Biodiversidad de protistas amébidos de vida libre en México

Abstract: de 142 publicaciones del período de 1841-2012. En el recuento se registraron 315 especies diferentes de amibas. Los grupos dominantes fueron Amebozoa, Rhizaria y Excavata, con una importante contribución de las amibas testadas y de los gimnamebidos del tipo acantamebidos. La mayoría de los trabajos se han realizado en los estados del centro de la República Mexicana, especialmente en el Distrito Federal, correspondiendo con la ubicación de los principales grupos de investigación. Nueve estados no tienen ningún … Show more

“…Amoebas of the genus Acanthamoeba present two stages during their life cycle: (a) trophozoite (13-40 μm in diameter) or metabolically active vegetative form, which feeds on bacteria and smaller organisms and multiplies by binary fission, giving rise to two identical daughter cells and (b) cysts (6-10 μm in diameter) or forms of resistance [41][42][43][44]. Other amoebas, such as those in the genus Naegleria, have three morphological stages, one of which is a temporary amoeboflagellar stage in which the organism does not feed or reproduce and only serves to move to a better microenvironment [1,45]. The cysts originate from the production of a protective covering by the trophozoite when it is under extreme environmental conditions such as changes in temperature, humidity, pH, nutrients, osmotic pressure, and among others, which covers it and turns it into a form of resistance.…”

“…Therefore, it plays an essential biological role in the control of bacterial populations. [ 1 , 2 ]. Amoebas are found in various environments; however, environmental conditions can affect their survival, such as pH, temperature, hydrogen sulfide concentration, and salinity.…”

“…Published studies from Mexico focused on testate amoebae in soils and mosses of diverse terrestrial ecosystems (Golemansky, 1967;Bonnet, 1977;Bobrov & Krasil'nikov, 2011;Bobrov, Krasil'nikov, & García-Calderón, 2013;Gallegos-Neyra, Lugo-Vázquez, Calderón-Vega, Sánchez-Rodríguez, & Mayén-Estrada, 2014). There is also information from protozoological studies focused on lakes (López-Ochoterena & Roure-Cane 1970;Aladro, Reyes, Olvera, & Robles, 2007), cenotes (van Hengstum et al, 2008) and caves (Osorio-Tafall, 1943;Hoffmann, Palacios, & Morales-Malacara, 1986).…”

“…Esta escasez de estudios está ligada al también reducido número de investigadores en este campo en el país. En México se tienen registradas alrededor de 146 especies de protistas flagelados heterótrofos (Mayén-Estrada et al, 2014a), 995 especies de ciliados de vida libre (Mayén-Estrada et al, 2014b) y 315 especies de amebas de vida libre (Gallegos-Neyra et al, 2014). Para el Estado de Querétaro solo se han registrado 13 taxones de protistas (Sigala-Regalado et al, 2011).…”
