Item Aspects of the morphological, radiographic and ultrasonographic anatomy of the red panda (Ailurus fulgens) and ring-tailed lemur (Lemur Catta)(University of Pretoria, 2015-07) Makungu, Modesta L. J.The red panda and ring-tailed lemur are species, which are commonly kept in zoological gardens. The red panda and ring-tailed lemur are classified as vulnerable and endangered, respectively, by the International Union for Conservation of Nature and Natural Resources. The aim of this study was to describe the normal radiographic thoracic anatomy, radiographic and ultrasonographic abdominal anatomy as well as the normal morphology of the pelvis, thoracic and hind limb in captive red pandas and ring-tailed lemurs as a reference for clinical use. Radiography and ultrasonography were performed in adult captive red pandas and ring-tailed lemurs during annual health examinations. Bone specimens of adult red pandas and ring-tailed lemurs were used for gross osteological study. The morphology of the pelvis, thoracic and hind limb of the red panda and ring-tailed lemur supported the presence of strong flexor and supinator muscles and flexibility of limb joints, which are important in arboreal quadrupedal locomotion. However, the scapula of the ring-tailed lemur is modified for both arboreal and terrestrial quadrupedal locomotion. Additionally, the morphology of the pelvis and hind limb of the ring-tailed lemur showed locomotor adaptation for jumping. Normal radiographic and ultrasonographic reference ranges for thoracic structures and abdominal organs were established and ratios were calculated. Knowledge of the normal morphology, radiographic and ultrasonographic anatomy of the red panda and ring-tailed lemur should prove useful in the diagnosis of diseases and for routine health examinations.Item Morphology of the pelvis and Hind limb of the red panda (Ailurus fulgens) evidenced by gross Osteology, radiography and computed tomography(Anatomia Histologia Embryologia, 2015-12) Makungu, M.; du Plessis, W. M.; Groenewald, H. B.; Barrows, M.; Koeppel, K. N.The red panda (Ailurus fulgens) is a quadrupedal arboreal animal primarily distributed in the Himalayas and southern China. It is a species commonly kept in zoological collections. This study was carried out to describe the morphology of the pelvis and hind limb of the red panda evidenced by gross osteology, radiography and computed tomography as a reference for clinical use and identification of skeletons. Radiography of the pelvis and right hind limb was performed in nine and seven animals, respectively. Radiographic findings were correlated with bone specimens from three adult animals. Computed tomography of the torso and hind limb was performed in one animal. The pelvic bone had a wide ventromedial surface of the ilium. The trochlea of the femur was wide and shallow. The patella was similar to that seen in feline species. The medial fabella was not seen radiographically in any animal. The cochlea grooves of the tibia were shallow with a poorly defined intermediate ridge. The trochlea of the talus was shallow and presented with an almost flattened medial ridge. The tarsal sesamoid bone was always present. The lateral process of the base of the fifth metatarsal (MT) bone was directed laterally. The MT bones were widely spaced. The morphology of the pelvis and hind limb of the red panda indicated flexibility of the pelvis and hind limb joints as an adaptation to an arboreal quadrupedal lifestyle.Item Polycystic kidneys in the Red Panda (Ailurus fulgens)(Journal of Zoo and Wildlife Medicine, 2013-09) Makungu, M.; du Plessis, W. M.; Barrows, M.; Koeppel, K. N.; Groenewald, H. B.An intact adult male 14.3-yr-old red panda (Ailurus fulgens) presented for health examination with a history of slowly progressing loss of body condition. Abdominal radiographs revealed a truncated abdomen with poor serosal abdominal detail and multiple areas of spondylosis with some collapsed intervertebral disc spaces. On computed tomography, multiple ovoid hypoattenuating lesions were seen in the left and right kidneys. Gross pathology and histopathology revealed multiple cystic lesions in the kidneys concurrent with pancreatic cysts on histopathology. To the best of the authors’ knowledge, polycystic kidneys have not been reported in this species.Item Radiographic abdominal anatomy in captive red pandas (Ailurus fulgens)(Journal of Zoo and Wildlife Medicine, 2018-03) Makungu, M.; du Plessis, W. M.; Barrows, M.; Groenewald, H. B.; Koeppel, K. N.The red panda (Ailurus fulgens) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The aim of this study was to describe the normal radiographic abdominal anatomy in red pandas to provide guidance for clinical use. Radiography of the abdomen was performed in nine captive red pandas during their annual health examinations. Seven of nine animals had six lumbar vertebrae. The sacrum consisted mainly (8/9) of three fused segments. Hypaxial muscles were easily seen in animals weighing 5 kg and above. The pylorus was located to the right of the midline and cranially to the fundus in 8/9 individuals. Bunching of small intestine in the right central abdomen occurred in animals weighing 6 kg and above. The spleen was prominent. Knowledge of the normal radiographic abdominal anatomy of red pandas is important in the diagnosis of diseases and in routine health examinations.Item Radiographic Thoracic Anatomy of the Red Pand (Ailurus fulgens)(Journal of Zoo and Wildlife Medicine, 2016-09) Makungu, M.; du Plessis, W. M.; Barrows, M.; Groenewald, H. B.; Koeppel, K. N.The red panda (Ailurus fulgens) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The natural distribution of the red panda is in the Himalayas and southern China. Thoracic diseases such as dirofilariasis, hypertrophic cardiomyopathy, tracheal obstruction, lung worm infestation, and pneumonia have been reported in the red panda. The aim of this study was to describe the normal radiographic thoracic anatomy of captive red pandas as a species-specific reference for routine health examinations and clinical cases. Right lateral (RL) and dorsoventral (DV) inspiratory phase views of the thorax were obtained in 11 adult captive red pandas. Measurements were made and ratios calculated to establish reference ranges for the mean vertebral heart score on the RL (8.34 6 0.25) and DV (8.78 6 0.34) views and the mean ratios of the caudal vena cava diameter to the vertebral body length above tracheal bifurcation (0.67 6 0.05) and tracheal diameter to the width of the third rib (2.75 6 0.24). The majority of animals (10/11) had 14 thoracic vertebrae, except for one animal that had 15 thoracic vertebrae. Rudimentary clavicles were seen in 3/11 animals. The ovoid, oblique cardiac silhouette was more horizontally positioned and elongated in older animals. A redundant aortic arch was seen in the oldest animal. The trachea was seen with mineralized cartilage rings in all animals. The carina was clearly seen in the majority of animals (10/11). Variations exist in the normal radiographic thoracic anatomy of different species. Knowledge of the normal radiographic thoracic anatomy of the red panda should prove useful for routine health examinations and in the diagnosis of thoracic diseases.Item Thoracic Limb Morphology of the Red panda (Ailurus fulgens) evidenced by Osteology and Radiography(Onderstepoort Journal of Veterinary Research, 2015-07-15) Makungu, M.; du Plessis, W. M.; Barrows, M.; Koeppel, K. J.; Groenewald, H. B.The red panda (Ailurus fulgens) is distributed primarily in the Himalayas and southern China. It is classified as a vulnerable species by the International Union for Conservation of Nature. The aim of this study was to describe the normal osteology and radiographic anatomy of the thoracic limb of the red panda. Radiography of the right thoracic limb was performed in seven captive adult red pandas. Radiographic findings were correlated with bone specimens from three adult animals. The scapula was wide craniocaudally and presented with a large area for the origin of the teres major muscle. The square-shaped major tubercle did not extend proximal to the head of the humerus. The medial epicondyle was prominent. A supracondylar foramen was present. The radial tuberosity and sesamoid bone for the abductor digiti I longus were prominent. The accessory carpal bone was directed palmarolaterally. Metacarpal bones were widely spread. The thoracic limb morphology of the red panda evidenced by osteology and radiography indicated flexibility of the thoracic limb joints and well-developed flexor and supinator muscles, which are important in arboreal quadrupedal locomotion. Knowledge gained during this study may prove useful in identifying skeletal material or remains and diagnosing musculoskeletal diseases and injuries of the thoracic limb.
