ABSTRACT
Diphyllobothriasis is caused in humans by infection with adult tapeworms of the genus Diphyllobothrium acquired by consuming raw or undercooked freshwater fish. Diphyllobothrium latum was confirmed by examination of the gravid proglottids and typical operculated eggs in the stool. The patient had a history of eating crustaceans and fish. This is the case report of the first Brazilian infected.

Difilobotriose é causada em humanos pela infeccão com vermes adultos do gênero Diphyllobothrium adquiridos pelo consumo de peixe cru ou mal cozido. Diphyllobothrium latum foi confirmado pelo exame dos proglotes grávidos e típicos ovos operculados nas fezes. O paciente havia comido crustáceos e peixes. É o relato do primeiro brasileiro infectado.

Anaerobiospirillum succiniciproducens is an anaerobic, Gram-negative, spiral shaped bacteria, which is motile by means of bipolar tuffs of flagella. This organism appears to be a rare cause of bacteremia in humans, and it usually affects patients submitted to immunosuppressive therapy. Anaerobiospirillum succiniciproducens resembles Campylobacter spp. in Gram-stained preparations, however, it is considered resistant to most antimicrobial drugs that are used to treat Campylobacter infections. We observed Gram-negative, spiral shaped bacteria in Gram-stained preparations from blood culture flasks. Growth occurred only under anaerobic incubation, and identification to the species level was achieved by PCR amplification of the 16S rRNA gene, followed by direct sequencing and a GenBank homology search. To the best of our knowledge, this is the first reported Brazilian case of Anaerobiospirillum succiniciproducens bacteremia.
