Ticks are blood-sucking arthropods established in basically all global regions of the world. Around the world, there are about 900 species of ticks. Ixodid or hard ticks are University, Baghdad, Iraq; 3 Department of Biology, Science College, Baghdad University, Baghdad, Iraq made about 700 species, while 200 species are soft ticks. Ticks act as vectors of a wide range of disease agents, including viruses, bacteria, and protozoa. It is well documented that more than 100 000 diseased conditions in a human being in the world are associated with the tick- borne infection. This study intended to isolate some enterobacteriacae (Escherichia coli and Salmonella spp) from live adult female Rhipicephalus spp hard tick. Sixty-seven ticks were collected from cattle and sheep during the period extended from November 2015 till March 2016 from Baghdad governorate. Totally, there were 15 (22.38%) samples revealed bacterial isolates out of 67. The number and percentage of E. coli, Salmonella spp and both E. coli and Salmonella spp isolates were 10 (14.92 %), 2 (2.98 %) and 3 (4.47 %) respectively. Moreover, the results showed significant (P ≤ 0.05) difference between the isolated bacteria. In conclusion, this study approved the isolation of Escherichia coli and Salmonella spp from adult female Rhipicephalus spp hard tick. The author recommends taking a prevention precaution to control the distribution of ticks that have serious roles in the transmission and distribution of bacterial diseases in domestics animals.
