| seroprevalence of toxoplasma gondii in pigs from southern china. | the seroprevalence of toxoplasmosis in pigs was examined in china's southern guangdong province from march 2008 through may 2009. a total of 1,022 serum samples was collected from 12 administrative cities and assayed for toxoplasma gondii antibodies by enzyme-linked immunosorbent assay test. the seroprevalence ranged from 0 to 58.1% and the average t. gondii antibody-positive prevalence was 27.0% (276/1,022), with breeding boars having the highest level at 39.6% (38/96) followed by breeding sows ... | 2010 | 20557218 |
| seroprevalence of toxoplasma gondii in bred cynomolgus monkeys ( macaca fascicularis ) in china. | little is known of the seroprevalence of toxoplasma gondii in bred cynomolgus monkeys ( macaca fascicularis ) in china. in the present survey, 240 serum samples of cynomolgus monkeys from 4 nonhuman primate centers in guangxi zhuang nationality autonomous region (gx), and 120 serum samples from 2 nonhuman primate centers in guangdong province (gd) were obtained, and the modified agglutination test (mat) was performed to assay for anti- t. gondii antibodies. antibodies to t. gondii (mat titer of ... | 2010 | 20476808 |
| genetic characterization of toxoplasma gondii from pigs from different localities in china by pcr-rflp. | toxoplasma gondii is a widely prevalent protozoan parasite that causes serious toxoplasmosis in humans and animals. the present study aimed to determine the genetic diversity of t. gondii isolates from pigs in jiangxi, sichuan, guangdong provinces and chongqing municipality in china using multilocous polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) technology. | 2013 | 23919620 |
| molecular detection and genotypic characterization of toxoplasma gondii infection in bats in four provinces of china. | toxoplasma gondii is an intracellular protozoan parasite that infects a wide variety of warm-blooded hosts, including humans. limited information about t. gondii infection in bats is available in china. the objective of the present study was to determine prevalence and genetic characterization of t. gondii infection in bats in jilin, liaoning, jiangxi and guangdong provinces, china. | 2014 | 25465220 |
| seroprevalence of toxoplasma gondii infection in domestic pigeons (columba livia) in guangdong province of southern china. | little information on epidemiology of toxoplasma gondii infection in pigeons was available in people's republic of china. in the present study, sera from 275 pigeons raised in different commercial flocks in guangdong province of southern china were evaluated using modified agglutination test (mat). specific antibodies were found in sera of 8.7% of 275 pigeons (mat titer ≥ 1:5), and the seropositivity of eight herds we surveyed varied ranging from 0 to 18.2%. the results demonstrated the circulat ... | 2010 | 21208745 |
| seroprevalence of toxoplasma gondii in rats in southern china. | toxoplasma gondii is widely distributed in humans and other animals, including wild rats throughout the world, but little is known of the prevalence of t. gondii in rats in china. the seroprevalence of t. gondii in rats ( rattus norvegicus and rattus flavipectus ) was investigated in guangzhou, southern china, between november 2009 and january 2010. in total, 217 rat serum samples were collected; antibodies to t. gondii were detected by the modified agglutination test (mat), and 7 (3.2%) were fo ... | 2010 | 21158644 |
| isolation and characterization of toxoplasma gondii strains from stray cats revealed a single genotype in beijing, china. | cats are essential in the epidemiology of toxoplasma gondii because they are the only hosts that can excrete the environmentally resistant oocysts in nature. this study was aimed to determine the seropositivity, distribution of genotypes and mouse virulence of t. gondii from stray cats in beijing, china. a total of 64 serum samples, 23 feces and tissue samples were collected from stray cats in beijing. antibodies to t. gondii were assayed by the modified agglutination test (mat). 57.8% (37/64) o ... | 2012 | 22326429 |
| genotyping of toxoplasma gondii isolates from cats in different geographic regions of china. | fourteen isolates of toxoplamsa gondii were isolated from cats from 4 different geographic provinces (anhui, hubei, shanxi and guangdong) in china and their genetic diversity with 8 nuclear loci sag2, sag3, btub, gra6, l358, pk1, c22-8, c29-2, and an apicoplast locus apico, was analysed by restriction fragment length polymorphisms (rflps). two genotypes from these 14 isolates were identified but none of them belongs to the typical genetic types (types i, ii and iii). it is unexpected that such h ... | 2011 | 21757292 |
