In this work, Leifsonia xyli subsp. xyli pure culture is obtained from Cuban varieties of sugarcane, and the difficulties present till now regarding the isolate of this phytobacterium of fastidious nature are decreased. The typical pleomorphism of this bacterial species and the total coincidence of the biochemical and molecular characteristics that identify it, are evindenced. It is counted for the first time in Cuba with characterized isolates which can be used in future researches and services, as well as in the antisera obtaining for the serological diagnostic of this important disease.

This paper presents a systematic review of the scientific literature on participatory monitoring (PM) in Mexico in order to understand its dimensions and usefulness for decision-making and public environmental policies. For this, a conceptual scheme of the mp is proposed from the socioecosystemic perspective (SEPM) in accordance with interdisciplinary scientific approaches and citizen science, through eight structural dimensions. The qualitative method of analysis was based on the application of the Search, Assessment, Synthesis, Analysis (SALSA) protocol, and the use of Scopus and scielo databases. The results first describe general spatial and temporal trends for Latin America and, subsequently, focus on the analysis of 24 preselected and coded publications for Mexico, considering monitoring criteria related to eight structural dimensions of the conceptual scheme. It is observed that the SEPM in Mexico has increased since the year 2000, the scale has been local, the land tenure dominant of social property, the regional scope, and has been more applied to the forest, water and agroforestry socio-ecosystems. The sepm has great potential for decisionmaking at different organizational levels, especially when it is implemented in an integrated manner. [ABSTRACT FROM AUTHOR]
