Summary Background The time spent on ophthalmology training in medical schools has reduced over the last decades, and the number of doctors unable to solve the most basic ophthalmic problems has increased. Methods We conducted a questionnaire with non‐ophthalmologist doctors in order to assess the confidence level of their direct ophthalmoscopy examination. This test is very important for the diagnosis of diseases that could lead to blindness, and should be learned by all medical students. Results The results showed that the doctors had difficulty and lacked confidence in performing the examination. For this reason, we have developed a new model and teaching method of direct ophthalmoscopy based on neuroscientific concepts. The number of doctors unable to solve the most basic ophthalmic problems has increased Discussion This model provides students with greater involvement in the learning process as they build their own model, a practice that shows the concepts of the physics behind direct ophthalmoscopy. Implication This will benefit the population by providing an early diagnosis of diseases that threaten life and vision.

The genus Bradyrhizobium is considered as the probable ancestor lineage of all rhizobia, broadly spread in a variety of ecosystems and with remarkable diversity. A polyphasic study was performed to characterize and clarify the taxonomic position of eight bradyrhizobial strains isolated from indigenous legumes to Western Australia. As expected for the genus, the 16S rRNA gene sequences were highly conserved, but the results of multilocus sequence analysis with four housekeeping genes (dnaK, glnII, gyrB and recA) confirmed three new distinct clades including the following strains: (1) WSM 1744T, WSM 1736 and WSM 1737; (2) WSM 1791T and WSM 1742; and (3) WSM 1741T, WSM 1735 and WSM 1790. The highest ANI values of the three groups in relation to the closest type strains were 92.4, 92.3 and 93.3 %, respectively, below the threshold of species circumscription. The digital DNA–DNA hybridization analysis also confirmed new species descriptions, with less than 52 % relatedness with the closest type strains. The phylogeny of the symbiotic gene nodC clustered the eight strains into the symbiovar retamae, together with seven Bradyrhizobium type strains, sharing from 94.2–98.1 % nucleotide identity (NI), and less than 88.7 % NI with other related strains and symbiovars. Morpho-physiological, phylogenetics, genomic and symbiotic traits were determined for the new groups and our data support the description of three new species, Bradyrhizobium archetypum sp. nov., Bradyrhizobium australiense sp. nov. and Bradyrhizobium murdochi sp. nov., with WSM 1744T (=CNPSo 4013T=LMG 31646T), WSM 1791T (=CNPSo 4014T=LMG 31647T) and WSM 1741T (=CNPSo 4020T=LMG 31651T) designated as type strains, respectively.
