| [a investigation on the types of chromosomes and epidemiology of paragonimus westermanni in huadian city of jilin province]. | an investigation on the types of chromosomes and epidemiology of paragomanni westermanni in five villages and towns of huadian city was carried out. the data showed that the infection rate of crayfish, the first intermediate host, was 100% and the infectiosities varied from 99 to 160/per crayfish in the five areas. the genetic patterns of all the cysticercus, ovum and imagoes had been proved to be diploid by morphological and genetic studies. the infection rate of animal final host such as dogs ... | 1991 | 1811892 |
| toxoplasma gondii infection in pregnant women in china. | infection with toxoplasma gondii is common and usually asymptomatic, but it can have serious consequences in pregnant women if passed to the developing fetus. the aims of this study were to determine the prevalence of toxoplasmosis in pregnant women and to identify the possible risk factors associated with t. gondii infection in china. of a sample of 235 pregnant women in changchun, china, 25 (10.6%) were found by elisa to be positive for igg and none (0%) for igm. major risk factors were found ... | 2009 | 18822439 |
| sparse serological evidence of h5n1 avian influenza virus infections in domestic cats, northeastern china. | today the cross-species transmission of avian influenza viruses (aiv) are a great concern. a number of aiv strains are now enzootic among poultry, with h9n2 and highly pathogenic h5n1 aiv strains prevalent in china. h5n1 strains have been recognized to infect zoo and domestic feline species. in this serological study we sought to examine evidence that h5n1 strains have infected domestic cats in northeastern china. in 2013, we conducted a cross-sectional serological study of 916 healthy cats in h ... | 2015 | 25752867 |
| isolation and phylogenetic analysis of three feline calicivirus strains from domestic cats in jilin province, china. | feline calicivirus (fcv) is a highly prevalent pathogen that can cause infectious felid upper respiratory tract disease. the majority of complete genome sequences of fcv strains reported to date are from the usa. in this study, three fcv strains, ch-jl1, ch-jl2 and ch-jl3, were isolated from domestic cats in jilin province, china. sequence analysis revealed that except for strains hrb-ss, wz-1, xh, 12q087-1 and 12q087-5, the 3' untranslated regions (utrs) of ch-jl2 and ch-jl3 are more than 20 nu ... | 2017 | 28478577 |
