    Abstract Overconsumption of antibiotics in hospitals has led to policy implementation, including the control of antibiotic prescriptions. The impact of these policies on the evolution of antimicrobial resistance remains uncertain. In this work, we review the possible limits of such policies and focus on the need for a more efficient approach. Establishing a causal relationship between the introduction of new antibiotics and the emergence of new resistance mechanisms is difficult. Several studies have demonstrated that many resistance mechanisms existed before the discovery of antibiotics. Overconsumption of antibiotics has worsened the phenomenon of resistance. Antibiotics are responsible for intestinal dysbiosis, which is suspected of being the source of bacterial resistance. The complexity of the intestinal microbiota composition, the impact of the pharmacokinetic properties of antibiotics, and the multiplicity of other factors involved in the acquisition and emergence of multidrug-resistant organisms, lead us to think that de-escalation, in the absence of studies proving its effectiveness, is not the solution to limiting the spread of multidrug-resistant organisms. More studies are needed to clarify the ecological risk caused by different antibiotic classes. In the meantime, we need to concentrate our efforts on limiting antibiotic prescriptions to patients who really need it, and work on reducing the duration of these treatments.

    Abstract Burkholderia pseudomallei is a Gram-negative saprophytic bacillus that causes melioidosis. The infection is endemic in South-East of Asia and Northern Australia. B. pseudomallei has been designated as bioterrorism agent and its manipulation should be done in a biological safety level 3 capability. Workers in laboratories may be accidentally exposed to B. pseudomallei before its identification, with a risk of laboratory-acquired melioidosis. We want to describe a case of melioidosis occurred in our hospital and its management at laboratory. The objective of this article is to provide guidance to microbiologists confronted with a suspicious case of B. pseudomallei on the management of the exposition. We report here a couple of microbiological arguments that can usually guide microbiologists towards presumptive identification of B. pseudomallei. This case report shows the importance of MALDI-TOF MS accurate databases to ensure accurate microbial identification and antibiotic prophylaxis adapted to individuals who were exposed. We also want to underline the importance of developing an effective strategy of prevention against any accidental exposure that can occur in a microbiological laboratory.

    Abstract Pharmacological and clinical data regarding cefoxitin for the treatment of ESBL-producing Enterobacteriaceae-related infections are limited. We performed a multicentric prospective cohort study to evaluate continuous/prolonged, or intermittent infusion of cefoxitin. We assessed the plasma concentration as a function of the duration of infusion and then performed a simulation of the percentage of patients who would reach the PK/PD targets, set at 100% ƒT

    Abstract We aimed to assess the prevalence, risk factors, and visual outcome of Moraxella keratitis. We retrospectively reviewed the medical charts of patients diagnosed with Moraxella spp. keratitis at the Quinze-Vingts National Ophthalmology Hospital, Paris, France, between January 2016 and December 2018. Definitive microbiological identification was performed on archival strains using matrix-assisted laser desorption ionization time of flight coupled to mass spectrometry. One hundred one culture-proven cases of Moraxella keratitis were identified. The most common isolates were Moraxella lacunata (50%) and Moraxella nonliquefasciens (38%). Systemic predisposing factors, principally diabetes mellitus (13%) were identified in 28% of patients, and 87% of patients had ocular surface conditions, including blepharitis (25%), prior ocular surgery (21%), glaucoma (17%), exposure keratopathy (16%), and trauma (16%). Severely affected inpatients were treated empirically with fortified antibiotics including vancomycin, piperacillin, and gentamicin. The presence of hypopyon and being over the age of 60 years were associated with a poorer final visual acuity (p < 0.05). Adjuvant treatment, mostly amniotic membrane transplantation, was required for 31 eyes. The prognostic factors significantly associated with the need for adjuvant treatment were a larger infiltrate and hypoesthesia. The clinical features including ulcer healing, treatment duration, and infiltrate size were not different between Moraxella species. Keratitis caused by Moraxella spp. are rare in France but may threaten sight. The early identification of patients with a poor ocular surface, particularly those with neurotrophic keratopathy and anesthetic cornea, is crucial to prevent delayed healing of ulcers and the need for adjuvant treatment.

    Abstract In recent years, the diagnosis of bloodstream infections has been complemented by rapid microbiological methods, unattainable to most clinical laboratories in resource-limited settings. We evaluated the impact of their shortage on antibiotic therapy adequacy. We conducted a prospective multicenter cohort study including 150 adult Gram-negative bacilli bacteremia episodes, evenly distributed across three university hospitals: one in Lebanon, a resource-limited setting, and two in France, a resource-rich setting. Previous colonization by multidrug-resistant organisms (MDRO) was significantly more prevalent among the Lebanese than the French group of patients (16/50 vs. 5/100;

    Abstract Clostridium difficile is a major cause of healthcare-associated diarrhea. SlpA is the precursor of the S-layer of C. difficile. The aim of this work was to evaluate the humoral immune response of hospitalized patients to SlpA and its potential role on CDI outcome. Sera of 87 included patients were collected the day of CDI diagnosis as well as at early and late periods after infection. SlpA appeared to be immunogenic with a heterogeneous response between patients after a CDI. Patients with a single episode had a significantly higher anti-SlpA IgG antibody level than patients with recurrent CDI (p = 0.0197). These preliminary results will be useful to understand better the inter-individual variability of immune responses to C. difficile as well as for the development of new therapeutics.

    Abstract Babesiosis is a tick-borne infectious disease, caused by an intraerythrocytic parasite of the genus Babesia. It has clinical, biological and microbiological similarities with Plasmodium related infections. In rare cases, babesiosis may be complicated by hemophagocytic lymphohistiocytosis, which occurs preferentially in the immunodeficient patient. We report here the case of a non-immunocompromised patient living in Manhattan, New York hospitalized for a complicated babesiosis of a hemophagocytic lymphohistiocytosis. After 7 days of hospitalization and treatment by azithromycin 500 mg/day and atovaquone 750 mg twice a day, the patient was discharged with an improvement in clinical symptoms and biological parameters.

    Abstract This communication described how the Coris BioConcept COVID-19 Ag Respi-Strip test (Coris-Ag) was implemented in the workflow of our clinical microbiology laboratory for COVID-19 diagnosis. The diagnostic performance statistics (sensitivity, specificity) of the Coris-Ag were evaluated against a gold standard, the RealStar SARS-CoV-2 RT-PCR kit 1.0. Additionally, the effect of reading the Coris-Ag results at 30 min was compared to reading at 15 min. The Coris-Ag was performed on a total of 294 patients during two periods; 158 patients were tested during period 1 at the peak of the pandemic (April 6th to April 10th 2020) which returned a positivity rate of 17.1 %, and 136 patients during period 2 (April 12th to April 16th 2020) which returned a positivity rate of 11 %. Compared to the RT-PCR, the 15-minute Coris-Ag readings resulted in a sensitivity of 59.3 % with a 100 % specificity for the period 1 patients (n = 158) while the sensitivity decreased to 20 % for the period 2 patients (n = 136). The overall sensitivity was 38.1 % for both periods (n = 294). The corresponding 30-minute readings produced a 7 % increase in sensitivity with a specificity of 100 % (n = 294). The sensitivity of the strip test (15-min reading) for high viral loads (Ct <25) was 84.6 %.
