A novel siadenovirus was identified in the Sulawesi tortoise (Indotestudo forsteni). A group of 105 Sulawesi tortoises was obtained by the Turtle Survival Alliance. Many of the tortoises were in poor health. Clinical signs included anorexia, lethargy, mucosal ulcerations and palatine erosions of the oral cavity, nasal and ocular discharge, and diarrhea. Initial diagnostic tests included fecal testing for parasites, complete blood count and plasma biochemical analysis, mycoplasma serology, and polymerase chain reaction (PCR) testing for intranuclear coccidia and chelonian herpesvirus. Treatment included administration of antibiotics, antiparasitic medications, parenteral fluids, and nutritional support. Tissue samples from animals that died were submitted for histopathologic evaluation. Histopathologic examination revealed systemic inflammation and necrosis associated with intranuclear inclusions consistent with a systemic viral infection in 35 tortoises out of 50 examined. Fecal testing results and histopathologic findings revealed intestinal and hepatic amoebiasis and nematodiasis in 31 animals. Two of 5 tortoises tested by PCR were positive for Chlamydophila sp. Aeromonas hydrophila and Escherichia coli were cultured from multiple organs of 2 animals. The mycoplasma serology and PCR results for intranuclear coccidia and chelonian herpesvirus were negative. Polymerase chain reaction testing of tissues, plasma, and choanal/cloacal samples from 41 out of 42 tortoises tested were positive for an adenovirus, which was characterized by sequence analysis and molecular phylogenetic inference as a novel adenovirus of the genus Siadenovirus. The present report details the clinical and anatomic pathologic findings associated with systemic infection of Sulawesi tortoises by this novel Siadenovirus, which extends the known reptilian adenoviruses to the chelonians and extends the known genera of reptilian Adenoviridae beyond Atadenovirus to include the genus Siadenovirus.

Three immature Sunda wrinkled hornbills (Aceros corrugatus) were diagnosed postmortem with proventricular spirurid nematodiasis. Concurrent severe disseminated larval granulomatosis in other visceral organs was considered contributory to mortality in each case. Clinical signs of nematodiasis were vague but generally consisted of weight loss, anorexia, and lethargy. Frequent antemortem fecal examinations were negative for spirurid eggs. In these present cases, based on routine histopathology, both prophylactic and empirically based therapeutic anthelmintic treatments had no evident benefit in the elimination of the proventricular nematodes. Spirurid nematodiasis may be an important cause of mortality in young hornbills.

A male ball python (Python regius) and a female blue tongue skink (Tiliqua spp.) of unknown age were evaluated for anorexia, lethargy, excessive shedding, corneal opacity (python), and weight loss (skink) of approximately three weeks' duration. These animals represented the worst affected animals from a private herpetarium where many animals exhibited similar signs. At necropsy, the python had bilateral corneal opacity and scattered moderate dysecdysis. The skink had mild dysecdysis, poor body condition, moderate intestinal nematodiasis, and mild liver atrophy. Microscopic evaluation revealed epidermal erosion and ulceration, with severe epidermal basal cell degeneration and necrosis, and superficial dermatitis (python and skink). Severe bilateral ulcerative keratoconjunctivitis with bacterial colonization was noted in the ball python. Microscopic findings within the skin and eyes were suggestive of ultraviolet (UV) radiation damage or of photodermatitis and photokeratoconjunctivitis. Removal of the recently installed new lamps from the terrariums of the surviving reptiles resulted in resolution of clinical signs. Evaluation of a sample lamp of the type associated with these cases revealed an extremely high UV output, including very-short-wavelength UVB, neither found in natural sunlight nor emitted by several other UVB lamps unassociated with photokeratoconjunctivitis. Exposure to high-intensity and/or inappropriate wavelengths of UV radiation may be associated with significant morbidity, and even mortality, in reptiles. Veterinarians who are presented with reptiles with ocular and/or cutaneous disease of unapparent cause should fully evaluate the specifics of the vivarium light sources. Further research is needed to determine the characteristics of appropriate and of toxic UV light for reptiles kept in captivity.

We report a remarkably good outcome in a 14-month-old boy with early clinical diagnosis and aggressive empirical treatment of neural larva migrans caused by the raccoon roundworm Baylisascaris procyonis. He presented with fever, meningismus, lethargy, irritability and asymmetric spastic extremity weakness. Early findings of marked blood and cerebrospinal fluid eosinophilia and of diffuse white matter signal abnormality in the brain and spinal cord on MRI suggested a parasitic encephalomyelitis. Rapid presumptive treatment with albendazole and high-dose steroids halted progression of clinical signs. The diagnosis was confirmed by 2 sequential enzyme-linked immunosorbent assay studies positive for B procyonis serum immunoglobulin G and by Western blot. Field examination with soil sampling yielded infective Baylisascaris eggs. Repeat MRI 3 months later showed atrophy and diffuse, chronic white matter abnormalities, discordant with the marked clinical improvement in this interval. At 10 months, residual neurologic deficits included subtle paraparesis and moderate language delay. This case is the first in which spinal involvement in human Baylisascaris infection was clinically suspected and confirmed by neuroimaging. Importantly, early diagnosis and aggressive treatment of Baylisascaris meningo-encephalitis and myelitis with albendazole and high-dose steroids likely contributed to the good outcome in this patient, in contrast with previous reports.
