| [antimicrobial susceptibility and related genes of salmonella serovars from retail food in shaanxi province]. | salmonella isolates from retail food were examined for antimicrobial susceptibility and further characterized to better understand the development and dissemination of antimicrobial resistance among foodborne salmonella in china. | 2010 | 20687345 |
| genotyping cryptosporidium andersoni in cattle in shaanxi province, northwestern china. | the present study examined the prevalence and genotypes of cryptosporidium andersoni in cattle in shaanxi province, china. a total of 2071 fecal samples (847 from qinchuan cattle and 1224 from dairy cattle) were examined for the presence of cryptosporidium oocysts, and 70 samples (3.4%) were c. andersoni-positive and those positive samples were identified by pcr amplification of the small subunit ribosomal rna (ssu rrna) and the cryptosporidium oocyst wall protein (cowp) genes. c. andersoni was ... | 2013 | 23560072 |
| Lack of an association between a single nucleotide polymorphism in the bovine myogenic determination 1 (MyoD1) gene and meat quality traits in indigenous Chinese cattle breeds. | The myogenic determination 1 (MyoD1) gene is a member of the MyoD gene family. It encodes for skeletal muscle-specific transcription factors containing highly conserved basic helix-loop-helix regions that perform important roles in the initiation, maintenance, and regulation of phenotypic traits. We investigated a new single nucleotide polymorphism (SNP) in the MyoD1 gene to evaluate whether this polymorphism affects meat quality traits in five Chinese indigenous cattle breeds, namely Qin ... | 2011 | 21968728 |
| population genetic analysis of 6 y-str loci in chinese northwestern qinchuan yellow cattle breed. | six y-str loci (umn0929, umn0108, umn0920, inra124, umn2404 and umn0103) were analyzed using 576 healthy and unrelated males and 10 females of the qinchuan cattle population in chinese shaanxi province. allele frequency, gene diversity, the polymorphic information content, and the number of effective gene were calculated. all loci were in accordance with the hardy-weinberg equilibrium (p > 0.05). the population data were compared with published data of other cattle breeds, suggesting that qinchu ... | 2010 | 19823952 |
| serologic association between human papillomavirus type 16 infection and esophageal cancer in shaanxi province, china. | the existence of large geographic variations in the prevalence of esophageal cancer in some countries, such as china, indicates that environmental risk factors may be important in the development of this disease. some studies have implicated genital-mucosal strains of human papillomaviruses (hpvs) in the etiology of this cancer. | 1996 | 8841021 |
| prevalence and characterization of salmonella serovars in retail meats of marketplace in shaanxi, china. | a total of 764 retail meat including 515 chicken, 91 pork, 78 beef and 80 lamb samples were collected in shaanxi province of china in 2007-2008 to determine the prevalence of salmonella. the isolates were characterized using serotyping, antimicrobial susceptibility testing, and the presence of bla(cmy-2) and bla(tem) and class i integrons. selective serovars were further subtyped using pfge. approximately 54% (276) of chicken, 31% (28) of pork, 17% (13) of beef and 20% (16) of lamb samples were ... | 2010 | 20493570 |
