Plant microbiome engineering is a promising tool to unlock crop productivity potential and exceed the yield obtained with conventional chemical inputs. We studied the effect of Aspergillus niger inoculation on in-field lettuce (Lactuca sativa) growth in soils with limiting and non-limiting P concentrations. Lettuce plants originating from inoculated seeds showed increased plant diameter (6.9%), number of leaves (8.1%), fresh weight (23.9%), and chlorophyll content (3.8%) as compared to non-inoculated ones. Inoculation of the seedling substrate just before transplanting was equally efficient to seed inoculation, while application of a granular formulation at transplanting did not perform well. Plant response to P addition was observed only up to 150 kg P2O5 ha-1, but A. niger inoculation allowed further increments in all vegetative parameters. We also employed a high-throughput phenotyping method based on aerial images, which allowed us to detect changes in plants due to A. niger inoculation. The visible atmospherically resistant index (VARI) produced an accurate prediction model for chlorophyll content, suggesting this method might be used to large-scale surveys of croplands inoculated with beneficial microorganisms. Our findings demonstrate that A. niger inoculation surpasses the yield obtained with conventional chemical inputs, allowing productivity gains not reached by just increasing P doses.

Background: In settings with low pneumococcal conjugate vaccine (PCV) coverage, multi-age cohort mass campaigns could increase population immunity, and fractional dosing could increase affordability. We aimed to evaluate the effect of mass campaigns on nasopharyngeal pneumococcal carriage of Pneumosil (PCV10) in children aged 1-9 years in Niger.

Methods: In this three-arm, open-label, cluster-randomised trial, 63 clusters of one to four villages in Niger were randomly assigned (3:3:1) using block randomisation to receive campaigns consisting of a single full dose of a 10-valent PCV (Pneumosil), a single one-fifth dose of Pneumosil, or no campaign.

Bread is a greatly consumed bakery product worldwide. Unfortunately, it is an optimal substrate for fungal contamination and deterioration (aw > 0.95), commonly caused by the genera Penicillium, Paecilomyces, and Aspergillus, resulting in significant economic losses.

Due to the high morbidity and mortality rates of invasive aspergillosis (IA) and the importance of early IA detection for successful treatment and subsequent outcome, this study aimed to determine a time course of detectable antigen in a mouse model of IA and correlate it with tissue invasion by using two novel monoclonal antibodies, 1D2 and 4E4, that can be used to detect the -derived glycoproteins. Immunocompromised mice were randomly divided into five groups: uninfected control, and inoculation with conidia from , , and . Conidia (2 × 10 cells/mL) were administered intravenously via tail vein injection.

Streptococcus pneumoniae is the main pathogen that plays a dual role, on the one hand as an asymptomatic carrier in the nasopharyngeal mucosa and on the other hand directly responsible for triggering invasive pneumococcal infections with various important localizations, especially in the pediatric population. Thus, invasive pneumococcal infections represent one of the main causes of mortality and morbidity in children under 5 years of age. Immunization is a key preventive measure against these infections.

Article Synopsis
  • Benzene, toluene, ethylbenzene, and xylene (BTEX) are hazardous compounds found in marine waters, primarily due to oil spills and industrial effluents, necessitating effective bioremediation methods in saline environments.
  • The study evaluated the halotolerance of Aspergillus niger by gradually increasing salinity to 30‰, revealing optimal growth at 25‰ with significant biomass production.
  • Batch reactor experiments showed that the adapted Aspergillus niger could efficiently degrade BTEX compounds, achieving nearly complete removal in 7 days, with benzene being the most effectively adsorbed compound on the fungal biomass.
