Comprehensive surveillance of the antibody response to Borrelia burgdorferi s.l. in small ruminants in China
Journal Title: Annals of Agricultural and Environmental Medicine - Year 2015, Vol 22, Issue 2
Abstract
[i]Borrelia burgdorferi[/i] sensu lato, the etiological agent of Lyme disease, is tick transmitted and has a wide range of mammalian reservoirs in nature, including both wild and domestic animals. To understand the seroprevalence of [i]B. burgdorferi[/i] s.l. in small ruminants will add value to the risk analysis of Lyme disease. The current study was intended to map the potential endemic regions of Lyme disease by large-scale investigation of sera from sheep and goats. In this study, a total of 2,758 serum samples from sheep and goats in 21 provinces located in 40 different districts of China were tested for antibodies against [i]B. burgdorferi[/i] s.l. by enzyme-linked immunosorbent assay. The results of this survey indicated that the overall prevalence of [i]B. burgdorferi[/i] s.l. infection ranges from 5.3 to 63.5 % (mean: 26.3%), and the infection was found in all provinces investigated. Generally, the positive rate declined from the south (34.7% in south and 32.4% in southwest) towards the north of China (18.4% in north, 16.5% in northeast and 17.2% in northwest). A significant difference was also observed in the infection rate between south and north (33.2% versus 17.4%, [i]P[/i]<0.001). This study presents a comprehensive investigation of the serological distribution of [i]B. burgdorferi[/i] s.l. in small ruminants in China.
