Objective-To assess dual-energy x-ray absorptiometry (DXA) for evaluating effects of diet and environment on bone mineral density in Hermann's tortoises (Testudo hermanni). Animals-26 Hermann's tortoises within 1 month after hatching. Procedures-Group 1 was housed in an artificial setting and fed naturally growing vegetation. Group 2 was housed in an artificial setting and fed vegetables grown for human consumption. Group 3 was maintained in an outside enclosure and fed naturally growing vegetation. After 10 months, pyramidal growth, body weight, and adverse conditions were assessed. Bone mineral density (BMD) of the axial and appendicular skeleton, shell, vertebral column, and pelvis was measured via DXA. Results-Group 2 had the highest mean +/- SD body weight (65.42 +/- 30.85 g), followed by group 1 (51.08 +/- 22.92 g) and group 3 (35.74 +/- 7.13 g). Mean BMD of the shell varied significantly among groups (group 1, 0.05 +/- 0.03 g/cm2•m; group 2, 0.09 +/- 0.15 g/cm2•m; and group 3, undetectable). The BMD of the axial and appendicular skeleton, vertebral column, and pelvis did not differ significantly among groups. Pyramidal growth was highest in group 1 and not evident in group 3. Conclusions and Clinical Relevance-Tortoises raised in artificial conditions did not have deficits in BMD, compared with results for outdoor-housed hibernating tortoises. Supplemental calcium was apparently not necessary when an adequate photothermal habitat and plant-based diet were provided. Higher BMD of captive-raised tortoises was morphologically associated with a higher incidence of pyramidal growth in captive-raised groups.

Objective-To determine whether tepoxalin alters kidney function in dogs with chronic kidney disease (CKD). Animals-16 dogs with CKD (International Renal Interest Society stage 2 or 3) and osteoarthritis. Procedures-Kidney function was assessed via serum biochemical analysis, urinalysis, urine protein-to-creatinine concentration ratio, urine γ-glutamyl transpeptidase-to-creatinine concentration ratio, iohexol plasma clearance, and indirect blood pressure measurement twice before treatment. Dogs received tepoxalin (10 mg/kg, PO, q 24 h) for 28 days (acute phase; n = 16) and an additional 6 months (chronic phase; 10). Recheck examinations were performed weekly (acute phase) and at 1, 3, and 6 months (chronic phase). Kidney function variables were analyzed via repeated-measures ANOVA. Results-There was no difference over time for any variables in dogs completing both phases of the study. Adverse drug events (ADEs) resulting in discontinuation of tepoxalin administration included increased serum creatinine concentration (1 dog; week 1), collapse (1 dog; week 1), increased liver enzyme activities (1 dog; week 4), vomiting and diarrhea (1 dog; week 8), hematochezia (1 dog; week 24), and gastrointestinal ulceration or perforation (1 dog; week 26). Preexisting medical conditions and concomitant drug use may have contributed to ADEs. Kidney function was not affected in the latter 5 dogs. Discontinuation of tepoxalin administration stabilized kidney function in the former dog and resolved the ADEs in 4 of the 5 latter dogs. Conclusions and Clinical Relevance-Tepoxalin may be used, with appropriate monitoring, in dogs with International Renal Interest Society stage 2 or 3 CKD and osteoarthritis.

2013
Smith, Courtney C. | Cebra, Christopher K. | Heidel, Jerry R. | Stang, Bernadette V.
Objective—To compare numbers of L cells in intestinal samples and blood concentrations of glucagon-like peptide (GLP)-1 between neonatal and mature alpacas. Sample—Intestinal samples from carcasses of 4 suckling crias and 4 postweaning alpacas for immunohistochemical analysis and blood samples from 32 suckling crias and 19 healthy adult alpacas for an ELISA. Procedures—Immunohistochemical staining was conducted in accordance with Oregon State University Veterinary Diagnostic Laboratory standard procedures with a rabbit polyclonal anti–GLP-1 primary antibody. Stained cells with staining results in ileal tissue were counted in 20 fields by 2 investigators, and the mean value was calculated. For quantification of GLP-1 concentrations, blood samples were collected into tubes containing a dipeptidyl peptidase-4 inhibitor. Plasma samples were tested in duplicate with a commercial GLP-1 ELISA validated for use in alpacas. Results—Counts of stained cells (mean ± SD, 50 ± 18 cells) and plasma GLP-1 concentrations (median, 0.086 ng/mL; interquartile range, 0.061 to 0.144 ng/mL) were higher for suckling alpacas than for postsuckling alpacas (stained cells, 26 ± 4 cells; plasma GLP-1 concentration, median, 0.034 ng/mL; interquartile range, 0.015 to 0.048 ng/mL). Conclusions and Clinical Relevance—Older alpacas had lower numbers of L cells in intestinal tissues and lower blood concentrations of GLP-1 than those in neonates. These findings suggested that there may be a decrease in the contribution of GLP-1 to insulin production in adult alpacas, compared with the contribution in neonates.

Ramey, Andrew M. | Spackman, Erica | Yeh, Jung-Yong | Fujita, Go | Konishi, Kan | Uchida, Kiyoshi | Reed, John A. | Wilcox, Benjamin R. | Brown, Justin D. | Stallknecht, David E.
Blood samples from 105 northern pintails (Anas acuta) captured on Hokkaido, Japan were tested for antibodies to avian influenza virus (AIV), Japanese encephalitis virus (JEV), and West Nile virus (WNV) to assess possible involvement of this species in the spread of economically important and potentially zoonotic pathogens. Antibodies to AIV were detected in 64 of 105 samples (61%). Of the 64 positives, 95% and 81% inhibited agglutination of two different H5 AIV antigens (H5N1 and H5N9), respectively. Antibodies to JEV and WNV were detected in five (5%) and none of the samples, respectively. Results provide evidence for prior exposure of migrating northern pintails to H5 AIV which could have implications for viral shedding and disease occurrence. Results also provide evidence for limited involvement of this species in the transmission and spread of flaviviruses during spring migration.

Objective—To determine whether different suture configurations could improve the biomechanical performance of 3 suture materials used with bone anchors. Samples—3 suture materials (60-lb test nylon leader line, size 2 polyblend polyethylene composite suture, and 150-lb test ultrahigh–molecular weight spun polyethylene). Procedures—Each suture material was looped through the eyelet of a metallic bone anchor and constructs were evaluated by use of an acute uniaxial load. Three configurations were tested for each suture material: single stranded (SS), double stranded (DS), and single stranded plus plastic insert (SSP). Force at failure, extension at failure, force at 3 mm of extension, stiffness, and site of failure of the suture were recorded for each test. Results—For all sutures, the DS configuration was the stiffest and yielded significantly higher forces at failure and forces at 3 mm of extension. The SS configuration had the lowest forces at failure. The SSP configuration yielded greater forces at failure for all suture materials, compared with the SS configuration, with a comparable stiffness. All sutures failed at the eyelet in the SS and DS configurations. In the SSP configuration, 60-lb test nylon leader line and 150-lb test ultrahigh-molecular weight spun polyethylene failed at the eyelet less frequently than did the polyblend composite suture. Conclusions and Clinical Relevance—Among the tested constructs, a DS suture configuration used in combination with the metallic bone anchor gave the best biomechanical results for all suture materials. Considering that the SSP configuration yielded greater forces at failure, compared with the SS configuration, covering metallic edges in bone anchors with softer materials might protect sutures and result in increased forces at failure.

2013
Kam, K. Y. | Yong, C. K. | Guo, Y. H.
PCV-2 associated disease and related losses occur commonly in high health status herds. With the advent of PCV-2 vaccines, these losses can be successfully reduced. In this study, there was a significant reduction (48%) in the mortality rate of the vaccinated pigs when
compared to the non-vaccinated pigs. Vaccination was conducted at day 21. In the vaccinated group, mortality was reduced from 5.25 % to 2.73%. This data indicates that the implementation of a PCV2 vaccination program can reduce the mortality rate of high health status pigs in Malaysia.

A detailed post mortem was carried out on a male Bryde’s whale
Balaenoptera brydei, a cetacean of suborder Mysticetes, with a wide geographical distribution. The stranded whale, weighing approximately 3.5 metric tons was found beached along the Pekan Nenasi River, Pahang in East Coast of Malaysia facing South China Sea. Gross pathology showed severe hemorrhagic gastritis, probably
due to foreign material found compacted in the multichamber stomach, severe congestion in the various vital organs due to toxemia, and severe endoparasite burden in the intestine. Thousands of Digeneans
were found in both the caecum and colon. Morphological identification was carried out on these parasites which were identified as Ogmogaster species. As co parasites, the acathocephalan worms Falsifilicollis species was also detected in the large intestine. Histological examination indicated severe bronchointerstitial embolic pneumonia, chronic interstitial
hemorrhages, intra alveolar septa thickening in lung tissue; chronic hepatic interstitial hemorrhage, hepatocellular and centrilobular degeneration on the liver tissue; renal tubular and glomerular
necrosis in kidney tissue; splenic necrosis and hemorrhages; intestinal mucosal layer necrosis and severe intestinal villi necrosis. The continuing survival of Bryde’s species whale is precarious, because of disregard for appropriate measures for their
conservation and to conduct appropriate study for the cause of death.
