| pcr-sscp of rdna for the identification of trichinella isolates from mainland china. | a polymerase chain reaction (pcr)-based single strand conformation polymorphism (sscp) analysis of the expansion segment 5 (domain iv) of the large subunit of ribosomal dna was employed to characterize seven isolates of trichinella from china (a-g), including six of pig origin from regions in dengxian (a), tianjin (b), harbin (d), baoshan (e), xinye (f) and xian (g), and one of canine origin from changchun (c). isolates a, d, e, f and g were classified as trichinella spiralis based on sscp patte ... | 1998 | 9584075 |
| 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 |
| prevalence of helminthes in adult dogs in heilongjiang province, the people's republic of china. | the prevalence of helminthes in adult dogs was investigated in heilongjiang province, the people's republic of china, between 1996 and 2004. a total of 178 adult farm dogs from representative geographical locations in heilongjiang province were killed and examined for the presence of helminthes using a helminthological approach. the worms were examined, counted, and identified to species according to existing keys and descriptions. a total of 17 species of helminthes were found to infect dogs, a ... | 2006 | 16715234 |
| phylogenetic analysis of the haemagglutinin gene of canine distemper virus strains detected from breeding foxes, raccoon dogs and minks in china. | canine distemper virus (cdv) infects a variety of carnivores, including wild and domestic canidae. genetic/antigenic heterogeneity has been observed among the various cdv strains, notably in the haemagglutinin (h) gene, that appears as a good target to gather epidemiological information. based on sequence analysis of the h gene, wild-type cdv strains cluster into distinct geographic lineages (genotypes), irrespective of the species of isolation. the sequence of the h gene of 28 cdv strains detec ... | 2010 | 19647380 |
| Molecular identification of three Trichinella isolates from Heilongjiang Province, People's Republic of China. | DNAs of Trichinella dog isolate (HC), Trichinella swine isolate (HH) and Trichinella cat isolate (SW), obtained from Heilongjiang Province, were amplified by the fragments of 18S rDNA and ITS2. Two reference strains, Trichinella spiralis (ISS3) and Trichinella nativa (ISS10) were used for sequence comparison. Sequence and dendrogram analysis indicated that HC belonged to T. nativa and HH together with SW belonged to T. spiralis. This method permits rapid species identification of Trichinella iso ... | 2011 | 21864533 |
| 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 |
