Abstract
Although a high prevalence of COVID-19-associated pulmonary aspergillosis has been reported, it is still difficult to distinguish between colonization with Aspergillus fumigatus and infection. Concomitantly, similarities between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and hypersensitivity pneumonitis were suggested. The objective of this study was to investigate retrospectively if precipitin assays targeting A. fumigatus could have been useful in the management of SARS-CoV-2 patients hospitalized in an Intensive Care Unit (ICU) in 2020. SARS-CoV-2 ICU patients were screened for Aspergillus co-infection using biomarkers (galactomannan antigen, qPCR) and culture of respiratory samples (tracheal aspirates and bronchoalveolar lavage). For all these patients, clinical data, ICU characteristics and microbial results were collected. Electrosyneresis assays were performed using commercial A. fumigatus somatic and metabolic antigens. ELISA were performed using in-house A. fumigatus purified antigen and recombinant antigens. Our study population consisted of 65 predominantly male patients, with a median ICU stay of 22 days, and a global survival rate of 62%. Thirty-five patients had at least one positive marker for Aspergillus species detection. The number of arcs obtained by electrosyneresis using the somatic A. fumigatus antigen was significantly higher for these 35 SARS-CoV-2 ICU patients (P 0.01, Welch's t-test). Our study showed that SARS-CoV-2 ICU patients with a positive marker for Aspergillus species detection more often presented precipitins towards A. fumigatus. Serology assays could be an additional tool to assess the clinical relevance of the Aspergillus species in respiratory samples of SARS-CoV-2 ICU patients.

Abstract
Interlaboratory evaluations of Mucorales qPCR assays were developed to assess the reproducibility and performance of methods currently used. The participants comprised 12 laboratories from French university hospitals (nine of them participating in the Modimucor study) and 11 laboratories participating in the Fungal PCR Initiative. For panel 1, three sera were each spiked with DNA from three different species (Rhizomucor pusillus, Lichtheimia corymbifera, Rhizopus oryzae). For panel 2, six sera with three concentrations of R. pusillus and L. corymbifera (1, 10, and 100 genomes/ml) were prepared. Each panel included a blind negative-control serum. A form was distributed with each panel to collect results and required technical information, including DNA extraction method, sample volume used, DNA elution volume, qPCR method, qPCR template input volume, qPCR total reaction volume, qPCR platform, and qPCR reagents used. For panel 1, assessing 18 different protocols, qualitative results (positive or negative) were correct in 97% of cases (70/72). A very low interlaboratory variability in Cq values (SD = 1.89 cycles) were observed. For panel 2 assessing 26 different protocols, the detection rates were high (77-100%) for 5/6 of spiked serum. There was a significant association between the qPCR platform and performance. However, certain technical steps and optimal combinations of factors may also impact performance. The good reproducibility and performance demonstrated in this study support the use of Mucorales qPCR as part of the diagnostic strategy for mucormycosis.

Abstract
Hypersensitivity pneumonitis (HP) is a chronic inflammatory lung disease caused by repeated inhalation of antigenic substances. We present a case of metalworking fluids (MWFs)-HP sensitized to Pseudomonas oleovorans in a cystic fibrosis patient. This case illustrates that HP diagnosis remains challenging, especially in patients with another pulmonary disease, and that serodiagnosis contributes to identifying the precise microorganism involved. It also demonstrates that P. oleovorans is an important secondary aetiological agent in MWF-HP, less known than Mycobacterium immunogenum.

Abstract
PURPOSE Penicillium is the most common mould isolated in housing. Penicillium chrysogenum is the only species tested by prick test or serology for allergic patients. The American Institute of Medicine has accepted Penicillium as an aetiological agent of rhinitis in children and adults and as an asthma agent in children. However, few studies have identified Penicillium in housing to the species level (354 species). Phenotypic identification is difficult. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) should be an alternative. The aim of this study was (1) to identify the Penicillium species present in dwellings in Eastern France and (2) to evaluate the reliability of MALDI-TOF MS for identification, by comparing it to DNA sequencing and phenotypic identification. METHODOLOGY Identification to the species level was performed by MALDI-TOF MS on 275 strains isolated from 48 dwellings. These results were compared to beta-tubulin gene sequencing and to the phenotypic aspects. RESULTS Thanks to MALDI-TOF, 235/275 strains could be identified (85.5 %). Fourteen species were identified among 23 Penicillium species included in the Filamentous Fungi Library 1.0 (Bruker Daltonics). However, 72.2 % of the strains belonged to five main taxa: P. chrysogenum (27.3 %), Penicillium glabrum (22.9 %), Penicilliumcommune (11.3 %), Penicillium brevicompactum (6.5 %) and Penicillium expansum (4.2 %). CONCLUSION Complete coherence between MALDI-TOF MS and sequence-based identification was found for P. chrysogenum, P. expansum, P. glabrum, Penicillium italicum and Penicillium corylophilum. The main drawback was observed for Penicillium crustosum, which included 21 strains (7.6 %) that could not be identified using MALDI-TOF MS.

Abstract
BACKGROUND Cutaneous mucormycoses, mainly due to Lichtheimia (Absidia), have occurred on several occasions in the Burn Unit of the University Hospital of Lille, France. AIM To investigate the potential vector role of non-sterile bandages used to hold in place sterile gauze used for wound dressing. METHODS Mycological analysis by conventional culture, Mucorales real-time polymerase chain reaction (qPCR), and Lichtheimia species-specific qPCR were performed on eight crepe and six elasticized bandages that were sampled on two independent occasions in March 2014 and July 2016. Characteristics of the seven Lichtheimia mucormycoses which occurred in burn patients between November 2013 and July 2016 were also collected to assess the epidemiological relationship between potentially contaminated bandages and clinical infections. FINDINGS One Lichtheimia corymbifera strain was isolated from a crepe bandage by culture, and Lichtheimia spp. qPCR was positive in six out of eight crepe and four out of six elasticized bandages. Using species-specific qPCR, Lichtheimia ramosa, Lichtheimia ornata, and L. corymbifera were identified in six out of ten, five out of ten, and four out of ten bandages, respectively. In patients with mucormycosis, L. ramosa and L. ornata were present in five and two cases, respectively. CONCLUSION Our data support the utility of Mucorales qPCR for epidemiological investigations, the potential role of these bandages in cutaneous mucormycoses in burn patients in our centre, and, consequently, the need for sterile bandages for the dressing of extensive wounds.

Abstract
The aim of this work was to perform a thorough analysis of the diversity of Y-haplotypes in Spanish cattle. A total of 207 Bos taurus males were sampled across 25 European breeds, with a special focus on rare, local Spanish populations. Animals were genotyped with five Y-specific microsatellites (INRA189, UMN0103, UMN0307, BM861 and BYM1), two indels (ZFY10 and USP9Y) and one SNP (UTY19). A new haplogroup, distinct from those described by Götherström et al. (2005), was identified and named Y1.2. Samples representing the three B. taurus Y-haplogroups were genotyped for four additional Y chromosome SNPs (rs121919254, rs121919281, rs121919323 and rs137049553). Among these SNPs, only rs121919281 was informative in B. taurus and helped to confirm the new Y1.2 haplogroup. Analysis of a larger dataset of standardized haplotypes for 1507 individuals from 57 populations from Spain, other European countries and Africa showed the new Y1.2 haplogroup to be found exclusively in Spanish breeds. This finding reinforces the importance of local Spanish cattle as reservoirs of genetic diversity as well as the importance of the Iberian Peninsula in the history of cattle.

Abstract
Recycling of organic waste appeals to more and more people. The aim of this study was to evaluate the microbiological contamination around organic waste bins at three distances over a 12-month period. Contamination near the customary trash of control households was evaluated at the beginning to ensure that there is no recruitment bias. Air samples using the MAS 100 impactor were carried out in 38 dwellings that do household waste composting and in 10 dwellings of controls. Collection of particles by CIP 10 rotating cup sampler and dust samples collected by electrostatic dust collector cloths were acquired in dwellings that do household waste composting. Samples were analyzed by culture and by real-time quantitative PCR. Information about dwelling characteristics and inhabitant practices was obtained by a standardized questionnaire. The genera most often isolated were Penicillium, Aspergillus, Cladosporium and Streptomyces. Near the organic waste bins, bioaerosol samples showed an increase of Acarus siro (P = 0.001). Sedimented dust analyses highlighted an increase of A. siro, Wallemia sebi, Aspergillus versicolor, and Cladosporium sphaerospermum concentrations after a 12-month survey compared to the beginning. Composting favors microorganism development over time, but does not seem to have an effect on the bioaerosol levels and the surface microbiota beyond 0.5 m from the waste bin.

Abstract
The main objective of this study was to assess the diagnostic performance of a set of three Mucorales quantitative PCR assays in a retrospective multicentre study. Mucormycosis cases were recorded thanks to the French prospective surveillance programme (RESSIF network). The day of sampling of the first histological or mycological positive specimen was defined as day 0 (D0). Detection of circulating DNA was performed on frozen serum samples collected from D-30 to D30, using quantitative PCR assays targeting Rhizomucor, Lichtheimia, Mucor/Rhizopus. Forty-four patients diagnosed with probable (n = 19) or proven (n = 25) mucormycosis were included. Thirty-six of the 44 patients (81%) had at least one PCR-positive serum. The first PCR-positive sample was observed 9 days (range 0-28 days) before diagnosis was made using mycological criteria and at least 2 days (range 0-24 days) before imaging. The identifications provided with the quantitative PCR assays were all concordant with culture and/or PCR-based identification of the causal species. Survival rate at D84 was significantly higher for patients with an initially positive PCR that became negative after treatment initiation than for patients whose PCR remained positive (48% and 4%, respectively; p <10-6). The median time for complete negativity of PCR was 7 days (range 3-19 days) after initiation of l-AmB treatment. Despite some limitations due to the retrospective design of the study, we showed that Mucorales quantitative PCR could not only confirm the mucormycosis diagnosis when other mycological arguments were present but could also anticipate this diagnosis. Quantification of DNA loads may also be a useful adjunct to treatment monitoring.

Abstract
Azole resistant Aspergillus fumigatus strains are increasingly reported in many countries. One resistance mechanism is attributed to the use of azole fungicides in environment. Two mutations, TR34/L98H and TR46/Y121F/T289A, on the cyp51A gene, have been described. Results of 40 publications about azole resistant strain detections, with TR34/L98H and TR46/Y121F/T289A mutations, in clinical and/or environmental samples, are presented in this review. These cases, observed in many countries, suggest spreading phenomenon. Measures to moderate fungicides treatments and/or alternative treatments in environment should be established to preserve the effectiveness of azole antifungal therapy for at-risk patients.

Abstract
Although exposure to indoor microorganisms in early life has already been associated with respiratory illness or allergy protection, only a few studies have performed standardized samplings and specific microbial analysis. Moreover, most do not target the different groups of microorganisms involved in respiratory diseases (fungi, bacteria, dust mites). In our study, ten specific qPCR targets (6 fungal species, 1 family and 2 genera of bacteria, 1 house dust mite) were used to analyze the microorganism composition of electrostatic dust fall collector (EDC) from 3193 dwellings of the Elfe French cohort study. Multivariate analyses allowed us to show that the microbial composition of dwellings, assessed with simultaneous analysis of 10 microorganisms, can be characterized by four entities: three bacteria, house dust mite Dermatophagoïdes pteronyssinus, fungi Alternaria alternata, and five other molds. Some dwellings' intrinsic characteristics (occupational ratio, type of dwelling and presence of pets) clearly influence microorganism distribution, and six different profiles of dwellings, characterized by their composition in microorganisms, have been described across France. The use of these clusters seems promising in the evaluation of allergic risk. Allergic respiratory diseases will develop in the near future in some children of the Elfe cohort and will indicate to what extent our approach can be predictive of respiratory disease.

Abstract
UNLABELLED Contrary to hospital exposure, little is known about the indoor fungal exposure of hematology patients at home. The aim of our study was to investigate the mold exposure of hematology patients both at home and at hospital to assess their invasive aspergillosis (IA) risk. Fungal exposure was assessed by quantifying opportunistic molds at hospital during hospitalization and in homes of 53 hematology patients. IA was diagnosed in 13 of 53 patients and invasive fungal infection (IFI) in one patient. In hospital, no opportunistic species, or low levels of opportunistic species, were found in 98% of weekly controls. Only 2% of hematology intensive care unit (ICU) controls showed a high level of Aspergillus fumigatus spores in corridor air. Five patients IA were hospitalized during these periods. Seven dwellings of 53 (5/14 dwellings of patients with IA/IFI and 2/39 dwellings of non-IA patients) had a percentage of A. fumigatus and Aspergillus flavus to total mold (significant predictor variable of IA/IFI in our study, general linear model, P-value = 0.02) as high as 15%. Maintaining a 'zero Aspergillus' goal at hospital is essential, and establishing specific and individually opportunistic mold monitoring at home could help to further reduce the IA risk through continuous surveillance. PRACTICAL IMPLICATIONS This study emphasizes the fact that preventive measures should not be aimed only at the hospital setting: among patients diagnosed with invasive aspergillosis/invasive fungal infection (IA/IFI), 5 of 14 (36%) were exposed to opportunistic fungal species at home exclusively. Moreover, four of these five patients were living in homes having the highest percentage of Aspergillus fumigatus and Aspergillus flavus (>15%), one of which had 48% of A. fumigatus. Therefore, our work supports the need for a counselor to carry out an environmental survey in patients’ homes.

Abstract
OBJECTIVE To evaluate the level of microbial contamination of general pratice environment. METHODS Ten points, including air, water and surfaces were sampled in general practitioner's consultation room of 30 general practices in Franche-Comté region (eastern France). For each sample, a global microbial count was assessed as well as the presence of potential pathogen microorganisms: Aspergillus fumigatus, Staphylococcus aureus, Pseudomonas aeruginosa, and Enterobacteriaceae. RESULTS We note that 66.3% of the samples (n=202) were on the target level (<51 ufc/25 cm (2), <101 ufc/m(3), <100 ufc/mL in total bacteria, without pathogenic species and without A. fumigatus respectively on surfaces, air and water, without isolation of coliforme bacteria or P. aeruginosa for 100mL of water). A. fumigatus, S. aureus, P. aeruginosa and Enterobacteriaceae were recovered in 8.0%, 2.1%, 0.7%, 0% respectively. However, 66.7% of air sampling were positive to A. fumigatus with 2 to 12 cfu/m(3). CONCLUSION This study shows a low level of bacterial contamination of general practitioner's consultation room. A. fumigatus frequency in air samples seems equivalent to that found in housing without air treatment.

Abstract
UNLABELLED Fungi that damage documents in archives may harm workers' health, depending on which mold species are inhaled, the concentrations of fungal species inhaled, and individual factors. Our aim was to identify and quantify fungi in archives and to investigate possible links with the symptoms experienced by workers. Ten French archives were sampled using an air impactor and electrostatic dust collectors. Allergies and general symptoms felt by 144 workers were reported using a self-report questionnaire. Utilizing culture-based analysis methods along with qPCR, Penicillium chrysogenum, Cladosporium sphaerospermum, and Aspergillus versicolor were the three main fungi in air and dust in terms of quantity and frequency. Median fungal concentrations in storage areas, ranged from 30 to 465 CFU/m(3). People working in the most contaminated archives did not report more symptoms of allergy than others. However, workers in contact with moldy documents reported more headaches (odds ratio, 2.4; 95% confidence interval, 1.1-5.3), fatigue (OR, 2.9; 95% CI, 1.2-6.7), eye irritation (OR, 5.4; 95% CI, 1.9-14.9), throat irritation (OR, 2.4; 95% CI, 1.0-5.7), coughing (OR, 3.2; 95% CI, 1.2-8.4), and rhinorrhea (OR, 2.6; 95% CI, 1.0-6.4) than others. Other parameters such as dust levels and concentrations of metabolites and chemical substances should be considered as confounding factors in further investigations to isolate the role of molds. PRACTICAL IMPLICATIONS Most studies about fungi and archives deal with the conservation of manuscripts and documents, and few discuss workers' health problems. Our study shows that archives do not represent a highly contaminated environment. Symptoms felt by workers were more often linked to direct contact with moldy documents than to high concentrations of mold in the air of archive storage areas. This study provides data on concentration levels in archives that could be used to interpret microbiological investigations in this type of environment in the future.

Abstract
Several studies have suggested that children exposed to a farm environment are protected against allergies and asthma. The present work is an environmental study nested within the PASTURE cohort and includes 97 farmers and 74 non-farmers in three regions of the Alpine Arc (Switzerland, France and Germany). The objectives were to determine and compare the fungi and actinomycetes present in farming and non-farming environments (children's bedrooms and cowsheds), and to identify the agricultural practices associated with an increase in airborne fungi and actinomycetes in cowsheds. Air samples were collected by air pump and were analysed by culture and by direct counting of spores on membranes. During their stay in bedrooms, children living on farms were exposed to significantly greater amounts of Absidia spp., Eurotium spp., Cladosporium spp., Penicillium spp. and mesophilic actinomycetes than children who did not live on farms. Depending on the season, the levels of moulds, yeasts and actinomycetes were from 14 to 82 times higher in cowsheds before feeding the cattle than in children's bedrooms, and from 12 to 464 times higher in cowsheds after feeding than in children's bedrooms. Feeding cattle in cowsheds was associated with a significant peak in airborne moulds and actinomycetes, and this peak was higher in winter than in summer. Silage distribution was associated with low amounts of moulds and actinomycetes. Other significant agricultural factors were the type of cowshed, cowshed volume, method of food distribution to cattle and use of fresh grass. An assessment of the microbiological diversity on farms and in children's rooms may help to determine the factors protecting children from asthma and atopic diseases.

Abstract
Metalworking fluids (MWF) are responsible for hypersensitivity pneumonitis (HP). The aim of the present study was to identify the antigen (Ag) responsible for MWF-associated HP, and to optimise serological diagnosis by definition of a threshold allowing discrimination between HP patients and asymptomatic exposed workers. 13 patients, who were workers at a car engine manufacturing plant, were suspected of MWF-associated HP. Microbial analysis of 83 used MWFs was carried out. Sera from 13 MWF-associated HP patients, 12 asymptomatic exposed workers and 18 healthy unexposed controls were tested to determine their immunological responses to three Ags, including Mycobacterium immunogenum. M. immunogenum was identified in 40% of used fluids by culture and confirmed by DNA sequencing. The threshold for differentiating MWF-associated HP patients from asymptomatic exposed workers was five arcs of precipitation (sensitivity 77% and specificity 92%), as determined by electrosyneresis (ES). Using ELISA methods with protein extract from M. immunogenum, a threshold leading to 92% sensitivity and 100% specificity was established. The detection of specific antibodies against M. immunogenum Ag at high levels in case sera suggests that M. immunogenum-contaminated MWF is responsible for MWF-associated HP. To discriminate MWF-associated HP patients from asymptomatic exposed workers, we suggest a five-arc threshold for ES and a 1.6-AU threshold for ELISA methods.

Abstract
PCR screening for circulating DNA, especially when combined with antigen testing, has shown promise for the definitive diagnosis of invasive aspergillosis. False positives for Aspergillus real-time PCR assays have been described in several reports, but no sources of fungal DNA contamination could be clearly identified. We report a false-positive case for both galactomannan (GM) antigenemia and Aspergillus PCR due to nutritional supplement intake in a bone marrow transplant recipient with digestive graft-versus-host disease. Our case report also suggests that fungal DNA can pass into the serum from the intestinal tract in the same way as fungal GM. Clinicians should be aware of this possibility, so that the administration of costly, unnecessary antifungal treatments with potential adverse side-effects can be avoided.

Abstract
UNLABELLED Our prospective case-control study of 118 dwellings in Eastern France examined fungal contamination in unhealthy dwellings (n = 32) (homes with visible mold contamination and adverse health outcomes reported by the occupants), dwellings occupied by allergic patients (with medical diagnostic and positive prick-tests for molds) (n = 27) and matched control dwellings (n = 59). Unhealthy dwellings present higher airborne concentrations of Aspergillus, Penicillium, and Cladosporium than control dwellings, irrespective of the room sampled. Bedroom walls were more highly contaminated by molds than others. Dwellings occupied by allergic patients differed significantly for airborne concentrations of Penicillium only, but not for wall surface contamination, whereas bathroom walls were more highly contaminated than other rooms. Molecular identification of 12 Penicillium species showed Penicillium chrysogenum and Penicillium olsonii to be the two main species. From the total average of molds, by impaction method, useful thresholds can be given: below 170 CFU/m(3), between 170 and 560 CFU/m(3), 560 and 1000 CFU/m(3) and above 1000 CFU/m(3), respectively for dwellings with low, moderate, high, and very high concentrations. The latter would be considered a potential health hazard. PRACTICAL IMPLICATIONS A single measure of airborne concentrations of molds by impaction allows to establish useful thresholds by social services to estimate in a objective way the housing moldiness. Excluding the summer period, reproducibility of this kind of measure on 3 months, in the fixed limits, is 94.3%. The differences in terms of biodiversity of the unhealthy housing and those accommodating allergic patients imply a specific approach to decrease fungi airborne concentrations. The biodiversity of Penicillium raises the problem of the use of the single extract of Penicillium chrysogenum for skin-tests. The extent of the contaminated surfaces must be measured to assess the potential risk linked to spore contamination. Indeed, surface sampling mostly allows qualitative assessment of the environment.
