This study was aimed to disclose the prevalence rate of tick-borne pathogens from ticks collected from cattle and wild animals in Tanzania in 2012. Ticks were collected from slaughtered cattle and dead wild animals from November 5 to December 23, 2012 and identified. PCR for detecting Anaplasmataceae, Piroplamidae, Rickettsiaceae, Borrelia spp., and Coxiella spp. were done. Among those tested, Rickettsiaceae, Piroplasmidae, and Anaplasmataceae, were detected in ticks from the 2 regions. Rickettsiaceae represented the major tick-borne pathogens of the 2 regions. Ticks from animals in Maswa were associated with a higher pathogen detection rate compared to that in ticks from Iringa. In addition, a higher pathogen detection rate was observed in ticks infesting cattle than in ticks infesting wild animals. All examined ticks of the genus Amblyomma were infected with diverse pathogens. Ticks of the genera Rhipicephalus and Hyalomma were infected with 1 or 2 pathogens. Collectively, this study provides important information regarding differences in pathogen status among various regions, hosts, and tick species in Tanzania. Results in this study will affect the programs to prevent tick-borne diseases (TBD) of humans and livestock in Tanzania.

문제 정의
In this study, we identified the TBD-causing pathogens transmitted from ticks that were collected from cattle and wild animals from these 2 areas. Results in this study can provide important information for the establishment of TBD prevention programs in these areas.
This study is the first report of ticks and tick-borne pathogens in cattle and wild animals of Maswa and Iringa regions, Tanzania. We focused on comparing pathogens between the 2 regions, between cattle and wild animals, and among tick species.
Since livestock and wild animals share habitats and grassland in these regions, studies are necessary to determine if ticks can transmit pathogens between livestock and wildlife, and even to humans in the region. This study provides very important information and basic knowledge that is necessary to initiate TBD prevention programs in these areas.
대상 데이터
Among the 300 ticks examined, pathogens were detected by PCR in 187 (60.7%) ticks (Table 1). Ticks from animals of Maswa exhibited a 77.
Ticks collected from the cattle and wild animals (buffalo, bush pig, eland, leopard, warthog, and zebra) from Maswa Game Reserve and Iringa urban, Tanzania from November 5 to 23, 2012 [1] were used in this study. Collected ticks were fixed with EtOH, and transferred from Tanzania to Yonsei University, Korea.
이론/모형
Differences in pathogen detection were tested by a Fisher’s exact test.
성능/효과
In this study, the detection rates of Anaplasmataceae and Piroplasmidae were very low compared to those of Rickettsiaceae. However, the detection rates of Anaplasma marginale and Babesia bigemina in bovine blood in Iringa reached 37% and 43%, respectively [4,5].
Rickettsiaceae was the most common family of pathogens identified in ticks from both regions. Rickettsiaceae (R. africae, R. rickettsii, and uncertain Rickettsiaceae) was detected in 146 ticks, and from all animals examined except warthog. Rickettsiaceae detection rates were 65.
variegatum ticks [1], the most predominant tick species, were infected with pathogens. The second most predominant species, namely A. gemma, was associated with a 25% (18/72) pathogen detection rate. Amblyomma ticks were infected with diverse pathogens, whereas Rhipicephalus and Hyalomma ticks were generally infected by a single Rickettsia species.
