high prevalence of rickettsia spp. in dog fleas (siphonaptera: pulicidae) in rural uganda.fleas are known vectors of zoonotic agents. thirty-five fleas, including 28 ctenocephalides felis (bouché), four pulex irritans (l.), and three echidnophaga gallinacea (westwood) from 19 rural dogs from southwestern uganda were analyzed for the presence of rickettsia spp. (ompb, glta, and 17 kda fragment genes) and bartonella spp. (rpob and its genes) by pcr. rickettsial dna was detected in 27 out of 28 of ct. felis and in two out of four p. irritans. none of the e. gallinacea specimens harbored ...201728399271
potential roles of pigs, small ruminants, rodents, and their flea vectors in plague epidemiology in sinda district, eastern zambia.a cross-sectional study was conducted in the eastern part of zambia that previously reported a plague outbreak. the aim of the study was to evaluate the potential role of pigs, goats, and sheep as sero-surveillance hosts for monitoring plague, and to investigate the flea vectors and potential reservoir hosts to establish the current status of plague endemicity in the district. serum samples were collected from 96 rodents, 10 shrews, 245 domestic pigs, 232 goats, and 31 sheep, whereas 106 organs ...201728399281
prevalence and seasonality of fleas associated with california ground squirrels and the potential risk of tularemia in an outdoor non-human primate research facility.ectoparasites at primate research centers may be difficult to control, e.g. without exposing non-human primates (nhps) to toxicants, but their impact on nhp health is poorly understood. in 2010, there was an epizootic of tularemia at the california national primate research center (cnprc) in yolo county, california that resulted in 20 confirmed and suspect clinical cases in outdoors housed rhesus macaques (macaca mulatta [zimmermann]) and a 53% seroprevalence in the southern section of the colon ...201729202201
fleas of small mammals on reunion island: diversity, distribution and epidemiological consequences.the diversity and geographical distribution of fleas parasitizing small mammals have been poorly investigated on indian ocean islands with the exception of madagascar where endemic plague has stimulated extensive research on these arthropod vectors. in the context of an emerging flea-borne murine typhus outbreak that occurred recently in reunion island, we explored fleas' diversity, distribution and host specificity on reunion island. small mammal hosts belonging to five introduced species were ...201425188026
what's eating you? sticktight flea revisited.the sticktight flea (echidnophaga gallinacea) earns its name by embedding its head in the host's skin. it has been found in many species of birds and mammals, including humans. the sticktight flea is found worldwide in the tropics, subtropics, and temperate zones, and it is the only representative of this genus found in the united states. bites from fleas cause irritation and itching for hosts including humans, typically resulting in clusters of firm, pruritic, erythematous papules. treatment ca ...201728873107
