Purulent pleurisy caused by Campylobacter lari

Cellulitis with persistent bacteremia caused by Campylobacter lari in a patient with mantle-cell lymphoma

Campylobacter lari is an organism occasionally isolated in humans but rarely causes bacteremia. We report the first case of cellulitis with bacteremia due to C. lari in a patient undergoing mantle-cell lymphoma. A 51-year-old man presented with a two-month history of fever and bilateral leg pain and redness. Despite oral ciprofloxacin administration, his symptoms had not improved. The blood culture sample in the anaerobic bottle yielded positive results and C. lari was identified by mass spectrometry. The bacteremia did not initially respond to oral azithromycin but responded to intravenous meropenem and amikacin for five days followed by oral minocycline. This report indicates that C. lari bacteremia may be treated with oral minocycline following short-term intravenous antimicrobial therapy even among patients undergoing hematological malignancies.

Fatal relapse of a purulent pleurisy caused by Campylobacter fetus subsp. fetus

Campylobacter fetus is associated with invasive disease, while other Campylobacter species, such as C. coli and C. jejuni, are a common cause of bacterial diarrhea. Bacteremia has been well described, but pleurisy remains very uncommon. We report the recurrent isolation of a C. fetus subsp. fetus strain during two episodes of pleural effusion with a fatal outcome.

Fatal case of Campylobacter lari prosthetic joint infection and bacteremia in an immunocompetent patient

Campylobacter lari is an infrequent cause of intestinal and extraintestinal infection in humans. We report a case of C. lari prosthetic joint infection and bacteremia in an 81-year-old immunocompetent man. The infection was associated with septic shock and fatal outcome. C. lari may cause severe disease, even in an immunocompetent host.
