The Domestic Environment and the Lung Mycobiome.

ABSTRACT: This study analyzes the relationship between the mycobiome of the Lower Respiratory Tract (LRT) and the fungi in the domestic environment. Samples studied consisted of Broncho-Alveolar Lavage (BAL) from 45 patients who underwent bronchoscopy for different diagnostic purposes, and dust and air from the houses (ENV) of 20 of them (44.4%). Additionally, five bronchoscopes (BS) were also analyzed and negative controls were included for every procedure. All samples were processed for DNA extraction and cultures, which were performed in Sabouraud Dextrose and Potato Dextrose Agar. The fungal Internal Transcribed Spacer (ITS2) was sequenced by the Solexa/Illumina system and sequences were analyzed by QIIME 1.8.0 and compared with the UNITE Database for identification. The similarity between the two fungal communities (BAL and ENV) for a specific patient was assessed via the percentage of coincidence in the detection of specific operational taxonomic units (OTUs), and about 75% of co-occurrence was detected between the mycobiome of the LRT and the houses. Cultures confirmed the presence of the core mycobiome species. However, the low rate of isolation from BAL suggests that most of its mycobiome corresponds to non-culturable cells. This likely depends on the patient's immune system activity and inflammatory status.

Project description:Waterborne enteric viruses are an emerging cause of disease outbreaks and represent a major threat to global public health. Enteric viruses may originate from human wastewater and can undergo rapid transport through aquatic environments with minimal decay. Surveillance and source apportionment of enteric viruses in environmental waters is therefore essential for accurate risk management. However, individual monitoring of the >100 enteric viral strains that have been identified as aquatic contaminants is unfeasible. Instead, viral indicators are often used for quantitative assessments of wastewater contamination, viral decay and transport in water. An ideal indicator for tracking wastewater contamination should be (i) easy to detect and quantify, (ii) source-specific, (iii) resistant to wastewater treatment processes, and (iv) persistent in the aquatic environment, with similar behaviour to viral pathogens. Here, we conducted a comprehensive review of 127 peer-reviewed publications, to critically evaluate the effectiveness of several viral indicators of wastewater pollution, including common enteric viruses (mastadenoviruses, polyomaviruses, and Aichi viruses), the pepper mild mottle virus (PMMoV), and gut-associated bacteriophages (Type II/III FRNA phages and phages infecting human Bacteroides species, including crAssphage). Our analysis suggests that overall, human mastadenoviruses have the greatest potential to indicate contamination by domestic wastewater due to their easy detection, culturability, and high prevalence in wastewater and in the polluted environment. Aichi virus, crAssphage and PMMoV are also widely detected in wastewater and in the environment, and may be used as molecular markers for human-derived contamination. We conclude that viral indicators are suitable for the long-term monitoring of viral contamination in freshwater and marine environments and that these should be implemented within monitoring programmes to provide a holistic assessment of microbiological water quality and wastewater-based epidemiology, improve current risk management strategies and protect global human health.

Project description:This article describes two cases of notoedric mange concurrent with aelurostrongylidosis in two domestic-owned cats from a rural environment in Romania. Two European shorthair cats originating from the same litter were referred to our clinic, at 2 months apart, with a history of skin lesions, pruritus, weight loss, and respiratory signs. Cats lived mainly outdoor together with the queen and a third littermate. The latter two expressed the same clinical signs and had died before the presentation of the first cat. None of the four cats was vaccinated, dewormed, or treated for external parasites. Coat brushing, skin scrapings, skin cytology, earwax direct microscopic examination, and coproparasitological techniques (flotation and Baermann methods) were used as laboratory procedures. A blood sample was also collected for hematology, blood biochemistry, and feline immunodeficiency virus/feline leukemia virus (FIV/FeLV) test. Notoedres cati mites in high numbers were identified by all complementary tests, alongside fleas and Aelurostrongylus abstrusus first-stage larvae. The blood analysis revealed neutrophilia, and the FIV/FeLV fast test was negative. The cats were successfully treated off-label with selamectin spot-on formulation (Stronghold®, Zoetis) three times at 1- or 4-week intervals. Furthermore, they were treated with amoxicillin trihydrate/clavulanic acid, housed indoor, and fed with a commercial diet. Before presentation to the clinic, the female cat was unsuccessfully treated with a combination of fipronil, S-methoprene, eprinomectin, and praziquantel. During this period, the female cat remained outdoor and fed with home wastes. The cats become negative for A. abstrusus L1 larvae after 2-4 months of treatment. The owners developed pruritic skin lesions 1 month after introducing the first cat in the house. In conclusion, notoedric mange and aelurostrongylidosis can be treated successfully with selamectin as a spot-on formulation and the treatment must be continued until no parasite will be detected through specific techniques. The success of treatment depends on improving the quality of animal life (nutrition and hygiene) and treatment of secondary complications.

Project description:Achromobacter spp. are nonfermentative Gram-negative bacilli considered emergent pathogens in cystic fibrosis (CF). Although some cross-transmission events between CF patients have been described, Achromobacter strains were mostly patient specific, suggesting sporadic acquisitions from nonhuman reservoirs. However, sources of these emergent CF pathogens remain unknown. A large collection of specimens (n = 273) was sampled in the homes of 3 CF patients chronically colonized by Achromobacter xylosoxidans with the aim of evaluating the potential role of domestic reservoirs in sustaining airway colonization of the patients. Samples were screened for the presence of Achromobacter by using genus-specific molecular detection. Species identification, multilocus genotypes, and antimicrobial susceptibility patterns observed for environmental isolates were compared with those of clinical strains. Patient homes hosted a high diversity of Achromobacter species (n = 7), including Achromobacter mucicolens and A. animicus, two species previously isolated from human samples only, and genotypes (n = 15), all showing an overall susceptibility to antimicrobial agents. Achromobacter strains were mostly isolated from indoor moist environments and siphons, which are potential reservoirs for several CF emerging pathogens. A. xylosoxidans, the worldwide prevalent species colonizing CF patients, was not the major Achromobacter species inhabiting domestic environments. A. xylosoxidans genotypes chronically colonizing the patients were not detected in their household environments. These results support the notions that the domestic environment could not be incriminated in sustained patient colonization and that after initial colonization, the environmental survival of A. xylosoxidans clones adapted to the CF airways is probably impaired.IMPORTANCE Achromobacter spp. are worldwide emerging opportunistic pathogens in CF patients, able to chronically colonize the respiratory tract. Apart from regular consultations at the hospital CF center, patients spend most of their time at home. Colonization from nonhuman sources has been suggested, but the presence of Achromobacter spp. in CF patients' homes has not been explored. The domestic environments of CF patients chronically colonized by Achromobacter, especially wet environments, host several opportunistic pathogens, including a large diversity of Achromobacter species and genotypes. However, Achromobacter genotypes colonizing the patients were not detected in their domestic environments, making it unlikely that a shuttle between environment and CF airways is involved in persisting colonization. This also suggests that once the bacteria have adapted to the respiratory tract, their survival in the domestic environment is presumably impaired. Nevertheless, measures for reducing domestic patient exposure should be targeted on evacuation drains, which are frequently contaminated by CF opportunistic pathogens.
