PHYSICIANS practising in Ireland will be surprised to find Ireland listed as a country subject to yellow fever in a comparatively recent publication. Carlos Finlay, ever to be remembered for his work on yellow fever, died in 1915, and in 1955 his medical school, Jefferson Medical College, held a commemorative conference on yellow fever. Doctor Pedro Nogueira (1955) reviewing the history and geo...

BACKGROUND Relapsing fever borreliae are vector-borne bacteria responsible for febrile infection in humans in North America, Africa, Asia, and in the Iberian Peninsula in Europe. Relapsing fever borreliae are phylogenetically closely related, yet they differ in pathogenicity and vectors. Their long-term taxonomy, based on geography and vector grouping, needs to be re-apprised in a genomic conte...

We describe a nested polymerase chain reaction for the identification of Borrelia species from serum of patients with unidentified fevers. This technique, based on single nucleotide polymorphisms of the 16S ribosomal RNA gene, was used to test blood samples from 7,750 patients, 33 of whom were diagnosed with spirochete infections. Borrelia crocidurae was the only species identified.

After the generalized famine fevers had come to an end in England they continued to scourge Ireland for centuries, where their course may be taken as a repetition of the happenings in England in earlier times. During the eighteenth century and part of the nineteenth, large numbers of the Irish peasantry. lived in a deplorable state of poverty; lacking reserves, one or two bad seasons might suff...

Serological response to louse-borne relapsing fever in Ethiopia was determined by immobilization tests using Borrelia recurrentis cultures. Isolates from 26 patients tested with autologous convalescent sera showed from 90 to 100% of the organisms had been immobilized. Sera from thirteen patients were tested with autologous and heterologous strains. Several reacted with the majority and two show...

Borrelia miyamotoi sensu lato, a relapsing fever Borrelia sp., is transmitted by the same ticks that transmit B. burgdorferi (the Lyme disease pathogen) and occurs in all Lyme disease-endemic areas of the United States. To determine the seroprevalence of IgG against B. miyamotoi sensu lato in the northeastern United States and assess whether serum from B. miyamotoi sensu lato-infected persons i...
