ABSTRACT

OBJECTIVES: To describe the epidemiological, clinical, microbiological, and therapeutic characteristics of Nocardiosis patients treated in a general hospital. PATIENTS AND METHODS: Monocentric retrospective analysis of patients presenting with Nocardia-positive biological sample from January 1, 1998 to May 1, 2017. RESULTS: We identified nine cases of Nocardia infections. Risk factors were oral corticosteroid therapy (n=3), solid cancer (n=2), hematological cancer (n=1), COPD (n=1). No risk factor was identified in patients with isolated cutaneous presentation (n=2). Disseminated presentations (n=3) were observed in patients receiving corticosteroid therapy (n=2) and presenting with ENT cancer (n=1). Identified Nocardia species were Nocardia nova (n=4), Nocardia cyriacigeorgica (n=2), Nocardia abscessus (n=1), Nocardia brasiliensis (n=1), and Nocardia asteroides (n=1). The median diagnostic time was 17 days. Antibiotic therapy was prolonged and included trimethoprim-sulfamethoxazole in 6/9 cases. The overall one-year case fatality was high (3/8). No recurrence was observed. We identified two cases of respiratory colonization with N. abscessus and N. cyriacigeorgica in COPD patients. CONCLUSION: Nocardiosis can occur both in immunocompetent and immunocompromised patients. It is a severe infection, with a miscellaneous clinical spectrum and complex treatments. Greater knowledge of nocardiosis is required from physicians for optimal medical care.

ABSTRACT

OBJECTIVE: To collect data of all patients admitted to hospital with a positive test to Bordetella bronchiseptica between 2001 and 2015. METHODS: We performed a retrospective monocentric study of all hospitalized patients over the past 15 years with a positive test to B. bronchiseptica. RESULTS: Nine patients were included between 2001 and 2015; two presented with infectious relapses, i.e. a total of 14 positive test samples were observed. Age, induced immunodeficiency, and preexisting respiratory illnesses are risk factors. All patients showed symptoms at sample collection and the infection was exclusively respiratory. The diagnosis was obtained through a cytobacteriological test of sputum, bronchial aspiration, or bronchial fibroscopy with a bronchoalveolar lavage. The drug susceptibility test revealed a natural resistance to cephalosporins including ceftazidime, monobactam, and fosfomycin. There were cases of resistance to penicillin A and to the trimethoprim/sulfamethoxazole association. The classically used antibiotic treatment for community-acquired pneumonia is based on probability and may thus fail. Four patients died. The duration and nature of the antibiotics to use have not been codified. CONCLUSION: B. bronchiseptica infection mainly affects the elderly. All patients should be treated, regardless of the importance of the inoculum, and all infected animals should be treated.

ABSTRACT

Brucellosis is usually acquired by humans through contact with infected animals or the consumption of raw milk from infected ruminants. Brucella suis biovar 2 (BSB2) is mainly encountered in hares and wild boars (Sus scrofa), and is known to have very low pathogenicity to humans with only two case reports published in the literature. Human cases of brucellosis caused by BSB2 were identified through the national mandatory notification of brucellosis. The identification of the bacterium species and biovar were confirmed by the national reference laboratory. Epidemiological data were obtained during medical follow-up visits. Seven human cases were identified between 2004 and 2016, all confirmed by the isolation of BSB2 in clinical specimens. All patients had direct contact with wild boars while hunting or preparing wild boar meat for consumption. Five patients had chronic medical conditions possibly responsible for an increased risk of infection. Our findings suggest that BSB2 might be an emerging pathogen in hunters with massive exposure through the dressing of wild boar carcasses. Hunters, especially those with chronic medical conditions, should be informed about the risk of BSB2 infection and should receive information on protective measures.
