Special Issue Information

Dear Colleagues,

We are excited to invite you to contribute to this Special Issue of Veterinary Sciences, entitled Trends in Nonhuman Primate Medicine & Care.

Nonhuman primate medicine and care is progressively becoming a dominant field in animal science, as welfare has attracted the growing attention of the international community at large, including zoo visitors, animal managers and all manner of others involved in the care of nonhuman primates. Updates and novelties about new pharmaceuticals, surgical and imaging techniques, treatment strategies of disorders and diseases, and nutrition, as well as knowledge of specific animal behavioral needs, are often initially described in human medicine and eventually become documented in nonhuman primate species. In some cases, these various modalities result in similarities and specificities in monkeys, and in other cases, result in totally different and sometimes unexpected outcomes. It is imperative that all of the results of these new trends, both positive and negative, are published, as laboratory animal professionals, wildlife experts and the general scientific community stand to learn from them, including negative results. Providing all trends in nonhuman primate medicines and care will improve welfare in captive, free-ranging and wild nonhuman primates.

This Special Issue will provide the latest updates in veterinary care in nonhuman primates, improving their welfare and enhancing their management.

The rhesus monkey (Macaca mulatta) is a widely used model in biomedical research because its anatomy and physiology bear many similarities to those of humans. Extensive knowledge of the anatomy of this nonhuman primate species is not only required for the correct interpretation of obtained research data but also valuable for the welfare of captive individuals housed in, e.g., zoos. As anatomical publications on the rhesus monkey are hardly available, outdated and provide only line drawings or black-and-white photographs, the anatomy of the rhesus monkey was readdressed in this study. The various anatomical structures are described in relation to each other topographically per hindlimb region. The hip region, the upper limb, the knee, the lower limb and the foot are described from various perspectives. The structures that are visible in the different layers, from the superficial to the deepest layer, were photographed. Although the anatomy of the hindlimbs of rhesus monkeys and humans are remarkably similar, various subtle dissimilarities have been observed. Consequently, an open-access publication that focuses on the anatomy of the rhesus monkey would be highly valued by both biomedical researchers and veterinarians. Full article

Since the rhesus monkey (Macaca mulatta) is genetically closely related to man, it is generally accepted that its anatomy and physiology are largely similar to that of humans. Consequently, this non-human primate is most commonly used as a model in biomedical research. Not only the validation of the obtained research data, but also the welfare of the captive rhesus monkeys are subject to thorough anatomical knowledge of this species. Unfortunately, anatomical literature on the rhesus monkey is scarce, outdated, and hardly available at present. Furthermore, its anatomy is only illustrated by means of line drawings or black-and-white photographs. Thus, the aim of this study was to describe the anatomy of the thoracic limb of the rhesus monkey topographically, studying the various anatomical structures in relation to each other. In this manuscript, the anatomy of the thoracic limb is described per region. The structures that are visible on the different layers, from the superficial to the deepest layer, are described both in text and in numerous color images. As expected, the anatomy of the rhesus monkey is almost identical to human anatomy. However, some striking differences have been identified. This supports the necessity for an extensive publication on the anatomy of the rhesus monkey. Full article

Evaluation of Anesthetic and Cardiorespiratory Effects after Intramuscular Administration of Three Different Doses of Telazol® in Common Marmosets (Callithrix jacchus)

Abstract
Marmosets’ small body size makes anesthesia challenging. Ideally, small volumes of drugs should be administered intramuscularly (i.m.). In addition, dose-dependent sedation and anesthesia are desirable properties for sedatives and anesthetics in marmosets. Telazol® (tiletamine and zolazepam) is highly concentrated, allowing the use [...] Read more.
Marmosets’ small body size makes anesthesia challenging. Ideally, small volumes of drugs should be administered intramuscularly (i.m.). In addition, dose-dependent sedation and anesthesia are desirable properties for sedatives and anesthetics in marmosets. Telazol® (tiletamine and zolazepam) is highly concentrated, allowing the use of small injection volumes and dose-dependent sedation and anesthesia. A randomized, blinded study with crossover design in ten healthy adult common marmosets (Callithrix jacchus) was performed to evaluate the anesthetic and cardiorespiratory effects of three doses of i.m. Telazol® (respectively, 5, 10, and 15 mg/kg). Depth of anesthesia, cardiorespiratory effects, and induction, immobilization, and recovery times were determined. A significant difference was observed in immobilization time between 5 and 15 mg/kg of Telazol®. In addition, 15 mg/kg of Telazol® resulted in increased recovery times compared to 5 mg/kg. The cardiorespiratory effects during the first 45 min of immobilization were within clinically acceptable limits. The pedal withdrawal reflex was the best indicator of the anesthetic depth.

Caloric restriction (CR) is an effective method to reduce overweight in captive non-human primates (NHPs). CR has been applied to individually- and pair-housed NHPs, but whether applying CR can be effective and safe in group-housed NHPs has not yet been assessed. This study investigates the effect of mild (20%) CR on adult overweight and biochemical parameters, immature growth, veterinary consultations, and reproductive success in multigenerational long-tailed macaque (Macaca fascicularis) breeding groups. Data were derived from anthropometric measurements and blood samples during yearly health checks, complemented with retrospective data on veterinary consultations and reproductive success. Adult body measures decreased after CR, with heavier individuals and females losing more weight compared to leaner individuals and males. CR lowered cholesterol levels in adults but had no overall effect on other biochemical parameters. Yet, biochemical parameters of individuals with high baseline values were reduced more compared to individuals with low baseline values. Immature growth, veterinary consultations and reproductive success were not influenced by CR. Thus, CR targeted the right individuals, i.e., overweight adults, and had no adverse effects on the variables examined in this study. This implies that mild CR can be a valuable overweight management strategy in group-housed NHPs. Full article

In this study, a review of available data and literature on the epidemiology and anamnesis of inguinal hernias in nonhuman primates, as well as on their clinical evaluation and surgical management, was conducted. Inguinal hernias are assumed to be relatively common in male nonhuman primates. Clinical signs are usually limited to a visible or palpable mass in the groin region without pain or systemic illness. Most hernias contain omentum. Careful monitoring is an acceptable treatment option for those animals. Size, the danger of incarceration, and the presence of strangulation are important factors when considering surgical repair. A strangulated inguinal hernia is an emergency, requiring prompt surgery to avoid tissue necrosis and death. Imaging techniques, as well as computed tomography (CT), ultrasonography, and magnetic resonance imaging (MRI), provide information about the anatomical characteristics of the suspected region, allowing for a diagnosis and treatment. An inguinal hernia repair can be performed with either open surgery or laparoscopic surgery. The hernia repair can be achieved by mesh or suture. Decisions regarding which repair technique to use depend on the surgeon′s skill level and preference. Complication and recurrence rates are generally low. The most common postsurgical complication is a recurrence of the hernia. Contraceptive measures are not indicated in breeders, as there is no known hereditary component, and the presence of hernia does not appear to affect fertility, nor does it predispose to occurrence, recurrence, or incarceration.
