Puerperal infection is a common complication during postnatal period in developing countries. Bacterial species, drug resistance, and genetic characteristics were investigated for a total of 470 isolates from puerperal infections in Bangladesh for a 2-year period (2010-2012). The most common species was Escherichia coli (n=98), followed by Enterococcus faecalis (n=54), Staphylococcus haemolytic...
Escherichia albertii is a recently recognized close relative of Escherichia coli. This emerging enteropathogen possesses a type III secretion system (T3SS) encoded by the locus of enterocyte effacement, similar to enteropathogenic and enterohemorrhagic E. coli (EPEC and EHEC). Shiga toxin-producing strains have also been identified. The genomic features of E. albertii, particularly differences ...
Plocamium cartilagineum is a common red alga on the benthos of Antarctica and can be a dominant understory species along the western Antarctic Peninsula. Algae from this region have been studied chemically, and like "P. cartilagineum" from other worldwide locations where it is common, it is rich in halogenated monoterpenes, some of which have been implicated as feeding deterrents toward sympatr...
Species of the genus Moina Baird (Cladocera: Moinidae) often dominate freshwater crustacean communities in temporary water bodies. Several species of Moina are used as food for fish larvae in aquaculture, as bioindicators in toxicological studies, and as common subjects for physiological studies. The aim of this paper is to estimate biodiversity of Moina in northern Eurasia using the standard D...
the japanese threadfin bream, nemipterus japonicus, the most abundant and crucially economic nemipterus species is widespread throughout the indo-west pacific. the species has been studied widely for various aspects but genetic studies are scanty. this preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of n. japonicus...
conclusions these results indicate that the pcr method is a powerful genotypic assay for the detection of adhesin-encoding operons. thus, this assay can be recommended for clinical use to detect virulent urinary e. coli strains, as well as epidemiological studies. materials and methods a total of 100 upec isolates were obtained from urine samples of patients with uti. the prevalence of 5 virule...
In Uruguay, the mortality of dairy calves due to infectious diseases is high. Escherichia coli a natural inhabitant intestinal microbiota, but can cause several infections. The aim work was characterize E. isolates from and extraintestinal origin dead newborn calves. Using PCR, virulence gene characteristics pathogenic were searched. molecularly characterized phylogroup, serogroup Stx subtype d...
Background: Segregation of Escherichia coli (E. coli) into the phylogenetic groups was observed in experiments so that group B2 contained enteropathogenic E. (EPEC) strains and extraintestinal pathogenic (ExPEC). Objectives: This study aimed to identify extended-spectrum Cephalosporins resistant isolated from stool healthy children under 10 years old. Methods: One hundred broad-spectrum were co...
