| rickettsia felis rickettsiosis in yucatán. | three patients with fever, exanthem, headache, and central-nervous-system involvement were diagnosed with rickettsia fells infection by specific pcr of blood or skin and seroconversion to surrogate rickettsia antigens. although r. felis's relationship to other rickettsia species is known and the pathogenic potential of this clade is well documented, r. felis's role as a pathogen has not been fully understood. | 2000 | 11009147 |
| infection by rickettsia felis in opossums (didelphis sp.) from yucatan, mexico. | rickettsia felis is an emergent pathogen and the causative agent of a typhus-like rickettsiosis in the americas. its transmission cycle involves fleas as biological vectors (mainly ctenocephalides felis) and multiple domestic and synanthropic mammal hosts. nonetheless, the role of mammals in the cycle of r. felis is not well understood and many efforts are ongoing in different countries of america to clarify it. the present study describes for the first time in mexico the infection of two specie ... | 2016 | 27074326 |
| rickettsia rickettsii and rickettsia felis infection in rhipicephalus sanguineus ticks and ctenocephalides felis fleas co-existing in a small city in yucatan, mexico. | | 2015 | 26611982 |
| severe human infection with rickettsia felis associated with hepatitis in yucatan, mexico. | rickettsia felis infection usually is a mild-to-moderate illness characterized by general signs and symptoms. generally, patients do not require hospitalization. however, we detected 2 severe infections with r. felis. our findings support the importance of r. felis infection as a potentially severe illness in humans. | 2009 | 19481502 |
| rickettsia felis, the agent of an emerging infectious disease: report of a new case in mexico. | the fourth case of human infection with rickettsia felis in yucatán, mexico was documented by serologic testing and polymerase chain reaction (pcr). the role of r. felis in human disease has been demonstrated by molecular methods in a few patients from the u.s., yucatán, brazil and germany. apparently, there is a wide spectrum in the clinical presentation of the worldwide reported cases. | 2006 | 16513497 |
| detection of rickettsia felis in wild mammals from three municipalities in yucatan, mexico. | the aim of this study was to provide information of the occurrence of rickettsia felis in wild mammals from three municipalities in yucatan, mexico. the reactivity of rodent serum to rickettsia antigens was detected in 80.9% (17 of 21) samples using immunofluorescence assay. polymerase chain reaction identified rickettsial dna in spleens of 43.5% (10 of 23) rodents and 57.1% (4 of 7) opossums. the identification of the rickettsial dna was confirmed as r. felis by restriction fragment length poly ... | 2015 | 25537628 |
| identification of ctenocephalides felis fleas as a host of rickettsia felis, the agent of a spotted fever rickettsiosis in yucatań, mexico. | in search for the vector of the recently recognized spotted fever rickettsiosis of the yucatán, ticks, fleas, and lice were collected from vegetation and dogs in localities where seropositive persons had been found. the arthropods were examined by polymerase chain reaction (pcr) using primers for the genus-specific 17-kda protein gene followed by restriction fragment length polymorphism (rflp) and dna sequencing. eleven (20%) of 54 pools of ctenocephalides felis fleas contained dna of rickettsia ... | 2002 | 12653300 |
