| molecular detection of rickettsia felis in different flea species from caldas, colombia. | rickettsioses caused by rickettsia felis are an emergent global threat. historically, the northern region of the province of caldas in colombia has reported murine typhus cases, and recently, serological studies confirmed high seroprevalence for both r. felis and r. typhi. in the present study, fleas from seven municipalities were collected from dogs, cats, and mice. dna was extracted and amplified by polymerase chain reaction (pcr) to identify glta, ompb, and 17kd genes. positive samples were s ... | 2013 | 23878183 |
| detection of rickettsia felis, rickettsia typhi, bartonella species and yersinia pestis in fleas (siphonaptera) from africa. | little is known about the presence/absence and prevalence of rickettsia spp, bartonella spp. and yersinia pestis in domestic and urban flea populations in tropical and subtropical african countries. | 2014 | 25299702 |
| fleas and ticks in carnivores from a domestic-wildlife interface: implications for public health and wildlife. | fleas and ticks are parasites of wild and domestic mammals, and can be vectors of several pathogens. in rural areas, domestic carnivores such as the domestic dog (canis lupus familiaris l.), may act as a "bridge" between natural areas and human settlements where ectoparasites can be used as a metric of such link. the aim of this study was to identify fleas, ticks, and rickettsia spp., collected from domestic and wild carnivores in a natural reserve and surrounding human settlements in central ch ... | 2016 | 27539151 |
| molecular and serological evidence of flea-associated typhus group and spotted fever group rickettsial infections in madagascar. | rickettsiae are obligate intracellular bacteria responsible for many febrile syndromes around the world, including in sub-saharan africa. vectors of these pathogens include ticks, lice, mites and fleas. in order to assess exposure to flea-associated rickettsia species in madagascar, human and small mammal samples from an urban and a rural area, and their associated fleas were tested. | 2017 | 28259176 |
| molecular detection of rickettsia felis and bartonella henselae in dog and cat fleas in central oromia, ethiopia. | fleas are important vectors of several rickettsia and bartonella spp. that cause emerging zoonotic diseases worldwide. in this study, 303 fleas collected from domestic dogs and cats in ethiopia and identified morphologically as ctenocephalides felis felis, c. canis, pulex irritans, and echidnophaga gallinacea were tested for rickettsia and bartonella dna by using molecular methods. rickettsia felis was detected in 21% of fleas, primarily c. felis, with a similar prevalence in fleas from dogs and ... | 2014 | 24445204 |
| molecular detection of rickettsia felis and candidatus rickettsia asemboensis in fleas from human habitats, asembo, kenya. | the flea-borne rickettsioses murine typhus (rickettsia typhi) and flea-borne spotted fever (fbsf) (rickettsia felis) are febrile diseases distributed among humans worldwide. murine typhus has been known to be endemic to kenya since the 1950s, but fbsf was only recently documented in northeastern (2010) and western (2012) kenya. to characterize the potential exposure of humans in kenya to flea-borne rickettsioses, a total of 330 fleas (134 pools) including 5 species (xenopsylla cheopis, ctenoceph ... | 2013 | 23675818 |
| incidence and distribution pattern of rickettsia felis in peridomestic fleas from andalusia, southeast spain. | the presence of rickettsia felis was investigated in three species of pulicid fleas (ctenocephalides felis, ctenocephalides canis and pulex irritans) collected in 38 locales in andalusia (spain) over the period 1999-2004. amplification of a fragment of ompb gene was positive in 54.17 % of lots of ct. felis. the identity of the pcr bands was confirmed as r. felis by sequence data obtained directly from the pcr amplicon. no rickettsia was found in ct. canis nor p. irritans. | 2006 | 17114737 |
| arthropod-borne diseases in homeless. | homeless people are particularly exposed to ectoparasite. the living conditions and the crowded shelters provide ideal conditions for the spread of lice, fleas, ticks, and mites. body lice have long been recognized as human parasites and although typically prevalent in rural communities in upland areas of countries close to the equator, it is now increasingly encountered in developed countries especially in homeless people or inner city economically deprived population. fleas are widespread but ... | 2006 | 17114713 |
| bartonella quintana and rickettsia felis in gabon. | we detected rickettsia felis dna in ctenocephalides felis and bartonella quintana dna in 3 pulex irritans fleas taken from a pet cercopithecus cephus monkey in gabon, sub-saharan africa. this is the first report of b. quintana in the human flea. | 2005 | 16318727 |
| 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 ... | 2017 | 28399271 |
| first detection of rickettsia typhi and rickettsia felis in fleas collected from client-owned companion animals in the southern great plains. | flea-borne rickettsiosis occurs worldwide and includes a number of pathogens, namely, rickettsia typhi and rickettsia felis. most studies in the united states have occurred in southern texas and california where flea-borne rickettsiosis is endemic, resulting in a lack of information from other regions of the country. between march and august 2016, 222 fleas were collected from 52 client-owned dogs and cats in two urban areas in oklahoma. fleas were identified using morphological characteristics ... | 2017 | 28399210 |
