Actin and some actin binding proteins such as tropomyosin, -actinin and troponin T were localized by simultaneous double immunogold labeling in several developmental stages of Cryptosporidium parvum. All of the observed developmental stages have many particles of tropomyosin and actin around pellicle and cytoplasm. Tropomyosin was labeled much more than the actin when these two proteins were labeled simultaneously. And alpha-actinin was labeled mostly in the pellicle, but troponin T labeling was very rarely observed. From this study, it was suggested that tropomyosin seems to be one of the major proteins of C. parvum, so it must be playing important roles in C. parvum.

DOI: https://doi.org/10.3347/kjp.1996.34.4.225
A survey of canine heartworm (Dirofilaria immitis) infections among German shepherds in five areas of South Korea was performed from October 1994 to August 1995 using a microfilarial test (modified Knott's test) and an antigen test (DiroCHEK , Synbiotics, USA). The infection rate of 127 German shepherds (71 males and 56 females) was 10.2% (13/127) by the microfilarial test, but was 28.3% (36/127) by the antigen test, revealing that 24 of the 36 antigen-positive dogs were microfilaria-negative in the peripheral blood. All dogs that were microfilaria-positive were also antigen-positive. Three of the microfilaria-negative and antigen-positive dogs contained 4 - 15 adult heartworms in the heart and pulmonary arteries upon necropsy. The infection rate among German shepherds was the highest in Hoengsong-gun (Kangwon-do, 84.4%), while those of Yechon-gun (Kyongsangbuk-do) and Chungwon-gun (Chungchongbuk-do) areas were 20.0% and 14.3%, respectively. None of the dogs in the Kimhae-shi (Kyongsangnam-do) and Kwangju areas was heartworm positive. The infection rates of heartworm in dogs at the age of 1-3, 4-6, and 7-11 years were 6.3%, 21.4%, and 56.4%, respectively. Based on the fact that the antigen test is more accurate than the microfilarial test, this study strongly indicates that the prevalence rate of canine heartworm in Korea may be higher than previously reported (3.1+=23.0%) which utilized microfilarial tests.

DOI: https://doi.org/10.3347/kjp.1996.34.4.233
The seroepidemiologic studies on anti-Toxoplasma antibody titers were carried out using ELISA and indirect latex agglutination test. Among 899 sera prepared from pregnant women, 39 cases (4.3%) revealed positive reaction and 218 sera from middle school students showed 4 positive reaction (1.8%) by ELISA. By LAT(newly established by National Veterinary Research Institute, Korea), the sera of 7 pregnant women (0.8%) showed positive reaction. When 80 sera showing +S1:8 by LAT were used for comparing the results obtained from LAT and Toxotest-MT (Eiken Chemical Co., Japan), 7 cases and 8 sera were positive, respectively. All of 11 sera of proven toxoplasmosis patients showed positive reaction in both tests. Overall proportion of agreement between LAT kit and Toxotest-MT was 0.94( -index= 0.632, p<0.01), and LAT was considered to be useful for the screening of toxoplasmosis.

Glutamate dehydrogenase antigen detection in Plasmodium falciparum infections
Dominiguez, Neira de , Rodriguez-Acosta, Alexis
Korean J Parasitol 1996;34(4):239-246.
DOI: https://doi.org/10.3347/kjp.1996.34.4.239
The usefulness of malaria diagnosis by Plasmodium falciparum-GDH (NADP+), obtained by affinity chromatography, is demonstrated in ELISA assays, testing IgG antibodies against GDH (NADP+) from patients with acute malaria, who have had two or more episodes of malaria, or from sera of hyperimmune patients. GDH (NADP+) thermal stability was demonstrated in a high heat resistance assay. The immunofluorescence assay demonstrated that anti-culture (P. falciparum) supernatant serum and anti-GDH (NADP+) of Proteus spp, recognized epitopes in Venezuelan isolates, and Colombian and Brasilian malarial strains. The antigen is soluble, with high specificity, is a potent immunogen and is thermoresistant.

Differentiation of invasive strains of Entamoeba histolytica according to their pathogenicity has been a topic of long debate, but now the pathogenic species only is regarded as E. histolytica while the non-pathogenic species is E. dispar. The present study applied immunoblot to differentiate infections of the two species among microscopically-detected cyst-passers in Korea. The crude extract of E. histolytica separated in 5-20% gradient gels, revealed many fractions of 94, 81, 71, 50, 44, 38.5, 37.5, 29, 19, and 18 kDa when the cysteine proteinase inhibitor, E64, was supplemented. The serum IgG antibody of proven E. histolytica cases reacted with the antigenic fractions of 117, 110, 99, 68, 66, 60, 54, 52, 46, and 45 kDa. Sera of PCR confirmed 3 cases of E. dispar reacted only to the 117 kDa fraction of the E. histolytica crude extract which was regarded as non-specific. To the antigen of monoxenic E. dispar, sera of E. dispar and E. histolytica cases showed the same immunoblot reactions. The serum IgA antibody reacted with several antigenic fractions of both E. histolytica and E. dispar, but IgM and IgE antibodies showed no reaction to either antigen. Sera of 24 symptomless amebic cyst-passers were screened with the E. histolytica antigen; two were found to be infected by E. histolytica and 22 were by E. dispar. The present findings suggest that in Korea most asymptomatic cyst passers of E. histolytica are carriers of E. dispar. Immunoblot using E. histolytica antigen is a good technique for the differentiation of E. histolytica and E. dispar infections.

Eight 2-day-old SPF chickens were each inoculated orally with a single dose of 5+O105 oocysts of Cryptosporidium baileyi, and immunoglobulin G (IgG) antibody responses were chronologically measured by indirect immunofluorescent antibody (IFA) assay. Anti-C. baileyi IgG antibody levels remained high(1:106.67 to 1:512.00) for at least 4 months with 330 days of a detectable period. Ten days after the negative conversion, each chicken was re-challenged with 1+O107 oocysts of the same species. Subsequent infection in 340-day-old individuals caused sudden elevated IgG antibody levels and the titer peaked on day 28 postchallenge inoculation(PCI), at 1:1,024 with a 65 days of detection period. Chickens in primary infection showed oocyst shedding profiles, but did not exhibit any oocyst shedding before or after experimental reinfection.

The taxonomic validity of morphological group III Acanthamoeba spp. is uncertain. In the present study, six type strains of group III Acanthamoeba spp., Acanthamoeba culbertsoni, A. healyi, A. pustulosa, A. palestinensis, A. royreba and A. lenticulata were subjected for the evaluation of their taxonomic validity by comparison of the isoenzyme patterns by isoelectic focusing on polyacrylamide gels, mitochondrial DNA (Mt DNA) restriction fragment length polymorphism (RFLP), and small subunit ribosomal DNA (ssu rDNA) PCR-RFLP patterns. The Mt DNA RFLP patterns were heterogeneous between species. The type strains of A. palestinensis and A. pustulosa showed almost identical patterns of isoenzymes and rDNA PCR-RFLP with an estimated sequence divergence of 2.6%. The other species showed heterogeneous patterns of isoenzymes and rDNA PCR-RFLP. It is likely that A. pustulosa is closely related with A. palestinensis and that the former may be regarded as a junior synonym of the latter.

Case Report

A clinical case of Cheyletiella infestation on a dog born and raised in Korea is reported. A three-year old female Whippet was hospitalized due to a multiple fracture and displacement of the left scapula caused by a recent car accident. The mite infestation was not noticed at the time of hospitalization. The dog underwent multiple operations involving internal fixation of the fractured scapula with wire and a plate, followed by extensive chemotherapy with antibiotics and prednisolone. After two months of hospitalization, a pruritic dermatitis near the left scapula developed. Multiple white dandruff-like flakes were seen on the hair coat, especially over the dorsal spine and neck, and the dog expressed increased pruritus by frequently licking and scratching the affected areas. Local dense accumulations of skin debris that became crusty were also observed. Microscopic examination of a skin scraping revealed a heavy infestation of Cheyletiella yasguri, as identified by the presence of hooks of the palpi and the heart-shaped sensory organ on genu I. Immunosuppression elicited by the extensive administration of prednisolone was suspected for the initiation of the generalized mite infestation.

Original Articles
An epidemiologic survey along the several sites of southern coastal areas of Korean peninsula was performed to know the infection status of Parvatrema spp. metacercariae in Tapes philippinarum. The clams were purchased from 13 coastal areas in Kyongsangnam-do and Chollanam-do, in September, 1990. Each of them was digested with pepsin-HCl solution and examined under a stereomicroscope for the recovery of metacercariae. A total of 232 (77.3%) out of 300 examined clams were proved to have 1 to 273 Parvatrema spp. metacercariae (54.7 in average). None of the clams from Samsan-myon Kosong-gun and Dolsan-up, Yochon-gun was infected with metacercariae. However, all of the clams from Yonghyun-myon, Sachon-gun, Dohwa-myon, Kohung-gun, Ahllyang-myon, Changhung-gun and Chiryang-myon, Kangjin-gun was infected with about 71, 31, 80 and 42 metacercariae respectively. Of the clams from Kohyun-myon, Namhae-gun, Doam-myon, Kangjin-gun and Kusan-myon, Uichang-gun examined, 97.5%, 95.0% and 90.0% were infected with about 117, 76 and 28 metacercariae. In other 4 surveyed areas, Seolchon-myon, Namhae-gun, Hwayang-myon, Yochon-gun, Byollyang-myon, Sungju-gun and Bukpyung-myon, Haenam-gun, 55.0%-80.0% of clams were positive, and their average intensity of infection ranged from 6 to 25 metacercariae. From these results, it was confirmed that Tapes philippinarum from southern coastal areas of Korea are highly infected with Parvatrema spp. metacercariae.

The enzyme linked immunosorbent assay (ELISA)-inhibition test using a Clonorchis sinensis species-specific mouse monoclonal antibody(MAb), CsHyb 0605-23, showed increased specificity over the conventional ELISA used for serodiagnosis of clonorchiasis. To characterize the corresponding antigen further, the MAb was tested against polysaccharide, protein and glycolipid fractions obtained from a crude extract of C. sinensis adult worms, using chloroform, methanol and phenol extractions. Only the polysaccharide fraction was recognized by the MAb among those fractions. Mild oxidation of the antigen with sodium periodate showed decreased reactivity against the MAb. We concluded that the antigen and antigenic determinants recognized by the MAb are carbohydrates.

Six metacercariae were found from the gill filaments of Conger myriaster purchased at Mokpo City in Korea on 7 September 1996. Based on the morphology of the excysted specimen, we identified them as metacercariae of Heterophyopsis continua. C. myriaster is a new intermediate host of H. continua in the literature.
