Strengthening Health Literacy Through Structured Sessions for Non-Communicable Diseases in Low-Resource Settings: The Learning Nest Model

Health literate self-management education is at stake for the prevention and management of non-communicable diseases in low resources settings and countries. Here we describe the Learning Nest in Ordinary Context (NA-CO in French, Nids d'Apprentissage en Contexte Ordinaire) aiming at the structuring of health education programs at the micro- (education sessions) and the meso-levels (adapted to context). The Learning Nest model was designed based on a combination on health literacy principles and on studies conducted with vulnerable people with non-communicable diseases. Observation of NA-CO active-learning sessions found them to be operational and relevant as they center on access, understanding, and use of health information while integrating the ordinary context of learners. The Learning Nest packages (including several adapted thematic sessions, training of trainers and development in context) were shown to be feasible and realistic in diverse locations (Reunion, Mali, Mayotte, Mauritius, Burundi). Qualitative and intervention studies have documented the potential usefulness of the Learning Nest model for context- and setting-specific health literacy interventions.

Identification, Virulence, and Distribution of Two Biovars of Pseudomonas syringae pv. actinidiae in New Zealand

Pseudomonas syringae pv. actinidiae, the causal agent of bacterial canker of kiwifruit, was detected for the first time in New Zealand in November 2010. Only in Bay of Plenty, one of the four regions where this pathogen had been detected, did symptoms evolve beyond leaf spots, resulting in cane die-back, wilting of canes, and canker, sometimes leading to death of the vine. Molecular analysis (cts haplotype and BOX-polymerase chain reaction [PCR] electrophoretic pattern) of strains isolated from different regions of New Zealand revealed that two biovars could be distinguished. They have been called biovar 3 and biovar 4 to differentiate them from strains from Japan (biovar 1) or Korea (biovar 2), which have a different cts haplotype or a different BOX-PCR pattern. Biovars 3 and 4 displayed different degrees of virulence, as measured by their ability to cause leaf spots on young, potted kiwifruit plants. Biovar 3, which has also been present in Italy since 2008 and in France, was found in the Bay of Plenty, where cane diebacks were observed. In contrast, no symptoms other than leaf spots have been observed in orchards where strains of biovar 4 have been isolated. We report the distribution and the disease progression of biovars 3 and 4 in New Zealand.
