The species composition of the conjunctival microbiota newborns and first-year infants informs selection an optimal management tactics for prevention inflammatory responses. effectiveness antimicrobial therapy depends on availability susceptibility testing. most common types bacteria found in include Firmicutes, Proteobacteria, Actinobacteria, Cyanobacteria, Bacteroidetes. These bacterium are s...

Amphibian population declines around the world are associated with invasive species, pesticides, pathogens, habitat destruction, or a combination of factors. Because contamination is widespread, it represents a relevant environmental stress that can affect the ability of organisms to deal with other factors present in the environment. We examined the effects of the insecticide malathion, larger...

Managed realignment (MR) has been increasingly applied as an adaptation strategy to sea level rise in low-lying coastal areas, but the ecological consequences after flooding agricultural land with seawater are not well known. The restored Gyldensteen Coastal Lagoon represents one of largest MR projects Europe date. area served for about 150 years before being deliberately flooded 2014. This stu...

The organisms of a bluish-green layer beneath the shards of a gypsum rock were characterized by molecular techniques. The cyanobacterial consortium consisted almost exclusively of Chroococcidiopsis spp. The organisms of the shards expressed nitrogenase activity (C2H2 reduction) aerobically and in light. After a prolonged period of drought at the rock, the cells were inactive, but they resumed n...

The genes encoding the structural components of the nitrate/nitrite assimilation system of the oceanic cyanobacterium Synechococcus sp. strain WH 8103 were cloned and characterized. The genes encoding nitrate reductase (narB) and nitrite reductase (nirA) are clustered on the chromosome but are organized in separate transcriptional units. Upstream of narB is a homologue of nrtP that encodes a ni...

The identification of new pharmacophores is of paramount biomedical importance and natural products have recently been regaining attention for this endeavor.1 This renaissance is closely tied to the successful exploitation of the marine environment which harbors unmatched biodiversity that is presumably concomitant with chemical diversity.2 In particular, marine cyanobacteria are prolific produ...

Cyanobacteria blooms in marine waters are limited to only a few taxa with Trichodesmhm, Richelia, Nod&aria, and Aphanizomenon being most commonly observed. Nonhetcrocystous, nitrogen-fixing Trichodesmium spp. are found throughout low and mid-latitude oceans and seas of the Atlantic, Pacific, and Indian Oceans, and this genus is thought to be a major contributor to new nitrogen influx into these...
