obesity raises HRV by increasing parasympathetic activity in the autonomic regulation of the heart in dogs.
自主神经系统(ANS)通过交感和副交感神经调节在心血管系统的调节中发挥作用,而交感和副交感神经调节在调节体内平衡中起着相关的作用。ANS的这种调节是由许多因素决定的,包括呼吸、压力、体温、血压和身体活动。心脏神经调节受到肥胖的影响,但在这种疾病中存在的自主神经反应尚未阐明。众所周知,体脂增加10%会导致副交感神经活动减少和心率增加。心率变异性(HRV)允许通过心室去极化间隔到心电图(ECG)来评估自主心脏调节,并提供关于ANS与心率控制的神经影响的关系和贡献的信息。本研究的目的是通过对体况评分(Body Condition Score, BCS)为8/9和9/9的肥胖犬进行心电图检查,评估其HRV,并与相同动物的HRV进行比较,在6个月的治疗期间给予定量治疗,并与瘦动物对照组进行比较。根据本研究的结果,我们可以推断,狗肥胖引起的自主神经活动失衡可能与人类不同,有必要对这些动物的这种调节进行更深入的了解,特别是考虑到它们的迷走神经。以低热量配给为基础的饮食计划在两个月和六个月后分别达到了大约10%和20%的体重减轻。肥胖通过增加狗心脏自主调节中的副交感神经活动来提高HRV。
