目的了解顺德港客运口岸鼠类种群分布、季节消长情况及其自然感染病原体情况,为制定有效灭鼠措施和建立鼠类地理分布和信息预警系统提供科学依据。方法采用笼捕法和粘鼠板法,于2014年5月—2015年4月连续调查和监测鼠密度,并对调查资料进行统计分析。结果共捕获鼠形动物38只,经分类鉴定隶属2目2科2属2种,以褐家鼠为优势种,占鼠类种群构成的55.26%,其次为臭鼩鼱,占44.74%。本底调查和监测以垃圾存放点的鼠捕获率为最高,分别为44%和59%。本底调查平均鼠密度为0.18%,监测平均鼠密度为0.41%,鼠密度高峰出现在5月。病原体检出阳性数为4,阳性率为7.55%,且餐饮单位生境的病原体检出率最高,为22.22%。结论应采取预防为主、综合治理的方法加强对口岸鼠类栖息繁殖地区的专项治理,降低鼠密度,防止病媒传染病发生和蔓延。
Objective To understand the distribution of rodent population, seasonal fluctuation and pathogens in Shunde Port, and to provide a scientific basis for the development of effective anti-rat measures and establishment of geographic distribution and early warning system of rodents. Methods The cage density and sticky rat plate method were used to investigate and monitor the rat density continuously from May 2014 to April 2015 and statistical analysis of the survey data was carried out. Results A total of 38 mouse-shaped animals were captured. Two species belonging to 2 orders, 2 families and 2 genera were identified. Rattus norvegicus was the dominant species, accounting for 55.26% of the total, accounting for 44.74% of the total. The background capture and monitoring of rat trapping sites at the highest rate of capture, respectively, 44% and 59%. The average background density was 0.18%, the average monitoring density was 0.41%, and the rat density peak appeared in May. The positive number of pathogens was 4, the positive rate was 7.55%, and the highest detection rate of pathogens in catering habitat was 22.22%. Conclusion Prevention should be taken as the main method and comprehensive treatment should be taken to strengthen the special treatment in the habitat and reproduction areas of port mice, reduce the density of the rats and prevent the occurrence and spread of vector-borne diseases.
