We described a rapid, sensitive and reproducible real-time PCR assay for detection and quantitation of canine parvovirus type 2 in the feces of dogs with parvovirus infection. The method was demonstrated to be highly specific and sensitive, allowing a precise canine parvovirus type-2 quantitation over range of eight orders of magnitude from $10^2\;to\;10^9$ copies of standard DNA. Then, fecal samples from parvovirus infected dogs were analyzed by conventional PCR and real-time PCR. Real-time PCR is more sensitive than conventional PCR, allowing to detect low viral titers of CPV-2 in infected dogs. By real-time PCR, a wide range of parvovirus particles was found in the samples from $1.45\times10^6\;to\;9.45\times10^8$ copies/0.01g of feces. However, when dogs are in infection of parvovirus, it is difficult to prove that the numbers of peripheral blood leukocytes are correlated with those of fecal shedding virus.

The results from a total of 412 blood samples consisted of 187 samples from regular visiting group (RV), 94 samples from first visiting group (FV), 52 samples from abandoned group (A), 54 samples from special breeder group (SB), and 25 samples from preliminary breeder group (PB) showed that RV(94.7%) and SB(88.9%) groups had the higher levels of protective antibody, but PB (36.0%) group revealed the lowest level. Among 96 blood samples with lower protective antibody levels, 14 samples (14.6%), 72 samples (75.0%) and 10 samples (10.4%) were below the protective antibody levels to distemper/parvo-virus, distemper only and parvovirus only, respectively. These results implied that antibody to parvovirus was well generated than that to distemper. Eighty six samples (20.9%) showed the protective antibody titer under 1:96 to distemper and 24 samples (5.8%), the protective antibody titer under 1:40 to parvovirus.

To study the immunomodulatory effect of aquapuncture with canine parvovirus killed vaccine, the vaccine was inoculated into the dogs twice with on 2-week interval. The 6 dogs in the experimental group were inoculated through the Jiao-Chao acupoint, and 5 dogs in the control group were done subcutaneously. The antibody titer was determined by the hemagglutination inhibition test. The HI titers of the experimental group showed significantly higher on days 21 and 28 than those of the control group. The biochemical test on serum total protein, protein fractions and the A/G ration showed a slightly increased in $\gamma$-globulin on days 21 and 28. The hematological findings on total leukocytes and differential counts showed no significance. It was thought that the aquapuncture of the canine parvovirus killed vaccine through the Jiao-Cho acupoint may stimulate the antibody production.

This study was performed to verify the effect of modified live virus vaccine against canine parvovirus (CPV) infection. Serum hemagglutination inhibition (Hl) test, histopathological and immunohistochemical techniques and polymerase chain reaction were used. The results were as follows: 1. During the experimental terms after vaccination, serum Hl titer was stable. Geometric mean titer (GMT) after the 1st vaccination was 280. After virulent CPV was challenged, GMT was 1,306. 2. After challenge by virulent CPV, the vaccinated group was not shown clinical signs and gross and histopathological findings. 3. After challenge by virulent CPV, the vaccinated group was not detected viral antigens in the small intestine immunohistochemically. 4. After challenge by violent CPV, the vaccinated group was not shown virus shedding in feces. In conclusions the overall results confirmed that modified live virus vaccine was effective on prevention of canine parvovirus infection.

Rituximab (RTX), a monoclonal antibody against the B-cell marker CD20, is commonly used as a treatment for antibody-mediated diseases or B-lymphocyte-mediated diseases. Destruction of B cells may reverse the disease course in many conditions; however, patients who are treated with RTX cannot respond appropriately to de novo infection due to lack of B lymphocytes. Here, we report one such case. A 7-year-old renal allograft recipient presented with severe anemia due to parvovirus infection after RTX treatment. The patient had focal segmental glomerulosclerosis and had received cadaveric kidney transplantation 6 months previously. She was treated with high-dose steroid for acute rejection and RTX for Epstein Barr Virus infection 3 months previously. At presentation, her hemoglobin level was 5.4 g/dL and leukocyte and platelet counts were normal. She had microcytic normochromic anemia and high viral load of parvovirus B19(70,578 copies/mL). Intravenous immunoglobulin ($200mg/kg{\cdot}d$) treatment controlled the progression of anemia and parvovirus infection. De novo parvovirus infection during the B lymphocyte-depletion period may have precipitated the severe anemia in this case. Close monitoring of infection is required after RTX therapy.

목적: 인간 파르보바이러스 B19 감염은 무증상에서 생명을 위협하는 합병증에 이르기까지 광범위하고 다양한 증상을 나타낸다. 우리는 파르보바이러스 B19 감염의 지역사회 내 집단발생 시기 동안, 파르보바이러스 B19 감염의 다양한 임상 양상에 대해 조사하였다. 방법: 2017년 12월부터 2019년 4월까지 부산대학교 어린이병원에서 파르보바이러스 B19 면역 글로불린 M (IgM) 또는 중합효소 연쇄 반응(polymerase chain reaction, PCR)에 의해 검출된 파르보바이러스 B19 DNA를 가진 소아의 임상적 특징을 후향적 차트 분석을 통해 알아보았다. 결과: 24명의 어린이가 파르보바이러스 B19 감염으로 진단되었다. 24명의 환자 중 12명(50%)은 레이스 형태 발진이 있었고, 24명의 환자 중 4명(16.7%)은 점상출혈 발진, 24명의 환자 중 2명(8.3%)은 무병소 발열로 진단되었다. 24명 중 6명의 환자(25%)는 골수무형성위기가 발생하였고, 이 중 3명은 이전에 유전 구형적혈구증, 3명은 이전에 급성 림프모구 백혈병으로 진단되었던 환자이다. 결론: 감염홍반 외에도 파르보바이러스 B19 감염의 임상적 특징은 다양한 종류의 발진과 무병소 발열으로 나타날 수 있다. 또한, 혈액학적 증상으로 중성구 감소증, 골수무형성 위기와 같이 발생할 수 있다.
