AbstractRhipicephalus microplus is an ixodid tick with a pantropical distribution that represents a serious threat to livestock. West Africa was free of this tick until 2007, when its introduction into Benin was reported. Shortly thereafter, the further invasion of this tick into West African countries was demonstrated. In this paper, we describe the first detection of R. microplus in Guinea and list the vector-borne haemoparasites that were detected in the invader and indigenous Boophilus species.In 2018, we conducted a small-scale survey of ticks infesting cattle in three administrative regions of Guinea: N`Zerekore, Faranah, and Kankan. The tick species were identified by examining their morphological characteristics and by sequencing their COI gene and ITS-2 gene fragments. R. microplus was found in each studied region. In the ticks, we found DNA of Babesia bigemina, Anaplasma marginale, Anaplasma platys, and Ehrlichia spp. The results of this study indicate that R. microplus was introduced into Guinea with cows from Mali and/or Ivory Coast.

Tick Burden

A total of 2809 ixodid ticks were collected by screening 4560 household cattle from six different agro-climatic zones of Tamil Nadu, a southern state of India. Among the ixodid ticks, Rhipicephalus microplus tick isolates were subjected to Adult Immersion Test (AIT) and Larval Packet Test (LPT) using deltamethrin. The mean % of ixodid tick infested cattle population was 63.2%±10.9. Positive correlation was found between the tick burden on household cattle and Resistance Factor (R=0.66). Further, 44% variance in the tick burden on cattle is explained by LPT based resistance factor suggesting deltamethrin resistance level is one of the contributing factors to the tick load on cattle. Analysis of DNA sequence of sodium channel gene domain II-S4-5 linker region of all deltamethrin resistant R. microplus tick isolates, confirmed the absence of point mutation at the 190th nucleotide which suggests the possible mutation in other regions of sodium channel gene of R. microplus tick isolates of south India and/or alternate resistance mechanisms.
