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 ...1975806533
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 ...1976814809
rickettsia-like organisms in ticks and antibodies to spotted fever-group rickettsiae in mammals from northern mississippi.studies were conducted from april through august during 1974 and 1975 on 30 randomly selected trapping sites in wall doxey state park, holly springs national forest, and 1.6 km south of the park in marshall county, mississippi to provide information on the occurrence of ticks involved in the maintenance and transmission of spotted fever-group rickettsiae in nature. of 365 animals (14 species) collected, 186 (51%) were parasitized by 4,169 ticks. species of ticks collected included: dermacentor v ...19853923212
babesiosis in the greyhound.babesiosis was diagnosed in five 11- to 18-day old greyhound pups. in 3 pups, babesia canis organisms were identified by examination of a wright's-giemsa-stained smear of blood. in 2 pups, the diagnosis was established by examination of a splenic impression smear obtained at necropsy. findings in the 3 clinical cases included depression, weakness, anorexia, pallor, anemia, and thrombocytopenia. subcutaneous administration of diminazene aceturate resulted in rapid clinical recovery in these cases ...19836853321
