Análisis molecular de las bacterias asociadas a los depósitos de desechos de Atta cephalotes (Hymenoptera: Formicidae)

Abstract: La composición bacteriana asociada a depósitos de desechos de las hormigas Atta cephalotes en cautiverio, se analizó empleando métodos de microbiología molecular. Ocho cepas bacterianas se aislaron utilizando métodos dependientes de cultivo, pertenecientes a los fila Firmicutes, Proteobacterias y Actinobacterias. De acuerdo con el análisis molecular de los perfiles de electroforesis en gel de gradiente desnaturalizante (PCR-DGGE) de las tres áreas de desecho de A. cephalotes, se encontraron diferencias en las … Show more

“…Another main isolated strain was a diazotroph in the genus Ralstonia (Order Burkholderiales), obtained from Atta sexdens , Atta laevigata , and Acromyrmex coronatus , with 16S rRNA sequence showing 91.5%–93.9% identity to other Ralstonia sequences detected in Atta sexdens libraries (Table 1 ). Bacteria in the Ralstonia genus had already been described with no obvious function in fungal gardens of Atta species (Suen et al, 2010 ), in the refuse dumps of Atta cephalotes (Ortiz‐Reyes et al, 2016 ) and the larval intestines of Atta cephalotes (Zhukova et al, 2017 ).…”

“…The collective immunity of leaf-cutting ants includes a division of labor in the colony [ 20 , 21 ] and grooming or cleaning behaviors [ 1 , 15 ] that are complemented with chemical defense mediated by metapleural gland secretions [ 19 , 21 ]. In addition to these main levels of immunity, species of Acromyrmex show yet another association with actinobacteria symbionts of the genus Pseudonocardia , which are harbored on the cuticle of workers.…”
