Abstract
A survey has been conducted in Bukavu on bovines imported in Democratic Republic of Congo from Rwanda to the public slaughterhouse of Bukavu, with the aim of identifying the Ixodidae ticks on their body. Thus, 1024 ticks have been collected on 300 cows for the entomological identification. Four species have been identified whose Boophilus decoloratus (44.4 %), Rhipicephalus appendiculatus (43.9 %), Amblyomma variegatum (11 %) and Ixodes thomasai (2 %). This last species being a new among those recognized in South Kivu. A charge to ticks of 6.5 has been observed at those bovines and the infestation rate has been significantly different in the 4 races, the Friesland (41.1 %) and Ankolé presented the superior values. The importation of cows in this part of the country from Rwanda is a real factor which conducts to the introduction of ticks and also diseases in Democratic Republic of Congo. Then being measures of heath control in the border must be sustained and reinforced for minimizing real risks.
Highlights
IntroductionThe work carried out by Bisusa and Rucacura on ticks in cattle in the Ruzizi plain noted the presence of Hyalomma truncantum [2]
Mismanagement and insufficient means of preventing animal diseases at the border is the basis for the introduction of several pathogens in many countries in Africa
For the Friesians we identified a total of 500 ticks or 44.4 % including 95 males, 90 females and 43 nymphs (Rhipicephalus appendiculatus), 9 males, 114 Females and 67 nymphs (Boophilus decoloratus), 67 males, females, and 11nymphs (Amblyomma variegatum) and only 7 females (Ixodes thomasai)
Summary
The work carried out by Bisusa and Rucacura on ticks in cattle in the Ruzizi plain noted the presence of Hyalomma truncantum [2]. The introduction into this breeding area was linked to the importation of cattle from Burundi and Tanzania. Ticks are obligate blood-sucking arthropods and represent one of the major constraints to the development of animal husbandry in Africa as elsewhere in the world [5, 7] They are sources of direct actions, such as skin irritations and blood spoliations, and of indirect effects such as the transmission of pathogenic agents such as viruses, neuroviruses, bacteria and nematodes [8]
