Babesia motasi BQ1 (Lintan) was first isolated from Haemaphysalis qinghaiensis collected in Gannan Tibet Autonomous Region, Gansu province in April 2000. In this study, a total of 3,204 serum samples from small ruminants in 22 provinces located in different districts of China were tested for antibodies against merozoite antigens from cultured B. motasi BQ1 (Lintan) by enzyme-linked immunosorbent assay. This method can survey the prevalence of low-pathogenic Chinese B. motasi. The results of this survey indicated that the average positive rate was 43.5 %, and the positive rates of investigated provinces were significantly different from 6.1 to 91.0 %, and the infections had been found in all provinces investigated. Our data provide large important information regarding the current sero-prevalence of B. motasi in China.

Eosinophilic panniculitis, characterized by a prominent infiltration of subcutaneous fat with eosinophils, has been identified in patients with a variety of associated clinical conditions. Burket and Burket reported the first case in 1985.1 To our knowledge, more than 30 additional patients have been described since this initial case report. The study of 18 patients with biopsy diagnoses of eosinophilic panniculitis by Winkelmann, et al. in 1986 revealed diverse patterns of systemic disease, including Wells’ syndrome, vasculitis, atopy, and erythema nodosum.2 We report three male patients of eosinophilic panniculitis with various clinical signs, two of whom had history of trauma or tuberculous pleurisy.
