Korean Journal of Veterinary Research.2014;54(2):127-129.

A male, 3.5 month old Pomeranian dog was diagnosed with a natural infection of Crenosoma (C.) vulpis in Daejeon, Korea. First stage larvae of C. vulpis were detected by fecal examination using the Baermann technique. Thoracic radiographs revealed mild, pervasive bronchial infiltration of the lung. Enumeration of larvae via the McMaster technique revealed 1,600 larvae per gram of feces. The dog was treated with mebendazole, and clinical symptoms were resolved 2 weeks post-treatment, as indicated by the subject presenting fecal tests negative for C. vulpis.

Korean Journal of Veterinary Research.2014;54(2):123-126.

An 11-year-old castrated male Maltese weighing 3.6 kg and a 12-year-old intact female Shih-tzu weighing 6.5 kg were admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with decompensatory congestive heart failure. Diuretic resistance was suspected due to long term diuretic therapy with furosemide. However, the patients improved after the furosemide treatment was changed to torsemide, demonstrating the benefits of application of torsemide to treat diuretic resistance caused by long term use of furosemide. These findings suggest that torsemide should be applied for treatment of diuretic resistance caused by long term use of furosemide.

The treatment of lower extremity defects with severe proliferative tissue using an adjustable horizontal mattress suture in a Tosa dog.

Suyoung HEO ; Namsoo KIM

Korean Journal of Veterinary Research.2014;54(2):121-122.

A 2-year-old male Tosa was admitted for treatment of a non-healing wound on the right forelimb. Skin tests were unremarkable; however, the lesion contained severe proliferative tissue. Surgical treatment was conducted due to the extensive skin defect and granulation tissue present. Following removal of the proliferative tissue, the wound was closed using the adjustable horizontal mattress suture method with multiple punctate relaxing incisions. The proliferative tissue healed completely after the surgical treatment. This technique can be considered an alternative treatment for the proliferative tissue when conditions require a skin graft or flap after surgical treatment.

Resistance and control of cypermethrin and chlorpyrifos as acaricide for control of hard tick Haemaphysalis longicornis (acari: ixodidae).

Myung Jo YOU

Korean Journal of Veterinary Research.2014;54(2):117-120.

Chemotherapeutic treatment is still the foundation of tick control programs. This study investigated the acaricidal efficacy of cypermethrin alone and in combination with chlorpyrifos against Haemaphysalis (H.) longicornis. Unfed larval ticks were exposed to 0.1, 1.0, and 10 mg/mL cypermethrin for 60 min, after which the acaricidal efficacy was examined based on tick mortality. All compounds showed similar suppression curves, with the best control being achieved by cypermethrin and chlorpyrifos (1 : 1 ratio) at 10 mg/mL. Effective cypermethrin concentrations for tick control were two to seven times higher than the recommended doses, indicating resistance by H. longicornis.

Korean Journal of Veterinary Research.2014;54(2):113-115.

Salmonella are causative agents of gastroenteritis and systemic disease in animals. The invA gene was selected as a target sequence of loop-mediated isothermal amplification (LAMP) assay for diagnosis of Salmonella infection. The detection limits for broth dilution, spiked feces and enrichment were 10(4), 10(5) and 10(2) CFUs/mL, respectively. The LAMP assay developed in the present study may be a reliable method for detection of Salmonella spp. in pig feces.

Four viruses showing cytopathic effects in MDBK cells were isolated from brains of cattle showing downer cattle syndrome in 2012. The isolates were confirmed to belong to the genus Rubulavirus of the subfamily Paramyxovirinae. Isolate QIA-B1201 had the ability to hemagglutinate red blood cells from several species of animals and was capable of adsorbing guinea pig erythrocytes on the surface of infected Vero cells. Nucleotide sequence analysis showed that two isolates (QIA-B1201 and QIA-B1204) had high similarity with other human and animal PIV5 isolates ranging from 98.1 to 99.8%. The highest sequence similarity of the two isolates corresponded to strain KNU-11 (99.8% at the nucleotide and amino acid level) isolated from suckling piglets in Korea in 2012. To evaluate the virulence of strain QIA-B1201, we inoculated bPIV5 into 5 week-old mice via both the intraperitoneal and intracranial route. Body weight was not significantly altered in mice inoculated with QIA-B1201. In this study, we isolated and characterized novel bPIV5s from brain samples showing downer cattle syndrome, but were not able to elucidate the pathogenicity of the bPIV5s in mice.

This study was conducted to investigate actual conditions associated with veterinary anesthetic drug use in Korea, and to obtain responses from Korean veterinarians and researchers pertaining to the use of anesthetic drugs. To accomplish this, a nationwide survey was issued to veterinarians working at animal hospitals and to researchers in the Korean Association for Laboratory Animal Science (KALAS). A self-administered questionnaire-based survey was then conducted in which respondents were asked questions about actual conditions associated with the use of animal anesthetic drugs. The survey revealed that the distribution and management of animal medicines in Korea was quite vulnerable to misuse or abuse due to a variety of factors. Therefore, a relevant regulatory system should be strictly enforced to protect vulnerable individuals from abuse or misuse.

Korean Journal of Veterinary Research.2014;54(2):91-99.

An antimicrobial susceptibility test was conducted to compare the resistance rates among Campylobacter spp. isolates from dogs (n = 50) raised under diverse conditions and humans (n = 50). More than 60% of Campylobacter (C.) jejuni from dogs and humans showed resistance to nalidixic acid, enrofloxacin and ciprofloxacin. C. jejuni isolates from humans showed higher resistance to tetracycline (83.3%) and ampicillin (91.3%) than those from dogs. None of the C. jejuni or Campylobacter coli isolates from humans or dogs were resistant to erythromycin. Overall, 85% of Campylobacter spp. isolates showed a multidrug resistant phenotype. Nucleotide sequencing analysis of the gryA gene showed that 100% of NA(R)/CIP(R) C. jejuni isolates from dogs and humans had the Thr-86th-Ile mutation, which is associated with fluoroquinolone resistance. flaA PCR restriction fragment length polymorphism (RFLP) typing to differentiate the isolates below the species level revealed 12 different clusters out of 73 strains. The human isolates belonged to eight different RFLP clusters, while five clusters contained dog and human isolates.

Korean Journal of Veterinary Research.2014;54(2):87-89.

In this study, the seroprevalence of Toxoplasma (T.) gondii and Bartonella (B.) henselae infection among stray cats in Daejeon City, Korea was surveyed. A total of seven samples were positive (7/118, 5.93%) for T. gondii including three samples from female cats (3/58, 5.2%) and four samples from male cats (4/60, 6.7%). There was no significant difference between the genders. A total 22 samples (22/118, 18.6%) were positive for B. henselae; nine were from females and 13 were from males. There was no significant difference between genders. Nineteen samples had a titer of 1 : 50, two samples had a titer of 1 : 100, and one sample had a titer of 1 : 200. The present study is the first to use serological tests to analyze B. henselae prevalence among stray cats in Korea.

In this study, trends in the sales of antimicrobials for use in livestock facilities and fisheries from 2003 to 2012 were investigated with regard to antimicrobial group, antimicrobial usage, and animal species. The overall amount of antimicrobials sold each year from 2003 to 2007 was 1,500 tons, after which they decreased, with the lowest sales being 936 tons in 2012. The total volume of antimicrobials used for feed additives decreased markedly by 94% from 2003 to 2012, which was mainly attributed to banning of feed additives. However, antimicrobial consumption through self prescription by farmers for disease prevention and treatment increased by 25% from 2003 to 2012. The largest volume of antimicrobials sold was for use in pigs (48~57%), followed by poultry (18~24%), fisheries (11~25%), and cattle (5~8%). Tetracycline was the highest selling antimicrobial, followed by penicillins and sulfonamides, although the overall sale of all three antimicrobials gradually decreased over the study period. This study demonstrated that the total consumption of antimicrobials has gradually decreased since 2008. Nevertheless, usage by nonprofessionals increased, which can ultimately cause emergence and spread of antimicrobial resistance. Thus, early establishment of veterinary prescription guidelines for prudent use of antimicrobials is urgently needed in Korea.
