[Abstract]:Objective: To study the distribution, carrying and compound infection of new infectious pathogens in Mishan, Fenhe River, Jiayin, Dongning, Hualin, Tongjiang, Sunke, Lubei, Mudanjiang, Hei River, Raohe 11 port in Heilongjiang area. Method: From April, 2014 to October 2015, the ecological and biological history data of forest vegetation and medium-term disease in Heilongjiang port were integrated. Samples were collected by the cloth flag method. After morphological identification, the samples were numbered according to the area and type, and only one was detected. The method comprises the following steps of: carrying out independent subpackaging, numbering on the pipe wall, placing in a sterile steel ball, grinding the pellets into powder at a low temperature environment by using a grinder, storing at 4 DEG C, extracting tissue DNA according to the operation steps of the kit, establishing five new infectious diseases pathogens (Borrelia burgdorferi, carrying out specific fragment amplification on all samples by using a PCR or a nested PCR method, selecting a PCR positive fragment to carry out sequencing by using a PCR or a nested PCR method, The obtained sequences were compared with the online (NCBI) sequence, and analyzed by tree analysis to determine and analyze the geographic and characteristic distribution of pathogens in the media. Results: A total of 1306 samples were collected by classification and identification. Among the 1306 samples tested, there were only 25.42% of the total population, 25.42% of the whole trench, 23. 58% of the total channel, and 3. 14% of the Japanese blood. The result of the pathogen detection was in 1306 samples tested. A total of 1cases of Leishmania positive samples, 528 spotted fever group rickettsia positive samples, 11 cases of Bartonella positive samples, 31 cases of phagocyte-free positive samples, 11 cases of Lyme disease spiral positive samples were detected, and the infection rates were 0. 8%, 404. 3, 8. 4, 23. 7 and 8. 4%, respectively. A total of 8 pathogens were detected, including Borrelia afzelii, Borrelia garinii of Borrelia afzelii, Borrelia garinii, Babesia spp. of Borrelia garinii, Babesia spp., Racktsia raoulitii, New Taraswichtsia tabaci, Heilkettsia heilongjianguensis, Heilongjiang Province, respectively. Bartonella spp., phagocyte-free anaplasma phagocytophilum. The results of this study show that there are at least two Borrelia garinii, Borrelia afzelii, and three spot heat groups (Rickettsia raoulitii, Riceidi Rickettsia tarachaichensis, Rickettsia heilongjiangensis) in 11 port areas of Heilongjiang Province, and also confirms that the phagocyte-free body (Anapasma phagocytophilum), Babesia spp.), Bartonella spp.) The complex infection rate was 18. 4% (24/ 1306). Conclusion: There is a certain degree of compound infection in the media-borne diseases in Heilongjiang province. It is suggested that the risk of drug-borne diseases in Heilongjiang province is very high. It is urgent to strengthen the research on the monitoring and prevention and control of the infectious diseases and their complex infections in the area of Heilongjiang, and establish a scientific and reasonable system of early warning monitoring and prevention and control of disease-borne diseases.
