| [studies on the retention of r. burneti in rh. bursa and h. detritum ticks]. | the role played by ixodes ticks in the epizootiology and epidemiology of q fever was studied by following up the transphasal and transovarial passing of rickettsia burnetii in ticks of the rhipicephalus bursa and hyalomma detritum species. use was made of the 269th passage of the rickettsial strain bp, isolated in this country from sheep. the infection was followed up from larva ist generation to larva iind generation of the two ticks. in 10 out of the eleven samples of ticks studied there were ... | 1975 | 1240691 |
| prevalence of tick-borne zoonotic bacteria in questing adult ticks from northern spain. | a total of 691 questing adult ixodid ticks of the genera ixodes, haemaphysalis, dermacentor, and rhipicephalus were tested by polymerase chain reaction (pcr) and reverse line blot (rlb) for the presence of anaplasma phagocytophilum, coxiella burnetii, borrelia spp., and spotted fever group (sfg) rickettsiae. ticks were collected by blanket dragging during 2 sampling years (2003-2005) in 10 recreational areas in the basque country (northern spain). adult ticks were collected every month of the ye ... | 2008 | 18759563 |
| pathogens and symbionts in ticks: a survey on tick species distribution and presence of tick-transmitted micro-organisms in sardinia, italy. | a total of 1485 adult ticks were collected from mammalian hosts in south-eastern sardinia, italy, during the years 2007-2008. ticks were identified and tested by pcr analysis for presence of rickettsia species of the spotted fever group, ehrlichia canis, anaplasma phagocytophilum, coxiella burnetii, bartonella species and leishmania species. among all tick species examined (rhipicephalus sanguineus, rhipicephalus turanicus, rhipicephalus bursa, rhipicephalus pusillus, hyalomma marginatum margina ... | 2010 | 20884769 |
| tick-borne bacteria in mouflons and their ectoparasites in cyprus. | the cypriot mouflon (ovis orientalis ophion), a once almost extirpated species of wild sheep, is under strict surveillance because it can be threatened by likely transmission of pathogenic bacteria, such as anaplasma spp., rickettsia spp., and coxiella burnetii, primarily from domestic ungulates. we collected 77 blood samples from cypriot mouflons and 663 of their ectoparasites (rhipicephalus turanicus, rhipicephalus sanguineus, rhipicephalus bursa, hyalomma anatolicum excavatum, hyalomma margin ... | 2011 | 21441182 |
| molecular evidence of tick-borne hemoprotozoan-parasites (theileria ovis and babesia ovis) and bacteria in ticks and blood from small ruminants in northern algeria. | using qpcr, standard pcr and/or sequencing, we investigated the presence of tick-associated microorganisms in ticks and blood from sheep and goats from souk ahras, algeria. borrelia theileri, was detected in (7/120, 5.8%) blood from sheep and (13/120, 10.8%) goats. anaplasma ovis was screened in (38/73, 52%) rhipicephalus bursa and (5/22, 22.7%) r. turanicus and in (74/120, 61.7%), (65/120, 54.2%) blood of sheep and goats respectively. coxiella burnetii tested positive in r. bursa (4/73, 5.5%) a ... | 2017 | 28131376 |
| bacterial pathogens and endosymbionts in ticks. | ticks collected from goats in northern greece were tested for the presence of tick-borne bacteria. among adult ticks, 37 (57.8%) were rhipicephalus bursa, 11 (17.2%) dermacentor marginatus, 10 (15.6%) ixodes ricinus, 3 (4.7%) rhipicephalus sanguineus sensu lato and 2 (3.1%) haemaphysalis parva; one (1.6%) rhipicephalus spp. tick was nymph. rickettsia monacensis, rickettsia massilae, anaplasma phagocytophilum and anaplasma platys were detected in i. ricinus and rh. bursa ticks. a variety of coxie ... | 2017 | 27686386 |
| pcr screening of tick-borne agents in sensitive conservation areas, southeast portugal. | the southeast region of portugal, particularly the guadiana valley, is currently the reintroduction territory of lynx pardinus (iberian lynx), one of the most endangered felids in the world that is only found in the iberian peninsula. over the last century, populations have declined, placing l. pardinus at extremely high risk of extinction in the wild and relying on reintroduction projects. among the aspects taken into account in the establishment of new populations is the sanitary status of the ... | 2017 | 27894847 |
| coxiella-like endosymbiont associated to the "anatolian brown tick" rhipicephalus bursa in southern italy. | several different ticks have been reported to harbor microbes related to coxiella burnetii, the agent of the q fever. rhipicephalus bursa is an important vector of tick-borne diseases in livestock in mediterranean area; it is also abundant in ovi-caprine farms with c. burnetii infection, in southern italy. 60 females of rh. bursa (15 pools) and 40 their eggs (2 pools) were screened for c. burnetii by a conventional pcr targeting the insertion sequence is1111 and by loop mediated isothermal ampli ... | 2016 | 26428855 |
