First report of a microcystin-containing bloom of the cyanobacterium microcystis aeruginosa in the La Plata River, South America.
This communication is the first registration of a toxincontaining bloom of the cyanobacterium Microcystis aeruginosa Kutzing in the La Plata River, Uruguay, ̈ South America. The occurrence of the species M. aeruginosa in the La Plata River was first registered in Ž . 1981 by CARP 1989 but without any toxicological evaluation. During the summer of 1999, short-term M. aeruginosa blooms were observ...

cyanobacterium microcystis aeruginosa bloom in aras dam reservoir
occurances of cyanobacterial bloom typically appear in eutrophic lakes which either have been affected by anthropogenic nutrient loading or are naturally rich in nutrients. microcystis blooms have been reported all over the world in freshwater ecosystems mainly due to increased population which results in increased the waste water production. the aim of this study was to recognize the basic re...
متن کاملDiversification of CRISPR within coexisting genotypes in a natural population of the bloom-forming cyanobacterium Microcystis aeruginosa.
The clustered regularly interspaced short palindromic repeat (CRISPR) confers adaptive immunity against phages via sequence fragments (spacers) derived from mobile genetic elements (MGEs), thus serving as a memory of past host-phage co-evolution. To understand co-evolutionary dynamics in natural settings, we examined CRISPR diversity in 94 isolates of Microcystis aeruginosa from a small eutroph...
متن کاملA Tribute to Disorder in the Genome of the Bloom-Forming Freshwater Cyanobacterium Microcystis aeruginosa
Microcystis aeruginosa is one of the most common bloom-forming cyanobacteria in freshwater ecosystems worldwide. This species produces numerous secondary metabolites, including microcystins, which are harmful to human health. We sequenced the genomes of ten strains of M. aeruginosa in order to explore the genomic basis of their ability to occupy varied environments and proliferate. Our findings...
