A total of 310 blood smears were collected from sheep of the Livestock Experiment Station, Qadirabad, Sahiwal district, Pakistan, and surrounding areas. The samples were examined microscopically and 30 (9.67%) were positive for babesiosis. The animals were divided into two groups (A and B) for chemotherapy. Group A sheep were treated with diminazene diaceturate while group B animals received imidocarb dipropionate. Drug efficacy was determined by negative blood smear examination. Diminazene diaceturate effectiveness against babesiosis was 80% while that of imidocarb dipropionate was 100%. Hematological studies revealed a significant decrease in hemoglobin concentrations and hematocrit values for Babesia-positive animals compared to healthy controls.

Ticks and tick-borne infections pose major economic threats to the livestock industry throughout the world. The present study reports the point prevalence of ticks in the free range livestock population of the plain and hilly areas of Khyber Pakhtunkhwa (Mansehra, Haripur, Shangala, Kohistan), and Gilgit Baltistan (Diamer, Gilgit, Astor) along the Karakoram highway. Through convenient and snowball sampling techniques, a total of 813 animals, consisting of 232 sheep, 163 cattle, 365 goats and 53 buffaloes were screened for their tick burden. During the study, the two tick species identified were Hyalomma anatolicum and Rhipicephalus microplus. The overall prevalence of tick infestation among the screened livestock was 75.03%, with the highest distribution in sheep (81.47%) followed, in order, by cattle (77.91%), goats (72.05%) and buffalo (58.49%). The district-wise prevalence of ticks was the highest in Haripur (85.58), followed, in order, by Gilgit (83.10%), Mansehra (81.14%), Batagram (81.05%), Shangala (77.78%), Kohistan (75.38%), Diamer (72.28%) and Astor (32.22%). The prevalence of ticks was found to be higher (85.67%) in younger livestock than adults (66.44%), and in females (80.33%) than males (66.44%). The present study provides the first report of the tick distribution in higher altitudes of northern Pakistan and confirms the presence of Hyalomma and Rhipicephalus ticks in the plains, as well as the hilly geoclimates of Pakistan. Furthermore, the data on risk factors allows us to make recommendations to restructure the existing husbandry system of northern areas of Pakistan with the aim of reducing the tick burden on livestock.

“…Damage is either direct (skin lesions, impairment of animal growth) or indirect, resulting from transmission of a variety of pathogens (32). Major economical impact has been associated with the tick-borne diseases anaplasmosis, heartwater, babesiosis, and theileriosis, all of which are prevalent in Africa (4).…”

“…Anaplasma species are commonly detected in cattle, and seroprevalence rates between 4.6% (Kenya) and 98% (South Africa) from different sub-Saharan countries have been reported (4,18,26,31). The causative agents of bovine babesiosis and theileriosis have frequently been detected in blood smears from cattle in Ghana, with prevalences as high as 97% for Theileria mutans, 87% for Theileria velifera, and 61% for Babesia bigemina (4). Tick-borne human ehrlichiosis of varying severity is caused by Ehrlichia chaffeensis and Ehrlichia ewingii (24).…”

ABSTRACTTicks are important disease vectors that can cause considerable economic losses by affecting animal health and productivity, especially in tropical and subtropical regions. In this study, we investigated the prevalence and diversity of bacterial and protozoan tick-borne pathogens in ticks collected from the vegetation and cattle in Nigeria by PCR. The infection rates of questing ticks were 3.1% forRickettsiaspecies, 0.1% forCoxiella burnetiiand 0.4% forBorreliaspecies. Other pathogens, such asBabesia,Theileria,Anaplasma, andEhrlichiaspecies, were not detected in ticks from the vegetation. Feeding ticks collected from cattle displayed infection rates of 12.5% forRickettsiaspecies, 14% forCoxiella burnetii, 5.9% forAnaplasmaspecies, 5.1% forEhrlichiaspecies, and 2.9% forTheileria mutans. BabesiaandBorreliaspecies were not detected in ticks collected from cattle. Mixed infections were found only in feeding ticks and mainlyRickettsiaspecies andCoxiella burnetiiwere involved. The diversity of tick-borne pathogens in Nigeria was higher in feeding than in questing ticks, suggesting that cattle serve as reservoirs for at least some of the pathogens studied, in particularC. burnetii. The total estimated herd infection rates of 20.6% for aRickettsia africae-like species, 27% forCoxiella burnetii, and 8.5% forAnaplasma marginale/centralesuggest that these pathogens may have considerable implications for human and animal health.
