Biopriming of maize seeds with plant growth-promoting bacteria isolated from the earthworm Aporrectodea molleri: effect on seed germination and seedling growth.

Earthworms have become a potential source of multi-beneficial bacteria and effective bioinoculants. Seed biopriming is an efficient inoculation method to apply bacteria prior to sowing, which enhances the chances of bacterial candidates to colonize the rhizosphere and/or establish a liaison with the plant. In this study, we evaluated plant growth-promoting traits of bacterial strains isolated from the earthworm's Aporrectodea molleri chloragogenous tissue. In addition, we investigated their prospective use as biopriming agents to enhance Zea mays germination and seedling growth. Results were subjected to principal component analysis for potential correlations between the studied parameters. The bacterial strains displayed different in vitro plant growth-promoting characteristics and were efficient when applied in vivo as they significantly increased maize germination rate (26-78%), root elongation (67-84%), seedlings fresh weight and dry weight. Aeromonas encheleia TC22 was the most significant strain to influence germination due to its high ability to produce indole-3-acetic acid, and along with Pseudomonas azotoformans TC1, they were the most proficient at enhancing seedling root elongation and biomass, which was significantly correlated with their in vitro plant growth-promoting traits. Our findings indicate that isolates TC22 and TC1 are potent bio-primers for maize seeds and should be tested further for their use as biopriming inoculants.

Treatment of an acute deep hand burn in a lowincome country with no available microsurgery: a case report.

Deep hand burns usually lead to joint and tendon exposure. A simple skin graft is insufficient to achieve healing. Soft tissue reconstruction represents a surgical challenge that ranges from the simplest to the most complex flaps. In some areas, microsurgery is not technically possible. Choice is then limited to pedicled distant flaps such as the abdominal wall flap-graft. We report a case of an acute burned hand with exposure of metacarpophalangeal joints from the second to the fourth radius as well as proximal inter phalangeal joints from the second to the fifth radius and extensor tendons, treated in the burns and wound care unit of the Sylvanus Olympio Teaching Hospital in Lomé. The dorsum hand and fingers were covered with a pedicled abdominal flap-graft that was severed in two stages at 22 and 29 days. We achieved good results (sensitivity S3+, useful aesthetic hand) at two-year follow up.

Les brûlures profondes de la main conduisent habituellement à une exposition articulaire et tendineuse. La reconstruction des parties molles représente un challenge chirurgical qui va de la technique la plus simple au lambeau le plus complexe. Dans certaines contrées, la microchirurgie n'est pas techniquement possible et le choix se limite à l'utilisation de lambeau pédiculé à distance, comme le lambeau-greffe abdominal; nous rapportons un cas de brûlure récente de la main avec exposition des articulations métacarpo phalangiennes du second au quatrième rayon avec de plus une atteinte des articulations inter phalangiennes proximales du second jusqu'au cinquième rayon et exposition des tendons extenseurs. Ce patient a été pris en charge dans l'Unité des brûlés et des Plaies et Cicatrisation du Centre Hospitalier Universitaire Sylvanus Olympio de Lomé. La face dorsale de la main et des doigts a été couverte par un lambeau-greffe pédiculé abdominal, qui fut sevré en 2 étapes (22ème et 29ème jour). Nous avons obtenu de bons résultats sur le plan de la sensibilité ainsi que sur l'aspect esthétique chez ce patient après deux ans de suivi.
