Louse-borne relapsing fever (LBRF) borreliosis is caused by Borrelia recurrentis, and it is a deadly although treatable disease that is endemic in the Horn of Africa but has epidemic potential. Research on LBRF has been severely hampered because successful infection with B. recurrentis has been achieved only in primates (i.e., not in other laboratory or domestic animals). Here, we present the f...
BACKGROUND In Africa, relapsing fever borreliae are neglected vector-borne pathogens that cause mild to deadly septicemia and miscarriage. Screening vectors for the presence of borreliae currently requires technically demanding, time- and resource-consuming molecular methods. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) has recently emerged as a to...
Ornithodoros turicata has been collected in Mexico and the United States. In the United States it is found in the states of Arizona, California, Colorado, Florida, Kansas, New Mexico, Oklahoma, Utah, and Texas. It is reported a vector of relapsing fever in Mexico, and in Kansas, New Mexico, Oklahoma, and Texas (Davis, 1942, Am. Assoc. Adv. Sci., 18, 67-76). In June, 1944, 121 Ornithodoros ticks...
Detecting spirochetes remains challenging in cases of African tick-borne relapsing fever. Using real-time PCR specific for the 16S rRNA Borrelia gene, we found 27 (13%) of 206 samples from febrile patients in rural Senegal to be positive, whereas thick blood smear examinations conducted at dispensaries identified only 4 (2%) as positive.
