Comparative study on prevalence and association of some virulence factors with extended spectrum beta-lactamases and AmpC producing Escherichia coli

The aim of this study was to gain further insight into the interplay between both extended spectrum β-lactamase (ESBL) and AmpC enzymes and different virulence factors (VFs) among Escherichia coli (E. coli) isolated from Mansoura University Hospitals, Egypt. For this purpose 100 E. coli isolates were collected from different clinical sources. All isolates were investigated for production of ESBL and AmpC enzymes....

Microbial activity in two soils with different clay content contaminated by different diesel/biodiesel mixtures

Biodiesel is an alternative energy source that has a high biodegradability potential and low toxicity, contributing to ecosystem impact reductions. The aim of this study was to determine, by the natural attenuation technique, the microbial activity of two soils: one clayey (CLA) and the other sandy (SAN), contaminated with different concentrations of biodiesel blended with diesel (B0, B5, B20 and B100) simulating a...

Cyanide influence on the growth of mycotoxigenic fungi from cassava flour in vitro

The hypothesis that residual cyanide present in cassava flour influences the growth of mycotoxigenic Aspergillus was established. Therefore, cyanide concentrations were measured in three types of flour: mixed, dry and watery (n=30), as the basis for the establishment of doses to be used. Fungi sowing were performed in solid Saboraud medium with a central well (500 μL), in which 5, 10, 15 and 20 mg CN kg-1...

Molecular screening for the presence of Streptococcus agalactiae, Escherichia coli and Listeria monocytogenes in samples of milk from dairy herds

This study aims to verify the predominance of contamination with pathogenic microorganisms in dairy herds. In order to validate the initially used methodology, an artificial contamination was conducted in commercially acquired whole UHT milk, with strains of Listeria monocytogenes, Streptococcus agalactiae and Escherichia coli, in final concentrations from 2.10-7 to 2.100 CFU/mL, which were submitted to a DNA extraction...

Mycobiota from the eggs, nests and stillbirths of Eretmochelys imbricata Linneus 1766 (Testudines: Cheloniidae) in Pernambuco State, Brazil

Eretmochelys imbricata Linneus 1766 was the subject of trade due to egg collection and consumption of the flesh of the females, being the fishery one of the main impacts towards the coastal area. The pathogens are also worrying factors of mortality of sea turtles especially those caused by fungi; these can cause the death of embryos and cutaneous mycoses. This study aimed to investigate the mycoflora isolated from soil,...

Prevalence and characterization of carbapenemase producing isolates of Enterobacteriaceae obtained from clinical and environmental samples: Efflux pump inhibitor study

The present study was undertaken to screen for carbapenem resistance and the ability of efflux pump inhibitors to inhibit this resistance in enterobacteriaceae strains isolated from clinical specimens from patients attending Jawaharlal Institute of Post Graduate Medical Education and Research (JIPMER) hospital and water samples in and around Puducherry. A total of 425 carbapenem resistant isolates from clinical samples...

Candida albicans ssp. dubliniensis stat.et comb. nov., a new combination for Candida dubliniensis based on genetic criteria

One accredited species, Candida albicans subspecies dubliniensis, has been proposed to replace the existing designations of Candida dubliniensis. The study of the genetic diversity among the clinical isolates of C. albicans and C. dubliniensis was performed based on the amplified transposable intron region in the 25S rRNA gene. This study attempts to verify the unequivocal understanding of the genetic relationship...
