| serological survey of canine dirofilariosis in chongqing, kunming, nanchang, fuzhou, guangzhou, shenzhen, and nanning in southern china. | the present study conducts a serological survey on the presence of canine dirofilariosis in domestic dogs using an enzyme-linked immunosorbent assay (elisa) kit. a total of 310 household dogs (166 females and 144 males) in chongqing, kunming, nanchang, fuzhou, guangzhou, shenzhen, and nanning in southern china were examined. of the 310 dogs, 42 (13.5%) were seropositive for dirofilariosis. no statistically significant difference was observed in terms of sex in the seroprevalence of dirofilariosi ... | 2011 | 22024016 |
| spotted fever group rickettsia in yunnan province, china. | abstract information about spotted fever group (sfg) rickettsiae in southern china remains sparse. a specific and sensitive real-time pcr assay for detection of sfg rickettsiae was established and used to detect the prevalence rate of sfg rickettsiae in yunnan province, china. the limit of detection (lod) of our real-time pcr was 200 copies per reaction, which is more sensitive than the previously developed nested pcr assays for rickettsia. we tested 265 blood samples (127 goats, 78 dogs, and ... | 2012 | 22225423 |

| predictors for presence and abundance of small mammals in households of villages endemic for commensal rodent plague in yunnan province, china. | ninety-one rodent plague epidemics have occurred in lianghe county, yunnan province, china, between 1990 and 2006. this study aimed to identify predictors for the presence and abundance of small mammals in households of villages endemic for rodent plague in lianghe county. | 2008 | 19068139 |
| serologic survey of the sentinel animals for plague surveillance and screening for complementary diagnostic markers to f1 antigen by protein microarray. | plague is a deadly infectious disease caused by the gram-negative bacterium, yersinia pestis. in 2005, five plague patients were confirmed in the yulong county of the yunnan province, china. in this study, the serologic survey of > 2,900 serum samples from domestic dogs and cats in and around the county, where human plague occurred, confirmed that domestic dogs and cats could serve as sentinel animals for plague surveillance. meanwhile, the antibody responses in the infected dogs and cats were p ... | 2008 | 18981526 |

| the epidemiology of human trichinellosis in china during 2000-2003. | the endemic foci of trichinellosis continue to be mainly located in the southwestern, the central and northeastern china. the seroepidemiological surveys of t. spiralis infection in humans were carried out in six provinces or municipals (p/m) of china during 2000-2003, the overall seroprevalence was 3.57%. from 2000 to 2003, 17 outbreaks of human trichinellosis, with 828 cases and 11 deaths, were recorded in 8 p/a of china. all of 11 deaths occurred in the southwestern china (1 case in sichuan, ... | 2006 | 16414006 |
