Anaplasma capra is an emerging tickborne zoonotic pathogen in the genus Anaplasma, family Anaplasmataceae, and was initially identified in blood samples from asymptomatic goats (Capra aegagrus hircus) and a febrile [...]

Severe fever with thrombocytopenia syndrome (SFTS) is caused by SFTS virus (SFTSV), a new tickborne bandavirus identified in China in 2009 (1), and subsequently in South Korea in 2013 (2), [...]

Borrelia miyamotoi is an emerging pathogen first identified in Ixodes persulcatus ticks and rodents from Japan in 1994 (1,2). Since then, this bacterium has been discovered in various other Ixodes [...]

Ebola virus disease (EVD) is a severe, frequently fatal illness. In March 2014, the largest EVD outbreak in history began spreading through parts of West Africa. As of June 21, [...]

To identify Candidatus Neoehrlichia mikurensis infection in northeastern China, we tested blood samples from 622 febrile patients. We identified in 7 infected patients and natural foci for this bacterium. Field [...]

Rickettsia raoultii was first detected in Rhipicephalus pumilio and Dermacentor nuttalli ticks from the former Soviet Union in 1999 and initially named RpA4, DnS14, and DnS28 (1). In 2008, it [...]

To the Editor: Anaplasma phagocytophilum, an emerging human pathogen of public health importance, is transmitted to humans most commonly by tick bites (1). The agent has been detected in various [...]

To the Editor: Brucellosis is one of the most common zoonotic diseases worldwide (1). The disease is caused by Brucella spp. and mainly transmitted from its animal reservoirs to humans [...]

To the Editor: Babesiosis, which is caused by intraerythrocytic sporozoites of the genus Babesia, is a tick-borne emerging zoonosis in humans. Although >100 Babesia species infect animals, only a few [...]

To characterize the strains of Anaplasma phagocytophilum in wild and domestic animals in China, we isolated the organism from rodents and sheep in northeastern China. We isolated 3 strains (2 from rodents and 1 from sick sheep) through propagation in BALB/c mice and then cell culture in HL60 cells. The 3 isolates were identified by Wright-Giemsa staining, immunofluorescence, and electronic microscopy and were characterized by sequence analyses of the 16S rRNA gene, partial citrate synthase gene, major surface protein 4 gene, and heat shock protein gene. The multiple sequences of the 3 isolates were identical to each other but different from all known strains from other countries. The public health and veterinary relevance of the isolates deserves further investigation.
