The center of rotation of angulation (CORA)-based leveling osteotomy (CBLO) technique was developed for cranial cruciate ligament (CrCL) rupture treatment, aiming to modify the mechanical-anatomical angle (AMA), which is described as a predictive risk factor for the disease and is recommended to be taken into consideration when one is choosing a surgical procedure for tibial plateau slope alteration. Identifying a tibial distal anatomical axis (DAA) is essential in CBLO surgical planning and measuring AMA amplitude. The aim of this study was: to evaluate two methods of cranial rotation of the proximal fragment using four different tibial distal anatomical axes for digital planning on the CBLO technique, comparing its effectiveness in achieving the desired tibial plateau angle (TPAd) and closing the AMA angle. Tibial measurements were made with the vPOP pro software using 30 mediolateral radiographs of canine stifles. The DAA described by four authors was used based on the amount of Rotation completed (Rc) for each. The rotation methods evaluated were: 1) commercial CBLO table (RT) and 2) overlapping the tip of the intercondylar eminence with the corresponding DAA line (RE). The TPAd to be obtained was fixed at 10°, and the final AMA to be achieved at 0°. The mean values and standard deviations of the final TPA and final AMA with the rotation method were TPA(RT)f(%TPAd), TPA(RE)f(%TPAd), AMA(RT)f(%AMAzero), AMA(RE)f(%AMAzero). The results of each author were Hulse 10.0 ± 0.3(46.6%), 9.9 ± 0.1(60%), 0.3 ± 0.3(33.3%), 0.3 ± 0.3(13.3%), Osmond 10.1 ± 0.2(75%), 10,1 ± 0.2(83.3%), 0.4 ± 0.4(33.3%), 0.4 ± 0.3(8,3%), Miles 10.0 ± 0.1(66.6%), 10.0 ± 0.1(75%), 0.2 ± 0.1(16.6%), 0.2 ± 0.1(8.3%), Tudury 9.6 ± 0.6(31.2%), 9.5 ± 0.2(31.2%), 1.0 ± 0.7(18.7%), 1.0 ± 0.6(12.5%), respectively. The initially described RT obtained a higher percentage of AMA at zero degrees. Therefore, the RE method is discarded for use as an alternative to CBLO planning.

Zoonotic Surveillance Divisions (ZSDs) rescue and euthanize bats in contact with humans. The euthanasia procedure should be conducted safely for the animal and caretaker and minimal stress for the animal is important. The objectives of this study were: i. evaluate the methods of euthanasia used by ZSDs in the State of São Paulo; ii. compare the methods with national and international guidelines for animal euthanasia practices; iii. assess the methodologies considering taxonomy and eating habits of the main bat species, and iv. propose standardization of euthanasia procedures. Sixty-five ZSDs locations received an online questionnaire or were contacted by telephone and 33 ZSDs (50.8%) responded and are distributed in 11 mesoregions in the state to remain anonymous. The euthanasia methods were divided into chemical (injectable or inhalation), physical, or mixed methods. Bat specimens (n = 550) were identified and classified to evaluate the main genera found in the state. The location of the ZSD, species, eating habits, and the method of euthanasia used were analyzed. The specimens by bat families were Molossidae (n = 340), Phyllostomidae (n = 171), and Vespertilionidae (n = 39). Chemical methods were used in 25 ZSDs (75.75%), physical in 5 (15.15%), and mixed in 3 (9.09%). There is no uniformity or standardization in bat euthanasia methods used by ZSDs, although most are based on acceptable chemical methods. It was proposed an algorithm to assist the veterinarian in choosing the method of euthanasia for bats that will allow standardizing euthanasia procedures for this species, considering physiological differences, and respecting technical, bioethical, and animal welfare guidelines.

This review summarized the significant results from Brazilian studies published in peer-reviewed scientific papers about the effect of bovine subclinical mastitis (SM) on economic performance and milk production. Different approaches were considered for (i) disease detection (indirect measurement of somatic cell count (SCC) and directly using microbiological culture) and (ii) milk sampling strategy (mammary quarters, composite cow samples, and bulk milk tank). Globally, bovine mastitis is the most common disease of dairy herds, and the subclinical presentation is the most frequent. Dairy farmers usually underestimate the economic losses associated with SM because no visual changes in milk and quarters, udder, and systemic symptoms are observed. SM reduces milk yield and quality, reducing dairy herds’ profitability. The estimation of losses depends on the causative pathogen, the lactation stage, and the parity of affected cows. Thus, estimating the economic caused by SM in milk production and economic performance in dairy herds can be used to decide which mastitis control strategies to adopt. Mastitis control involves adopting specific measures associated with the characteristics of each herd, the period of the highest frequency of cases, the transmission form, and the profile of the pathogens involved in cases of intramammary infection. Thus, using individual SCC, the microbiological identification of pathogens causing SM, adopting efficient drying-off protocols, and other management practices are essential for mastitis control, improved milk quality, and greater profitability of dairy herds.

Australian Cattle Dogs (ACD) are medium-sized animals widely used in fieldwork for managing cattle and sheep. There needs to be more information about the conditions these dogs can develop despite being well-characterized animals since the beginning of the 20th century. Hip dysplasia (HD) is a developmental abnormality between the femoral head and the acetabular fossa, which can be debilitating. However, the available literature has no studies on the prevalence of this condition in dogs of this breed. This study aimed to evaluate radiographs of ACD qualitatively and quantitatively. For this purpose, 49 dogs considered healthy without clinical signs of HD were radiographically assessed, and the animals were classified as dysplastic (D) and non-dysplastic (ND). A frequency of 46.9% of dysplastic dogs was observed, with males being more affected. The cortical index (CI) and angle of inclination (AI) could not differentiate D from ND animals; only the Norberg angle (NA) was effective in this differentiation. No correlation was observed between AI, CI, and AN.

Rescue and recovery dogs intercalate the activity intensity developed, which also triggers significant metabolic changes in cardiac physiology. Thus, we evaluated the changes that search simulation causes in glucose, lactate, and cardiac troponin I level (cTnI) and the electrocardiographic and heart rate during the activity and recovery phase to predict the physiological adaptation to the exercise. Five healthy adult dogs from the Rescue and Recovery Service of Military Firefighters Corps were submitted to 60 minutes search operation simulation in the woods. They covered a forest area of approximately 50,000 m2. The dogs were loose and accompanied by their driver, and they could perform any physical activity. Were evaluated serum biochemical analysis of glucose, lactate, cardiac troponin I, electrocardiographic, and heart rate (rest, exercise phase, and recovery time). No changes in glucose levels, heart rate, and cardiac rhythm were detected. In comparison to baseline values, there is an increase: in lactate at the end of the exercise phase [EXER] (60’EXER), and in the recovery phase [RCT] at 30’RCT and 60’RCT, and cTnI at 60’RCT, 120’RCT, and 4hRCT. P wave duration was significantly higher at 60’EXER, 15’RCT, and 30’RCT, with no alterations in wave amplitude. QRS interval duration significantly increased at 30’RCT, and the ST segment presented a significant difference at 60’EXER, 15’RCT, and 60’RCT compared to the rest moment. The moderate alterations in lactate and cTnI and few alterations in the electrocardiographic and heart rate maintenance suggest the adaptation of rescue and recovery dogs to the type, intensity, and duration of search operation simulation performed.

The present study aimed at assessing the effects of combining 20 mg/kg S(+) ketamine with 25 μg/kg dexmedetomidine and 0.4 mg/kg butorphanol on the physiological parameters and anesthetic recovery time and score of eight captive scarlet macaw (Ara macao) specimens. These specimens were captured at the Marabá Zoobotanic Foundation (Fundação Zoobotânica de Marabá), Pará, using butterfly and mist nets, and subsequently subjected to the proposed protocol. The following physiological parameters were evaluated: heart rate (HR), respiratory rate (RR), saturation of peripheral oxygen (SpO2), body temperature (BT), and non-invasive blood pressure 5 min after drug administration (M0) and every 10 min thereafter (M1‒M5), with a total of 55 min of analysis of anesthetic effects. Glycemia was measured 5 min after drug administration and every 30 min thereafter. Anesthetic induction and recovery times were also determined. Among the parameters evaluated in this study, both HR and BT significantly decreased throughout the anesthetic period, with the lowest levels at 55 min after drug administration (M5). In contrast, RR did not significantly differ, and all animals remained stable, maintaining an RR close to a mean of 20 ± 8 cpm. Throughout the anesthetic period, SpO2 was 92 ± 5%, with no significant difference. The birds remained under spontaneous ventilation and without oxygen supplementation. Systolic, diastolic, and mean blood pressures remained stable, with no significant differences in any of these measurements. At M0 and M3, the glycemia decreased slightly, albeit with no significant difference justifying an adverse effect or even hypoglycemia. The anesthetic induction time, from M0 to decubitus, was 2.4 ± 0.7 min. The anesthetic recovery time, from M0 to effortless bipedal position and adequate phalangeal flexion, was 99.3 ± 32.4 min. The sedation was assessed as intense, and the anesthetic recovery was rated excellent in 62.5% and good in 37.5% of the animals.
研究了20 mg/kg S(+)氯胺酮与25 μg/kg右美托咪定和0.4 mg/kg丁托啡诺联用对8只人工养殖红金刚鹦鹉生理参数、麻醉恢复时间和评分的影响。这些标本是在par marab动物植物学基金会(funda o zoobot nica de marab)使用蝶网和雾网捕获的，随后接受了拟议的方案。在给药后5 min (M0)及之后每10 min (M1-M5)评估心率(HR)、呼吸频率(RR)、外周血氧饱和度(SpO2)、体温(BT)、无创血压等生理参数，共55 min分析麻醉效果。给药后5分钟测血糖，此后每30分钟测一次血糖。同时确定麻醉诱导和恢复时间。在本研究评估的参数中，HR和BT在整个麻醉期间均显著降低，在给药后55分钟达到最低水平(M5)。相比之下，RR没有显著差异，所有动物都保持稳定，保持接近20±8 cpm的平均RR。麻醉期间SpO2为92±5%，两组间无明显差异。这些鸟一直处于自发通气状态，没有补充氧气。收缩压、舒张压和平均血压保持稳定，这些测量值没有显著差异。在M0和M3时，血糖略有下降，但没有明显差异证明有不良反应甚至低血糖。麻醉诱导时间为2.4±0.7 min，麻醉恢复时间为99.3±32.4 min，麻醉恢复时间为99.3±32.4 min，镇静程度为强，62.5%的动物麻醉恢复为优，37.5%的动物麻醉恢复为良。

Studies on the interactions between the intestinal microbiome and its host have strengthened in the last decade. However, publications on this topic in dogs still need to be made available, reinforcing the need for new studies and literary data for consultation. Given this, this review aims to describe the intestinal microbiome and its interactions with the canine host, which can contribute to both health and morbid conditions in these animals. The definition of microbiome encompasses the collective genome of all microorganisms that live in a defined habitat (intestine). It is known that the dog’s intestinal microbiota is varied, composed of bacteria, archaea, viruses, fungi, and protozoa. Under normal conditions, there is commensalism between some of these microorganisms and the host, which promotes critical physiological relationships and interactions that contribute to homeostasis and the consequent health of the animal. With this in mind, it is expected that the disturbances associated with the microbiome will result in imbalances in this commensal relationship and thus precipitate the development of diseases and aggravation of other diseases, thus characterizing intestinal dysbiosis.

The corn snake (Pantherophis guttatus) is a non-venomous snake from the Colubridae family. The pair of scent glands is indispensable in the physiology of reproduction and defense of the species. This structure is located caudal to the cloaca. It is responsible for releasing a thick material based on lipids containing pheromones that perform functions associated with animal behavior and survival. This work aims to report infection by Morganella sp. in a scent gland in a female corn snake, evidencing the diagnosis and treatment. An increase in volume was seen in the final third, proximal to the cloaca, firm consistency, immobile, and approximately 4 cm long and painful to touch. Samples of the material were collected for bacterial culture and antibiogram examination, being positive for bacteria of the genus Morganella. Based on the result of the antibiogram, it was possible to determine the most appropriate therapeutic protocol, with the referral to perform the surgical procedure to remove the tissue compromised by the infection, remaining stable until the removal of the stitches 40 days after the procedure, with total surgical wound healing.

Gallbladder mucocele is characterized by hyperplasia of the gallbladder epithelium, increased mucus production, accumulation, and densification of the bile content, which can lead to biliary obstruction, necrosis, and rupture of the gallbladder wall. Its finding may be accidental or related to symptoms. A retrospective study (2016-2019) was carried out based on abdominal ultrasound examinations in dogs, correlating aspects of the gallbladder and biliary system in the mucocele with existing comorbidities. Thirty dogs diagnosed with biliary mucocele were evaluated, of which 46.66% had the disease at an early stage, and 53.33% showed a more advanced stage. Of these, 66.66% were related to endocrinopathies and hyperadrenocorticism. Signs of extrahepatic bile duct obstruction and biliary peritonitis were observed in two animals. Due to their potential risk of complications, follow-up ultrasound assessments are indicated in cases that opt for clinical treatment, not excluding the need for surgical intervention.
