■本研究旨在分析媒介蜱和水库宿主啮齿动物的种群密度,并调查浙江省相关病原体感染情况,中国。
■在这项监测研究中,通过动物体表蜱采摘法和拖标法收集蜱密度数据,而啮齿动物密度用夜间诱捕法。检查蜱的样本是否有严重的发热伴血小板减少综合征病毒(SFTSV),对啮齿动物的血清和器官进行SFTSV,汉坦病毒,钩端螺旋体,虫虫东方(O.tum虫)和鼠疫耶尔森氏菌(Y.鼠疫杆菌)在实验室进行筛查。
■2017年至2022年浙江省,在1848只阳性动物中发现了16230只寄生蜱,寄生蜱的密度为每只寄主动物1.29只,并从1,140,910米的植被距离中捕获了总共5,201个探查蜱,探查蜱密度为0.46蜱/flag·100m。长鱼眼(H.longicornis)是主要物种。共发放捕鼠器2,187,739只,诱捕啮齿动物12,705只,密度为每100个陷阱之夜0.58个。褐家鼠是主要物种。对于SFTSV筛选,两组长柄H.longicornis的若虫蜱被检测为阳性。对于啮齿动物样本,钩端螺旋体阳性率为12.28%(197/1604),汉坦病毒为1.00%(16/1604),和O.tsu虫为0.15%(2/1332)。在啮齿动物样品中,SFTSV和鼠疫耶尔森氏菌均未发现阳性结果。
■研究结果表明,蜱和啮齿动物在浙江省分布广泛。特别是,SFTSV的阳性检测,钩端螺旋体,汉坦病毒和O。来自该地区的蜱虫或啮齿动物中的tu虫建议应更加注意相关媒介传播疾病发生的可能性。
UNASSIGNED: This
study aimed to analyze the population density of vector ticks and reservoir hosts rodents, and to investigate the relevant pathogen infection in Zhejiang Province, China.
UNASSIGNED: In this surveillance
study, the data of ticks density were collected with the tick picking method on animal body surface and the drag-flag method, while the rodent density with the night trapping method. The samples of ticks were examined for the severe fever with thrombocytopenia syndrome virus (SFTSV), and blood serum and organs from rodents were subjected for SFTSV, hantavirus, Leptospira, Orientia tsutsugamushi (O. tsutsugamushi) and Yersinia pestis (Y. pestis) screening in the laboratory.
UNASSIGNED: From 2017 to 2022 in Zhejiang Province, 16,230 parasitic ticks were found in 1848 positive animals, with the density of parasitic ticks of 1.29 ticks per host animal, and a total of 5,201 questing ticks were captured from 1,140,910 meters of vegetation distance with the questing tick density of 0.46 ticks/flag·100 m. Haemaphysalis longicornis (H. longicornis) was the major species. A total of 2,187,739 mousetraps were distributed and 12,705 rodents were trapped, with the density of 0.58 per 100 trap-nights. Rattus norvegicus was the major species. For SFTSV screening, two groups nymphal ticks of H. longicornis were tested to be positive. For the rodents samples, the Leptospira had a positive rate of 12.28% (197/1604), the hantavirus was 1.00% (16/1604), and the O. tsutsugamushi was 0.15% (2/1332). No positive results were found with SFTSV and Y. pestis in the rodents samples.
UNASSIGNED: Findings from this
study indicated that the ticks and rodents were widely distributed in Zhejiang Province. Particularly, the positive detection of SFTSV, Leptospira, hantavirus and O. tsutsugamushi in ticks or rodents from this area suggested that more attention should be paid to the possibilities of relevant vector-borne diseases occurrence.
