Detection of Bartonella spp. in fleas by MALDI-TOF MS
BACKGROUND Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) has recently emerged in the field of entomology as a promising method for the identification of arthropods and the detection of associated pathogens. METHODOLOGY/PRINCIPAL FINDINGS An experimental model of Ctenocephalides felis (cat fleas) infected with Bartonella quintana and Bartonella hen...
متن کاملBartonella infections in fleas (Siphonaptera: Pulicidae) and lack of bartonellae in ticks (Acari: Ixodidae) from Hungary.
Fleas (95 Pulex irritans, 50 Ctenocephalides felis, 45 Ctenocephalides canis) and ixodid ticks (223 ixodes ricinus, 231 Dermacentor reticulatus, 204 Haemaphysalis concinna) were collected in Hungary and tested, in assays based on PCR, for Bartonella infection. Low percentages of P. irritans (4.2%) and C. felis (4.0%) were found to be infected. The groEL sequences of the four isolates from P. ir...
متن کاملInfectious blood source alters early foregut infection and regurgitative transmission of Yersinia pestis by rodent fleas
Fleas can transmit Yersinia pestis by two mechanisms, early-phase transmission (EPT) and biofilm-dependent transmission (BDT). Transmission efficiency varies among flea species and the results from different studies have not always been consistent. One complicating variable is the species of rodent blood used for the infectious blood meal. To gain insight into the mechanism of EPT and the effec...
متن کاملBartonella rochalimae and Other Bartonella spp. in Fleas, Chile
the exact tissue type of each sample, only that tonsils, adenoids, or both combined could be present, the 5.5% rate we found was about one third the rate found in tonsil lymphocytes and about one tenth the rate found in adenoid lymphocytes. A seasonal effect may contribute to the large discrepancies found in HBoV prevalences. Apparently, viruses can persist in tonsillar tissue well after the sy...
متن کاملBartonella clarridgeiae in Fleas, Tahiti, French Polynesia
were conducted by using MEGA version 4.1 (www.megasoftware. net). The partial lppA gene nucleotide sequences of isolates GN407 and GN408 were submitted to GenBank under accession nos. HQ699892 and HQ699893, respectively. PCR amplifi cations of the 2 joint fl uids and their cultures were positive for M. leachii. When we compared the complete 16S rRNA gene and the partial lppA gene, the 2 isolate...
