A 16-year-old, 7.4 kg, castrated male Cocker Spaniel presenting anorexia and weight loss was referred due to a splenic mass, and total splenectomy was performed to resolve clinical signs. Following surgery, the dog developed mild hyperkalemia (6.27 mmol/L) without any clinical symptoms. Further investigations were conducted to determine the cause of hyperkalemia. The serum-plasma potassium difference was measured (1.05 mmol/L), and pseudohyperkalemia was diagnosed. The cause of pseudohyperkalemia was considered as thrombocytosis after splenectomy. The dog did not receive any specific treatment to lower blood potassium. To our knowledge, we report the first case of post-splenectomy pseudohyperkalemia in a dog.

With the increasing population of companion dogs, the social cost derived from their behavioral problems is increasing. Therefore, it is important to understand the environment to provide experience for dogs via interactions with their owners to prevent and solve these problems. The parenting behavior of dog owners as an environmental factor has a profound impact on the behavior development of dogs, as does the parenting behavior on children. Therefore, this study aimed to develop a scale to assess the dog owner’s parenting behavior. Exploratory factor analysis involving 300 participants resulted in a scale with four subscales, Positive Education, Involvement of Socialization, Intimacy, and Stable Responses, and 19 items. Confirmatory factor analysis was then performed to verify its reliability and validity. The result of parenting behaviors assessed by this scale was significantly different between a group with dogs with problematic behavior (n = 141) and those without (n = 159). Overall, a dog owner’s parenting behavior involves affection and control aspects, but the role required specifically in the control aspect is distinguished from the parenting behavior with children. The findings in the present study will provide dog owners with effective education that will help prevent dogs from developing behavioral problems.

Vaccination against Newcastle disease (ND) is the most effective means of controlling the disease, and these vaccines are commercialized only after their safety and effectiveness have been verified through tests that comply with Korean Standards of National Lot Release for Veterinary Biologics. This study investigated whether a relatively convenient and safe serological test can be used in place of the challenge test using highly virulent ND virus. Hemagglutination inhibition (HI) assay and enzyme-linked immunosorbent assay (ELISA) were considered positive of log2 2 or more and cutoff value of 200 or more, respectively, in both live and inactivated vaccines. However, when the antibody levels of the live and inactivated vaccines induced using the Ulster 2C, KBNP-C4152R2L, and K148/08 strains were compared, the antibody titers for inactivated vaccines were significantly higher than those for live vaccines in both the HI assay and ELISA. A strong positive correlation was observed between HI and ELISA antibody titers. The live vaccines corresponded to a survival rates of ≥ 80% and the inactivated vaccines corresponded to 100% survival rates. This study confirmed that standard efficacy tests can serve as serological tests, and can replace the challenge test and that the vaccine approval process can be improved.

Anah, S.A. | Anah, S.A. | Al-Khalidy, K.A.H.
In the study, zinc oxide nanoparticles (ZNOPs) at concentrations of 20, 40, and 60 mg/kg were tested for their antimicrobial action against the oocysts of Eimeria tenella. The oocysts of E. tenella were isolated from the feces of broilers received at the veterinary hospital in Diwaniyah Province and initially diagnosed by compound optical microscopy. The oocysts were confirmed molecularly by polymerase chain reaction targeting the ITS1 gene with a molecular weight of 409 bp. The results in the first week showed that ZNOP concentrations of 20 and 40 mg/kg possess various activities against E. tenella, while 60 mg/kg was the most effective in reducing excreted oocysts compared to the positive control and amprolium group, along with the appearance of mild symptoms and a mortality rate of 0.8%. In the second week of infection, excreted oocysts and mortality rates generally decreased in all treated groups. A comparison of all groups showed that the 60 mg/kg ZNOP-treated group had a significantly lower number of excreted oocysts, and all birds in this group recovered during the second week of infection. These findings revealed the prospect of using ZNOPs against E. tenella in challenging situations of the appearance of resistance to anticoccidial agents.

Splenic myelolipoma is a rare tumor in dogs with an unclear origin. A male 13-yearold Schnauzer dog was presented because of a bump on the left side of the abdomen. Clinical examination and abdominal ultrasound revealed a mass in the spleen. A total splenectomy was carried out, and histopathology revealed a splenic myelolipoma. Before surgery, the patient showed high serum alanine aminotransferase levels, which returned to normal eight months after the resection. Unfortunately, the postoperative follow-up showed increased serum cholesterol and triglyceride levels, suggesting liver compromise. This is the first report of a splenic myelolipoma in Colombia.

A 12-year-old intact male Dalmatian dog presented hyporexia and vomiting for 1 week. Blood analysis revealed increased liver enzyme activity. Histopathological examination of the liver confirmed chronic hepatitis with fibrosis and necrosis. Copper staining revealed marked copper accumulation (2,770 ppm; normal range, 200 to 400 ppm), prominent in the centrilobular region, and compatible with copper-associated chronic hepatitis. However, copper metabolism domain containing 1 (COMMD1) mutation predisposing to copper accumulation in the liver tissue was not identified. The dog received medications but died 1 month after first visit. This is the first case of primary copper-associated hepatitis without COMMD1 mutation in a Dalmatian dog in South Korea.

Newcastle Disease (ND) is a highly infectious disease of poultry causing huge economic loss to the poultry farmers. Newcastle Disease is controlled by vaccination of commercial or backyard poultry using inactivated or live ND vaccines. In the present study, safety and humoral antibody response in birds vaccinated with Newcastle disease virus oral pellet vaccine (NDV OPV) was studied in field conditions. A total of 300 backyard poultry (n=100/ farm) from three different farms were vaccinated with NDV OPV. The vaccinated birds were monitored for any adverse reactions or mortality up to 28 days post vaccination (dpv). There were no untoward reactions or mortality in the vaccinated birds in all the three farms up to 28 dpv. Blood samples (n=8/farm) were collected randomly from vaccinated birds on 0 and 28 dpv in each farm and were subjected to heamagglutination inhibition (HI) test. The mean HI titre was 66, 56 and 25 in farm 1, farm 2 and farm 3 respectively at 28 dpv. All the vaccinated birds had protective HI titre of ≥16 at 28 days post vaccination. In conclusion, Newcastle disease virus oral pellet vaccine (NDV OPV) is safe and induces good protective humoral antibody response and can be used to control ND in backyard poultry.

Curcumin derived from curcuma longa has been reported for its anti-cancer activity, but low bioavailability limits the therapeutic potential of curcumin. In this study curcumin and solid lipid nanocurcumin were tested for its therapeutic use and methotrexate was used as the standard drug. Methotrexate at a dose rate of 3.5mg/kg bodyweight and curcumin and nanocurcumin at a dose rate of 100 and 50 mg/kg bodyweight were evaluated in Dalton’s Ascites Lymphoma-bearing mice by assessing various hematobiochemical parameters. Hematological parameters were estimated using auto hematology analyzer and biochemical parameters with automatic serum biochemical analyzer. Dalton’s Ascites Lymphoma-bearing mice showed reduction in RBC count and amount of Hb and increased leukocyte count with neutrophilia in comparison with normal control group. The tumor control group also showed elevated levels of ALT, AST and ALP while albumin and total protein levels decreased in serum. Treatment with curcumin and nanocurcumin showed significant increase in RBC and Hb count as well as decrease in WBC count. There was a significant decrease ALT, AST and ALP and increase in albumin and total protein levels. Precisely curcumin and nanocurcumin showed significant influence in the restoration of various hematobiochemical parameters.
