“…On the other hand, lincosamides are a highly important antibiotics class, used against infections caused by Enterococcus sp., and Staphylococcus aureus. Due to the reduced susceptibility of S. aureus to -lactam antibiotics, the clinical use of macrolides and lincosamides against penicillin-resistant S. aureus has been promoted [84]. Bruyndonckx et al, (2021) reported that lincosamides were among the most consumed classes in Sweden and accounted for more than 20% of macrolides, lincosamides and streptogramins consumption in Austria, Finland, Germany, Hungary, and Luxembourg between 1997 and 2017 [52].…”

The first traces of Tetracycline (TE) were detected in human skeletons from Sudan and Egypt, finding that it may be related to the diet of the time, the use of some dyes, and the use of soils loaded with microorganisms, such as Streptomyces spp., among other microorganisms capable of producing antibiotics. However, most people only recognise authors dating between 1904 and 1940, such as Ehrlich, Domagk, and Fleming. Antibiotics are the therapeutic option for countless infections treatment; unfortunately, they are the second most common group of drugs in wastewaters worldwide due to failures in industrial waste treatments (pharmaceutics, hospitals, senior residences) and their irrational use in humans and animals. The main antibiotics problem lies in delivered and non-prescribed human use, use in livestock as growth promoters, and crop cultivation as biocides (regulated activities that have not complied in some places). This practice has led to the toxicity of the environment as antibiotics generate eutrophication, water pollution, nutrient imbalance, and press antibiotic resistance. In addition, the removal of antibiotics is not a required process in global wastewater treatment standards. This review aims to raise awareness of the negative impact of antibiotics as residues and physical, chemical, and biological treatments for their degradation. We discuss the high cost of physical and chemical treatments, the risk of using chemicals that worsen the situation, and the fact that each antibiotic class can be transformed differently with each of these treatments and generate new compounds that could be more toxic than the original ones; also, we discuss the use of enzymes for antibiotic degradation, with emphasis on laccases.

“…Among the species included in the genus, Staphylococcus aureus is the most clinically important, its incidence varies between 10 to 30 cases per 100 000 people per year, in which the most affected ages are at the extremes of life (children and the elderly), being the black population was shown to be prevalente [12,13].…”

Introduction: Laboratory diagnosis related to clinical microbiology is highly complex, due to subjectivity when interpreting the results. Among bacterial pathogens, those linked to the Staphylococcus genus are relevant from a clinical and epidemiological point of view. Aim: To review the literature relative to the main laboratory methods used for the isolation and identification of microorganisms of the genus Staphylococcus. Methodology: The study was based on a literature search between 2000 and 2020, in the BVS, PubMed, Scielo, ScienceDirect and CAPES Periodical databases. Regarding its laboratory diagnosis, microscopy is used by the Gram method to verify the bacterium’s morphology; novobiocin test, aiming to trace coagulase negative strains; use of biochemical tests, such as coagulase and catalase tests; identification through the use of selective and nonspecific culture media, such as blood agar (in which the hemolytic patterns of pathogens are observed), salty mannitol agar (specific to the species of Staphylococcus aureus) and DNAse agar (selective to S. aureus strains , S. intermedius and S. hyicus). Results: The Staphylococcus genus is of great clinical importance in the field of public health. Thus, the quality and speed of diagnosis are essential to promote measures to combat these pathogens, contributing to the well-being and survival of those affected.
