| role of small mammals in the ecology of borrelia burgdorferi in a peri-urban park in north coastal california. | the role of small mammals other than woodrats in the enzootiology of the lyme disease spirochete, borrelia burgorferi, was assessed in the peri-urban park. mammals were collected monthly from september through to april. following tick removal, the animals were tested for b. burgdorferi by culture of ear-punch biopsies. larvae and nymphs that were intermediate in morphology between ixodes spinipalpis and ixodes neotomae occurred on several species of rodents (peromyscus truei, peromyscus californ ... | 1997 | 9291589 |
| rodent ectoparasites from two locations in northwestern florida. | from feb.-apr. 1999, 19 species of ectoparasitic arthropods (2 sucking lice, 4 fleas, 4 ticks, 2 mesostigmatid mites, 5 chiggers, 2 fur mites) were recovered from 106 rodents belonging to 5 species (cotton mouse, peromyscus gossypinus, n = 64; cotton rat, sigmodon hispidus, n = 23; eastern woodrat, neotoma floridana, n = 9; golden mouse, ochrotomys nuttalli, n = 9; eastern gray squirrel, sciurus carolinensis, n = 1) at tall timbers research station, leon county, florida. during the same period, ... | 2000 | 11217221 |
| host associations of ticks parasitizing rodents at borrelia burgdorferi enzootic sites in south carolina. | a total of 237 rodents was collected in 4 regions of south carolina from july 1994 through december 1995. eight species were collected, including cotton mouse, hispid cotton rat, eastern woodrat, marsh rice rat, white-footed mouse, eastern harvest mouse, golden mouse, and black rat. of the 1,514 ticks recovered from these hosts, ixodes minor neumann, including larvae, nymphs, and adults, was the most abundant species, representing 54% of the total. only immature stages of other tick species were ... | 2001 | 11780825 |
| prevalence of infection with francisella tularensis, borrelia burgdorferi sensu lato and anaplasma phagocytophilum in rodents from an endemic focus of tularemia in bulgaria. | the prevalence of francisella tularensis, borrelia burgdorferi and anaplasma phagocytophilum in rodents is a determinant for their role in maintaining pathogens in the environment. a total of 169 rodents, trapped in an endemic focus of tularemia, were examined by pcr to asses the frequency of infection with the etiological agents of tularemia, lyme borreliosis and human granulocytic anaplasmosis. the overall prevalence of f. tularensis was 22 %. in 6 % of the black rats, f. tularensis was identi ... | 2005 | 16028881 |
| ectoparasite diversity and exposure to vector-borne disease agents in wild rodents in central coastal california. | a survey of wild rodents was performed in the morro bay area of central coastal california to determine serological and polymerase chain reaction (pcr) prevalence of anaplasma phagocytophilum dumler, barbet, bekker, dasch, palmer, ray, rikihisa, and rurangirwa, borrelia burgdorferi johnson, schmidt, hyde, steigerwalt, and brenner, francisella tularensis mccoy, and yersinia pestis yersin; to describe the ectoparasitic fauna on important vector-borne disease hosts; and to determine whether pathoge ... | 2007 | 17427705 |
| remarkable diversity of tick or mammalian-associated borreliae in the metropolitan san francisco bay area, california. | the diversity of lyme disease (ld) and relapsing fever (rf)-group spirochetes in the metropolitan san francisco bay area in northern california is poorly understood. we tested ixodes pacificus, i. spinipalpis, and small mammals for presence of borreliae in alameda county in the eastern portion of san francisco bay between 2009 and 2012. analyses of 218 borrelia burgdorferi sensu lato (bb sl) culture or dna isolates recovered from host-seeking i. pacificus ticks revealed that the human pathogen b ... | 2014 | 25129859 |
| competence of urban rats as reservoir hosts for lyme disease spirochetes. | to determine whether urban rats serve efficiently as reservoir hosts for the agent of lyme disease, we recorded the frequency of infection in nymphal ixodes ricinus (l.) ticks that had fed as larvae on experimentally infected norway rats, rattus norvegicus (berkenhout), or on black rats, r. rattus (l.), and evaluated the nidicolous venue of transmission. subadult vector ticks attached readily to norway rats as well as black rats and virtually all became infected in the course of feeding. larval ... | 1997 | 9220684 |
| transmission of the agent of lyme disease on a subtropical island. | to determine whether the agent of lyme disease (borrelia burgdorferi) perpetuates on a subtropical island, we recorded prevalence of spirochetal infection in ixodes ricinus ticks collected on madeira island and identified local reservoir hosts of both pathogen and vector tick. spirochetes infect at least 1.3% of the nymphal ticks collected in a particular site. subadult ticks frequently parasitized norway as well as black rats on the island, and lyme disease spirochetes were found in these hosts ... | 1994 | 8066380 |
| interaction between acari ectoparasites and rodents in suez governorate, egypt. | from the medical point of view, the relation between man and rodents comes in the priority. some rodent populations are wild but others are commensal and live in close association with man. they steal his food and conveying many zoonotic diseases. their arthropod ectoparasites play an important role in conveying or transmitting these zoonotic diseases. several disorders and diseases of man are tick borne relapsing fever, rocky mountain spotted fever, lyme disease, and many others. besides numero ... | 1995 | 7665934 |
| prevalence of borrelia burgdorferi sensu lato in synanthropic rodents in two rural communities of yucatán, méxico. | lyme disease is a multisystemic zoonotic disease caused by borrelia burgdorferi sensu lato. this spirochete circulates in an enzootic cycle between the primary vertebrate reservoir and its tick vectors. different species of rodents are known to be efficient natural reservoirs for b. burgdorferi s.l. | 2016 | 27622631 |
