This study aimed to investigate whether the power Doppler ultrasonography can distinguish between singleton and twin pregnancies on day 50 by determining placentome vascularization in Kıvırcık ewes. A total of 67 ewes were enrolled for the study. Pregnancy was confirmed on day 23 at 51 of 67 sheep that were synchronized. The groups were formed based on the presence of single (Group S; n = 25 ewes) or twin (Group T; n = 26 ewes) foetuses. Placentome diameters on day 50 were not different between the groups (P > 0.05). Placentome blood flow area and the mean, minimum and maximum amount of coloured pixels were unrelated to groups. However, the relationship between the parameters that reflect the placentome vascularity in Group S was statistically detectable. The mean amount of coloured pixels in Group S tended to be moderately correlated with the mean amount of coloured pixels in Group T. There was a positive correlation in the mean, maximum, and area of the coloured pixels in twin pregnancies. In conclusion, power flow Doppler ultrasonography can be used to determine placentome blood perfusion but the number of offspring on day 50 could not be determined by placentome vascularity.

Bovine spongiform encephalopathy (BSE) is a progressive neurodegenerative disorder in cattle that poses risks to public health and has economic consequences. The shadow of prion protein encoded by the shadow of prion protein (SPRN) gene affects prion disease progression. A 12-base-pair indel polymorphism in the SPRN gene has been implicated in BSE susceptibility in Polish cattle. Building upon our previous research, we aimed to investigate the SPRN gene polymorphisms in Jeju black cattle - a Korean native breed with distinct genetic features and compared them with those in Hanwoo and Korean Holstein. Our findings reveal that the Jeju black cattle SPRN gene, with only two synonymous single nucleotide polymorphisms, has lower genetic diversity than that in Hanwoo and Korean Holstein. Moreover, we contrasted the distribution of c.199_210delGCCGCGGCGGGG (67_70delAAAG) polymorphisms in the SPRN gene between BSE-infected Polish cattle and Korean cattle to assess BSE susceptibility. The results suggest that Jeju black and Korean Holstein demonstrate a higher genetic potential for BSE resistance compared to the Hanwoo breed. To the best of our knowledge, this study provides the first report of the SPRN gene in Jeju black cattle, along with a comparative analysis of SPRN gene polymorphisms across three Korean cattle breeds.

Rodents (Mammalia: Rodentia) are among the ubiquitous hosts of Giardia duodenalis, as they can harbour at least six assemblages of this species, including the zoonotic assemblages A and B. However, studies targeting a broad spectrum of rodents and rabbits sampled in the same region are scarce, even in Europe. During this study, 164 samples were collected from five rodent species and rabbits in five locations in Hungary, to examine the presence of G. duodenalis with traditional parasitological and molecular methods. Parasitological analysis revealed the presence of cysts in 58.3% of asymptomatic Norway rats and 27.6% of chinchillas. Three degus were also found Giardia-infected (prevalence: 16.7%) using flotation technique. With PCR targeting three genetic markers, 3.2% of the samples showed positivity, whereas a rate of 21.9% prevalence was detected with flotation. The PCR products of five samples could be DNA sequenced. Phylogenetic analysis based on the partial sequences of the beta-giardin gene revealed the presence of assemblages B and G in rats. In addition, assemblage E was detected in a beaver, while assemblage B was present in a chinchilla. The results show that synanthropic rodent species have different epidemiological roles in the study region, depending on the prevalence of shedding Giardia cysts or harbouring zoonotic variants of G. duodenalis. Moreover, our findings confirm that pet rodents may pose a risk for zoonotic Giardia-transmission.

啮齿类动物(哺乳纲:啮齿目)是杜氏贾第鞭毛虫无处不在的宿主之一,因为它们至少能寄生该物种的六种组合,包括人畜共患病的组合 A 和 B。在这项研究中,我们从匈牙利五个地方的五种啮齿类动物和兔子身上采集了 164 份样本,采用传统的寄生虫学和分子方法来检测 G. duodenalis 的存在。寄生虫学分析表明,58.3% 的无症状挪威鼠和 27.6% 的龙猫体内存在囊肿。利用浮选技术,还发现三只degus感染了贾第虫(感染率:16.7%)。利用针对三个基因标记的 PCR 技术,3.2% 的样本显示阳性,而利用浮选技术则检测到 21.9% 的感染率。五个样本的 PCR 产物可以进行 DNA 测序。根据 beta-giardin 基因的部分序列进行的系统进化分析表明,大鼠中存在 B 和 G 群体。此外,还在海狸中发现了 E 组合,而在栗鼠中发现了 B 组合。研究结果表明,根据贾第虫包囊脱落或携带杜氏贾第虫人畜共患病变异体的流行程度,啮齿类动物在研究地区具有不同的流行病学作用。此外,我们的研究结果证实,宠物啮齿类动物可能构成贾第虫人畜共患传播的风险。

Light is one of the factors affecting physiological functions in living things. In the present study, reproductive functions of male rats exposed to different wavelengths of light were evaluated. For this purpose, a total of 56 male Sprague Dawley rats were used in 7 groups (n = 8 per group). Rats were exposed to light spectrum with different wavelengths for 63 days. It was observed that malondialdehyde levels were lower in the orange (2.77 ± 0.16 nmol*mL-1), red (4.27 ± 0.17 nmol*mL-1), yellow (5.14 ± 0.15 nmol*mL-1) and green (5.56 ± 0.40 nmol*mL-1) coloured light group compared to the other groups [purple (7.07 ± 0.96 nmol*mL-1), blue (7.52 ± 0.89 nmol*mL-1), white (8.59 ± 1.20 nmol*mL-1)] (P < 0.001). The lowest glutathione levels were observed in purple (86.82 ± 1.63 nmol mL-1), blue (101.25 ± 3.61 nmol*mL-1), yellow (105.44 ± 1.70 nmol*mL-1) and green (108.11 ± 0.51 nmol*mL-1) coloured groups, respectively. The lowest sperm motility percentage was found in blue (29.16 ± 11.40), purple (56.25 ± 3.36), green (62.50 ± 4.91) and white (69.58 ± 5.51) coloured light groups compared to the other groups (P < 0.001). Epididymal sperm density decreased significantly in rats exposed to purple, orange and blue light (P < 0.001). The abnormal sperm ratio was higher in the blue and white light group compared to the other groups (P < 0.001). Histological examinations showed that tubulus seminiferus contortus diameter and germinal cell thickness decreased significantly in the purple light treatment (P < 0.001). As a summary, the application of purple and blue light has negative effects on the reproductive function in rats.

Histopathological alterations caused by Thaparocleidus vistulensis (Siwak, 1932) on the European catfish Silurus glanis Linnaeus, 1758 were investigated by histopathology and scanning electron microscopy (SEM). The pathological effects of T. vistulensis on the gills of the European catfish were mainly related to the attachment sites of the parasite to its host, but damage also affected adjacent structures. The primary attachment relies on the anchors at the opisthaptor which commonly adheres both superficially and deeply, into the basal region between adjacent secondary lamellae. At the attachment sites, the haptoral disc of the parasites formed deep concave cup-like depressions on the surface of the gill lamellae. Deep anchor penetration occasionally distorted the extracellular cartilaginous matrix and induced a marked proliferation of epithelial tissue. Epithelial hyperplasia leading to lamellar fusion and subsequent extravasated erythrocytes in the gill lamellae was also observed. The damage caused by the parasites also led to the fusion of lamellae at the tips of the heavily infected gill filaments, forming club-like structures. Epithelial eosinophilic granular cells were frequently observed at the attachment sites. The pathological changes caused by this monopisthocotylan parasite frame the need to implement effective management strategies for controlling T. vistulensis infections in farmed European catfish populations.

Objective: To identify associations between the occurrence of sacrocaudal fusion and the potential morphology of certain hind limb bones in actively racing greyhounds.

Methods: The calcaneus, talus and patella from each hind limb were collected from 94 male and 77 female mature greyhound cadavers and grouped into four groups; right or left bones from greyhounds with a standard or fused sacrum. The measurements were recorded for the following parameters: body mass of the greyhound, mass, length, and width of the right and left calcanei, tali and patellae.

Results: A fused sacrum (4 sacral vertebrae) was present in 41% of specimens. The right and left calcanei, tali and patellae in greyhounds with a standard or fused sacrum were anatomically similar. Overall, left to right asymmetry was found, in the width of calcaneus (P < 0.01) and the talus (P < 0.05) and the length of calcaneus (P < 0.001) all these being larger in bones from the left hind limbs. Comparing bones from dogs with a fused or unfused sacrum showed that the right calcaneus length (P < 0.05) was significantly less than the left in those greyhounds with standard sacrum; the right calcaneus width was significantly less (P < 0.01) than the left in those with a fused sacrum. There were no significant differences in the means of measurements of bones between greyhounds with a standard and those with a fused sacrum except for the mass of the right (95% CI 0.22 to 1.10, P < 0.01) and left (95% CI 0.18 to 1.04, P < 0.01) calcaneus which were heavier in greyhounds with a fused sacrum than those with a standard sacrum.

Conclusion: In a population of greyhounds that race on anticlockwise tracks, the left calcaneus was wider and longer than the right and the left talus was wider. This asymmetry was more significant in dogs with sacrocaudal fusion and those dogs had more massive calcanei than dogs with standard sacrums, suggesting a difference in the way these bones were loaded in dogs with sacrocaudal fusion compared to dogs with the standard sacral anatomy.

Oral nerve blocks are an indispensable technique for pre-emptive pain management in various veterinary procedures, including tooth extractions. Local anaesthetic drugs are considered the safest and the most effective agents to inhibit oral pain. Recently, tramadol was used as an adjuvant to local anaesthetics to increase the duration of analgesia. The aim of this study was to compare the effect of maxillary nerve block induced by lidocaine or lidocaine-tramadol on perioperative pain in dogs undergoing upper fourth premolar extraction. A randomized blinded clinical study was conducted over five months involving sixteen animals divided into two groups, Group L (8 animals, Group Lidocaine) and Group LT (8 animals, Group Lidocaine-Tramadol). Both drugs provided effective pain control during and after surgical intervention, but lidocaine-tramadol resulted in longer analgesia than lidocaine alone. These findings suggest that the maxillary nerve block with lidocaine-tramadol can ensure adequate and prolonged pain control in dogs undergoing dental extraction. Although these are preliminary results, tramadol showed promising effects as a potential drug to use during oral surgery in association to local anaesthetics.

The anti-Müllerian hormone (AMH) is a granulosa cell-derived hormone that has been associated with female fertility and reflects the population of growing follicles. This study aimed to evaluate the average concentration of AMH in Lipizzaner mares, as well as to determine the relationship between AMH concentration and follicle number and size. We also investigated the relationship between the age of mares and their AMH levels. The possible effect of seasonality of AMH levels was also assessed. Twenty-three mares between 6 and 24 years of age were included in the experiment. Mares were divided into two groups: Group 1 included mares aged 6 - 15 years (n = 11), while Group 2 included individuals older than 15 years of age (n = 12). Venous blood was collected and ovarian activity was monitored parallelly by transrectal ultrasonography. Serum AMH concentrations varied widely between the two different groups. AMH concentrations were significantly lower in old mares than in younger animals. A positive relationship was detected between AMH concentration and the number of medium-sized follicles (P = 0.022), large follicles (P = 0.016) and the total follicle count (P = 0.026). No seasonal effect was detected.

勒氏激素(AMH)是一种颗粒细胞衍生的激素,与女性生育能力有关,反映了卵泡生长的数量。本研究旨在评估利比扎马AMH的平均浓度,并确定AMH浓度与毛囊数量和大小之间的关系。我们还调查了母马年龄与其AMH水平之间的关系。还评估了AMH水平的季节性可能的影响。23匹6至24岁的母马参与了这项实验。母马分为两组:1组6 ~ 15岁母马(n = 11), 2组15岁以上母马(n = 12)。经直肠超声同时监测静脉血和卵巢活动。两组血清AMH浓度差异很大。老年母马的AMH浓度明显低于年轻母马。AMH浓度与中等卵泡数(P = 0.022)、大卵泡数(P = 0.016)和总卵泡数(P = 0.026)呈正相关。未发现季节效应。

This study aimed to contribute to the conservation of red pandas by improving the understanding of their oestrus cycle through examining urinary hormone changes during their breeding season. To minimize stress associated with blood sample collection, we used urine samples Sex hormone levels were measured over six months in pregnant and nonpregnant red pandas, to help understand changes in oestrogen concentrations during oestrus, post-mating progesterone concentrations and differences in ceruloplasmin concentrations. The results of the study revealed that female red pandas are polyoestrous, with a second oestrogen peak after mating. Progesterone changed in a cascading fashion, peaking and then gradually declining. Successfully mated females showed higher levels of progesterone than unsuccessfully mated females, which had no peak in progesterone after mating. Ceruloplasmin was measured to confirm pregnancy, but its value as a pregnancy diagnostic factor was not confirmed. These results provide significant insights into the reproductive physiology of red pandas and lay the foundation for additional research towards improving the management and breeding strategies for this threatened species.

本研究旨在通过研究小熊猫繁殖季节的泌尿激素变化,提高对其发情周期的了解,为保护小熊猫做出贡献。为了减少血液采集带来的压力,我们使用了尿液样本,测量了怀孕和未怀孕的小熊猫在六个月内的性激素水平,以帮助了解发情期雌激素浓度、交配后黄体酮浓度和铜蓝蛋白浓度的变化。研究结果显示,雌性小熊猫是多发期的,交配后会出现第二次雌激素高峰。孕激素以层叠的方式变化,达到峰值,然后逐渐下降。交配成功的雌鼠孕酮水平高于交配失败的雌鼠,而交配后雌鼠孕酮水平没有高峰。测定铜蓝蛋白以确认妊娠,但其作为妊娠诊断因素的价值尚未得到证实。这些结果为研究小熊猫的生殖生理学提供了重要的见解,并为进一步研究改善这一濒危物种的管理和繁殖策略奠定了基础。

In this publication various serum biochemistry and haematology parameters were determined from blood samples obtained from captive adult individuals of an exotic quail species, the mountain quail (Oreortyx pictus, Douglas, 1829). Venipuncture was performed in the second half of the breeding season from six roosters (males) and seven hens (females). During the examination, in addition to the haematological elements, basic parameters of serum enzyme levels, the products of protein metabolism, uric acid and the most important ions were monitored. The results are presented as a reference in future diagnostic tests for certain diseases. The blood parameters of the bird species examined in this study have not yet been published earlier.

本出版物测定了外来鹌鹑物种山鹑(Oreortyx pictus, Douglas, 1829)圈养成年个体血液样本中的各种血清生化和血液学参数。在繁殖季节的后半期,对 6 只公鸡(雄性)和 7 只母鸡(雌性)进行了静脉穿刺。在检查过程中,除血液元素外,还监测了血清酶水平、蛋白质代谢产物、尿酸和最重要离子的基本参数。这些结果可作为今后某些疾病诊断测试的参考。本研究中检测的鸟类的血液参数尚未发表过。
