| restriction fragment length polymorphism (rflp) analysis of genomic dna of 5 strains of trichinella spiralis in china. | five restriction endonucleases were used to digest genomic dna from 5 isolates of trichinella spiralis obtained from changchun, tianjin, xian, henan and yunnan. all the isolates were secured from pigs except the changchun strain which came from dog. the dna fragments digested by endonuclease were separated by agarose gel electrophoresis. the changchun isolate had a ecori band at 1.12kb and a drai band at 1.97kb which were unique to this isolate. a cloned specific repetitive dna sequence (1.12kb) ... | 1995 | 8580480 |

| epidemiological survey of trichinella infection in some areas of henan province. | during 1996-1998 epidemiological survey of domestic trichinella spiralis infection and serological survey on human beings were carried out in yanling, xuchang counties and luohe city. by the artificial digestion method, the positive rates of pork in market and mutton were 1.6% and 0.6% respectively. meat samples of pigs from pig-farms, cats and dogs were all negative for trichinella larvae. trichinellosis infection levels in rats captured in peasant households and places around abattoirs were 0. ... | 2001 | 11484388 |
| outbreaks of human trichinellosis caused by consumption of dog meat in china. | dog meat has become an important source of trichinella infection for humans in china. the first documented outbreak of human trichinellosis resulting from the consumption of dog meat occurred in china in 1974. until 1999, the outbreaks with this source of infection occurred mostly in northeast of china (81 cases in five outbreaks in jilin and two in liaoning), beijing (six cases) and henan provinces (two cases). the epidemiological surveys were performed in nine provinces or autonomous regions o ... | 2001 | 11484389 |
