Comparative analysis of lung function of rats using a new intubation technique and tracheostomy Texto completo
2017
Daniel Silveira Serra | Kaio Bruno Pereira de Brito | Francisco Sales Ávila Cavalcante
Several studies use intubation or tracheostomy for data collection in lung function of rats. Due to the difficulty of performing intubation, tracheostomy is most commonly used. Knowing this difficulty, this paper demonstrates a new way to perform the intubation technique and compares pulmonary function variables obtained using intubation or tracheostomy. For the analysis of our new technique of intubation, 30 rats were used, and the comparative analysis of lung function data obtained through the use of our technique of intubation and tracheostomy, 16 rats were used, divided into two groups. The T group underwent tracheostomy. The IT group underwent initial intubation and, awaiting recovery, a week later was again subjected to intubation group, which was then called IT-1W. Our intubation technique is performed with the aid of a wedge, inclined bed and percutaneous transillumination. No animals died during the intubation procedure, and about 77% of the animals were intubated at the first attempt. We did not obtain statistically significant differences in the pulmonary function variables between the groups. Our intubation technique is easily learned and reproduced. The implications of such a technique can be generalized to all laboratories dealing with intubation of rats.

The interest in embryology, the science of the development of a zygote into a completely developed foetus, has increased greatly in recent years due to a number of studies involving embryonic and induced pluripotent stem cells. In addition, the development of techniques such as cloning has aided to understand the critical events that occur during embryonic development. In this study, we describe the morphology of two sheep embryos and one foetus using macroscopic and microscopic techniques. We investigated sheep without defined breed on days 24, 32, and 50 of gestation (estimated by crown-rump length [CR]). Macroscopically, we observed the development of E1 (24 days), with visible optic vesicle, but without retinal pigmentation and the forelimbs bud in development. In the E2 (32 days), we noticed the presence of optic retinal pigmentation and forelimbs more developed in comparison with E1. As expected, F1 revealed an eyeball already covered and the forelimbs developed. Meanwhile, microscopic analysis revealed somite, ventricle, atrium, and oral cavity in development in E1. However, in F1 we were able to identify more complex structures, such as ossification in the spine, ventricle, atrium, intraventricular septum, pericardial sac, and oral cavity with tongue. This work brings more precise and detailed data on the morphological characteristics of the major organ systems (nervous, circulatory, respiratory, digestive, and urinary) at each embryonic and foetal stage analysed.

Greenwell, Phillip J. | Montrose, V Tamara
Gray parrots (Psittacus erithacus) are popular companion birds, particularly noted for their ability to mimic human speech, their intelligence, and longevity. They are also prone to developing abnormal behaviors such as feather damaging behavior. This review explores the current available knowledge on gray parrots kept as companion birds with respect to behavioral problems and their management. The potential causes for the development of abnormal behaviors in this species are explored. Recommendations are made for future research, and advice is provided on the synthesis and application of available research to owners, breeders, and clinicians of gray parrots so that their well-being is maximized in captivity.

One of the Acehnese traditional food preserved by the addition of salt, acid and dried was sie balu. The preservation method may lead to changes in the structure and nutritional content. Sie balu with the addition of vinegar, garlic and ginger can reduce the value of water activity (aW), pH and bacterial counts. This condition affects the physical properties and sensory of sie balu. Irradiation can control pathogenic microorganisms in meat without affecting the physical condition. Low-dose irradiation is able to maintain the desired sensory attributes nutritious food products. This study aims to determine the characteristics of the sensory and physic sie baluthat irradiated with increasing doses and the shelf life of 3-6 weeks. Sie balu was made of 10 kg fresh beef, dried in the sun to dry, vacuum and irradiated at doses of 5, 7 and 9 kGy. Sensory test conducted by taste sie balu by trained panelists and fill out the hedonicform. The physical properties based on pH and aW. The microbe total calculated used Total Plate Count.The results showed that the irradiation dose significantly (P 0.05) affected on microbe total, aroma, color, texture and taste of sie balu. Storage time does not affect the sensory properties. Irradiation dose and storage time significantly (P 0.05) on pH and aWsiebalu. The study concluded that irradiation can improve the physical properties, sensory and microorganisme reductionof sie balu.

Toxoplasmosis is one of the most common zoonoses worldwide. It was initially described in rodents and rabbits. There are few data on the morbidity and mortality of this disease among Brazilian marsupial fauna, such as opossums. These animals are of great importance regarding the epidemiology of this disease, given that they are prey for felids and other carnivores. With the aim of ascertaining the serological response to Toxoplasma gondii among marsupials (Didelphis spp.), 38 animals that had been caught in 14 districts of the urban area of the municipality of Bauru, state of São Paulo, were evaluated. The modified agglutination test (MAT) showed that 26.3% (10/38) of the samples analyzed were seropositive. It can be suggested that the opossums’ behavior and persistent proximity to human housing results in contact with cats and T. gondii infection, based on the frequency found in this study. This was the first study on the seroprevalence of T. gondii in opossums caught in the urban area of the municipality of Bauru, SP, and it highlights the need for environmental and health authorities of the municipality to monitor this zoonosis.

The multidrug resistant and the emergence of methicillin-resistant staphylococci isolated from animals, food, and humans are public health concern. These microorganisms produce different toxins related to food poisoning in humans. This study aimed to characterize Staphylococcus spp. isolated from two organic milk farms in Brazil. A total of 259 milk samples were collected, from which 58 (22.4%) Staphylococcus spp. were isolated. The highest sensibility to ceftiofur and sulfamethoxazole/trimethoprim was observed in 96.6% of Staphylococcus spp., and whereas 89% were resistant to penicillin G. The mecA gene was detected in 13.8% of the isolates. SEA and SEC were the most common enterotoxins detected. PFGE revealed genetic heterogeneity from S. intermedius and S. warneri analyzed, while S. aureus presented similar profiles among isolates from the two studied herds. To the best of our knowledge, the current study describes for the first time presence of enterotoxins, mecA gene, and genetic diversity of staphylococci isolated from organic dairy farms in Brazil.

Fabio Alves Teixeira | Marcio Antonio Brunetto
Diabetes mellitus is a chronic disorder that results in hyperglycemia by absolute or relative insulin deficiency, sometimes leading to fatal complications. The successful treatment of diabetic dogs depends on nutritional management and insulin applications. Studies evaluating the nutrition of diabetic dogs focused on fiber as the main factor in glycemic control; however, new research describes the role of starch as key in postprandial glycemic fluctuation, also attributing a central role for body condition scores and feed management in the adequate glycemic control of diabetic dogs. The aim of this paper is to review nutritional aspects to better control diabetes in dogs.

Although pain is considered the 4th vital sign and one of the most frequently observed clinical signs in domestic animals’ clinical practice, its treatment is still inadequate despite significant improvement in the last few years. Acute post-operative pain has aroused great interest due to its potential risk of developing into chronic pain, and if not treated properly, it might worsen the recovery and the patient’s quality of life. Cats are one of the least studied species of domestic animals regarding pain recognition and control. Some of the difficulties lie in pain assessment and perception. The consensus published in February 2016 about behavioral signs of pain in cats considered some signs to be reliable and sensitive for the assessment of pain in this species in many different clinical conditions, however it still states that more studies will be necessary in order to evaluate its clinical validity and applicability, especially considering the various pain intensities. As an attempt to quantify pain intensity in cats, several types of traditional subjective scales and others that facilitate pain assessment by combining the observation of spontaneous behavioral signals of pain and qualitative response to palpation of surgical wound are used as tools. It is necessary to use specific scales for each type of pain and for each specific animal species so to minimize the subjectivity and the partiality of the observers, reducing bias and improving efficacy, thus leading to a better patient care.
