AFLP analysis using a selective primer delineated five profiles that correlated well with those obtained by sequence comparison. Combination of all three data sets divided the isolates into six genotypes. One of these genotypes was common to isolates collected from a large area in western Peru that corresponded to the region of endemicity for bartonellosis; however, isolates belonging to two other genotypes were also found within this region. Two of these genotypes were found in isolates isolated more than 35 years apart. The remaining three genotypes were each specifically associated with three outbreaks of bartonellosis that have recently occurred in areas where the disease had not previously been recognized. Demonstration of the unique nature of these isolates indicates that the outbreaks with which they were associated did not result from the introduction of disease by individuals who acquired their infection in the recognized region of endemicity. The sources of these outbreaks remain unknown. A consensus approach to bacterial typing using comparative sequence analysis of multiple genetic loci and the pan-genomic sampling of AFLP appears to offer a well-supported assessment of\n            <jats:italic>B. bacilliformis<\/jats:italic>\n            diversity, and the genotypic differences identified appear to have epidemiological significance.\n          <\/jats:p>","DOI":"10.1128\/jcm.40.10.3606-3612.2002","type":"journal-article","created":{"date-parts":[[2002,9,28]],"date-time":"2002-09-28T00:04:10Z","timestamp":1033171450000},"page":"3606-3612","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":29,"title":["Identification of\n            <i>Bartonella bacilliformis<\/i>\n            Genotypes and Their Relevance to Epidemiological Investigations of Human Bartonellosis"],"prefix":"10.1128","volume":"40","author":[{"given":"Richard J.","family":"Birtles","sequence":"first","affiliation":[{"name":"Department of Veterinary Pathology, Faculty of Veterinary Sciences, University of Liverpool, Neston, Cheshire CH64 7TE"},{"name":"Unite\u0301 des Rickettsies, Faculte\u0301 de Me\u0301decine, 13385 Marseille, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norman K.","family":"Fry","sequence":"additional","affiliation":[{"name":"Respiratory and Systemic Infection Laboratory, Public Health Laboratory Service, Central Public Health Laboratory, London NW9 5HT, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Palmira","family":"Ventosilla","sequence":"additional","affiliation":[{"name":"Instituto de Medicina Tropical Alexander Von Humboldt, Universidad Peruana Cayetano Heredia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abraham G.","family":"Ca\u0301ceres","sequence":"additional","affiliation":[{"name":"Instituto de Medecina Tropical Daniel A.
