Ticks are obligate blood-sucking ectoparasites that transmit a variety of zoonotic pathogens through bites,which can cause substantial harm to human health and animal husbandry.With frequent international travel and global climate change,the con-tinued geographical expansion of ticks has attracted increasing attention,and tick-borne diseases have become an important public health issue.Guangdong Province is considered a global hotspot for the importation of emerging zoonotic and vector-borne diseases,because of its climate,environment,and biodiversity.Based on a literature review,this article summarizes and analyzes the main tick species and their distribution,the pathogens carried by ticks,and the prevalence of tick-borne diseases in humans and animals in Guangdong Province.The aim is to provide a reference for the prevention and control of ticks and tick-borne diseases in the area.

Infectious disease is a major public health problem threatening human health and social development, and infectious disease teaching is an important part of public health education. However, traditional infectious disease teaching faces challenges such as overly theoretical and fragmented content, overly traditional and monotonous methods, and a narrow and isolated vision, which makes it difficult to adapt to the current complex and changing situation of infectious disease prevention and control. The “One Health” concept emphasizes interdisciplinary, cross-sectoral, and cross-regional communication and cooperation to achieve the harmonious unity of health for humans, animals, and the environment, which is significant in preventing and controlling infectious diseases. This paper proposes some ideas for reforming infectious disease teaching based on the One Health concept, which aims to improve the quality and effectiveness of infectious disease teaching by recognizing the close connection between human health, animal health, and environmental health. Specifically, it is suggested to reform the teaching in four aspects: introducing the basic concepts, principles, and practices of One Health, increasing the content of infectious diseases related to One Health, adopting diversified and interactive teaching methods, and establishing cross-disciplinary teaching cooperation. Concrete recommendations are provided for each aspect. This paper argues that reforming infectious disease teaching based on the One Health concept is conducive to cultivating public health talents with global vision, systems thinking, and cross-disciplinary collaboration capabilities, providing robust talent support for coping with emerging, re-emerging, and endemic infectious disease threats.

Anaplasma capra, an emerged tick?borne agent, maintained its natural cycles via ticks and host reserviors. To survey for A. capra infection in Haemaphysalis longicornis in North China, a total of 311 H. longicornis ( 95 adults, 156 nymphs, 60 larvae) were collected in Beijing during May to Sept. in 2012 and 2015. A. capra was identified from 3 adults (3?2%) when amplified by PCR targeting gltA gene and rrs (16S rRNA). No infection was found in the nymphs and larvae. Phylogenetic analyses revealed that the partial gltA and 16S rRNA sequences obtained in the ticks are identical to A. capra harvseted from Mudanjiang′s patients in 2014. The finding of A. capra in ticks in North China indicates the natural foci may exist in North China and it is urgent and necessary to prevent and control the emerged tick borne disease in this area.
