Abstract

Sheep, cattle and the African buffalo (Syncerus caffer) were shown to remain carriers of heartwater (caused by Cowdria ruminantium) for long periods after recovery; 223, 246 and 161 days, respectively. Transmission was achieved using adults of the southern African bont tick (Amblyomma hebraeum) that had fed as nymphs on recovered animals. Our findings differ from those of other workers who attempted transmission using nymphs that had fed as larvae on recovered animals or with blood from recovered animals.

    However, the present study did not detect any species of Ehrlichia or Rickettsia in any of the cattle samples analyzed. The absence of Ehrlichia in our samples may be attributed to the biology of Ehrlichia species, as it mainly resides in endothelial cells and is only periodically found in the bloodstream during the febrile stage of infection (Andrew and Norval, 1989; Steyn et al., 2008). The absence of R. africae corroborates previous studies in western Kenya that recorded no evidence of pathogenic rickettsial species in blood samples collected from livestock (Chiuya et al., 2021; Maina et al., 2014; Okal et al., 2020).

    The majority of the sub-Saharan Africa countries are considered endemically stable for heartwater (Deem et al., 1996). Consequently, ticks in the field generally exhibit low infection rates (Allsopp, 2010) and infected animals are often asymptomatic, carrying the pathogen at very low levels (Andrew and Norval, 1989). Considering that E. ruminantium mainly resides in endothelial cells and can only be periodically found in the bloodstream, low prevalence rates based on PCR assays from blood samples are expected (Andrew and Norval, 1989; Lorusso et al., 2016).

    This might be attributed by the biological nature of the pathogen. It has been reported the pathogen resides mostly in endothelial cells of blood vessels and is only periodically found in the blood stream (Andrew and Norval, 1989; Lorusso et al., 2016). The presence of this pathogen together with its vector (Amblyomma ticks) reported by Mamiro et al., (2016) in Tanzania should be taken into account when considering to improve breeds, by introducing exotic breeds of cattle (Bos taurus).

    Much of sub-Saharan Africa, is considered endemically stable for heartwater (Deem et al., 1996). Consequently, ticks in the field generally exhibit low infection rates (Allsopp, 2010) and infected animals are often asymptomatic, carrying the rickettsia at very low levels (Andrew and Norval, 1989). The average infection rates among Benin A. variegatum is 10.8% (range: 8.9-15.6%) (Farougou et al., 2012).
