RESUMEN
INTRODUCTION: Cat scratch disease caused by Bartonella henselae with bone involvement is a rare presentation. CASE REPORT: We report a case of disseminated bartonellosis with multifocal osteomyelitis and multiple visceral involvement in an immunocompetent adult. Diagnostic confirmation was obtained by PCR on lymphadenopathy. In addition to our observation, 31 cases of bartonellosis with bone involvement were reported in the literature. Diagnosis is based on a combination of history, serology and PCR performed on tissue. The antibiotic treatment allows recovery in all cases. CONCLUSION: Cat scratch disease in its systemic form with bone involvement is a rare and difficult diagnosis for the clinician and an invasive approach is often required to obtain the diagnosis.

The Antemoro are an ethnic group from the southeast coast of Madagascar who claims an Arab origin. Cultural signatures of an Arabo-Islamic influence have been found in this region. Nevertheless, their origins are very contentious. Through this study, we want to determine whether this ethnic group had a particular GM profile that differentiated it from other Malagasy populations, and whether there were detectable genetic traces of the Arabo-Islamic migration. The Gm polymorphisms of IgG immunoglobulins was analysed in a population of Antemoro (N = 85), two other Malagasy populations from northern Fiherena (N = 82) and southern Fiherena (N = 50) and in a Comorian population (N = 171). This last group was used to enlarge the database for genetic comparisons. Results revealed significant contributions from Africa (60%, 0.092 ≤F(ST) ≤ 0.280) and Southeast Asia (40%, 0.043 ≤ F(ST) ≤ 0.590) to the Antemoro genetic pool. No direct genetic relationships with the Middle East. These results bring new insights into the population history of Madagascar.
