Abstract:
To understand the sero-epidemiological features of rickettesiosis of humans and domestic animals in Yunnan province, blood samples from 237 adults in different geographic area, including Xundian country,Yulong country and Simao country and 81 children aged from 4 to 6 years old were collected for serological testing. In addition, 90 blood samples from dogs, goats and ox in each investigated area were also collected. Antibodies against 8 rickettsiae, including R.typhi, R.heilongjiangii or R.sibirica, Orientia tsutsugamushi Karp or Kato, Ehrlichia chaffeensis, Anaplasma phagocytosis, Bartonella henselae, Coxiella burnetii and Hainan spotted fever group of rickettsia were examined by using immunofluorescence assays(IFA).It was found that the sero-epidemiologic rates of R.typhi, B.henselae and C.burnetii (16.46%、6.33% and 9.28%) of adults were higher than those of other rickerrsiae investigated. The positive rates of IgG antibody against R.typhi for children also shared the higher rate (12.35%). Similar sero-epidemiologic features were found for domestic animals. Among the 8 rickettsia tested in this study, the positive rate of IgG antibody against R.typhi appeared to be the highest(61.48%) without significant difference among these investigated sites. From this investigation, it is evident that the rickettsial infection of farm population and domestic animals are common in Yunnan province, and the active surveillance of rickettsiosis and differential diagnosis of unknown febrile patients in clinical practice should be enforced.
