Ethiopia has the largest livestock population in Africa, but the contribution for the economic aspect of the country is still lowest and disease can be considered as major constrain. Ticks are the most important ectoparasites of livestock in tropical and sub-tropical areas. Ethiopia is not exceptional and ticks are responsible for severe economic losses both through the direct effects of blood ...

BACKGROUND Coxiella burnetii, the etiologic agent of Q fever, is a highly infectious zoonotic bacterium. Genetic information about the strains of this worldwide distributed agent circulating on the African continent is limited. The aim of the present study was the genetic characterization of C. burnetii DNA samples detected in ticks collected from Ethiopian cattle and their comparison with othe...

Anaplasma marginale Theiler is a tick-borne rickettsial pathogen of cattle with a global distribution in both temperate and tropical regions. The pathogen is endemic in regions within the United States, whereas the Canadian cattle population is considered to be free ofA. marginale. Farmed bison, Bison bison L., in central Saskatchewan have been found to be infected with A. marginale; however, t...

Parasitic diseases, like babesiosis and theileriosis are transmitted by ticks: their occurrence is therefore linked to the size of the tick stock and the seasonality of the vectors. Babesia divergens bovine babesiosis transmitted by Ixodes ricinus is widespread and often reported in France. Serological prevalence is high, ranging from 20 to 80% according to the farms. Clinical incidence is low:...

Canadian Council of Ministers of the Environment, 2012 Trichlorfon (CAS 52-68-6) is an organophosphate insecticide used to control pests such as cockroaches, crickets, silverfish, bedbugs, fleas, cattle grubs, flies, ticks, leafminers and leaf-hoppers (EXTOXNET, 1996). Trichlorfon is manufactured by Bayer CropScience Inc. and is produced in soluble powder, granular, emulsifiable concentrate, an...

The cattle tick Rhipicephalus (Boophilus) microplus is responsible for major losses in the Brazilian livestock, mainly due to reduction in cattle productive performance. Resistance development to major classes of acaricide widely used nowadays has been extensively reported, as well as the occurrence of residues from these compounds in animal products and the environment. This study aimed to eva...

A total number of 450 blood samples were collected from 45 different randomly selected cattle herds. Light microscopic examination of blood smears revealed Babesia spp. infection in 4.2%, while 8.9% of blood samples were positive using PCR. Upon multiplex-PCR (mPCR), B. bigemina and B. bovis infections were detected in 37/40 (92.5%) and 3/40 (7.5%) samples, respectively. 530 ticks of 10 Ixodid ...

Information on the traditional tick control methods used in Keffa, Illubabor and Wellega Provinces in western Ethiopia was obtained from 86 veterinary clinics and 865 peasant farmers through a questionnaire survey. Latexes of Euphorbia obovalifolia and Ficus brachypoda, juice of crushed leaves of Phytolaca dodecandra and Vernonia amygdalina, fruit juice of Solanum incanum, crushed seeds of Lepi...

The study was conducted in a peri-urban agricultural system at Botshabelo, a city in the south-eastern Free State. A questionnaire survey revealed that 88.5% of cattle farmers in the area experienced problems related to ticks and tick-borne diseases. Because of the cost of commercial acaricides the Botshabelo farmers use alternative, cheaper methods of tick control, including the application of...
