Abstract

Subject

Rickettsia is a zoonotic bacterial pathogen transmitted by vectors and has extensive reservoirs in animal and human populations. Rickettsiosis is a public health problem all over the world. However, comprehensive information on the geographical distribution of different Rickettsia species, infection status of reservoirs, vectors, and human cases is lacking in most parts of the world. Therefore, this study aimed to investigate the geographical distribution of different Rickettsia species and their vectors in countries of the WHO-EMRO region.

Methods

In this review study, a search was conducted for reports and published studies on Rickettsia species from WHO-EMRO region countries in various databases from 1995 to 2022. Finally, the reported status of human cases, reservoirs, and vectors associated with each species in different countries was documented.

Results

Reports of infections related to the detection of Rickettsia species were only available for 15 out of 22 WHO-EMRO member countries. A total of twenty-four Rickettsia species, including R. sibrica, R. lusitaniae, R. africae, R. prowazekii, R. felis, R. typhi, R. rickettsii, R. aeschlimannii, R. conorii, R. massiliae, R. helvetica, R. monacensis, R. rhipicephali, R. bellii, R. asembonensis, R. hoogstraalii, R. andeanae, R. raoultii, R. asiatica, R. slovaca, R. australis, R. barbariae, Candidatus R. amblyommii, and Candidatus R. goldwasserii, were reported from WHO-EMRO member countries. Furthermore, human cases infected with six different Rickettsia species, including R. sibrica, R. prowazekii, R. felis, R. typhi, R. rickettsii, R. aeschlimannii, R. conorii, R. massiliae, and R. helvetica, were reported from these countries.

Conclusion

The vast diversity of Rickettsia vectors has contributed to the ongoing discovery of new Rickettsia species. Therefore, further research on the reservoir hosts of Rickettsia infections in the understudied WHO-EMRO region is crucial. This research sheds light on Rickettsia disease's epidemiology and transmission dynamics in this region.

世界卫生组织东地中海（WHO-EMRO）地区各国不同立克次体的分布情况：概述。

主题立克次体是一种通过病媒传播的人畜共患细菌性病原体，在动物和人类中广泛存在。立克次体病在全世界都是一个公共卫生问题。然而，世界上大部分地区缺乏有关不同立克次体种类的地理分布、储库、病媒和人类病例感染状况的全面信息。因此，本研究旨在调查不同立克次体菌种及其病媒在世界卫生组织-东地中海区域组织地区各国的地理分布情况：在这项回顾性研究中，我们在各种数据库中搜索了1995年至2022年期间世卫组织-东地中海区域组织国家关于立克次体的报告和已发表的研究。最后，记录了不同国家与每种立克次体相关的人类病例、蓄积体和病媒的报告情况：结果：在22个世卫组织-东地中海区域办事处成员国中，只有15个国家提供了与检测到的立克次体有关的感染报告。共有24种立克次体，包括R. sibrica、R. lusitaniae、R. africae、R. prowazekii、R. felis、R. typhi、R. rickettsii、R. aeschlimannii、R. conorii、R. massiliae、R. helvetica、R. monacensis、R. rhipicephali、R.在世卫组织-欧洲微生物组织成员国中，报告了贝利虫（R. bellii）、阿森波尼虫（R. asembonensis）、霍格斯特拉尔虫（R. hoogstraalii）、安第斯虫（R. andeanae）、拉乌尔蒂虫（R. raoultii）、亚西亚虫（R. asiatica）、斯洛瓦卡虫（R. slovaca）、奥斯特虫（R. australis）、巴巴利虫（R. barbariae）、伏牛虫（R. amblyommii）和金瓦瑟虫（R. goldwasserii）。此外，这些国家还报告了感染六种不同立克次体的人类病例，包括R. sibrica、R. prowazekii、R. felis、R. typhi、R. rickettsii、R. aeschlimannii、R. conorii、R. massiliae和R. helvetica：结论：立克次体传播媒介的多样性有助于不断发现新的立克次体种类。因此，在研究不足的世卫组织-东地中海区域，进一步研究立克次体感染的蓄积宿主至关重要。这项研究揭示了立克次体病在该地区的流行病学和传播动态。
