| host resistance to ticks (acari: ixodidae) in different breeds of cattle at bako, ethiopia. | european cattle breeds are being introduced into ethiopia in an effort to improve the productivity of indigenous breeds. the ethiopian cattle breeds horro and boran were compared for tick burdens with their crosses with friesian, jersey and simmental. horro animals had the lowest tick burdens and the horro x friesian the highest. adaptation to their environment and long-term natural selection for tick resistance in horro cattle is the most likely explanation. repeatability of tick burdens in all ... | 1993 | 8109054 |
| tick infestation of borana cattle in the borana province of ethiopia. | a study was conducted to identify and determine burdens of ticks infesting borana cattle in the borana province of ethiopia. rhipicephalus pulchellus, rhipicephalus pravus, rhipicephalus muhsamae, rhipicephalus praetextatus, rhipicephalus evertsi evertsi, amblyomma gemma, amblyomma variegatum, amblyomma cohaerens, amblyomma lepidum, hyalomma truncatum, hyalomma marginatum rufipes and boophilus decoloratus were identified on the cattle. their burdens ranged from 658-1,554 with a mean of 1,205 tic ... | 2001 | 11403429 |
| ticks (acari: ixodidae) infesting camels (camelus dromedarius) in northern sudan. | monthly total body tick collections from 13-20 camels were conducted for 2 consecutive years (2000-2001) in northern sudan. tick populations were correlated with locality, season, predeliction site, sex and coat colour. hyalomma dromedarii was found to be the predominant (89%) tick species infesting the camels. other tick species found in very low numbers were hyalomma impeltatum (7.7%), hyalomma anatolicum anatolicum (3.3%), hyalomma truncatum (0.29%), hyalomma marginatum rufipes (0.25%), rhipi ... | 2009 | 20698438 |
| infection and exposure to vector-borne pathogens in rural dogs and their ticks, uganda. | in rural parts of africa, dogs live in close association with humans and livestock, roam freely, and usually do not receive prophylactic measures. thus, they are a source of infectious disease for humans and for wildlife such as protected carnivores. in 2011, an epidemiological study was carried out around three conservation areas in uganda to detect the presence and determine the prevalence of vector-borne pathogens in rural dogs and associated ticks to evaluate the risk that these pathogens po ... | 2015 | 26043771 |
| detection of a new borrelia species in ticks taken from cattle in southwest ethiopia. | we collected 284 ticks in ethiopia (109 amblyomma cohaerens, 173 rhipicephalus decoloratus, and 2 rhipicephalus praetextatus). we found no rickettsiae and bartonellae. in 7.3% of the a. cohaerens, we found a borrelia sp. that may represent a new species distant from both relapsing fever group and lyme borreliae. | 2013 | 23421894 |
| cattle and rainfall affect tick abundance in central kenya. | east africa is a global hot spot for the diversity of ixodid ticks. as ectoparasites and as vectors of pathogens, ticks negatively affect the well-being of humans, livestock and wildlife. to prevent tick infestations, livestock owners and managers typically treat livestock with acaricides that kill ticks when they attempt to feed on livestock hosts. because of the costs of preventing and mitigating tick parasitism, predicting where and when ticks will be abundant is an important challenge in thi ... | 2017 | 29113602 |
| morphological, molecular and maldi-tof mass spectrometry identification of ixodid tick species collected in oromia, ethiopia. | matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (maldi-tof ms) technology has recently been reported as a promising method for arthropods identification. more recently, our laboratory reported the correct identification of tick species via the maldi-tof ms protein spectra profiling of legs from fresh specimens. the aim of the present study was to assess the use of maldi-tof ms for correct identification of ixodid tick species preserved in 70 % ethanol during field co ... | 2016 | 27469536 |
| spotted fever group rickettsiae in ixodid ticks in oromia, ethiopia. | in ethiopia, information on the transmission of human zoonotic pathogens through ixodid ticks remains scarce. to address the occurrence and molecular identity of spotted fever group rickettsiae using molecular tools, a total of 767 ixodid ticks belonging to thirteen different species were collected from domestic animals from september 2011 to march 2014. rickettsia africae dna was detected in 30.2% (16/53) amblyommma variegatum, 28.6% (12/42) am. gemma, 0.8% (1/119) am. cohaerens, 18.2% (4/22) a ... | 2015 | 25262832 |
| ectoparasites of sheep in three agro-ecological zones in central oromia, ethiopia. | a cross-sectional study was conducted to determine the prevalence and risk factors for ectoparasites infestation in sheep in three agro-ecological zones in central oromia, ethiopia, from october 2009 to april 2010. the study revealed that 637 (48.1%) of the 1325 sheep examined were infested with one or more ectoparasites. the ectoparasites identified were bovicola ovis (27.2%), melophagus ovinus (16.4%), ctenocephalides sp. (2.3%), linognathus africanus (1.2%), linognathus ovillus (0.3%), sarcop ... | 2012 | 23327319 |
| ticks (acari: ixodidae) infesting cattle and african buffaloes in the tsavo conservation area, kenya. | several ixodid tick species are shared between domestic cattle and african buffaloes (syncerus caffer). so too, are a number of tick-borne diseases. the aim of the study was to compare the species composition of ticks that infest cattle and buffaloes utilising the same habitat within the tsavo conservation area, kenya. to this end, 25 cattle and 62 buffaloes were each opportunistically sampled for ticks on a single occasion in february 2010. eight species, namely amblyomma gemma, amblyomma lepid ... | 2012 | 23327329 |
| reliminary survey of ticks (acari: ixodidae) on cattle in central equatoria state, southern sudan. | in a preliminary survey conducted in 2005, the species composition and seasonality of ticks infesting cattle in central equatoria state, southern sudan was determined. three locations were selected (gumbo, khor rumla and nyaing) and surveyed every 3 months. two cattle herds in each of the three locations were visited four times during the study period. total body collections of ticks were made from each of five cattle (nilotic zebu breed) kept in six different herds. four tick genera and ten spe ... | 2008 | 18575063 |
