evaluation of the efficacy of fospirate-treated collars against the brown dog tick.	experimental tick infestations on dogs were done to determine the initial kill and residual effectiveness of a 15% fospirate-treated plastic colar against the brown dog tick, rhipicephalus sanguineus (latreille). the mean initial kill, determined 4 days after collar application (day 4), was 56.4%. the mean residual effectiveness of fospirate collars on test days 18, 33, 45, 61, 74, 88, and 112 was 89.1, 77.4, 89.5, 78.6, 73.2, 69.0, and 55.0% control, respectively.	1976	984550
development of ehrlichia canis, causative agent of canine ehrlichiosis, in the tick rhipicephalus sanguineus and its differentiation from a symbiotic rickettsia.	certain aspects of the development of ehrlichia canis, causative agent of canine ehrlichiosis (tropical canine pancytopenia) in rhipicephalus sanguineus ticks were studied. it was found that partial feeding of nymphs infected as larvae with e canis was a desirable, if not necessary, preliminary treatment for successful infection of dogs with ground-up ticks. it remains unclear whether feeding increased the number or altered the virulence of ehrlichiae within tick tissues. ehrlichia canis organis ...	1976	944000

possibilities of persistence in new biotopes of ticks imported by birds.	survival and development of 6 tick species (hyalomma anatolicum, rhipicephalus sanguineus, haemaphysalis punctata, dermacentor marginatus, d. reticulatus and ixodes ricinus) were studied in 3 groups differing in the range of distribution with respect to the place of importation, as a model for the knowledge of their possible inclusion in the new local biocenosis during transportation by natural hosts.	1977	852771

rocky mountain spotted fever in mississippi: survey for spotted fever antibodies in dogs and for spotted fever group reckettsiae in dog ticks.	during epidemiologic studies of rocky mountain spotted fever in mississippi in 1973, dogs were surveyed for antibodies tp spotted fever group antigens and for tick parasites infected with rickettsiae of the spotted fever group. fifty-three (46%) of 116 serum samples had complement-fixing antibody titers greater than or equal to 1:8 as compared to only one (5%) of 21 samples from a group of dogs obtained from metropolitan chicage. fifty-two per cent of the dogs tested from mississippi had microag ...	1976	814809
rocky mountain spotted fever (tick-borne typhus) in south carolina: an educational program and tick/rickettsial survey in 1973 and 1974.	because the incidence of spotted fever is increasing in south carolina, campaigns were carried out in 1973 and 1974 to provide the public and medical practitioners, through pamphlets and news media, with information about spotted fever and the ticks which transmit the causative agent, rickettsia rickettsii. people were also invited to save and submit live ticks removed from vegetation, animals and humans, for examination by the hemolymph test. a total of 1,186 ticks consisting of 987 dermacentor ...	1975	811127
rhipicephalus sanguineus: vector of a new spotted fever group rickettsia in the united states.	a rickettsia related to but distinct from the spotted fever agent, rickettsia rickettsii, has been detected in 167 (18.9%) of 884 rhipicephalus sanguineus taken off dogs in central and northern mississippi. the organisms could readily be isolated in male meadow voles (microtus pennsylvanicus), where it produced massive infections in the tissues of tunica vaginalis. it was practically nonpathogenic for male guinea pigs, although inoculation of these animals with infected tunica vaginalis of voles ...	1975	806533
preparation of primary cultures of tick cells.	primary cell cultures were prepared from preimaginal bodies from the nymphal ticks, rhipicephalus sanguineus, dermacentor andersoni, and amblyomma maculatum, and from the hemocytes of late-stage nymphal and adult ticks, ornithodoros coriaceus. the dissection methods for obtaining preimaginal bodies and hemocytes for culture are described. a culture mediu, designated rml 375, was used for both culture methods. primary cultures were established with minimal contamination. preimaginal body cultures ...	1978	697169

the brown dog tick rhipicephalus sanguineus and the dog as experimental hosts of ehrlichia canis.	adult rhipicephalus sanguineus ticks efficiently transmitted ehrlichia canis to susceptible dogs for 155 days after detachment as engorged nymphs from a dog in the acute phase of ehrlichiosis. adult ticks that had similarly engorged on a dog in the chronic phase of ehrlichiosis failed to transmit e canis to susceptible dogs. infected but unfed adult ticks may be of greater importance than the chronically infected carrier dog as a natural reservoir of e canis.	1977	596693

ultrastructure of rickettsia rhipicephali, a new member of the spotted fever group rickettsiae in tissues of the host vector rhipicephalus sanguineus.	rickettsia rhipicephali is similar in ultrastructure to r. rickettsii while differing from other rickettsiae of the typhus group and of q fever and others by its lack of a prominently reticulated cytoplasmic matrix and in the thickness of the inner osmophilic layer of the cell wall. in tissues of the tick vector rhipicephalus sanguineus, r. rhipicephali had a mean length and width of 1.2 and 0.46 micrometer, respectively. it possessed a trilaminar cell wall with an adhering capsule-like layer. t ...	1979	570191
epidemiology and control of anaplasmosis in australia.	anaplasmosis occurs in those areas of northern and eastern australia infested by the cattle tick boophilus microplus but it has been studied intensively only in queensland. anaplasmosis is predominantly a disease of autumn and winter and of cattle greater than 1 year of age. the complement fixation test has been used in serological surveys of the tick-infested areas of the state. both clinical and subclinical infections occur only in tick-infested areas and they are both more frequent in bos tau ...	1979	553977

ehrlichiosis in wolves, dogs, and wolf-dog crosses.	canine ehrlichiosis was diagnosed in wolves, dogs, and wolf-dog crosses at a small zoo in northcentral florida. five of 9 adult canids and all 8 pups confined to a common kennel died as a result of the infection. the epizootic was associated with a massive rhipicephalus sanguineus infestation. hematologic and pathologic findings in an adult wolf-dog cross that died were characteristic of canine ehrlichiosis. that animal and four other canids were seropositive for ehrlichia canis. no deaths occur ...	1979	521367
