| mosquitoes and mosquito-borne arboviruses in the qinghai-tibet plateau--focused on the qinghai area, china. | an investigation was conducted to identify the distribution of mosquitoes and mosquito-borne arboviruses in the qinghai-tibet plateau, china from july to august in 2007. a total of 8,147 mosquitoes representing six species from three genera (aedes, culex, and anopheles) were collected in three locations (geermu city, altitude of 2,780 m; xining city, 2,200 m; minhe county, 1,700 m). six virus isolates were obtained including tahyna virus (tahv), liaoning virus, and culex pipiens pallens densovir ... | 2010 | 20348523 |
| Seroprevalence of Toxoplasma gondii infection in slaughtered pigs and cattle in Liaoning Province, northeastern China. | Abstract Toxoplasmosis is an important food-borne parasitic disease. In this study, the seroprevalence of Toxoplasma gondii infection in slaughtered pigs and cattle was surveyed in Liaoning Province, northeastern China in May and June 2011. In total, 1,164 porcine serum samples and 646 bovine serum samples were collected from 5 counties and examined for T. gondii antibodies by an indirect haemagglutination (IHA) test. Antibodies to T. gondii were found in 12.0% (140/1,164) of pigs with some re ... | 2011 | 22032402 |
| characterization of the ghr gene genetic variation in chinese indigenous goat breeds. | the aim of the present work was to investigate single nucleotide polymorphism (snp) of growth hormone receptor (ghr) gene exon 10, characterize the genetic variation in three chinese indigenous goat breeds, and search for its potential association with cashmere traits. in this study, a polymerase chain reaction-single strand conformation polymorphism (pcr-sscp) protocol has been developed for rapid genotyping of the ghr gene in goats. one hundred seventy-eight goats from liaoning cashmere (96), ... | 2011 | 20364329 |
| seroepidemiology and genetic characterization of hepatitis e virus in the northeast of china. | the aim of this study was to analyze the prevalence of infection and genotype of hepatitis e virus (hev) in people and animals in the northeast of china (heilongjiang, jilin and liaoning provinces). this seroepidemiological study was conducted using enzyme immunoassays and human sera positive for hev antigen or anti-hev igm, and animal sera positive for hev antigen or with an s/co <or=10 for anti-hev were tested for hev rna using real-time rt-pcr and nested rt-pcr. in humans, the overall prevale ... | 2009 | 19460321 |
| [an epidemiologic analysis of brucellosis in liaoning province]. | in order to understand the increasing incidence rate of brucellosis, the relationship between the epidemic trend and physical conditions of humans, data regarding brucellosis in liaoning province, in 1990-1996 was analysed. results showed that the major cause which led to the brucellosis recurrence was the importation of sheep named short-tail cold-resistant. the distribution of disease was widely spread. however, most endemic foci were being expanded. the spots in tieling and fushun area were m ... | 1998 | 10322712 |
