Focus on bacterial biofilms
Bacterial biofilms are colonies of bacterial cells embedded in their self-produced matrix composed of polysaccharides, DNA, and proteins. They protect bacterial cells against antibiotics, antibacterial agents, soaps and detergents, and shear stress. Some of the most common biofilm-associated infections in humans include urinary tract infections, infection of wounds and surgical sites, diabetic foot ulcers, dental caries (tooth decay) and gingivitis (gum inflammation), ventilator-associated infections, sinusitis, microbial keratitis, secondary infection related to Covid-19 and other viral infections, and so on. Bacterial resistance to common antibiotics (e.g., penicillin, gentamycin, erythromycin, ciprofloxacin, etc.) is driving us to a catastrophic failure of our health systems. Strategies to develop novel antibacterial agents and technology must be prioritized to combat and eradicate biofilms and their associated challenges. This book provides a comprehensive overview of biofilms with chapters on bacterial virulence factors, quorum sensing in bacteria, antimicrobial resistance in bacteria, strategies to develop new antibacterial agents, and much more.
Effect of Cranberry in the Treatment of E. Coli
Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. It may cause severe stomach cramps, bloody diarrhoea, vomiting and UTI. You may be exposed to E. coli from contaminated water or food especially raw vegetables and undercooked ground beef. Healthy adults usually recover from infection with E. coli within a week. Young children and older adults have a greater risk of developing a life-threatening form of kidney failure. Cranberries are a popular superfood. People can consume them in the form of a sauce or a juice. They can also add them to stuffing, casseroles, or dessert. In fact, research has linked the nutrients in cranberries to a lower risk of urinary tract infection (UTI), the prevention of certain types of cancer, improved immune function, and decreased blood pressure
Diabetes mellitus and bacterial and fungal urinary tract infection
Diabetes mellitus is a heterogeneous group of disorders characterized by variable degrees of insulin resistance, impaired insulin secretion, and increased glucose production. Patients with type 2 diabetes mellitus are at increased risk of infections, with the urinary tract being the most frequent infection site. Various impairments in the immune system, in addition to poor metabolic control of diabetes, and incomplete bladder emptying due to autonomic neuropathy, may all contribute in the pathogenesis of urinary tract infections (UTI) in diabetic patients. Factors that were found to enhance the risk for UTI in diabetics include age, metabolic control, and long-term complications, primarily diabetic nephropathy and cystopathy. The spectrum of UTI in these patients ranges from asymptomatic bacteriuria (ASB) to lower UTI (cystitis), pyelonephritis, and severe urosepsis.
Les infections urinaires = Urinary tract infections
Les Infections urinaires provides an update on knowledge concerning the epidemiology of community-based infection, on the mechanisms of bacterial resistance and on certain aspects of the disease useful to urologists as well as infectious diseases, gynecologists, emergency physicians and attending physicians. . Nosocomial urinary tract infection is approached from the perspective of risk factors. Acute and chronic prostatitis was the subject of a consensus conference supported by the World Health Organization within the framework of the International Consensus Conferences in Urology in Paris. The full text and the recommendations are reported with the consent of their authors. This book is an author's book and not an author's book because urinary tract infection is multiple, complex and justifies a multidisciplinary approach.
Advances in Microbiology, Infectious Diseases and Public Health ; Vol.15
Focuses on current progress in the broad field of medical microbiology, and covers both basic and applied topics related to the study of microbes, their interactions with human and animals, and emerging issues relevant for public health. Original research and review articles present and discuss multidisciplinary findings and developments on various aspects of microbiology, infectious diseases, and their diagnosis, treatment and prevention.
