2014年夏,在甘肃省肃北县马鬃山镇进行了野生动物资源调查,于明水村采集到8号鬣蜥科(Agamidae)爬行动物标本,经鉴定为新疆岩蜥阿尔泰亚种(Laudakia stoliczkana altaica),为新疆岩蜥在甘肃省的首次纪录。通过形态特征、生态习性及地理分布对其与新疆岩蜥指名亚种(Laudakia stoliczkana stoliczkana)和塔里木岩蜥(Laudakia tarimensis)做了对比研究,发现其尾部每3环1节(仅基部2~3节为4环1节),栖息生境为干燥裸露的石山,分布于天山山脉以北至阿尔泰山、戈壁阿尔泰山周缘,与另外两者明显不同。最后对新疆岩蜥物种分化的原因和分布界线进行了讨论。 相似文献

A 13‐year‐old male spur‐thighed tortoise (Testudo graeca) was presented with anorexia, apathy, and prolapse of penile tissue. Ultrasonography revealed a large heterogeneous mass in the coelomic cavity, and fine‐needle aspiration demonstrated sperm. Magnetic resonance imaging showed a sharply defined mass originating from the left testis. Appearance and signal intensities were similar to those reported in testicular neoplasms in humans, in particular sharing similarities with seminomas. Necropsy results and histopathological findings were consistent with a seminoma. To the authors’ knowledge this is the first report of the diagnosis of testicular neoplasia in a reptile using imaging techniques. 相似文献

AIM: To describe the microscopic and immunohistochemical findings in a case of pulmonary hyalohyphomycosis in a Kemp's ridley sea turtle (Lepidochelys kempi). METHODS: Samples of lung, liver and kidney from a stranded, dead Kemp's ridley sea turtle were routinely processed for histopathological studies. Two monoclonal antibodies that reacted specifically with antigens of Aspergillus spp and the Mucorales (Zygomycetes) group, and a panel of polyclonal antibodies raised against Aspergillus fumigatus, Candida albicans, Geotrichum candidum, Fusarium solani, and Scedosporium apiospermum were used for immunohistochemical or immunofluorescence staining. RESULTS: Histologically, a severe multifocal granulomatous pneumonia associated with fungal infection was diagnosed. All hyphae were identified as Fusarium spp because a strong and uniform reactivity was obtained only with a heterologously-absorbed polyclonal antibody raised against somatic antigens of Fusarium solani. CONCLUSIONS: Fusarium spp should be included in the differential diagnosis of mycotic pneumonia in Kemp's ridley sea turtles. CLINICAL RELEVANCE: This is the first report of a pulmonary mycotic infection in a sea turtle diagnosed using immunohistochemistry. Wildlife rehabilitators and pathologists should be aware of the availability of immunohistochemical techniques for identifying fungi in sea turtles. 相似文献

ObjectiveTo characterise the anaesthetic effects of alfaxalone administered intramuscularly (IM) at 10, 20, and 30 mg kg?1.Study designProspective, randomized cross-over study.AnimalsTen juvenile green iguanas (Iguana iguana) of mean body weight (±SD) 480 ± 134 g.MethodsAlfaxalone was administered IM in the triceps of both thoracic limbs. Times for anaesthetic induction, plateau and recovery periods were recorded. Skeletal muscle tone of the jaw, neck, thoracic limbs, pelvic limbs, and tail was scored. The palpebral, corneal and righting reflexes, and the response to painful stimuli were also assessed. Pulse rate and respiratory rate were recorded. Comparisons between different dosages and over time were made using anova.ResultsTimes are given for 10, 20 and 30 mg kg?1 dosages respectively: mean time to maximal effect was 7.7 ± 2.2, 5.4 ± 1.7 and 3.9 ± 1.2 minutes; duration of the plateau phase was 11.3 ± 3.8, 22.1 ± 6.5 and 39.1 ± 11.5 minutes; recovery time was 10 ± 2.4, 17.5 ± 8.6 and 25 ± 7.1 minutes; and total anaesthetic duration was 29 ± 35.7, 45 ± 8.2 and 68 ± 9.8 minutes. Endotracheal intubation was possible in 40% of the subjects given 10 mg kg?1 and in 100% subjects given both 20 and 30 mg kg?1. Loss of response to a painful stimulus was seen in 0/10, 8/10 and 9/10 animals at 10, 20, and 30 mg kg?1 respectively. There was an initial dose-dependent depression of respiration followed by a significant increase in frequency over time. In contrast, pulse rates decreased by 20% over the duration of the anaesthetic events.Conclusions and clinical relevanceIntramuscular administration of alfaxalone is a simple, rapid and reliable means of achieving relatively brief sedation or anaesthesia in healthy green iguanas. A dosage of 10 mg kg?1 provides light sedation, appropriate for examination and venipuncture; 20 mg kg?1 provides a level suitable for minor procedures or for endotracheal intubation and supplementation with inhalational anaesthesia; 30 mg kg?1 produces an anaesthetic plane suitable for surgical procedures of limited duration (up to 40 minutes). 相似文献
