The increase in the world population brings with it the need for food production and therefore the search for technological alternatives to satisfy this demand. According to the Food and Agriculture Organization of the United Nations (FAO), it is necessary to evaluate both the effectiveness and the safety of all products used in agriculture. The Institute of Plant Biotechnology of the province of Villa Clara, Cuba, immersed in the solution of this problem, has shown that two biopreparations CCIBP-C5 (Bacillus pumilus) and CCIBP-A5 (Bacillus amyloliquefaciens) have an effect on plant growth and activity against phytopathogenic fungi. However, there is no evidence of its safety on non-target organisms in the ecosystem. Terrestrial ecotoxicology is the branch of science devoted to predicting said impact on representative organisms. Four tests were carried out to evaluate the acute toxicity ...

The aim of this study was to evaluate the in vitro activity of furvina against microorganisms isolated from the skin of canines with piodermatitis in of Santa Clara, Cuba. Resistance to antibacterial agents was assessed by the diffusion method in agar and the in vitro activity was evaluated quantitatively by the broth macrodilution method according to international clinical laboratory standards. Fifty multiresistant strains were identified, 47 from the genus Staphylococcus and 3 from Pseudomonas. The Fisher’s exact test showed highly significant sensibility of microorganisms of the genus Staphylococcus to ciprofloxacin. All strains were resistant to at least three antimicrobials. The Minimum Inhibitory Concentration (MIC) for furvina ranged from 2-16 mg/ml where 83.2% of the strains having a MIC of 4-8 mg/mL. The Minimum Bactericidal Concentration (MBC) ranged from 4-32 mg/ml where 86....

Los objetivos del presente estudio consistieron en aislar microorganismos de la piel de caninos con piodermitis de la ciudad de Santa Clara, Cuba, y evaluar la actividad in vitro de la furvina frente a los microorganismos aislados. La resistencia a los agentes antibacterianos se determinó mediante el método de difusión en agar y la actividad in vitro se evaluó cuantitativamente mediante macrodilución en caldo según procedimientos internacionales. Se identificaron 50 cepas multirresistentes, siendo 47 del género Staphylococcus y 3 del género Pseudomonas. El test exacto de Fisher demostró sensibilidad altamente significativa de los microorganismos del género Staphylococcus para la ciprofloxacina. Todas las cepas fueron resistentes al menos a tres de los antibacterianos enfrentados. Las muestras evaluadas mostraron una Concentración Inhibitoria Mínima (CIM) entre 2-16 g/ml fr...

Los moluscos son un grupo altamente diverso en apariencia, anatomía, fisiología y ecología y representa el segundo mayor grupo de invertebrados. El objetivo del presente trabajo consistió en confeccionar un modelo matemático en función de variables meteorológicas, que permita predecir la distribución y abundancia de los gasterópodos fluviales y terrestres en el municipio Santa Clara, Cuba. Para ello se analizaron las cinco áreas de salud del municipio, en el período comprendido entre marzo y julio del 2019. Se colectaron especímenes en los ecosistemas con uso humano de estas áreas de salud, así como datos meteorológicos de la estación que mantiene vigilancia sobre ellas. En el desarrollo del modelo predictivo se empleó la Modelación Objetiva Regresiva (ROR). El área de salud con una mayor abundancia y diversidad de gasterópodos fue Capitán Roberto Fleites, la especie...
