Gram-negative bacilli isolated from the hospital environment - Bok av Manel Debabza - Häftad

Gram-negative bacilli isolated from the hospital environment - Bok av Manel Debabza - Häftad

In this study, 306 Gram-negative bacilli (GNB) strains were isolated from the hospital environment, 74.51% of them enterobacteria. Antibiotic susceptibility testing revealed resistance to various families of antibiotics, in particular ¿-lactam antibiotics, although imipenem, aminoglycosides and fluoroquinolones were remarkably effective. Extended-spectrum beta-lactamase (ESBL) detection tests were used to characterize 114 strains of ESBL-producing Enterobacteriaceae (EBLSE). Analysis of plasmid..

Usefulness of Gram stain in urinary tract infection in children - Bok av Grace Carrera - Häftad

Usefulness of Gram stain in urinary tract infection in children - Bok av Grace Carrera - Häftad

Urinary tract infection (UTI) has a prevalence of 2-5%, and an incidence of 5-8% in children under 5 years of age, with 80-90% of its aetiology being E. coli. The definitive diagnosis is made by urine culture, although Gram stain is recommended for immediate therapeutic decisions, with a sensitivity of 100% and a specificity of 87%. This study analyses the benefits of this type of procedure and avoids the mismanagement of antibiotics in the paediatric population.

Use of plant-associated bacteria - Bok av Ralf Bruno Moura Lopes - Häftad

Use of plant-associated bacteria - Bok av Ralf Bruno Moura Lopes - Häftad

Gram-negative bacteria are important etiological agents of diseases in agricultural crops. The regulation of virulence of these phytopathogens is frequently mediated by the population density-dependent control mechanism of gene expression, quorum sensing. Thus, the present study aimed to evaluate the potential of endophytic (gram-positive) actinobacteria to inhibit this mechanism in gram-negatives. Isolates belonging to the species Microbacterium testaceum, Microbacterium phyllosphaerae and Rhodococcus..

Antibacterial and modulatory evaluation of aloe ethanolic extract - Bok av Carolinne Alves Oliveira Souza - Häftad

Antibacterial and modulatory evaluation of aloe ethanolic extract - Bok av Carolinne Alves Oliveira Souza - Häftad

Aloe vera, popularly known as babsosa, is a plant from the Xanthorreaceae family found in tropical regions and has long been used in various parts of the world for medicinal and cosmetic purposes. The aim of this study was to evaluate the antibacterial and modulating activity of the ethanolic extract of aloe vera barbadensis miller against Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa.

Mechanisms of bacterial resistance to antibiotics - Bok av Nadia Safia Chenouf - Häftad

Mechanisms of bacterial resistance to antibiotics - Bok av Nadia Safia Chenouf - Häftad

Bacterial resistance to antibiotics has become one of the major threats facing the global community. It can result either from mutations or from the acquisition of resistance genes carried by mobile (plasmids, transposons, insertion sequences) or mobilizable (integrons) genetic elements. The aim of this book is to provide an overview of the main resistance mechanisms encountered in both Gram-negative bacteria (E. coli) and Gram-positive bacteria (Staphylococcus aureus). It also describes the main..

Low Vision - Bok av Yariel Morejón - Häftad

Low Vision - Bok av Yariel Morejón - Häftad

According to the World Health Organization (WHO), low vision is a clinical problem that affects more people than blindness. There are approximately 285 million visually impaired people in the world; of these, 246 million have low vision. The number of disabled people is increasing every day worldwide, making low vision both a problem and a challenge. Despite technological advances in the field of Ophthalmology, visual rehabilitation is still a very important procedure in patients with low vision,..

Raw Milk Microbiological Quality - Bok av Mélika Mankai - Häftad

Raw Milk Microbiological Quality - Bok av Mélika Mankai - Häftad

Gram-negative psychrotrophic bacteria make up the dominant microflora of chilled raw milk. The dominant species identified, whatever the duration of refrigeration considered, are essentially: Aeromonas caviae (36%), Chryseomonas luteola (15%), Pseudomonas fluorescens (29%), Pseudomonas putida (11%) and Pseudomonas cepacia (3%). In addition to the presence of significant aminopeptidase and esterase activities in these psychrotrophic germs, they are also endowed with intense thermostable extracellular..

Enterococci and their virulence genes - Bok av Salaheddine Redouane - Häftad

Enterococci and their virulence genes - Bok av Salaheddine Redouane - Häftad

Enterococci are gram-positive bacteria with an aero-anaerobic metabolism. They are considered opportunistic pathogens that normally live in the intestinal flora, but can cause septicaemia, urinary tract infections, abdominal infections and endocarditis. They are considered to be responsible for more than 10% of hospital-acquired infections. The pathogenic power of enterococci is due to the presence of virulence genes which code for membrane proteins, toxins and enzymes. These are considered the virulence..

Cholera trends from 2017 to 2020 in the DRC: - Bok av Léon Shongo Onasaka - Häftad

Cholera trends from 2017 to 2020 in the DRC: - Bok av Léon Shongo Onasaka - Häftad

Cholera is a contagious infectious diarrheal disease, the severe form of which can be fatal within hours if not treated immediately. This strictly human disease is caused by Vibrio cholerae, a curved Gram-negative bacillus with a unique polar flagellum that gives it the high mobility characteristic of this bacterium.According to WHO reports, between 100,000 and 300,000 new cases of cholera have been reported worldwide each year over the last ten years. However, these figures underestimate the scale..

Determination of Ehrlichia canis in the city of Iquique, Chile - Bok av Daniel Martinez - Häftad

Determination of Ehrlichia canis in the city of Iquique, Chile - Bok av Daniel Martinez - Häftad

A study was carried out to determine the presence of Ehrlichia canis, a gram-negative and obligate intracellular bacterium, which plays a zoonotic role in public health, as it is transmitted by Rhipicephalus sanguineus \brown dog tick\ that bites and occasionally infects humans. A total of 49 blood samples were obtained randomly from dogs without considering breed, sex or age; 32 of the samples were obtained in the Municipal Kennel of Iquique, while the other 17 were obtained in veterinary clinics..

A review of Kermani inventor Naiem Ahmadinejad's inventions - Bok av Naiem Ahmadinejadfarsangi - Häftad

Three to four weeks before harvest, we reduce the light in the greenhouse so that the tea leaves are in the shade. Covering the leaves causes the tea leaves to produce more chlorophyll and the amino acid L-theanine. Greenhouse green tea contains more antioxidants per gram than any other vegetable or fruit. EGCG (epigallocatechin gallate) is a type of antioxidant found in abundance in greenhouse tea, which belongs to the catechin category. Catechins prevent the formation of free radicals in the body,..
