The two main classes of phages are lytic or virulent and lysogenic or temperate. In comparison with antibiotics, to deal with bacterial infections, phage therapy is thought to be more effective. In 1921, the use of phages against bacterial infections was first demonstrated. Later on, in humans...
This study investigated the effect of different classes of antibiotics on different phases of biofilm formed by Klebsiella pneumoniae. The organism was grown in different phases relevant to biofilm formation: planktonic cells at mid-log phase, planktonic cells at stationary phase, adherent monolayers ...
An overview of each of the classes of catalysts is a helpful starting point in learning analytical chemistry and understanding what happens at the molecular level when you mix substances together and a reaction occurs. Catalysts and their associated catalytic reactions come in three main types: homog...
Although Romania is a leading country in the consumption of certain classes of antibiotics in Europe (Popescu et al., 2016), limited information is available on the consumption of antimicrobials in human healthcare settings (e.g., hospitals, long-term care facilities, and private practices). ...
Describe the four mechanisms used by bacterial species to generate resistance to antibiotics. Why are there five different classes of antibodies in the body? Explain how vaccines provide protection against disease. In your response, discuss the ac...
Studies on the gut microbiota of animals have largely focused on vertebrates. The transmission modes of commensal intestinal bacteria in mammals have been well studied. However, in gastropods, the relationship between gut microbiota and hosts is still po
Antibiotic resistance (AR) among pathogens is an increasing problem for medical and veterinary treatment. During the last decades the number of AR infections has been on the rise, and this trend will certainly continue [1]. The vast majority of antibiotic classes currently used originate from natu...
discovered multiple precursor classes throughout influent, effluent, and biosolids. The findings indicated that perfluorophosphonic acids (PFPAs) were found in every biosolid sample (100%) and fluorotelomer phosphate diesters (di-PAPs) in 92% of them. The analysis of mass flow patterns showed that...
There is a discovery void and the pipeline of new classes of antibiotics in clinical development is almost empty. Therefore, it is important to understand the structure activity relationships (SAR) of current chemical classes as that can help the drug discovery community in their efforts to ...
(Fig.4B). The other lipids were mainly categorized into classes of fatty acids, sterol lipids, and sphingolipids. The lipids relevant to prenol lipids and polyketides class constituted a relatively small percentage of all lipids induced by MTB‐infection (Fig.4B). For the categorization of main...
