Objective The contribute of recurring seizures to the progression of epileptogenesis is debated. Seizure-induced brain damage is not conclusively demonstrated both in humans and in animal models of epilepsy. We evaluated the expression of brain injury biomarkers on post-surgical brain tissue obtained from 20 patients with frequent seizures and a long history of drug-resistant focal epilepsy. Methods The expression patterns of specific glial, neuronal and inflammatory molecules was evaluated by immunohistochemistry in the core of type II focal cortical dysplasias (FCD-II), at the FCD boundary (perilesion) and in the adjacent normal-appearing area included in the epileptogenic region...

We evaluated a widely used culture-based method for detection of livestock-associated meticillin-resistant Staphylococcus aureus (LA-MRSA) in samples collected from pigs and the environment inside pig stables in Denmark and Norway. Selective enrichment in tryptic soy broth containing cefoxitin and aztreonam led to a high ratio of false-negative results (26%; 57/221). On this basis, we recommend reconsidering the use of selective enrichment for detection of LA-MRSA in animal and environmental samples.

Hypoderma tarandi causes myiasis in reindeer and caribou (Rangifer tarandus spp.) in most northern hemisphere regions where these animals live. We report a series of 39 human myiasis cases caused by H. tarandi in Norway from 2011 to 2016. Thirty-two were residents of Finnmark, the northernmost county of Norway, one a visitor to Finnmark, and six lived in other counties of Norway where reindeer live. Clinical manifestations involved migratory dermal swellings of the face and head, enlargement of regional lymph nodes, and periorbital oedema, with or without eosinophilia...

Several adenoviruses are known to cause severe disease in veterinary species. Recent evidence suggests that canine adenovirus type 1 (CAV-1) persists in the tissues of healthy red foxes (Vulpes vulpes), which may be a source of infection for susceptible species. It was hypothesized that mustelids native to the UK, including pine martens (Martes martes) and Eurasian otters (Lutra lutra), may also be persistently infected with adenoviruses. Based on high-throughput sequencing and additional Sanger sequencing, a novel Aviadenovirus, tentatively named marten adenovirus type 1 (MAdV-1), was detected in pine marten tissues...

Isoflurane gas anesthesia is often used for immobilization of prairie dogs in field studies, laboratory research, and veterinary clinical purposes. The goals of this prospective study were to evaluate the effects of sternal versus right lateral recumbency on trends of selected physiologic parameters during isoflurane anesthesia in black-tailed prairie dogs ( Cynomys ludovicianus ). Fourteen adult, zoo-housed black-tailed prairie dogs were tested during the study. Animals were anesthetized using isoflurane and randomly placed in either sternal or right lateral recumbency to evaluate changes in trends of physiologic parameters, measured selectively every 30 min throughout a 60-min anesthesia period...

Enrofloxacin is known to cause retinal toxicity in domestic cats. The hallmark lesion of enrofloxacin-associated retinal toxicity in domestic cats is thinning of the outer nuclear layer of the retina. Enrofloxacin is commonly used to treat bacterial infections in nondomestic felids because of its action against a wide spectrum of bacteria and the ability for it to be given orally. No previous studies have investigated the potential retinal toxicity of enrofloxacin in nondomestic felids. This retrospective study evaluated 81 eyes from 14 lions ( Panthera leo ) and 33 tigers ( Panthera tigris ) that had been enucleated or collected postmortem...

Squamous cell carcinoma (SCC) is well documented in snow leopards ( Uncia uncia ) and most common locations are oral, facial, or pedal. These two cases illustrate an unusual auricular presentation, which is more often reported in white domestic cats. The animals were aged and presented clinical signs of otitis such as head shaking and ear scratching. Clinical examinations showed auricular canal masses with chronic purulent otitis. In both cases, clinical deterioration led to euthanasia and histology of the ear canal was consistent with SCC and showed numerous vascular emboli...

The International Species Information System has set forth an extensive database of reference intervals for zoologic species, allowing veterinarians and game park officials to distinguish normal health parameters from underlying disease processes in captive wildlife. However, several recent studies comparing reference values from captive and free-ranging animals have found significant variation between populations, necessitating the development of separate reference intervals in free-ranging wildlife to aid in the interpretation of health data...

A female North American porcupine ( Erethizon dorsatum ) was evaluated for a unilateral pedal crusting and alopecic dermatopathy. Fungal culture and histopathology testing revealed Microsporum gypseum dermatophytosis. Treatment with topical miconazole was initiated and then discontinued after 9 days and changed to oral terbinafine. Twenty-eight days after initial examination, clinical signs were improving, and fungal cultures of the front foot, muzzle, and noninfected area along the dorsum were negative for M...

Intranuclear coccidiosis of tortoises (TINC) has been described in association with systemic disease in various species of tortoises. TINC has been detected in numerous tortoises from the United States, but there are only a few reports from tropical tortoises in Germany and no reports from Asia. Using a real-time polymerase chain reaction assay, samples from 1,011 tortoises were screened for the presence of TINC. Samples originated from animals kept in captivity in Europe and in China. Coccidia were detected in a total of 27 chelonians (2...

Although the administration of blood and blood products can be lifesaving, transfusions in exotic species are less common because of the lack of knowledge of a species' blood groups, the availability of species-specific donors, and possible adverse effects. Recently, blood groups were elucidated in great apes; however, few reports have been published regarding actual transfusion situations in these species. This information is critical because poorly executed transfusions can compromise already weakened patients or result in the death of the recipient...

Tumors are infrequently reported in skunks, with only a few case reports published in the literature. Chylothorax associated with mediastinal lymphoma was diagnosed in a captive 7-yr-old male striped skunk ( Mephitis mephitis ). The animal presented with anorexia and apathy. Supportive care and prednisolone improved the animal's clinical status for 2 wk preceding its death. Histopathology supported the clinical findings, and the tumor was classified as a mediastinal non-Hodgkin lymphoma, stage 2b, which has not been documented in the literature...

Squamous cell carcinomas (SCCs) are common oronasal tumors in nonhuman primates. In this study, 11 cases of oronasal SCC in François' langurs ( Trachypithecus francoisi ) are described. Five initial cases were discovered on review of the North American François' langur studbook, with a potential familial pattern observed. The studbook was used to identify related individuals, and records were requested for review. Six additional cases were documented, and samples from all cases were submitted for microscopic review, as well as polymerase chain reaction (PCR), immunohistochemistry (IHC), and in situ hybridization (ISH), for generic papillomaviruses and PCR for herpesviruses because either virus may cause SCC in humans and other nonhuman primates...

A 5-mo-old female Rothschild's giraffe ( Giraffa camelopardalis rothschildi) presented for regurgitation. Esophagoscopy at 24 wk of age revealed a markedly dilated cranial esophagus with a tight stricture at the level of the heart base consistent with a vascular ring anomaly. Surgical exploration confirmed persistent right fourth aortic arch with ductus originating from left subclavian artery at its junction with the aorta and left subclavian artery. The patent ductus arteriosus was surgically ligated. The procedure was complicated by limited surgical access and vascular friability resulting in uncontrollable hemorrhage, and the animal was euthanatized...

Thei-STAT® portable clinical analyzer (PCA) provides patient-side results for hematologic, biochemical, and blood gas values when immediate results are desired. This analyzer is commonly used in nondomestic animals; however, validation of this method in comparison with traditional benchtop methods should be performed for each species. In this study, the i-STAT PCA was compared with the Radiometer ABL 800 Flex benchtop analyzer using 24 heparinized whole blood samples obtained from healthy E. maximus . In addition, the effect of sample storage was evaluated on the i-STAT PCA...
