| seroprevalence of toxoplasma gondii in dogs in shandong, henan, and heilongjiang provinces, and in the xinjiang uygur autonomous region, people's republic of china. | abstract seroprevalence of toxoplasma gondii infection was determined in sera of 632 (551 pets, 81 stray) dogs from shandong, henan, and heilongjiang provinces, and in the xinjiang uygur autonomous region, china (prc) using the indirect hemagglutination assay (iha, cut off titer 1:64 or higher); 11.1% were seropositive. the seroprevalence in stray dogs and in dogs ?3 yr-old was significantly higher (p < 0.05) than that in household dogs and in dogs <3 yr- old. there were no significant differe ... | 2011 | 21859330 |
| herd-level prevalence and associated risk factors for toxoplasma gondii, neospora caninum, chlamydia abortus and bovine viral diarrhoea virus in commercial dairy and beef cattle in eastern, northern and northeastern china. | although the seroprevalence of toxoplasma gondii, neospora caninum, chlamydia abortus and bovine viral diarrhea virus infection in cattle have been reported in some areas in china, most of them were conducted with small number of cattle samples and very limited districts and neglected the assessment of herd management factors associated with herd-level prevalence of these pathogen infections. thus, from september 2013 to december 2014, a large-scale seroprevalence study was conducted to determin ... | 2015 | 26231838 |
| seroprevalence of toxoplasma gondii in beef cattle and dairy cattle in northeast china. | the seroprevalence of toxoplasma gondii in beef cattle and dairy cattle in heilongjiang province, northeast china, was surveyed between april 2009 and may 2011. a total of 1803 (693 beef cattle and 1110 dairy cattle) serum samples were collected from 10 administrative regions rearing beef cattle and dairy cattle, and antibodies to t. gondii were examined by indirect hemagglutination (iha) test. the overall seroprevalence of t. gondii in beef cattle and dairy cattle was 2.6% (46/1803), and the pr ... | 2012 | 22545962 |
| seroprevalence of toxoplasma gondii infection in fattening pigs in northeast china. | seroprevalence of toxoplasma gondii infection in fattening pigs in heilongjiang province, northeast china, was investigated between july 2011 and june 2012. in total, 1,014 pig serum samples were collected from 10 administrative regions and assayed for t. gondii antibodies by indirect hemagglutination (iha) test using a commercially available kit. the average t. gondii antibody-positive prevalence was 4.6% (47/1,014), which is relatively lower than that in other provinces in china. seroprevalenc ... | 2013 | 23116060 |
| seroprevalence and risk factors of toxoplasma gondii infection in domestic sika deer (cervus nippon) in northeastern china. | toxoplasmosis is a worldwide zoonosis caused by toxoplasma gondii, which can infect warm-blooded animals and humans. a serological survey was undertaken to examine the seroprevalence and risk factors associated with t. gondii infection in sika deer in northeastern china. 114 (13.46%, 95% ci 11.16-15.76) out of 847 serum samples were positive to t. gondii by modiļ¬ed agglutination test (mat) at a 1:25 cut-off, with titers of 1:25 in 44, 1:50 in 32, 1:100 in 17, 1:500 in 11, 1:1500 or higher in 10. ... | 2014 | 25201489 |
| first report of toxoplasma gondii seroprevalence in farmed arctic foxes (vulpes lagopus) in eastern and northeastern china. | until now, no information on toxoplasma gondii seroprevalence in arctic foxes (vulpes lagopus) was available in china. a serological survey was undertaken to assess t. gondii seroprevalence in farmed arctic foxes in eastern and northeastern china. antibodies to t. gondii were examined in 1346 farmed arctic foxes using the modified agglutination test (mat). a total of 113 (8.39%, 95% confidence interval [ci] 6.91-9.87) serum samples were positive to t. gondii at a 1:25 cutoff. seroprevalence of t ... | 2015 | 26684525 |
| first genetic characterization of toxoplasma gondii infection in arctic foxes (vulpes lagopus) in china. | toxoplasma gondii can infect virtually all warm-blooded animals including foxes. however, little is known of the molecular epidemiology and genotypes of t. gondii infecting foxes in china. therefore, the present study characterized t. gondii genotypes in foxes in china for the first time. during november 2014 to october 2015, brain tissue samples collected from 264 arctic foxes (vulpes lagopus) in jilin, heilongjiang and shandong provinces were used to detect the t. gondii b1 gene by a semi-nest ... | 2016 | 27343765 |
