distribution and ecology of ticks (acari: ixodidae) infesting livestock in tunisia: an overview of eighth years field collections.ticks (ixodidae) play a significant role as vectors of pathogens of domestic animals in tunisia. the major losses caused by ticks are related to transmission of protozoan parasites. these include agents of tropical theileriosis and babesiosis in ruminants. since 1991, we conducted research studies on tick population of livestock in tunisia. this overview reports a synthesis on tick distribution, their biology and their role as vectors of pathogens in domestic animals, particularly cattle. during ...199911071534

prevalence of vectors of the spotted fever group rickettsiae and murine typhus in a bedouin town in israel.a survey of the vectors of spotted fever group rickettsiae and of murine typhus was carried out in rahat, a bedouin town in the negev desert, where the diseases are endemic. houses with known cases of spotted fever group rickettsiae or murine typhus were compared with those without reported clinical cases. a neighboring jewish community, lehavim, where no cases of spotted fever group rickettsiae and murine typhus were reported in recent years, was used as a control. in the houses of patients wit ...200111372975
species composition, distribution, and ecological preferences of the ticks of grazing sheep in north-central spain.the distribution and ecological preferences of tick (acari: ixodidae) parasites of grazing sheep in the region of aragón (north-central spain) were surveyed on flocks four times a year and mapped into a 5 x 5 km grid. nine tick species were found. these were species of the rhipicephalus sanguineus group (about 95% of them rhipicephalus turanicus pomerantsev, in 91% of cells of the grid), rhipicephalus bursa canestrini & fanzago (79% of cells), dermacentor marginatus (sulzer) (58% of cells), haem ...200415189237

rickettsia sibirica isolation from a patient and detection in ticks, portugal.we report the first isolation of rickettsia sibirica (strain mongolotimonae) from the blood of a patient and detection by polymerase chain reaction (pcr) of the rickettsia in a rhipicephalus pusillus tick collected from a dead mongoose (herpestes ichneumon) in the alentejo region, portugal. we describe also the first pcr detection of a new rickettsia strain that is related to r. sibirica.200616836827
rickettsial agents in egyptian ticks collected from domestic animals.to assess the presence of rickettsial pathogens in ticks from egypt, we collected ticks from domestic and peridomestic animals between june 2002 and july 2003. dna extracts from 1019 ticks were tested, using pcr and sequencing, for anaplasma spp., bartonella spp., coxiella burnetii, ehrlichia spp., and rickettsia spp. ticks included: 29 argas persicus, 10 hyalomma anatolicum anatolicum, 55 hyalomma anatolicum excavatum, 174 hyalomma dromedarii, 2 hyalomma impeltatum, 3 hyalomma marginatum rufipe ...200617004028
tick-borne zoonotic bacteria in wild and domestic small mammals in northern spain.the prevalence and diversity of tick-borne zoonotic bacteria (borrelia spp., anaplasma phagocytophilum, coxiella burnetii, and spotted fever group rickettsiae) infecting 253 small mammals captured in the basque country (spain) were assessed using pcr and reverse line blot hybridization. trapping sites were selected around sheep farms (study 1, 2000 to 2002) and recreational parks (study 2, 2003 to 2005). the majority of the studied mammals (162) were wood mice (apodemus sylvaticus), but six othe ...200717693556
a survey of ticks (acari:ixodidae) on cattle, sheep and goats in the dohuk governorate, iraq.a survey on hard ticks affecting cattle, sheep, and goats was done in dohuk governorate from march 2005 until february 2006 in three areas (dohuk surrounding area, barwary balla near turkish border, and eqre). the species collected from cattle were hyalomma anatolicum anatolicum and hyalomma anatolicum marginatum, while the species collected from sheep and goats were rhipicephalus bursa, rhipicephalus turanicus, haemaphysalis parva, and hyalomma spp. the occurrences of the ticks in the three are ...200717823824
ticks infesting domestic animals in northern greece.the tick species infesting grazing animals in the countryside of 11 prefectures in northern greece were investigated during april-july and september-december of consecutive years 2003-2006. a total of 3,249 (1,952 males, 1,297 females) adult ticks were collected from goats, sheep, cattle and dogs. ticks were identified as ixodes ricinus (44.57%), ixodes gibbosus (4.09%), rhipicephalus bursa (19.14%), rhipicephalus sanguineus, rhipicephalus turanicus (5.79%), hyalomma marginatum marginatum (12.40 ...200818563592

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 ...201121441182
spotted fever group rickettsiae in ticks in cyprus.in two surveys conducted from march 1999 to march 2001 and from january 2004 to december 2006, a total of 3,950 ticks (belonging to ten different species) were collected from seven domestic and wild animals (goat, sheep, cattle, dog, fox, hare, and mouflon) from different localities throughout cyprus. in order to establish their infection rate with spotted fever rickettsiae (sfg), ticks were pooled and tested by polymerase chain reaction targeting glta and ompa genes, followed by sequencing anal ...201121833539
dermacentor reticulatus: a vector on the rise.dermacentor reticulatus is a hard tick species with extraordinary biological features. it has a high reproduction rate, a rapid developmental cycle, and is also able to overcome years of unfavourable conditions. dermacentor reticulatus can survive under water for several months and is cold-hardy even compared to other tick species. it has a wide host range: over 60 different wild and domesticated hosts are known for the three active developmental stages. its high adaptiveness gives an edge to th ...201627251148
the recent evolution of a maternally-inherited endosymbiont of ticks led to the emergence of the q fever pathogen, coxiella burnetii.q fever is a highly infectious disease with a worldwide distribution. its causative agent, the intracellular bacterium coxiella burnetii, infects a variety of vertebrate species, including humans. its evolutionary origin remains almost entirely unknown and uncertainty persists regarding the identity and lifestyle of its ancestors. a few tick species were recently found to harbor maternally-inherited coxiella-like organisms engaged in symbiotic interactions, but their relationships to the q fever ...201525978383
hard ticks (acari, ixodidae) of croatia.the present paper is based on original and literature data. in croatia the first studies on the occurrence of ixodid species were made about 80 years ago. the number of tick species recorded in croatia considerably increased during the 1950s, 60s, 70s and 80s of the past century. a total of 21 species of hard tick belonging to 5 genera have been recorded in croatia. ixodes is the best represented genus, with seven species recorded. haemaphysalis is represented by six species, followed by rhipice ...201223372407
a new multiple-locus variable-number tandem repeat analysis reveals different clusters for anaplasma phagocytophilum circulating in domestic and wild ruminants.anaplasma phagocytophilum is a tick-borne intragranulocytic alpha-proteobacterium. it is the causative agent of tick-borne fever in ruminants, and of human granulocytic anaplasmosis in humans, two diseases which are becoming increasingly recognized in europe and the usa. however, while several molecular typing tools have been developed over the last years, few of them are appropriate for in-depth exploration of the epidemiological cycle of this bacterium. therefore we have developed a multiple-l ...201425228371
