ations.Studies to assess wildlife health commonly evaluate clinical pathology changes, immune responses, pathogen presence, and contaminant exposure, but novel modalities are needed to characterize the unique physiologic responses of reptiles. Lactate is an indicator of hypoperfusion and/or anaerobic respiration and can be quickly and easily measured using a point-of-care analyzer. This study evaluated baseline blood lactate concentrations in free-living eastern box turtles (Terrapene carolina carolina, n = 116) using a point of care analyzer and then determined the effect of handling time, physical examination (PE) abnormalities, and quantitative polymerase chain reaction pathogen detection (Terrapene herpesvirus 1, Mycoplasma sp., Terrapene adenovirus) on lactate concentrations. Blood lactate concentrations were higher in turtles with Terrapene herpesvirus 1 (n = 11), quiet mentation, and increased packed cell volume (P less then 0.05). Lactate concentrations increased between initial capture and PE, with peak values reaching 129 min after capture. Lactate at PE was positively associated with baseline lactate concentrations. Turtles with Terrapene herpesvirus 1 may have alterations in blood flow, oxygen delivery, or activity patterns, driving increases in baseline lactate. Increased handling time likely leads to more escape behaviors and/or breath holding, causing turtles to undergo anaerobic metabolism and raising lactate concentrations. Overall, lactate measured by a point of care analyzer shows variability caused by capture and health factors in eastern box turtles and may be a useful adjunctive diagnostic test in this species after full methodologic validation.While electrophoresis is considered the standard method for evaluation of protein concentrations as a result of its direct measurement, albumin is often quantified with biochemical assays. Many laboratory-based chemistry analyzers and clinic-based point-of-care analyzers use the dye bromocresol green (BCG) for the quantitation of albumin. Several studies have shown that albumin concentrations obtained by the standard (BCG) dye-binding method are significantly different from those obtained by protein electrophoresis in avian species and chelonia. The goal of this study was to compare plasma albumin concentrations obtained by the BCG method with those derived from electrophoresis in bearded dragons (Pogona vitticeps). Thirty-six heparinized plasma samples were obtained from 13 clinically healthy male bearded dragons. Albumin was quantified by protein electrophoresis and by the BCG dye-binding method. The two methods were significantly different (P less then 0.0001, paired t-test; P less then 0.0001, Wilcoxon signed-rank test), with the BCG measurement always equal to or higher than the electrophoretic result. The measurements from both methods were significantly correlated (r = 0.8634, P less then 0.0001), but concordance between the two techniques was poor. The Bland-Altman plot appeared to show a greater difference between the two measurements with lower albumin values and lesser difference with higher values. These results indicate that bearded dragon plasma albumin concentration measurements obtained by the BCG dye-binding method are unreliable when compared to those obtained with electrophoresis, suggesting that albumin should be measured by protein electrophoresis for health assessment in bearded dragons.Native to Southeast Asia, the Sunda pangolin (Manis javanica) is critically endangered largely because of poorly regulated wildlife trade, consumptive practices, and use in traditional Chinese medicine. Efforts to rescue and rehabilitate animals confiscated from the illegal trade are complicated by a general lack of knowledge surrounding the normal health and disease processes unique to the species. To provide clinical reference intervals for normal health states of Sunda pangolins, biochemical parameters were determined from rescued individuals in Vietnam that had undergone a 14-day observation period and met a set of criteria for release back into the wild. Blood samples were collected from 42 apparently healthy Sunda pangolins while anesthetized or awake. Packed cell volume (PCV) and total solids (TS) were determined manually, and serum biochemistry values were determined in-house with a benchtop analyzer. this website Additional biochemical and mineral parameters not included in the primary panel were determined from a subset of 10 pangolins through an external diagnostic laboratory. Overall reference intervals were calculated for PCV and TS (n = 29) and for standard serum biochemistry parameters (n = 42). Females and males demonstrated significant variation with respect to body mass, potassium (K+), and phosphorus, whereas age was a significant source of variation in alkaline phosphatase. Seasonal variation in glucose (GLU), creatinine (CRE), total proteins, sodium, calcium, and K+ was also observed. Comparisons between anesthetized and awake pangolins demonstrated significant variation in GLU, CRE, and K+. The parameters determined in this study can serve as a clinical reference for ex situ Sunda pangolin conservation efforts. In the context of wildlife rehabilitation, serial bloodwork allows for continued monitoring of patient health and should inform decision making regarding release readiness and timing.Amoebiasis is a significant protozoal disease of reptiles causing nonspecific clinical signs including diarrhea, anorexia, and lethargy. It frequently results in acute death. Investigation of the pathophysiology of amoebiasis in reptiles has been hampered by the inability to accurately identify amoeba to the species level using conventional techniques. This study reviewed reptile medical records from the Wildlife Conservation Society's archives from 1998 to 2017. Amoebae were identified histologically in 54 cases in 31 different species. Of these, amoebiasis was the cause of death in 32 (18 chelonians, 7 lizards, and 7 snakes), a significant co-morbidity in 14 (six chelonians, two lizards, and six snakes), and seen incidentally in eight cases (one chelonian, six lizards, and one snake). Relocation from one enclosure to another was also evaluated and 65% of cases had been moved within 180 days of death (median 46 days). Frozen tissue samples from 19 of these cases were tested via an Entamoeba (genus-specific) polymerase chain reaction (PCR) assay. PCR products were sequenced and Entamoeba species were identified. Six individuals were positive for Entamoeba invadens (three chelonians, two snakes, one lizard), two for Entamoeba ranarum (both snakes), and one for Entamoeba terrapinae (chelonian); the other 10 cases were negative via PCR. Entamoeba ranarum has typically been considered a disease of amphibians with only one report of disease in a snake. Entamoeba terrapinae has only been reported without associated disease in chelonians. These results suggest that amoebiasis is a complicated and nuanced disease of reptiles, and warrants additional study.Adenoviruses have been regularly detected in squamate reptiles; evidence of infection in chelonians is described much less frequently. The adenoviruses found in turtles and tortoises have been genetically diverse, and have included members of the genus Siadenovirus, a proposed testadenovirus genus, and, in a single case, an Atadenovirus. In this study, samples from 949 chelonians submitted to a diagnostic laboratory were screened for the presence of adenoviruses by polymerase chain reaction (PCR) targeting a portion of the DNA polymerase gene. Adenoviruses were detected in 22 (2.3%) chelonians of different species. Adenovirus-positive species included Hermann's tortoises (Testudo hermanni), spur-thighed tortoises (T. graeca), Horsfield's tortoises (T. horsfieldii), sliders (Trachemys spp.), box turtles (Terrapene spp.) and a black pond turtle (Geochlemys hamiltonii). Sequencing and phylogenetic analyses of the obtained PCR products revealed that the majority of the detected adenoviruses (72.7%) cluster with members of the proposed testadenovirus genus, while the rest (27.3%) cluster with the atadenoviruses. This study significantly expands the known host range of both the proposed testadenoviruses and the atadenoviruses in different chelonian species and families.Spirurids, specifically the Rictularia, Chitwoodspirura, Streptopharagus, and Protospirura genera, have been reported to parasitize all nonhuman primate taxa. Spirurid pathogenesis in nonhuman primates has not been reported frequently; however, Protospirura muricola has been associated with serious gastric pathologies, including gastric perforation. This study was a retrospective study of 38 vervet monkey (Chlorocebus pygerythrus) necropsies performed in a primate sanctuary that houses captive orphaned or injured wild-born vervet monkeys. Individuals were categorized according to their age, sex, and body condition score to investigate the relationships between these factors and parasite presence. This study identified P. muricola in 47.37% of the necropsied carcasses. Regarding individual factors associated with P. muricola infection, no significant differences between males and females were observed; however, relationships between parasite presence and poor body condition and advanced host age were observed. Furthermore, one monkey death was potentially directly related to spirurid pathogenic action, because the individual showed gastric perforation.Sarcocystosis was diagnosed in a captive flock of thick-billed parrots (Rhynchopsitta pachyrhyncha) at the Wildlife Conservation Society's Queens Zoo. Since the index case in 2005, 45% of mortalities in birds over 30 days of age were due to sarcocystosis. Sarcocystis falcatula was repeatedly identified as the causative agent. The disease predominantly affected younger adult parrots. Administration of antiparasitic medications prior to development of respiratory signs prolonged life in infected birds, but disease was fatal until utilization of a three-drug combination (pyrimethamine, trimethoprim-sulfamethoxazole, and ponazuril). This protocol may require in excess of 6 mo of therapy to achieve clinical resolution of active disease. Plasma creatine kinase activity was found to be the most useful test in diagnosing infection and monitoring response to therapy. Polymerase chain reaction (PCR) for apicomplexan organisms on antemortem whole blood, blood smears, or dried blood spots helped confirm suspected cases, but due to the poor sensitivity was sometimes misleading when assessing response to therapy or resolution of clinical disease. Preventive measures, focusing on exclusion and removal of Virginia opossums (Didelphis virginiana) from zoo grounds failed to curtail the occurrence of sarcocystosis in the flock. Other preventative steps, such as modification of feeding stations to exclude potential arthropod paratenic hosts and prophylaxis trials with diclazuril, appeared to successfully mitigate new infections. Given the diagnostic and therapeutic challenges, prevention of exposure to S. falcatula is essential to ex-situ conservation efforts for thick-billed parrots.Piroplasms, which include Babesia spp. and Theileria spp., are protozoan parasites carried by ticks and commonly cause disease in animals and humans. Those caused by Babesia spp. manifest as fever, anemia, and hemoglobinuria, while Theileria spp. can lead to high fever, diarrhea, and lymphadenopathy. Recently, Theileria capreoli and an undescribed Babesia sp. were detected for the first time in sika deer (Cervus nippon yesoensis) from Hokkaido; however, there is limited information available on their epidemiology in Japan. Here, a touchdown polymerase chain reaction and reverse line blot hybridization were used to perform an epidemiological survey of T. capreoli and Babesia sp. using blood samples from 82 sika deer in Hokkaido, Japan. This was followed by partial sequencing and phylogenetic analysis of the 18S rRNA and β-tubulin genes to characterize both piroplasm species. A total of 43 (52.4%) and 3 (3.7%) of the sika deer were positive for T. capreoli and Babesia sp., respectively. The β-tubulin gene partial sequences for Babesia sp.
