| characteristics of different isolates of schistosoma japonicum from china in the final hosts. | the present paper deals with the susceptibility of common laboratory animals, such as mouse, rat, hamster, jird, rabbit and rhesus monkey, to infection with different isolates of schistosoma japonicum in the mainland of china under laboratory conditions. with the exception of the rat, all the animals under study were permissive hosts for different isolates though their worm recovery rates varied. the mean body length of pair-worms of the yunnan isolate was considerably smaller than that of the a ... | 1991 | 1948285 |
| [studies on the strain differences of schistosoma japonicum in the mainland of china. iv. fuzzy cluster analysis on some biological characters of different isolates of schistosoma japonicum]. | in this paper, a computerized numerical systematics was used to analyse the 5 different isolates of schistosoma japonicum in the mainland of china by means of fuzzy clustering method with 32 quantitative data of each isolate about the morphological and biological characters. a dendrogram of the 5 isolates of s. japonicum was constructed on the basis of similarity coefficients as shown. the phylogenetic relationships revealed by the present study show that the two isolates of anhui and hubei get ... | 1991 | 1959166 |
| [studies on the strain differences of schistosoma japonicum in the mainland of china. iii. morphometric data]. | the present investigation was undertaken to determine whether differences exist in the size of cercariae, adult worms and eggs among different isolates of s. japonicum in the mainland of china. measurements on the corresponding stages of japanese and philippine strains of s. japonicum were also carried out for comparison. the size of cercariae collected from pooled naturally infected snails from different isolates was shown in table 1. the body index of yunnan isolate, which is defined as cercar ... | 1991 | 2065446 |
| [studies on the strain differences of schistosoma japonicum in the mainland of china. ii. susceptibility of mammalian hosts]. | six species of animals were percutaneously exposed to cercariae obtained from pools of naturally infected snails from different isolates of s. japonicum in the mainland of china as shown in tables 1 and 2. our results indicated that with the exception of rat, all animals under study were permissive host though their worm recovery rates varied with different isolates. the mean prepatent period in different host species were 35.0 +/- 0.8 to 36.4 +/- 1.0 days for anhui isolate; 34.5 +/- 1.2 to 36.4 ... | 1990 | 2099256 |
| antigenic characterization and elisa detection of adult diarrhea rotaviruses. | recently, severe epidemics of diarrhea among both adults and children in china have been associated with an agent called adult diarrhea rotavirus (adrv). we have studied adrv from two areas of china (jinzhou and guangxi) and compared them with prototype group a, b, and c rotaviruses. the viral genomes were compared by electrophoresis of the rna genome segments in polyacrylamide gels, and the antigenic relatedness of these viruses was examined by immune electron microscopic studies using virus pr ... | 1986 | 3016112 |
| sds-page protein pattern and its antigenicity analysis of different isolates of schistosoma japonicum in china. | homogenates prepared from s. japonicum adult worms of different isolates from anhui, hubei, guangxi, yunnan and sichuan provinces were analyzed by sds-page and enzyme linked immunoelectrotransfer blot (eitb) tested with rabbit anti-snails antibody. the results of sds-page indicated that with silver staining both male and female worms of guangxi isolate showed some definite differences in their protein profile, namely, absence of one band between 50-75 kda in male worms and marked reduction in qu ... | 1994 | 8187569 |
| p53 protein expression in patients with hepatocellular carcinoma from the high incidence area of guangxi, southern china. | mutation of the p53 gene has been reported in hepatocellular carcinoma (hcc) occurring worldwide. the most frequent p53 mutation has been found in hccs in regions with high hepatitis b virus (hbv) infection and intake of aflatoxin b1 (afb1). the aim of our study was to examine p53 protein expression in hccs from a high incidence area of guangxi, southern china, where hbv infection and dietary intake of afb1 are high. immunohistochemical staining of p53 protein was carried out using a polyclonal ... | 1997 | 9570360 |
| geographical variation of the liver fluke, clonorchis sinensis, from korea and china based on the karyotypes, zymodeme and dna sequences. | genetic characterization was carried out in order to reveal the geographical variations of the oriental liver fluke, clonorchis sinensis (trematoda: opisthorchiidae), collected in korea and china. the chromosome number was 2n=56 in both korean (kimhae) and chinese (liaoning) flukes, and chromosomes were divided into two groups based on their sizes; consisting of 8 pairs of large and 20 pairs of small chromosomes. however, the karyotypes showed some differences between korean and chinese flukes. ... | 2001 | 12041573 |

| [sequencing of mitochondrial dna cytochrome oxidase subunit i gene in sarcosaphagous flies from 14 provinces in china]. | to detect the 278 bp region of gene of the cytochrome oxidase subunit i (coi) in mitochondral dna (mtdna) of sarcosaphagous flies, identify the species of sarcosaphagous flies, and provide reference for forensic application. | 2010 | 20818074 |
| [studies on the strain differences of schistosoma japonicum in the mainland of china. xi. enzyme linked immunoelectrotransfer blot analysis]. | antigens prepared from s. japonicum adult worms of different isolates i. e. anhui, hubei, guangxi, yunnan and sichuan by origin were analyzed by enzyme linked immunoelectrotransfer blot (eitb) probed with rabbit anti-snail antibody (figs 1,2). anti-sera against oncomelania h. hupensis from anhui, hubei, yunnan and sichuan localities were prepared separately and used in the tests. the eitb patterns were similar in s. j. isolates of anhui and hubei, and it was also the case among s. j. isolates of ... | 1992 | 1303328 |
| Serotype and genotype diversity of infectious bronchitis viruses isolated during 1985-2008 in Guangxi, China. | The genetic diversity of the hypervariable region I of S1 gene (HVR I) of infectious bronchitis (IB) vaccine strains H120, Ma5 and 4/91 was compared to that of 26 infectious bronchitis virus (IBV) strains isolated from the field in Guangxi province of China during the years 1985-2008, and the field isolates were classified into five major genotypes. Monovalent antisera against three vaccine strains and seven field isolates of different genotypes were prepared by immunizing rabbits with mineral o ... | 2011 | 22198411 |
