“…One method of addressing buildup of plaque and tarter is to provide harder foods, like some insects; however, these foods may also create dental problems. Hard spikes on limbs of insects commonly fed to slender lorises in captivity, such as locusts and crickets, can damage the mucosa and introduce potentially pathogenic bacteria (Plesker & Schulze, , ). Dental abscesses were also common in these species, and trauma from spiky food is a potential cause of these issues.…”

“…Fuller et al () found that renal disease was a prevalent cause of death in lorises and pottos. Plesker and Schulze () reported polycystic nephropathy discovered on necropsy in a colony of slender lorises that had no clinical signs of renal disease. Alterations in kidney function and EPO production could explain erythrocyte abnormalities not observed clinically.…”

Sources of morbidity in lorises and pottos in North American zoos: A retrospective review, 1980–2010

Delineating patterns of morbidity can reveal management practices in need of reassessment to improve individual welfare, as well as population health and sustainability. We reviewed medical records from 38 North American zoological institutions for 276 slender lorises, slow lorises, and pottos born between January 1, 1980 and December 31, 2010. This sample included animals identified as 116 Nycticebus pygmaeus, 84 N. coucang, 48 Loris tardigradus tardigradus, 6 L.t. nordicus (now classified as L. lydekkerianus nordicus), and 22 Perodicticus potto. Taxonomy for lorises and pottos is developing, and two of these populations (N. coucang and P. potto) likely included hybrids and/or multiple species. Our focus was to examine trends based on species and age. Across all species, whole body disease events, abnormalities of bloodwork, and dental diseases were the most common sources of morbidity. Other major sources of morbidity varied by species and included trauma, respiratory disease, and ocular disease. A recent upsurge in research has informed feeding practices for slow lorises living in human care, and a similar, evidence-based approach is needed to improve diets for other species. Given the prevalence of trauma in this sample, social needs and reproductive management practices are also important areas for further investigation. Species-level health trends reveal risk factors for individual welfare that can guide husbandry practices in zoos, as well as in sanctuaries caring for the influx of lorises and pottos rescued from the growing wildlife trade.

“…A review of necropsies of Loris tardigradus housed at a German university revealed several cases of cholelithiosis or gallstones, all of which were composed of cholesterol and were speculated to be related to dietary factors like the presence of egg yolk and the reduced insect composition in the captive diet (Plesker & Schulze 2006). Of the 2 cases of gallstones in the present study, 1 occurred in L. t. tardigradus and 1 in L. t. nordicus, but none were reported for slow lorises or pottos.…”

Patterns of mortality in captive animals can reveal potentially problematic care practices or other risk factors that may negatively impact animal health and population sustainability. We reviewed death records (necropsy and/or histopathology reports) for 367 lorises and pottos born between 1980 and 2010 that were housed in 33 North American zoos and related facilities. Our sample included 20 Loris tardigradus nordicus, 72 L. t. tardigradus, 109 Nycticebus coucang, 133 N. pygmaeus, and 33 Perodicticus potto. In all 5 groups, neonates (animals < 30 d old) or geriatric animals accounted for the majority of death reports. Neonate deaths were most commonly attributed to stillbirth, trauma, and multi-systemic disease (septicemia or other infection). Animals that survived the first month of life were likely to live to adulthood or the geriatric stage. For all species, the most commonly cited causes of death were renal disease, multi-systemic illness, and trauma. Over 50% of all the animals studied displayed some renal pathology upon postmortem analysis. Across species, other organ systems in which > 20% of animals showed signs of disease included the cardiovascular and hemolymphatic, endocrine and metabolic, gastrointestinal, and immunologic systems. Our results indicate that reducing neonatal mortality is a major priority for sustaining these species in captivity, and common practices for managing groups during the perinatal period should be carefully scrutinized. Other areas in need of further investigation are environmental contributions to neoplastic and infectious disease, and dietary contributions to chronic degenerative conditions.

“…22 Polycystic kidney disease (PKD) is one of the most common genetic diseases in humans 10 and has frequently been reported in a variety of domestic, laboratory, and nondomestic species. 7,9,13,14,20 In humans, the diagnosis of PKD is reached when at least three cysts distributed between both kidneys are identified. 5 In domestic animals, most cases are considered to be congenital, and there is some evidence that the condition is heritable, with increased frequency in certain families of cats (Persian cats), dogs (Cairn terriers), pigs, and monkeys.…”
